You need to divide both numbers by 7 because you currently know how many gallons are pumped in 7 minutes, and we want to find out how much is pumped in one minute.

42 ÷ 7 = 6.
7 ÷ 7 = 1.

So it pumps 6 gallons per minute.

The <em><u>correct answer</u></em> is:

6 gallons per minute.

Explanation:

In order to have a unit rate, we must have a rate with a denominator of 1. Our rate is 42/7. To make this a unit rate, we need to divide the denominator by 7. What we do to the denominator, we must also do to the numerator; this means we have (42÷7)/(7÷7) = 6/1. This is a rate of 6 gallons per minute.

Diameter of 6x and height of 2x+5 what is the volume of the cylinder

Answer:

V = pi*x^2*(18x - 45)

Step-by-step explanation:

If the diameter is 6x and the height is 2x + 5, we know that the radius is 3x.

Plugging this info into the volume-of-a-cylinder formula V = pi*r^2*h, we get:

V = pi*(3x)^2*(2x - 5), or V = pi*(9x^2)(2x -5), or:

V = pi*(18x^3 - 45x^2), or V = pi*x^2*(18x - 45)
