Answer:
- Nguyen family's sprinkler: 20 L per hour
- Reed family's sprinkler: 35 L per hour
Step-by-step explanation:
Let n and r represent the output in liters per hour of the Nguyen and Reed family sprinklers, respectively. Then we have ...
15n +25r = 1175 . . . . total sprinkler output
n + r = 55 . . . . . . . . . sum of two output rates
The second equation tells us we can substitute n = 55 -r into the first equation:
15(55 -r) +25r = 1175
10r = 1175 -825 . . . . . . subtract 825
r = 350/10 = 35 . . . . . . divide by 10
n - 55 -35 = 20 . . . . . . find n from r
Nguyen family's sprinkler: 20 L per hour
Reed family's sprinkler: 35 L per hour
4.1 ≈ 4 inches (tenth place is less than 5, round down)
5.9 ≈ 6 inches (tenth place is more than 5, round up)
7.2 ≈ 7 inches (tenth place is less than 5, round down)
Volume = 4 x 6 x 7
Volume = 168 in³ (Answer C)
