It's important to note that ordering more than 15 slices would exceed your budget of $48, while ordering fewer slices would allow you to save money for other expenses.

To determine how many pizza slices you can order with $48, we divide the total amount of money by the cost of each slice of pizza, which is $3.20. This gives us:

48 ÷ 3.20 = 15

So you can order up to 15 slices of pizza with $48. However, since you cannot order a fraction of a slice, the actual number of slices must be a whole number. Therefore, the possible numbers of pizza slices you can order are:

0 slices

1 slice

2 slices

3 slices

4 slices

5 slices

6 slices

7 slices

8 slices

9 slices

10 slices

11 slices

12 slices

The total amount of water supplied per hour inside a circle of radius 14 is approximately79.90 ft^3 per hour, and the total amount of water that goes through the sprinkler per hour is approximately  2π ft^3 per hour. As R approaches infinity, the total amount of water supplied per hour approaches  2 ft^3 per hour.

To find the total amount of water supplied per hour inside of a circle of radius 14, we need to integrate the function e^(-r) over the region of the circle total amount of water = ∫∫ e^(-r) dA

where the integration is over the circular region of radius 14, and dA is the differential area element.

Using polar coordinates, we can write dA = r dr dθ, and the limits of integration are 0 ≤ r ≤ 14 and 0 ≤ θ ≤ 2π. Substituting these values, we get:

total amount of water = ∫(0 to 2π) ∫(0 to 14) e^(-r) r dr dθ

Integrating with respect to r first, we get:

total amount of water = ∫(0 to 2π) [-e^(-r)](0 to 14) dθ

total amount of water = ∫(0 to 2π) (1 - e^(-14)) dθ

total amount of water = (1 - e^(-14)) ∫(0 to 2π) dθ

total amount of water = 2π(1 - e^(-14))

Thus, the total amount of water supplied per hour inside of a circle of radius 14 is approximately 79.90 ft^3 per hour.

To find the total amount of water that goes through the sprinkler per hour, we need to integrate the function e^(-r) over the entire plane:

total amount of water = ∫∫ e^(-r) dA

where the integration is over the entire plane, and dA is the differential area element.

Using polar coordinates, we can write dA = r dr dθ, and the limits of integration are 0 ≤ r ≤ ∞ and 0 ≤ θ ≤ 2π. Substituting these values, we get:

total amount of water = ∫(0 to 2π) ∫(0 to ∞) e^(-r) r dr dθ

Integrating with respect to r first, we get:

total amount of water = ∫(0 to 2π) [-e^(-r)](0 to ∞) dθ

total amount of water = ∫(0 to 2π) (1) dθ

total amount of water = 2π

Thus, the total amount of water that goes through the sprinkler per hour is exactly 2π ft^3 per hour.

To calculate the total amount of water supplied per hour inside a circle of radius R, then let R → ∞, we can use the result from part B and multiply it by the ratio of the areas of the two circles:

total amount of water = (total amount of water inside circle of radius R) × (area of circle of radius R)/(area of entire plane)

total amount of water = (2πR^2(1-e^(-R))) / (πR^2)

total amount of water = 2(1-e^(-R))

Now we can let R → ∞:

total amount of water = 2

Thus, the total amount of water supplied per hour inside a circle of infinite radius is exactly 2 ft^3 per hour.

Triangle XYZ will be translated to X'Y'Z' and the coordinates of Z' are (6,7).

A transformation known as a translation involves shifting each point in an image uniformly in one direction. It is also a type of transformation where every point in a figure is moved by the same amount in the same direction, producing a new figure that is identical to the original.

From the graph,

The coordinates of X are (7, 11)

The coordinates of Y are (10, 14)

The coordinates of Z are (8, 7)

When triangle XYZ is translated to X'Y'Z', the X-coordinate is given as (5, 11), which means the X-coordinate shifts left 2 points, so we need to subtract 2 from X-coordinate and keep Y-coordinate as it is.

Therefore the coordinate of the triangle X'Y'Z' are as follows,

The coordinates of X' are (7-2, 11) = (5,11)

The coordinates of Y' are (10-2, 14) = (8, 14)

The surface area of the triangular prism is 891 square inches, calculated by finding the area of each face (two triangular and three rectangular) and adding them up.

To find the surface area of the triangular prism, we need to find the area of each face and add them up.

The triangular prism has two identical triangular faces and three rectangular faces. The triangular faces have base 9 inches, height 12 inches, and hypotenuse 15 inches. The area of each triangular face can be found using the formula for the area of a triangle:

Formula for area of each triangular face = (1/2) x base x height

= (1/2) x 9 x 12

= 54 square inches

The prism also has three rectangular faces, each with length equal to the base of the triangle (9 inches) and width equal to the height of the prism (29 inches). The area of each rectangular face can be found using the formula for the area of a rectangle:

Area of each rectangular face = length x width

= 9 x 29

= 261 square inches

Hence, the triangular prism's total surface area is:

Total surface area = 2(Area of each triangular face) + 3(Area of each rectangular face)

= 2(54) + 3(261)

= 108 + 783

= 891 square inches

Therefore, the surface area of the triangular prism is 891 square inches.

We know that the total number of cookies is 99, so we can write an equation:

x + (1/2)x + (1/3)x = 99

To solve for x, we can first find a common denominator:

(6/6)x + (3/6)x + (2/6)x = 99

(11/6)x = 99

x = (6/11) * 99

x = 54

We cannot determine the exact number of votes for Tim or Selena without additional information. However, we can determine the fraction of the whole class that voted for each candidate based on the given information.

If only one third of the students cast votes, that means that two thirds did not vote. Therefore, the fraction of the whole class that voted for Tim and Selena is each equal to one third of the total number of students.

To calculate these fractions, we can use the following formula:

Fraction of class = Number of students who voted / Total number of students

Let's assume that there are N students in the class. Then, the number of students who voted for Tim is (1/3)N, and the number of students who voted for Selena is also (1/3)N.

So, the fraction of the whole class that voted for Tim is:

(1/3)N / N = 1/3

Similarly, the fraction of the whole class that voted for Selena is also 1/3.

Since we don't know the exact number of votes for each candidate, we cannot determine who received more votes.

f(1) = [tex]-(1)^2[/tex] + 20(1) + 50 = 69

f(10) = [tex]-(10)^2[/tex] + 20(10) + 50 = 150

Hence, the change in f(x) throughout the range [1,10] is as follows:

f(10) - f(1) = 150 - 69 = 81

And the interval [1,10] has the following length:

10 - 1 = 9

Thus, from year one to year ten, the average rate of change is:

(150 - 69)/9 = 9

By interpreting the average rate of change, we can conclude that from year 1 to year 10, the farmer's land's yield of maize per acre is growing at a pace of 9 pounds each year.

It will take 2.2 hours for the two trains to meet.

We can find the time taken by the two trains to meet by using the formula,

large Time=Distance/Speed

Let's consider the time taken by the two trains to meet be "t".The distance between two trains = 418 miles.

Now, the first train is traveling at a speed of 85 mph and the second train is traveling at a speed of 105 mph.

Let's calculate the distance covered by both the trains in time "t".The distance covered by the first train in time "t"=85t.

The distance covered by the second train in time "t"=105t.

So, the total distance covered by both the trains in time "t" is,

Distance covered = 85t+105t=190t.

But we know the distance between the two trains is 418 miles.

Therefore,190t = 418

The rate at which the height of the water is increasing when water is being pumped in at a rate of 2/3 m/s and the water is 9m deep is 0.667 m/s.

We can start by using the formula for the volume of a square pyramid to find the volume of water in the tank. Let V be the volume of water in the tank and h be the height of the water.

V = (s² [h])/3

We know that the base of the pyramid is 3m by 3m, so s = 3. Also, the height of the pyramid is 16m, so we have:

V = (3² [h])/3

V = 3h

Now, we can find the rate of change of the volume with respect to time:

dV/dt = 3 [dh/dt]

We know that water is being pumped in at a rate of 2/3 m/s, so dh/dt = 2/3. We want to find how fast the height increases when the water is 9m deep, so h = 9. Substituting these values, we get:

dV/dt = 3 [dh/dt]

dV/dt = 3 [2/3]

dV/dt = 2

Therefore, the rate at which the volume of water is increasing is 2 cubic meters per second. To find the rate at which the height of the water is increasing, we need to solve for dh/dt:

dV/dt = 3 [dh/dt]

2 = 3 * dh/dt

dh/dt = 2/3

So the height of the water is increasing at a rate of 2/3 m/s when the water is 9m deep. Rounded to 3 decimal places, the answer is 0.667 m/s.

probability = 1/10

probability = 0.10.

Thus, the correct option is A: the probability distribution for the winning ticket:

1          2        3       4      5      6       7       8       9      10

0.10  0.10  0.10  0.10  0.10  0.10  0.10  0.10  0.10  0.10
