8 pounds. Because you'll need 4 pounds to make 10 apple pies, 6 pounds to make 15 apple pies, and 8 pounds to make 20 apple pies.
Division is repeated subtraction, just like multiplication is repeated addition. If you divide 50 by 10, you get 5. This is also the question: How many times do you have to subtract 10 from 50 to get 0?
Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V =
, where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V = ![\frac{(12)(7)}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%2812%29%287%29%7D%7B3%7D)
V = 28 ft³
