An oil tank is cylindrical in shaped. The diameter is 100 feet and the height is 30 feet. If oil is drained at a rate of 6000 cubic feet per minute, then how many minutes will it take to drain the oil tank.

39 minutes (rounded to nearest minute from 39.2699)

Step-by-step explanation:

π(50)^2*30= 235619.449/6000=39.2699

round to nearest minute: 39 minutes

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
