Answer:
It will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
Step-by-step explanation:
Given that an inlet pipe can fill an empty swimming pool in 5hours, and another inlet pipe can fill the pool in 4hours, to determine how long it will take both pipes to fill the pool, the following calculation must be performed:
1/5 + 1/4 = X
0.20 + 0.25 = X
0.45 = X
9/20 = X
9 = 60
2 = X
120/9 = X
13,333 = X
Therefore, it will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.

Answer:
3%
Step-by-step explanation:
1. Set up the equation
6(0.18) + 12x = 18(0.08)
2. Simplify
1.08 + 12x = 1.44
3. Solve
12x = 0.36
x = 0.03
0.03 = 3%
For number 15, all you need to do is multiply 36 by 25 which gets you 900 square yards. For #16, you would also want to use multiplication, 3 * 39 ($117) , 4 * 15 ($60) and 27 * 2 ($54). Now add them together, 54 + 117 = 171 + 60 = $231. And finally break down the number 309 million, 058 thousand, 304 hundred. Four, eight and, nine need to be in the ones place. So you have 309,058,304, C.
