Answer:
491,400 ft·lb
Step-by-step explanation:
The mass of the water is ...
M = Vρ = LWHρ = (25 ft)(15 ft)(7 ft)(62.4 lb/ft³) = 163,800 lb
The average depth is 3 ft, so the work required is equivalent to that required to raise this mass 3 ft.
W = (3 ft)(163,800 lb) = 491,400 ft·lb

Answer:
Step-by-step explanation:
14(8x-36)+2x
112x -504 +2x
114x-504
Answer: -17
Explanation: If g(x) = 4x - 5, then g(-3) = 4(-3) - 5 which simplifies to -17.
50 0+50 = 50 because 50-0=50
