A pizza is 14 inches in diameter. Each square inch of pizza has 14.04 calories. If each slice contains about 270 calories, how m
mr Goodwill [35]

Answer:

8 slices

Step-by-step explanation:

To answer this question, we first need to know the area covered by the pizza.

Since it is circular in shape, we use the formula for the area of a circle.

Mathematically area of a circle = pi * r^2

Here, we were given the diameter but we know that D = 2r or r = D/2. This shows that the radius would be 14/2 = 7 inches

Now the area of the pizza is 22/7 * 7 * 7 = 22 * 7 = 154 square inch

Now we proceed to calculate the amount in calories present in the pizza;

That would be 154 * 14.04 = 2162.16 calories

one slice has 270 calories; The number of slices in 2162.16 calories would be 2162.16/270 = 8.008 which is approximately 8 slices

Answer:

(x, y) = (-9, -1)

Step-by-step explanation:

Start by graphing two equations on the graph through the y-intercept and the slope.

Since they have different slope, they would intercept somewhere on the graph, which you can see clearly where they intercept from the drawing I included below.
