Given YZ tangent to ⊙J at point Y and m∠WYZ = 104, what is mWXY?

The greatest number of tables that can be made is 18 (since 18 is a factor of 72 and we have enough centerpieces to decorate 18 tables).

How to make the  greatest number of tables?

To determine the greatest number of tables that can be made, we need to find the number of chairs needed for each table, as well as the number of centerpieces that can be made with the available supplies.

Since we have 72 chairs and want to distribute them equally among the tables, we can start by finding factors of 72. Factors are numbers that can be multiplied together to get the original number. For example, the factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.

We can see that 72 can be divided equally into 2, 3, 4, 6, 8, 9, 12, and 18 tables. However, we also need to make sure that we have enough centerpieces to decorate each table.

To make a centerpiece, we need one balloon, one flower, and one candle. So we need to make sure that we have enough of each item to make the necessary number of centerpieces.

If we use all 48 balloons, 24 flowers, and 32 candles, we can make a maximum of 24 centerpieces (since we have only 24 flowers). This means that we can only have a maximum of 24 tables.

Therefore, the greatest number of tables that can be made is 18 (since 18 is a factor of 72 and we have enough centerpieces to decorate 18 tables).

To summarize, we can make a maximum of 18 tables, with each table having 4 chairs and one centerpiece made of one balloon, one flower, and one candle. This ensures that everything is distributed equally and there are no shortages.

To find the equation of the plane, we first need to find two vectors that lie on the plane. We can do this by taking the differences between the three given points:

$\vec{v_1} = \begin{pmatrix}6 \\ 0 \\ 3\end{pmatrix} - \begin{pmatrix}0 \\ 0 \\ 0\end{pmatrix} = \begin{pmatrix}6 \\ 0 \\ 3\end{pmatrix}$

$\vec{v_2} = \begin{pmatrix}-3 \\ -1 \\ 5\end{pmatrix} - \begin{pmatrix}0 \\ 0 \\ 0\end{pmatrix} = \begin{pmatrix}-3 \\ -1 \\ 5\end{pmatrix}$

Now we can find the normal vector to the plane by taking the cross product of these two vectors:

$\vec{n} = \vec{v_1} \times \vec{v_2} = \begin{pmatrix}6 \\ 0 \\ 3\end{pmatrix} \times \begin{pmatrix}-3 \\ -1 \\ 5\end{pmatrix} = \begin{pmatrix}3 \\ -27 \\ 6\end{pmatrix}$

Next, we can use the point-normal form of the equation of a plane:

$(\vec{r} - \vec{a}) \cdot \vec{n} = 0$

where $\vec{a}$ is a point on the plane and $\vec{n}$ is the normal vector.

We can choose any of the three given points as $\vec{a}$. Let's use $(0, 0, 0)$:

$(\begin{pmatrix}x \\ y \\ z\end{pmatrix} - \begin{pmatrix}0 \\ 0 \\ 0\end{pmatrix}) \cdot \begin{pmatrix}3 \\ -27 \\ 6\end{pmatrix} = 0$

Simplifying, we get:

$3x - 27y + 6z = 0$

This is the equation of the plane.
To find the equation of the plane passing through points (0, 0, 0), (6, 0, 3), and (-3, -1, 5), first find two vectors in the plane and then compute their cross product to obtain the normal vector of the plane. Finally, use the normal vector and a point on the plane to find the equation of the plane.

Vectors in the plane:
V1 = (6, 0, 3) - (0, 0, 0) = (6, 0, 3)
V2 = (-3, -1, 5) - (0, 0, 0) = (-3, -1, 5)

Cross product (normal vector N):
N = V1 x V2 = (0*(-5) - 3*(-1), 3*(-5) - 6*5, 6*(-1) - 0*(-3))
N = (3, -15, -6)

Equation of the plane using the normal vector and a point on the plane (0, 0, 0):
3x - 15y - 6z = 0

So, the equation of the plane is 3x - 15y - 6z = 0.

The rate of increase, we can see that the function is an exponential growth model with a base of 1.04, which means that the population increases by 4% each year.

There seems to be an error in the problem statement. If the function P(x) = 88,200(1.04)^x models the population after the year 2002, then it doesn't make sense to ask for the population in the year 2000, which is two years before 2002.

Assuming that the function is correctly stated and represents the population after 2002, we can find the population after a certain number of years by plugging that number into the function. For example, to find the population after 5 years (in 2007), we would use:

P(5) = 88,200(1.04)^5 = 105,159.43

This means that the population of the city in 2007 would be approximately 105,159 people.

The child can make 120 different bracelets using one of each charm. To solve this problem, we need to use a combinatorial approach.

The number of different bracelets that the child can make depends on the number of charms that can be used for each bracelet & the order in which they are arranged. Since each charm can be used only once, we have to choose five charms out of the total of five available charms, which can be done in 5C5 ways.

We can think of this problem as a permutation problem. There are five distinct charms, and we need to choose five of them to make a bracelet. The order in which we choose the charms matters, as each order gives us a different bracelet. Therefore, we need to use the formula for permutations.

The formula for permutations is given by:

nPr = n! / (n-r)!

where n is the total number of objects, and r is the number of objects we want to choose.

For this problem, n = 5 (since there are five distinct charms), and r = 5 (since we want to choose all five charms).

Plugging these values into the formula, we get:

5P5 = 5! / (5-5)! = 5! / 0! = 5 x 4 x 3 x 2 x 1 / 1 = 120

Therefore, the child can make 120 different bracelets.

Alternatively, we can also think of this problem as a multiplication principle problem. There are five distinct charms, & we need to choose one charm out of five for the first position, one charm out of four for the second position, one charm out of three for the third position, one charm out of two for the fourth position, & one charm out of one for the fifth position.

Using the multiplication principle, we can multiply these numbers together to get the total number of different bracelets:

5 x 4 x 3 x 2 x 1 = 120

Therefore, the child can make 120 different bracelets using one of each charm.

The car can travel for 4 hours on one full tank of gas.

Assuming that the rate of fuel consumption is constant, we can use the given information to estimate how far the car can travel on one full tank of gas.

First, we need to find the capacity of the gas tank. Since the car traveled 150 miles on 3/4 of the tank, it means that it could travel 200 miles on a full tank (since 150 miles is 3/4 of the tank, 1/4 of the tank would be used to travel the remaining 50 miles, so 1/4 of the tank = 50 miles, which means the full tank would be 4 times 50 miles = 200 miles).

Next, we need to find the car's average speed. Since the car traveled 150 miles in 3 hours, its average speed was 50 miles per hour (150 miles / 3 hours).

Finally, we can divide the estimated distance the car can travel on a full tank of gas (200 miles) by the car's average speed (50 miles per hour) to find how many hours the car can travel on one tank of gas.

200 miles / 50 miles per hour = 4 hours

The coordinates of P and Q are P(5, 5) and Q(7, 7) respectively.

Let the centres of the circles be:

P (a, r)  and

Q (b, s)

where r and s are the radii of the circles.

Since the circles are tangent to the x-axis, we know that r = a and s = b.

Also, since the circles are tangent to each other, we have

a + b = PQ = 26

Let the point of contact of circle P with the x-axis be (p, 0)

Let the point of contact of circle Q with the x-axis be (q, 0).

Then, we know that

p + q = AB = 24

Using Pythagorean theorem, we can write:

(r² - p²) + (r² - (24 - p)²) = (s²- q²) + (s² - (24 - q)²)

Expanding and simplifying, we get:

2r² - 24r + 576 = 2s² - 24s + 576

Substituting r = a and s = b, and using the fact that a + b = 26, we get:

2a² - 24a + 576 = 2b² - 24b + 576

Simplifying further, we get:

a² - 12a + 288 = b² - 12b + 288

(a - b)(a + b - 12) = 0

Since a + b = 26, we have a - b = 0 or a + b - 12 = 0. The first case gives us a = b, which is not possible since the circles are tangent to each other. Therefore, we have a + b = 12.

Using substitution method to solve  the simultaneous equations:

a + b = 12

a + b = 26

We get a = 7 and b = 5.

Therefore, the centres of the circles P and Q are (7, 7) and (5, 5) respectively.

To find the area of the sector NPQ, we first need to find the measure of the central angle that intercepts the arc PQ. We know that the measure of angle NPQ is 104 degrees, and since it is an inscribed angle, its measure is half the measure of the central angle that intercepts the same arc. Therefore, the central angle measure is 208 degrees.

To find the area of the sector, we use the formula:

Area of sector = (central angle measure/360) x pi x radius^2

We know that the radius of circle P is NP = 9 units. Plugging in the values, we get:

Area of sector NPQ = (208/360) x pi x 9^2
= (0.5778) x 81pi

To evaluate the given integral using cylindrical coordinates, we need to first express the given solid E and the differential volume element dv in terms of cylindrical coordinates.

In cylindrical coordinates, the paraboloid z = 1 – x^2 - y^2 can be expressed as z = 1 – r^2, where r is the distance from the z-axis and θ is the angle made with the positive x-axis. Since the solid E lies in the first octant, we have 0 ≤ r ≤ √(1-z), 0 ≤ θ ≤ π/2, and 0 ≤ z ≤ 1 – r^2.

The differential volume element dv in cylindrical coordinates is given by dv = r dz dr dθ.

Substituting these expressions in the given integral, we get:

SITE . 742 + x^2 dv = ∫∫∫E (742 + r^2) r dz dr dθ

= ∫θ=0π/2 ∫r=0√(1-z) ∫z=0^(1-r^2) (742 + r^2) r dz dr dθ

= ∫θ=0π/2 ∫r=0√(1-z) [(742r + r^3/3) - (742r^3/3 + r^5/5)] dr dθ

= ∫θ=0π/2 ∫z=0^1 [247/3(1-z)^(3/2) - 185/6(1-z)^(5/2)] dz dθ

= ∫θ=0π/2 [98/15 - 185/21] dθ

= ∫θ=0π/2 [56/315] dθ

= [28/315]π

Therefore, the value of the given integral using cylindrical coordinates is [28/315]π.

To evaluate the given integral using cylindrical coordinates, we need to express the function and limits of integration in terms of cylindrical coordinates (r, θ, z). The conversion between Cartesian and cylindrical coordinates is given by:

x = r*cos(θ)
y = r*sin(θ)
z = z

The given function in the problem is z = 1 - x^2 - y^2. Substituting the expressions for x and y in terms of cylindrical coordinates, we get:

z = 1 - r^2(cos^2(θ) + sin^2(θ))
z = 1 - r^2

Now, we need to find the limits of integration for r, θ, and z. Since E is the solid in the first octant, the limits for θ are 0 to π/2. For r, the limits are 0 to √(1 - z), and for z, the limits are 0 to 1. Then, the integral becomes:

∫(0 to π/2) ∫(0 to √(1 - z)) ∫(0 to 1) (742 + r^2cos^2(θ) + r^2sin^2(θ)) * r dz dr dθ

George's new store will have a profit of $5,400 in its fifth month in business.

We are given two functions: r(x) = x^2 + 5x + 14 for revenue, and c(x) = x^2 - 4x + 5 for expenses. We are asked to find the meaning of (r - c)(5).

Step 1: Subtract c(x) from r(x) to find (r - c)(x)
(r - c)(x) = r(x) - c(x) = (x^2 + 5x + 14) - (x^2 - 4x + 5)

Step 2: Simplify the expression
(r - c)(x) = x^2 + 5x + 14 - x^2 + 4x - 5 = 9x + 9

The volume of the composite space figure is approximately 2818.33 cubic cm.

To find the volume of the composite space figure, we need to add the volumes of the rectangular prism and the rectangular pyramid.

The rectangular prism has a length of 26 cm, a width of 5 cm, and a height of 14 cm. So its volume is:

V_prism = length x width x height

V_prism = 26 cm x 5 cm x 14 cm

V_prism = 1820 cubic cm

The rectangular pyramid has a height of 23 cm and a rectangular base with a length of 26 cm and a width of 5 cm. To find its volume, we need to first find its base area:

A_base = length x width

A_base = 26 cm x 5 cm

A_base = 130 square cm

Then, we can use the formula for the volume of a pyramid:

V_pyramid = (1/3) x base area x height

V_pyramid = (1/3) x 130 square cm x 23 cm

V_pyramid = 998.33 cubic cm (rounded to the nearest hundredth)

To find the total volume of the composite space figure, we add the volumes of the prism and the pyramid:

V_total = V_prism + V_pyramid

V_total = 1820 cubic cm + 998.33 cubic cm

V_total = 2818.33 cubic cm (rounded to the nearest hundredth)

Therefore, the volume of the composite space figure is approximately 2818.33 cubic cm.

Answer: (a) To find the total number of fish that enter the lake over the 5-hour period from midnight to 5 A.M., we need to integrate the rate of fish entering the lake over this time period:

Total number of fish = ∫0^5 E(t) dt

Using the given function for E(t), we get:

Total number of fish = ∫0^5 (20 + 15 sin(πt/6)) dt

Using integration rules, we can solve this:

Total number of fish = 20t - (90/π) cos(πt/6) | from 0 to 5

Total number of fish = (100 - (90/π) cos(5π/6)) - (0 - (90/π) cos(0))

Total number of fish ≈ 121

Therefore, approximately 121 fish enter the lake over the 5-hour period.

(b) To find the average number of fish that leave the lake per hour over the 5-hour period, we need to calculate the total number of fish that leave the lake over this time period and divide by 5:

Total number of fish leaving the lake = L(0) + L(1) + L(2) + L(3) + L(4) + L(5)

Total number of fish leaving the lake = (4 + 20.1(0)^2) + (4 + 20.1(1)^2) + (4 + 20.1(2)^2) + (4 + 20.1(3)^2) + (4 + 20.1(4)^2) + (4 + 20.1(5)^2)

Total number of fish leaving the lake ≈ 257.5

Average number of fish leaving the lake per hour = Total number of fish leaving the lake / 5

Average number of fish leaving the lake per hour ≈ 51.5

Therefore, approximately 51.5 fish leave the lake per hour on average over the 5-hour period.

(c) To find the time when the greatest number of fish are in the lake, we need to find the maximum value of the function N(t) = E(t) - L(t) over the interval 0 ≤ t ≤ 8. We can do this by taking the derivative of N(t) with respect to t and setting it equal to zero:

N'(t) = E'(t) - L'(t)

N'(t) = (15π/6)cos(πt/6) - 40.2t

Setting N'(t) = 0, we get:

(15π/6)cos(πt/6) - 40.2t = 0

Simplifying and solving for t gives:

t ≈ 2.78 or t ≈ 6.22

Since 0 ≤ t ≤ 8, the time when the greatest number of fish are in the lake is t ≈ 2.78 hours after midnight (approximately 2:47 A.M.) or t ≈ 6.22 hours after midnight (approximately 6:13 A.M.).

To justify this, we can use the second derivative test. Taking the second derivative of N(t) gives:

N''(t) = -(15π2/36)sin(πt/6) - 40.2

At t ≈ 2.78, N''(t) is negative, which means that N(t) has a local maximum at this point. Similarly, at t ≈ 6.22, N''(t) is positive, which also means that N(t) has a local maximum at this point. Therefore, these are the times when the greatest number of fish are in the lake.

(d) To determine if the rate of change in the number of fish in the lake is increasing or decreasing at 5 A.M. (t = 5), we need to find the sign of the second derivative of N(t) at t = 5. Taking the second derivative of N(t) gives:

N''(t) = -(15π2/36)sin(πt/6) - 40.2

Plugging in t = 5, we get:

N''(5) = -(15π2/36)sin(5π/6) - 40.2

Simplifying, we get:

N''(5) ≈ -60.5

Since N''(5) is negative, the rate of change in the number of fish in the lake is decreasing at 5 A.M. (t = 5). This means that the number of fish entering the lake is decreasing faster than the number of fish leaving the lake, so the total number of fish in the lake is decreasing.

(a) Approximately 131 fish enter the lake over the 5-hour period from midnight to 5 A.M.

(b) The average number of fish that leave the lake per hour over the same period is approximately 14.8.

(c) The greatest number of fish in the lake occurs at time t = 2.94 hours, or approximately 2 hours and 56 minutes past midnight.

(d) The rate of change in the number of fish in the lake is increasing at 5 A.M.

(a) To find the total number of fish that enter the lake over 5 hours, we need to integrate the function E(t) from t=0 to t=5:

∫[0,5] E(t) dt = ∫[0,5] (20 + 15 sin(πt/6)) dt

This evaluates to approximately 131 fish.

(b) The average number of fish that leave the lake per hour can be found by calculating the total number of fish that leave the lake over 5 hours and dividing by 5:

∫[0,5] L(t) dt = ∫[0,5] (4 + 20.1t^2) dt

This evaluates to approximately 74 fish, so the average number of fish that leave the lake per hour is approximately 14.8.

(c) To find the time at which the greatest number of fish is in the lake, we need to find the maximum of the function N(t) = ∫[0,t] E(x) dx - ∫[0,t] L(x) dx over the interval [0,8]. We can do this by finding the critical points of N(t) and evaluating N(t) at those points. The critical point is at t = 2.94 hours, and N(t) is increasing on either side of this point, so the greatest number of fish is in the lake at time t = 2.94 hours.

(d) The rate of change in the number of fish in the lake at 5 A.M. can be found by calculating the derivative of N(t) at t=5. The derivative is positive, so the rate of change in the number of fish is increasing at 5 A.M.

The probability that at least one of Tom or Jerry are late for school is 0.4.

To find the probability that at least one of Tom or Jerry are late for school, we can use the formula:
P(T or J) = P(T) + P(J) - P(T and J)

Since we don't know the probability of Jerry being late (P(J)), we can use the complement rule:
P(J) = 1 - P(JC)
where JC represents the event that Jerry is not late for school.

Substituting the given probabilities:
P(T or J) = P(T) + [1 - P(JC)] - P(T and J)
P(T or J) = 0.25 + 0.3 - 0.15
P(T or J) = 0.4

Therefore, the probability that at least one of Tom or Jerry are late for school is 0.4.

The distance from point A to point B is approximately 13706.2 feet. Rounded to the nearest tenth of a foot, this is 164474.4 inches or 13706.2 / 12 ≈ 1142.2 feet.

Let's first draw a diagram to visualize the situation:

           Lighthouse

                |

                |  x

                |

                |

          A ------------ B

                y

In the diagram, A is the starting point of the boat, B is the point where the crew measures the angle of elevation to be 6 degrees, and Lighthouse is the location of the lighthouse. We are looking for the distance AB.

From point A, we can use the tangent of the angle of elevation to find the height of the lighthouse beacon above sea level:

tan(15°) = height / 1433 feet

height = 1433 feet * tan(15°) ≈ 383.6 feet

Similarly, from point B, we can find the height of the lighthouse beacon above sea level:

tan(6°) = height / (1433 feet + AB)

height = (1433 feet + AB) * tan(6°)

Now we can set these two expressions for height equal to each other, since they represent the same height:

1433 feet * tan(15°) = (1433 feet + AB) * tan(6°)

Multiplying both sides by the denominator of the right-hand side, we get:

1433 feet * tan(15°) = 1433 feet * tan(6°) + AB * tan(6°)

Subtracting 1433 feet * tan(6°) from both sides, we get:

AB * tan(6°) = 1433 feet * (tan(15°) - tan(6°))

Dividing both sides by tan(6°), we get:

AB = 1433 feet * (tan(15°) - tan(6°)) / tan(6°) ≈ 13706.2 feet

Therefore, the distance from point A to point B when rounded to the nearest tenth of a foot, this is 164474.4 inches or 13706.2 / 12 ≈ 1142.2 feet.

Answer: arc BC is 60

Step-by-step explanation: if AC is the diameter and AWB is 120 degrees,

diameter= half a circle (180)

180-120

=60

hope this helped!! (sorry if its wrong)

Answer:

[tex]\overset\frown{BC}=60^{\circ}[/tex]

Step-by-step explanation:

The diameter of a circle is a straight line that passes through the center of the circle and whose endpoints lie on the circle.

Since angles on a straight line sum to 180°, and AC is the diameter of circle W, then:

[tex]m \angle AWB + m \angle BWC = 180^{\circ}[/tex]

Given the measure of angle AWB is 120°:

[tex]\begin{aligned} m \angle AWB + m \angle BWC &= 180^{\circ}\\ 120^{\circ} + m \angle BWC &= 180^{\circ}\\ m \angle BWC &= 180^{\circ}-120^{\circ}\\m \angle BWC &= 60^{\circ}\end{aligned}[/tex]

The measure of an intercepted arc is equal to the measure of its corresponding central angle. Therefore:

[tex]\overset\frown{BC}=m \angle BWC=60^{\circ}[/tex]

Therefore, the measure of arc BC is 60°.

The expression that is equivalent is as shown in option J

The profit is maximized at $16,400 when the ticket price is $12.

To find the ticket price that maximizes the profit, we used the fact that the maximum or minimum value of a quadratic function occurs at its vertex. For a quadratic function in the form of P(x) = ax^2 + bx + c, the x-coordinate of the vertex can be found using the formula x = -b / 2a.

In this case, we were given the function [tex]P(x) = -100x^2 + 2400x - 8000,[/tex]where x represents the price per ticket. The coefficient of [tex]x^2[/tex] is negative, which tells us that the graph of this function is a downward-facing parabola. The vertex of this parabola represents the maximum value of the function.

Using the formula x = -b / 2a, we found the x-coordinate of the vertex to be x = -2400 / 2(-100) = 12. This means that a ticket price of $12 will maximize the profit.

To verify that this is indeed the maximum profit, we substituted x = 12 into the profit function P(x):

[tex]P(12) = -100(12)^2 + 2400(12) - 8000 = 16,400[/tex]

We can see that the profit is maximized at $16,400 when the ticket price is $12.

In summary, to find the ticket price that maximizes the profit, we used the formula x = -b / 2a to find the x-coordinate of the vertex of the quadratic function representing the profit from selling tickets to a musical. The maximum profit occurs at the ticket price that corresponds to the x-coordinate of the vertex.

To find the mean and mean absolute deviation of a data set, you need to follow these steps:

1. Find the mean: To find the mean of a data set, add up all of the values in the set and then divide that sum by the number of values in the set. For example, if your data set is {2, 4, 6, 8, 10}, you would add up all of the values (2+4+6+8+10=30) and then divide that sum by the number of values (5). So the mean of this data set is 30/5 = 6.

2. Find the mean absolute deviation:

To find the mean absolute deviation of a data set, you first need to find the absolute deviation of each value in the set from the mean.

To do this, subtract the mean from each value in the set (for example, if your data set is {2, 4, 6, 8, 10} and the mean is 6, you would subtract 6 from each value: 2-6=-4, 4-6=-2, 6-6=0, 8-6=2, 10-6=4).

Then, take the absolute value of each of these differences (|-4|=4, |-2|=2, |0|=0, |2|=2, |4|=4). Finally, find the mean of these absolute deviations by adding them up and dividing by the number of values in the set.

For the example data set above, the mean absolute deviation is (4+2+0+2+4)/5 = 2.4.

The arc length of the polar curve [tex]r = e^{8\theta}[/tex] from θ = 0 to θ = 5 is[tex]\int_0^5 \sqrt{(64e^{16\theta}+1)} d\theta[/tex].

To find the arc length of a polar curve, we use the formula:

L = [tex]\int_a^b \sqrt{[r(\theta)^2+(dr(\theta)/d\theta)^2]} d\theta[/tex]

where r(θ) is the equation of the polar curve, and a and b are the starting and ending values of θ, respectively.

In this case, the equation of the polar curve is[tex]r = e^{8\theta}[/tex], so we have [tex]r(\theta) = e^{8\theta}[/tex]}. To find dr(θ)/dθ, we use the chain rule of differentiation:

dr(θ)/dθ = d/dθ ([tex]e^{8\theta}[/tex]) = [tex]8e^{8\theta}[/tex]

So now we have r(θ) and dr(θ)/dθ, which we can plug into the formula for arc length:

L = [tex]\int_0^5 \sqrt{[e^{16\theta}+(8e^{8\theta})^2] }[/tex]dθ

Simplifying the expression inside the square root, we get:

L = [tex]\int_0^5 \sqrt{(64e^{16\theta}+1) }[/tex]dθ

Unfortunately, this integral cannot be evaluated in terms of elementary functions, so we leave the answer in this form. We can, however, approximate it using Simpson's method and it comes out to be approximately 1.3526 * 10⁸.

Answer:

density = 22.35 g/30 cm^3 = .745 g/cm^3

A is the correct answer.

Answer:

0.75

Step-by-step explanation:

The density of a material is defined as its mass per unit volume. In this case, we are given the mass of the wooden prism and its dimensions, so we can calculate its volume and then use the formula for density.

The volume of the rectangular prism is:

V = l x w x h = 3 cm x 2 cm x 5 cm = 30 cm³

where l, w, and h are the length, width, and height of the prism, respectively.

The density of the wooden prism is then:

density = mass / volume

density = 22.35 g / 30 cm³

density = 0.745 g/cm³

Therefore, the density of the wood that the rectangular prism is made of is 0.745 g/cm³.
