Answer:
54
Step-by-step explanation:
20 ÷ a + 7 • b
Let a = 4 and b = 7
20 ÷ 4 + 7 • 7
Multiply and divide first
5 + 49
Then add
54
1) = 7 (to the power of 4)
2) = b (to the power of 2)
3) = 3 (to the power of 5)
4) = -2 (to the power of 5)
Step-by-step explanation:
a)U={1,3,4,5}
b)={1,3,5}
Assuming 8ft is the radius and 12ft is the height, the answer is approximately V=2412m^3
