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:
y=11/5
Step-by-step explanation:
first divide by 5 on both sides
y+2/5=-13/5
subtract 2/5 on both sides to isolate the y
y=11/5

Answer:
30°
Step-by-step explanation:
Use that
-the sum of angles in a triangle is 180° and that
-vertical angles are congruent ( angle x and the missing angle in the bottom triangle are vertical)
x= 180-75 -75 = 30°
Answer: B: It gets flatter
Step-by-step Explanation:
Slope is basically a ratio of the change in the x-value over the change in the y-value over a certain interval. It also shows how steep the line is. The higher (or further away from 0) the slope, the “steeper” the line is. If the slope is 0, the graph just looks like a horizontal line
