A rectangular tank that is 4 feet long, 5 feet wide and 15 feet deep is filled with a heavy liquid that weighs 110 pounds per cubic foot. In each part below, assume that the tank is initially full. Your answers must include the correct units. (You may enter lbf or lb*ft for ft-lb.)

How much work is done pumping all of the liquid out over the top of the tank?

247500 J

Step-by-step explanation:

We are given that

Length,l=4 feet

Width,b=5 feet

Height,h=15 feet

Weigh,w=110

We have to find the work done in pumping all of the liquid out over the top of the tank.

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
