Frank's monthly credit card payment for consolidating his credit cards will be $467.29.

Option C is the correct answer.

We have,

To calculate the monthly credit card payment for consolidating Frank's credit cards, we can use the formula for the monthly payment on a loan:

[tex]M = P (r (1 + r)^n) / ((1 + r)^n - 1),[/tex]

where M is the monthly payment, P is the total loan amount (sum of all credit card balances), r is the monthly interest rate, and n is the number of months.

First, let's calculate the total loan amount:

Total loan amount = $2,380 + $4,500 + $1,580 + $900 = $9,360.

Next, let's calculate the monthly interest rate:

Monthly interest rate = APR / 12 = 18% / 12 = 1.5%.

Now, let's calculate the monthly payment using the formula:

[tex]M = $9,360 \times (0.015 (1 + 0.015)^{24}) / ((1 + 0.015)^{24} - 1).[/tex]

Using a calculator, we can compute the value of M:

Let's start by assigning variables to the unknowns in the problem:

- Let j be Jim's speed in miles per hour (in other words, the rate at which he walks).

- Let s be Steve's speed in miles per hour (in other words, the rate at which he runs).

- Let m be Matt's speed on his bike in miles per hour.

From the first sentence of the problem, we know that:

s = m + 4   (Steve runs 4 miles per hour slower than Matt rides his bike)

And from the second sentence, we know that:

j = s - 3   (Jim walks 3 miles per hour slower than Steve runs)

We want to find out how long it takes Jim to walk 25 miles and how long it takes Matt to ride his bike x miles. We can use the formula:

time = distance / rate

For Jim, we have:

time = 25 / j

For Matt, we have:

time = x / m

We also know that Steve runs 16 miles in the same time that Matt rides his bike 24 miles, so we can write:

16 / s = 24 / m

Substituting s = m + 4 and solving for m, we get:

16 / (m + 4) = 24 / m

16m = 24(m + 4)

16m = 24m + 96

8m = 96

m = 12

So Matt rides his bike at a speed of 12 miles per hour.

Now we can use the equations we set up earlier to solve for j and x:

j = s - 3

s = m + 4

j = (m + 4) - 3

j = m + 1

j = 13

x / m = 25 / j

x / 12 = 25 / 13

x = (25 * 12) / 13

x = 300 / 13

x ≈ 23.08

So it takes Jim 25 / 13 ≈ 1.92 hours to walk 25 miles, and it takes Matt 23.08 hours to ride his bike x = 300 / 13 ≈ 23.08 miles.

Therefore, the volume of the composite figure is approximately 419.05 cubic cm.

Volume is the amount of space occupied by a three-dimensional object or shape. It is measured in cubic units such as cubic centimeters, cubic inches, or cubic meters. The volume of an object can be calculated by multiplying the area of its base by its height, or by using specific formulas depending on the shape of the object. The volume of an object is an important parameter in many areas of science and engineering, such as physics, chemistry, fluid mechanics, and material science, as it allows us to determine how much space an object will occupy or how much material is needed to fill a container or build a structure.

Here,

The composite figure consists of a cylinder and two cones, so we need to find the volume of each of these shapes and add them together.

Volume of cylinder = πr²h

= π(4²)(5)

= 80π cubic cm

Volume of one cone = (1/3)πr²h

= (1/3)π(4²)(5)

= (1/3)(80π)

= 26.67π cubic cm

Volume of both cones = 2(26.67π)

= 53.34π cubic cm

Total volume of composite figure = Volume of cylinder + Volume of both cones

= 80π + 53.34π

The dimensions of the garden last year were 15 feet by 4 feet.

Let the length of the garden last year be L feet, and the width be W feet. We are given that the area of the garden last year was 60 square feet:

L * W = 60

This year, the garden is 1 foot wider and 3 feet shorter than last year's garden:

Length: L - 3

Width: W + 1

The area of the garden remains the same:

(L - 3) * (W + 1) = 60

Now we have two equations with two variables:

L * W = 60

(L - 3) * (W + 1) = 60

We can solve this system of equations using substitution or elimination. Let's use substitution. From equation 1, we can write L as:

L = 60 / W

Now substitute this expression for L in equation 2:

(60 / W - 3) * (W + 1) = 60

Simplify and solve for W:

60 + 60 / W - 3W - 3 = 60

Combine like terms:

60 / W - 3W = 3

Multiply both sides by W to eliminate the fraction:

60 - 3W² = 3W

Move all terms to one side:

3W² + 3W - 60 = 0

Divide the equation by 3:

W² + W - 20 = 0

Factor the quadratic equation:

(W + 5)(W - 4) = 0

The possible values for W are -5 and 4. However, since width cannot be negative, W must be 4 feet. Now, use the expression for L to find the length:

L = 60 / W = 60 / 4 = 15 feet

The Maximum volume of the largest rectangular box with edges parallel to the axes that can be inscribed in the ellipsoid [tex]9x^2 + y^2 + 36z^2 = 1[/tex]is 4/5.

To find the volume of the largest rectangular box with edges parallel to the axes that can be inscribed in the ellipsoid [tex]9x^2 + y^2 + 36z^2 = 1:[/tex]

We can use the hint provided.

By symmetry, we can assume that the rectangular box is in the first octant where x, y, and z are all positive.
Let the dimensions of the rectangular box be 2x, 2y, and 2z.

Then the volume of the rectangular box is V = 8xyz.
To maximize V, we need to find the maximum value of xyz that satisfies the equation of the ellipsoid.

Substituting 2x, 2y, and 2z into the equation of the ellipsoid, we get:
[tex](2x/3)^2 + (y/6)^2 + (2z/3)^2 = 1[/tex]
Multiplying both sides by 9/4, we get:
[tex](2x/3)^2 * (9/4) + (y/6)^2 * (9/4) + (2z/3)^2 * (9/4) = 9/4[/tex]
Simplifying, we get:
4x^2/9 + y^2/36 + 4z^2/9 = 1
We can see that this is the equation of an ellipsoid centered at the origin with semi-axes a = 3/2, b = 3, and c = 3/2.
By symmetry, we know that the maximum value of xyz will be achieved when x = y = z. Therefore, we need to find the value of x, y, and z that satisfy the equation of the ellipsoid and maximize xyz.
Substituting x = y = z into the equation of the ellipsoid, we get:
[tex]4x^2/9 + x^2/36 + 4x^2/9 = 1[/tex]
Simplifying, we get:
[tex]x^2 = 9/20[/tex]
Therefore, x = y = z = √(9/20).
Substituting these values into V = 8xyz, we get:
[tex]V = 8(√(9/20))^3 = 4/5[/tex]

The volume of the can of soup that the bear ate was approximately 4644.64 cubic inches.

To solve this problem, we need to make some assumptions about the can of soup. Let's assume that the can is cylindrical and that it is completely filled with soup. We also need to assume that the label covered the entire surface area of the can without any overlap.

The label is 22 inches tall and 9 inches wide, so it covered a total surface area of 22 x 9 = 198 square inches. Since the label completely covered the sides of the can without any overlap, we can use this surface area to find the surface area of the can itself.

The surface area of a cylinder is given by the formula A = 2πrh + 2πr², where r is the radius of the base of the cylinder, and h is the height of the cylinder. In this case, we know that the height of the cylinder is 22 inches (the height of the label), and the circumference of the base of the cylinder is 9 inches (the width of the label).

Using these values, we can solve for the radius of the cylinder:

9 = 2πr
r = 4.53 inches

Now we can use the formula for the surface area of a cylinder to solve for the volume of the can:

A = 2πrh + 2πr²
198 = 2π(22)(4.53) + 2π(4.53)²
198 = 634.26
A = πr²h

To find the measure of angle 1 when AB is tangent to circle P at point B, we must consider some properties of tangents and circles.

A tangent line to a circle is a line that touches the circle at exactly one point, known as the point of tangency. In this case, line AB is tangent to circle P at point B. A crucial property of tangents is that they are perpendicular to the radius of the circle at the point of tangency. Therefore, the radius PB of circle P is perpendicular to tangent AB at point B.

Now, let's examine angle 1. If angle 1 is the angle formed by the tangent AB and the radius PB at point B, then it is a right angle due to the aforementioned property. In this case, the measure of angle 1 is 90 degrees.

However, if angle 1 is not directly formed by the tangent and radius, more information is needed to determine its measure. For example, if angle 1 is an angle inside the circle, you would need to know the measure of other angles or lengths of chords within the circle to calculate it.

In summary, if angle 1 is formed by tangent AB and radius PB at point B, its measure is 90 degrees because tangents are perpendicular to the radius at the point of tangency. If angle 1 is not formed by the tangent and radius, additional information is required to determine its measure.

To solve the system of linear equations by elimination, we need to eliminate one of the variables by multiplying one or both equations by a constant so that the coefficients of one of the variables are equal in both equations. Then, we can subtract one equation from the other to eliminate that variable and solve for the remaining variable.

In this case, we can eliminate y by multiplying the first equation by -7 and the second equation by 6, so that the coefficients of y are equal in both equations:

-28x - 42y = -336

18x + 42y = 306

Adding these two equations together, we get:

-10x = -30

Dividing both sides by -10, we get:

x = 3

Now that we have solved for x, we can substitute this value into one of the original equations to solve for y. Using the first equation, we get:

4x + 6y = 48

4(3) + 6y = 48

12 + 6y = 48

Subtracting 12 from both sides, we get:

6y = 36

Dividing both sides by 6, we get:

y = 6

Therefore, the solution to the system of linear equations is x = 3 and y = 6.

5x10 − 80x2

= 5x2 (x8 - 16)

Therefore, we can rewrite the expression as 5x2(x8 - 16).

Part B:

To factor the entire expression completely, we need to use the difference of squares formula, which states that:

a2 - b2 = (a + b)(a - b)

In this case, we can rewrite the expression as:

5x2(x8 - 16) = 5x2[(x4)2 - (4)2]

Notice that x8 can be rewritten as (x4)2, and 80 can be factored into 4 x 20, which gives us 16 when squared.

Using the difference of squares formula, we can factor the expression further:

Therefore, we have: a = 250 degrees (longest side) a = 120 degrees b = 195 degrees (shortest side) Next, we need to use the triangle inequality theorem to determine which combinations of sides can form a triangle. For any two sides a and b, the third side c must satisfy the following condition: c < a + b Using this condition, we can determine the valid combinations of sides: - a + b > c: This is always true, since a and b are the longest and shortest sides, respectively. - a + c > b: This is true for all values of c, since a is the longest side. - b + c > a: This is true only when c > a - b.

Substituting the given values, we get: c > a - b c > 250 - 195 c > 55 Therefore, any side c that is greater than 55 can form a triangle with sides a and b. We can use this condition to count the number of valid triangles: - If c = 56, then we have one triangle. - If c = 57, then we have two triangles (c can be either adjacent side). - If c = 58, then we have three triangles (c can be any of the three sides). Continuing this pattern, we can count the number of triangles for each value of c: c = 56: 1 triangle c = 57: 2 triangles c = 58: 3 triangles c = 59: 4 triangles c = 60: 5 triangles c = 61: 6 triangles c = 62: 7 triangles c = 63: 8 triangles c = 64: 9 triangles c = 65: 10 triangles c = 66: 11 triangles c = 67: 12 triangles c = 68: 13 triangles c = 69: 14 triangles c = 70: 15 triangles c > 70: 16 triangles (since all three sides can form a triangle) Therefore, there are 16 possible triangles that can be formed with the given angles and side lengths.

The equation in standard form for the circle with center (8,0) and radius 3/3 is (x - 8)² + y² = 1

To write the equation in standard form for the circle with center (8,0) and radius 3/3, we can use the following formula for a circle in standard form:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius. In this case, the center is (8,0) and the radius is 3/3, which simplifies to 1. Now, we can substitute the values of h, k, and r into the equation:
(x - 8)² + (y - 0)² = 1²

Since (y - 0) is just y, we can simplify the equation to:
(x - 8)² + y² = 1
So, the equation in standard form for the circle with center (8,0) and radius 3/3 is:
(x - 8)² + y² = 1
In summary, we used the standard form equation for a circle, substituted the given values for the center and radius, and simplified the equation to obtain the final answer.

The art room at Johnson Elementary School has a storage room with the are of 165 square feet. The length of one wall is 15 feet. The width of the storage room 11 feet. The perimeter of the room is 52 feet.

Find the width of the storage room, we need to use the formula for area:
Area = Length x Width
We know that the area is 165 square feet and the length is 15 feet, so we can plug those values in and solve for the width:
165 = 15 x Width
Width = 11
So the width of the storage room is 11 feet.
Find the perimeter of the room, we need to add up the lengths of all four walls. We know that one wall is 15 feet, and since the opposite wall must also be 15 feet to maintain the same area, we can add up the remaining two walls:
Perimeter = 2 x (15 + Width)
Perimeter = 2 x (15 + 11)
Perimeter = 2 x 26
Perimeter = 52
So the perimeter of the storage room is 52 feet.

The width of the storage room 11 feet. The perimeter of the room is 52 feet.

Carla's right rectangular prism could have either a 3x4 or a 2x6 rectangle as the bottom layer, with a height of 2 units, to achieve the given volume of 24 cubic units.

Carla built a right rectangular prism using unit cubes, with a volume of 24 cubic units and a height of 2 units. To determine the possible figure for the bottom layer of the prism, we need to understand the relationship between the volume, height, and the base area.

The volume of a rectangular prism can be calculated using the formula: Volume = Base Area × Height. In Carla's case, the volume is 24 cubic units, and the height is 2 units. By rearranging the formula, we can find the base area: Base Area = Volume ÷ Height. Substituting the given values, Base Area = 24 ÷ 2, which equals 12 square units.

Now, we need to find a possible figure for the bottom layer with an area of 12 square units. Since the bottom layer is made of unit cubes, it must have whole-number dimensions. There are two possible rectangular figures that meet this requirement: 1) a 3x4 rectangle, and 2) a 2x6 rectangle. Both of these figures have an area of 12 square units (3x4 = 12 and 2x6 = 12) and can be formed using unit cubes.

Percentage of lifetime cost that was interest = $407.

Let's begin by finding the monthly payment that Hillary made to pay off her laptop over two and a half years.

If she paid off the $804 balance with identical monthly payments, then the total amount she paid is equal to the balance plus the interest:

Total amount paid = balance + interest

We can use the formula for the present value of an annuity to solve for the monthly payment, where PV is the present value (in this case, $804), r is the monthly interest rate (which we can find from the APR), n is the total number of payments (30 months), and PMT is the monthly payment:

PV = PMT * (1 - (1 + r)^(-n)) / r

We can solve this equation for PMT:

PMT = PV * r / (1 - (1 + r)^(-n))

The monthly interest rate is the annual percentage rate divided by 12, and the number of payments is the number of years times 12:

r = 0.1127 / 12 = 0.009391667

n = 2.5 * 12 = 30

Using these values, we get:

PMT = 804 * 0.009391667 / (1 - (1 + 0.009391667)^(-30)) = $33.00

So Hillary made 30 monthly payments of $33.00 to pay off her laptop.

Next, we can calculate the cost of electricity over six years. There are 365 days in a year, and 2 leap years in the six-year period, for a total of 6*365+2 = 2192 days.

At $0.27 per day, the total cost of electricity is:

2192 * $0.27 = $592.64

Now we can calculate the total cost of the laptop over six years.

Hillary paid $33.00 per month for 30 months, or a total of 30 * $33.00 = $990.00. She also paid $592.64 for electricity. Therefore, the total cost of the laptop is:

$990.00 + $592.64 = $1582.64

The interest she paid on her credit card is the difference between the total amount she paid and the cost of the laptop:

Interest = Total amount paid - Cost of laptop

Interest = $990.00 + interest on $804 balance - $804 - $592.64

Simplifying this expression, we get:

Interest = $185.36 + interest on $804 balance

To find the interest on the $804 balance, we can use the formula for compound interest, where P is the principal (in this case, $804), r is the annual interest rate (11.27%), and t is the time in years (2.5 years):

A = P*(1 + r/n)^(n*t)

Here, we can set the number of compounding periods per year, n, to 12 since the interest is compounded monthly. Substituting the given values, we get:

A = $804*(1 + 0.1127/12)^(12*2.5) = $1026.12

So the interest on the $804 balance is:

Interest on $804 balance = $1026.12 - $804 = $222.12

Plugging this value into our expression for Interest, we get:

Interest = $185.36 + $222.12 = $407.48

Finally, we can find the percentage of the lifetime cost of the laptop that was interest:

Percentage of lifetime cost that was interest = Interest / Total cost of laptop * 100%

Percentage of lifetime cost that was interest = $407.

The volume of the part of the ball p < 5 that lies between the cones φ = π/4 and φ = π/3 is 0.

To express the volume of the part of the ball p < 5 that lies between the cones φ = π/4 and φ = π/3, we first need to determine the limits of integration in spherical coordinates.
Since the ball has radius 5, we know that the limits on ρ are 0 and 5.

For the limits on φ, we know that the region of interest lies between the cones φ = π/4 and φ = π/3, which correspond to angles of 45 degrees and 60 degrees, respectively.

Therefore, the limits on φ are π/4 and π/3.
For the limits on θ, we know that the region of interest extends all the way around the ball, so the limits on θ are 0 and 2π.
Using these limits, we can express the volume of the region of interest as:
V = ∫∫∫E ρ sin φ dρ dθ dφ
where,

E is the region of interest defined by the limits on ρ, θ, and φ that we just determined.
Substituting the limits and the volume element in spherical coordinates,
Integrating with respect to θ, we have:
V = 0
Therefore, the volume of the part of the ball p < 5 that lies between the cones φ = π/4 and φ = π/3 is 0.

This result suggests that there may be an error in the problem statement or that the region of interest is not well-defined.
