Answer:
1.504×10⁶ ft·lb
Step-by-step explanation:
We understand the top of the oil in the tank is 12 ft below ground level, and the bottom of the tank is 8+18=26 ft below ground level. Then the average depth of the oil is (12+26)/2 = 19 ft below ground level.
The height of the oil in the tank is 26-12=14 ft, so the volume of it is ...
V = πr²h = π(6 ft)²(14 ft) = 504π ft³ ≈ 1583.36 ft³
__
So, the work required to raise that volume of oil to the surface is ...
(1538.36 ft³)(50 lb/ft³)(19 ft) = 1.504×10⁶ ft·lb
Answer:
5/7
Step-by-step explanation:
Make both of the fractions into improper fractions, 2 2/7 is 16/7 and 1 4/7 is 11/7, then, subtract the improper fractions numerators. 16-11=5.

ARE THERE ANY ANSWER CHOICES?
Step-by-step explanation:
-14,-10,-6,-2,2,6
Answer by Mimiwhatsup: I could easily subtract -14 from -10 to find out the sequence so they are adding four each time. That means the pattern will continue going on like this 10, 14, 18, 22 and so forth.
X x=8-y y
-2 -2=8-y 10
-1 -1=8-y 9
and so on
x is the input and y is the output
