What is the measure of angle?

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Here, we have

Given: The measures of 5 of the interior angles of a hexagon are: 130, 120°, 80, 160, and 155. we have to find the measure of the largest interior angle.

The sum of all the six interior angles of a hexagon is 720°.

As sum of five angles is 130° + 120° + 80° + 160° +155° = 165°

The sixth angle is 720° - 165° = 75°

So the smallest interior angle of the hexagon is 75°.

and the largest exterior angle is 180° -  75° =  105°.

Hence, the measure of the largest interior angle is  105°.

At the school bookstore, Rylan bought two spiral notebooks and one folder and paid $6. 70. Olivia bought three spiral notebooks and five folders and paid $12. 85. Find the cost of each folder

Answers

To find the cost of each folder, we need to first set up a system of equations based on the given information. Let x be the cost of a spiral notebook and y be the cost of a folder. We can create the following equations:

1)  2x + y = $6.70 (Rylan's purchase)


2)  3x + 5y = $12.85 (Olivia's purchase)

First, we can solve equation 1 for y:

y = $6.70 - 2x

Next, substitute this expression for y into equation 2:

3x + 5($6.70 - 2x) = $12.85

Now, solve for x:

3x + $33.50 - 10x = $12.85

Combine like terms:

-7x = -$20.65

Now, divide by -7:

x = $2.95

Now that we know the cost of a spiral notebook, we can plug this value back into the expression we found for y:

y = $6.70 - 2($2.95)

y = $6.70 - $5.90

y = $0.80

So, the cost of each folder is $0.80.

The total weight of a shipping crate is modeled by the function c = 24b + 30, * where c is the total weight of the crate with b boxes packed inside the crate. If each crate holds a maximum of 6 boxes, then what are the domain and range of the function for this situation?

Answers

The domain of the function is 0 ≤ b ≤ 6, and the range of the function is 30 ≤ c ≤ 174.

Understanding Domain of a Function

The function that models the total weight of a crate with b boxes inside is given as:

c = 24b + 30

We know that each crate can hold a maximum of 6 boxes. Therefore, the number of boxes inside the crate can only take values from 0 to 6.

Domain:

The number of boxes b can take values from 0 to 6. Therefore, the domain of the function is:

0 ≤ b ≤ 6

Range:

To find the range of the function, we need to consider the maximum and minimum values that c can take when

0 ≤ b ≤ 6.

When b = 0, the crate is empty, and the total weight of the crate is:

c = 24(0) + 30 = 30.

When b = 6, the crate is full with 6 boxes, and the total weight of the crate is:

c = 24(6) + 30 = 174.

Therefore, the range of the function is:

30 ≤ c ≤ 174

We can then say the domain of the function is 0 ≤ b ≤ 6, and the range of the function is 30 ≤ c ≤ 174.

Answers

The area of the sector is approximately 23.24 m^2.

How to find the area?

To find the area of the sector, we first need to find the central angle of the sector.

The entire circumference of the circle is given by 2πr, where r is the radius of the circle. In this case, the circumference is 2π(3) = 6π m.

The arc length given is 47 m, which we can use to find the central angle of the sector:

central angle = (arc length / circumference) × 360°

central angle = (47 / 6π) × 360°

central angle ≈ 299.02°

Now that we have the central angle, we can use the formula for the area of a sector:

area of sector = (central angle / 360°) × πr^2

area of sector = (299.02 / 360) × π(3)^2

area of sector ≈ 7.43π m^2

Rounding to two decimal places, the area of the sector is approximately 23.24 m^2.

Then, find it by breaking the circle into equal sectors and rearranging the sectors as a parallelogram. Show all calculations. Use π, instead of an approximation, in your answers. Round to the nearest tenth

Answers

Using the formula for the area of a circle:

A = πr^2

A = π(4m)^2

A = 16π

A ≈ 50.3 m^2

Breaking the circle into equal sectors and rearranging the sectors as a parallelogram:

We can break the circle into 8 equal sectors, like this:

[IMAGE: circle with 8 equal sectors]

Each sector is 1/8th of the circle, so its angle is 45°. We can rearrange the sectors to form a parallelogram, like this:

[IMAGE: parallelogram made up of 8 sectors of the circle]

The base of the parallelogram is the same as the circumference of the circle, which is 2πr:

base = 2πr

base = 2π(4m)

base = 8π

The height of the parallelogram is the radius of the circle, which is 4m.

Now we can find the area of the parallelogram:

A = base × height

A = 8π × 4m

A = 32π

A ≈ 100.5 m^2

Finally, we can divide the area of the parallelogram by 8 to get the area of the circle:

A = (area of parallelogram) ÷ 8

A = (32π) ÷ 8

A = 4π

A ≈ 12.6 m^2

Therefore, the area of the circle is approximately 50.3 m^2 (using the formula) or 12.6 m^2 (using the parallelogram method).

find the volume of the solid obtained by rotating the region bounded by 2 =8 32? and 2 = -2y about the line x= 9. round to the nearest thousandth.

Answers

The volume of the solid obtained by rotating the region about the line x=9 is approximately 201.06 cubic units.

To find the volume of the solid obtained by rotating the region bounded by 2 =8 32? and 2 = -2y about the line x= 9, we can use the cylindrical shell method.

First, we need to sketch the region and the line of rotation:

  |         +---------+

8 |         |         |

  |         |         |

  |         +---------+ x=9

  |              

0 +---------------+

  0      4      8

The region is a rectangle with height 4 and width 8, centered at the origin. The line of rotation is x=9.

Now, we can express the volume of the solid as a sum of cylindrical shells:

V = ∫[0,4] 2πr h dx

where r is the distance between x=9 and the boundary of the region at height x, and h is the thickness of the shell.

Since the region is symmetric about the y-axis, we can consider only the right half of the region and multiply the result by 2 to get the total volume.

The equation of the boundary at height x is:

2 = -2y

y = -x/2

The distance between x=9 and this line is:

r = 9 - (-x/2) = 9 + x/2

The thickness of the shell is dx.

Substituting these values into the integral, we get:

V = 2 ∫[0,4] 2π(9 + x/2) dx

V = 2π ∫[0,4] (18 + x) dx

V = 2π [18x + (1/2)[tex]x^2[/tex]] from x=0 to x=4

V = 2π [(18*4 + (1/2)[tex]4^2[/tex]) - (180 + (1/2)*[tex]0^2[/tex])]

V = 64π ≈ 201.06

Therefore, the volume of the solid obtained by rotating the region about the line x=9 is approximately 201.06 cubic units.

Chris is using the expression 4x + 2 to represent the number of students in his gym class. There are four times as many students as basketballs, and there are two more students in the locker room. What does x represent? (4 points)

Answers

X represents the number of basketballs in Chris's gym class.

Chris represents the number of students in his gym class with the expression 4x + 2. We know that the number of students is four times the number of basketballs, so we can set up the equation 4x = the number of basketballs.

If we substitute this expression for the number of students in the gym class, we get 4(4x) + 2 = the total number of students in the gym class and locker room. We also know that there are two more students in the locker room, so we can add 2 to this expression to get 4(4x) + 4 = the total number of students in the gym class and locker room.

Now we can set this expression equal to the original expression for the number of students, 4x + 2, and solve for x:

4(4x) + 4 = 4x + 2

16x + 4 = 4x + 2

12x = -2

x = -1/6

However, x cannot represent a negative number of basketballs, so there must be an error in the problem.

______ft/sec

Answers

Solving for dz/dt, we get:

dz/dt ≈ 11.650 ft/sec.

So, after another minute, the distance between Claire and Anna is changing at a rate of approximately 11.650 ft/sec.

Hi there! To answer this question, we can use the Pythagorean theorem and implicit differentiation. Let x be the distance Claire runs east and y be the distance Anna runs north. After 1 minute, Claire has already run 12 * 60 = 720 ft. After another minute, x = 720 + 12t, and y = 7t.

Now, we can set up the Pythagorean theorem: x^2 + y^2 = z^2, where z is the distance between them. Substituting the expressions for x and y, we get (720 + 12t)^2 + (7t)^2 = z^2.

To find the rate at which the distance between them is changing (dz/dt), we need to differentiate both sides of the equation with respect to time, t:

2(720 + 12t)(12) + 2(7t)(7) = 2z(dz/dt).

Now, we can plug in the values for t = 2 minutes:

2(720 + 24)(12) + 2(14)(7) = 2z(dz/dt).

Simplifying, we get:

34560 + 392 = 2z(dz/dt).

After 2 minutes, Claire has run 12(120) = 1440 ft, and Anna has run 7(60) = 420 ft. Using the Pythagorean theorem, we can find z:

z = √(1440^2 + 420^2) ≈ 1500 ft.

what is the probability that amelie spins either an odd number or a red number?

Answers

The probability of Amelie spinning either an odd number or a red number is 0.6 or 60%.

The probability of Amelie spinning either an odd number or a red number can be found by adding the probability of spinning an odd number to the probability of spinning a red number and then subtracting the probability of spinning a number that is both even and not red.

First, let's find the probability of spinning an odd number. Out of the ten equally sized spaces on the spinner, five of them are odd (1, 3, 5, 7, and 9). Therefore, the probability of spinning an odd number is 5/10 or 1/2.

Next, let's find the probability of spinning a red number. Out of the ten equally sized spaces on the spinner, three of them are red (2, 4, and 6). Therefore, the probability of spinning a red number is 3/10.

Finally, we need to subtract the probability of spinning a number that is both even and not red. Out of the ten equally sized spaces on the spinner, two of them are even and not red (8 and 10). Therefore, the probability of spinning a number that is both even and not red is 2/10 or 1/5.

To find the probability of spinning either an odd number or a red number, we add the probability of spinning an odd number (1/2) to the probability of spinning a red number (3/10) and then subtract the probability of spinning a number that is both even and not red (1/5).

(1/2) + (3/10) - (1/5) = 0.6 or 60%

Answers

If the motion of a point on the drum of a clothes dryer is modeled by the function y=12 sin (4/3π t) +20, the dryer rotates 40 times per minute.

The function y = 12 sin (4/3π t) + 20 models the vertical motion of a point on the drum of a clothes dryer. The amplitude of the function is 12, which represents the maximum displacement of the point from its rest position. The vertical shift of the function is 20, which represents the height of the point from the ground when the drum is at rest.

To determine the number of times the dryer rotates per minute, we need to find the period of the function, which is the time it takes for the function to complete one full cycle. The period of a sinusoidal function is given by the formula:

T = (2π) / b

where b is the coefficient of the t variable in the sine or cosine function.

In this case, b = (4/3)π, so the period of the function is:

T = (2π) / (4/3π) = 3/2 seconds

This means that the point on the drum completes one full cycle of vertical motion every 3/2 seconds. To convert this to rotations per minute, we need to find the number of cycles per minute:

cycles per minute = (60 seconds per minute) / (3/2 seconds per cycle) = 40 cycles per minute

Since the function approaches the same value (0) along both paths, we can claim that the limit lim(x,y)→(0,0) f(x,y) exists and is equal to 0.

Your question is asking whether the limit of the function f(x,y) exists at the point (0,0). The function f(x,y) is defined as:
f(x,y) = x^2 + y if (x,y) ≠ (0,0)
f(x,y) = 0 if x = y = 0
To verify whether the limit exists, we need to check if the function approaches a unique value as (x,y) approaches (0,0). In other words, we need to determine if lim(x,y)→(0,0) f(x,y) exists.
To verify this claim, consider the function along different paths towards (0,0). Let's examine two paths:
1) x = 0: As x approaches 0, f(0,y) = y, and the limit becomes lim(y→0) y = 0.
2) y = x: As y approaches 0 along this path, f(x,x) = x^2 + x, and the limit becomes lim(x→0) (x^2 + x) = 0.

A mouse is moving through a maze and must make four turns where it can go either left or
right. The mouse will escape the maze if it makes three lefts and one right, in any order.
(a) To the right, draw a tree diagram
of all possible routes the mouse
could take.
(b) Using your tree diagram, create
an organized list of the routes. For
example, a route of right, left, left,
right could be listed as RLLR.
(C) What is the probability the mouse
escapes the maze if all turns are
randomly made?

Answers

Hence, 25% is the likelihood that the mouse will succeed in escaping the maze if all turns are made at random.

what is probability ?

The examination of random chance and the likelihood that they will occur is the focus of the mathematical field of probability. It is a gauge of how likely an event is to occur and is represented by a value between zero and 1. A probability of 1 indicates that an event will undoubtedly occur. The probability of an occurrence is zero if it cannot occur. An event's probability is 0.5, or 50%, when it possesses a 50/50 chance of occurring. The number of favourable outcomes is divided by the entire amount of possible results to determine probability.

given

Based on the tree diagram, the following is an orderly list of every route that might be taken:

Three left turns and one right turn, in whatever order, make up each route.

As there are two options (left or right) for each turn, there are a total of 24 = 16 potential sequences of four turns.

Only if the mouse makes precisely three left turns and one right out of these will it be able to escape the maze.

Three lefts and one right can be arranged in one of four distinct ways (LLL, LLR, LRL, RLL), so the likelihood that the mouse will elude the maze is:

P(escape) = Number of favourable results / Number of potential results = 4 / 16 = 0.25 = 25%

Hence, 25% is the likelihood that the mouse will succeed in escaping the maze if all turns are made at random.

D(x) is the price, in dollar per unit, that the consumers are willing to pay for x units of an item, and S(x) is the price, in dollars per unit, that producers are willing to accept for x units. Find (a) the equilibrium point, (b) the consumer surplus at the equilibrium point, and (c) the producer surplus at the equilibrium point.
D(x)=(x-7)^2, S(x)=x^2+2x+33
Find:
A) The equilibrium point
B) The consumer surplus at the equilibrium point
C) The producer surplus at the equilibrium point

Answers

32/9

So the producer surplus at the equilibrium point is 32/9 dollars.

To find the equilibrium point, we need to set D(x) equal to S(x) and solve for x:

(x-7)^2 = x^2 + 2x + 33

Expanding and simplifying:

x^2 - 14x + 49 = x^2 + 2x + 33

12x = 16

x = 4/3

So the equilibrium point is x = 4/3.

To find the consumer surplus at the equilibrium point, we need to find the difference between the maximum price consumers are willing to pay (D(4/3)) and the equilibrium price (S(4/3)) and multiply by the quantity sold (4/3):

Consumer surplus = (D(4/3) - S(4/3)) * (4/3)

= [(4/3 - 7)^2 - (4/3)^2 - 2(4/3) - 33] * (4/3)

= [49/9 - 16/9 - 8/3 - 33] * (4/3)

= -224/27

So the consumer surplus at the equilibrium point is -224/27 dollars.

To find the producer surplus at the equilibrium point, we need to find the difference between the equilibrium price (S(4/3)) and the minimum price producers are willing to accept (S(0)) and multiply by the quantity sold (4/3):

Producer surplus = (S(4/3) - S(0)) * (4/3)

= [(4/3)^2 + 2(4/3) + 33 - 33] * (4/3)

= 32/9

So the producer surplus at the equilibrium point is 32/9 dollars.

Answers

We can use the ratio test to determine whether the series ∑(n=1[tex])^(infinity)[/tex][tex]13^n[/tex]/ [(n+1)[tex]6^(2n+1)[/tex]] is convergent or divergent.

We evaluate the limit:

lim n → ∞ [tex]|(13^(n+1) / [(n+2)6^(2n+3)]) / (13^n / [(n+1)6^(2n+1)])|[/tex]

= lim n → ∞ [tex]|(13^(n+1) / 13^n) * [(n+1)6^(2n+1) / (n+2)6^(2n+3)]|[/tex]

= lim n → ∞ [tex]|13 / 6^2| * |(n+1)/(n+2)|[/tex]

= 13/36

Since the limit is less than 1, by the ratio test, the series is convergent.

To find the value of a_n, we can substitute n = 1 into the formula:

a_n = [tex]13^n / [(n+1)6^(2n+1)][/tex]

a_1 = [tex]13 / [(1+1)6^(2+1)] = 13 / (2*6^3)[/tex]

Therefore, a_1 = 13 / 432.

Note that we only needed to find the value of a_1 to apply the ratio test and determine the convergence of the series.

Gilberto Brought $36. 50 to the state fair. He bought a burger a souvenir and a pass. The burger was 1/3 as much as the souvenir and the souvenir cost 1/2 the cost of the pass. Gilberto had $4. 00 left over after buying these items

Answers

Gilberto brought $69.00 to the state fair.

How much money did Gilberto bring to the state fair originally?

Let's start by assigning variables to represent the unknown values in the problem:

Let x be the cost of the pass.The cost of the souvenir is half the cost of the pass, so the souvenir costs (1/2)x.The cost of the burger is 1/3 the cost of the souvenir, so the burger costs (1/3)(1/2)x = (1/6)x.

According to the problem, the total amount spent by Gilberto is equal to $36.50, so we can set up an equation:

x + (1/2)x + (1/6)x = 36.5

Simplifying the equation, we can combine the like terms:

(5/6)x = 36.5

To solve for x, we can multiply both sides by the reciprocal of 5/6:

x = 36.5 / (5/6) = $43.80

So the cost of the pass is $43.80. Using the values we assigned earlier, we can find the cost of the souvenir and the burger:

The souvenir costs half the cost of the pass, which is (1/2)($43.80) = $21.90.The burger costs 1/3 the cost of the souvenir, which is (1/3)($21.90) = $7.30.

Therefore, Gilberto spent $43.80 on the pass, $21.90 on the souvenir, and $7.30 on the burger, for a total of $43.80 + $21.90 + $7.30 = $73.00.

However, we are also told that Gilberto had $4.00 left over after buying these items.

So we can subtract that from the total amount spent to get the initial amount of money that Gilberto brought to the fair:

$73.00 - $4.00 = $69.00

Therefore, Gilberto brought $69.00 to the state fair.
