Answer:
x = -7.5
Step-by-step explanation:
P = 600 + 1,500x − 100x^2
P = − 100x^2 + 1,500x + 600
x = -b/2a
1500/ (2 x -100)
x = -7.5
Answer: ~2.45 cups, or A
Step-by-step explanation:
First, find the area of the circle. Area formula is
, but instead of the radius, we have the diameter. Halve the diameter to get the radius of 10 inches.
A = pi * 100
So the pizza has an area of around ~314.15 square inches.
Divide this number by 16 square inches to find how many 1/8 cups Tony uses.
314.15/16 = ~19.63 1/8 cups.
You can then divide 19.63 by 8 to receive how many cups he uses.
