A swimming pool is filled with 8,520 gallons of water. The pool begins to drain at a rate of 12 gallons per minute. Which equation can be used to find the number of minutes, m, it will take for the pool to be half full?

A. 8520 - 12m = 4260

Step-by-step explanation:

12m - gallons will drain for m min

8520 - 12m   - gallons will be left

8520/2 = 4260 should be left

So,

8520 - 12m = 4260

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
