Answer:230 feet
Step-by-step explanation: Divide 200/30 to find the percentage. 30% of 200 is 15. Add the percentage to 200. Subtract 215 - 25.50. Then add 40.50.
Mathematically, that is 12(8+t). Distribute the 12, and you get 96 + 12t, or 12t + 96.
<span>You can use the fact that the work done is equivalent to finding the center of mass of the water in the tank(which is at the center of the cylindrical cross section, which is 3 ft below the level to which the liquid is pumped. Call this distance h.
You then need the total mass of the liquid, volume X density=m. This is where pi comes in!
Work needed =mgh, where g is the gravitational acceleration.</span><span>
