Answer:
A) Associative Property of Addition
Step-by-step explanation:
<u><em>Associative Property of Addition</em></u>
Let A, B and C be any three real numbers
A+(B+C) = (A+B) + C
Given data
(20.4 + 3.75) + 4.25 = 20.4 + (3.75 + 4.25)
= 20.4 + 8.0
= 28.4
Since

is representing the number of gallons of water in the tub, we need to replace

with the number of gallons remaining in the tube to find the time. Fortunately, the problem is telling us just that: 17.8 gallons. The only thing left is replacing that value in the equation, and solve for

to find the time:




We can conclude that after
3 minutes <span>the tub will have 17.8 gallons of water remaining.</span>
Try going through the formula which is 2 pi r
so 2*3.14*7
