In t minutes, t/20 of the pool is filled and t/30 of it is emptied.
t/20 - t/30 = 1
multiply both sides by LCM 60.
3t - 2t = 60
t = 60
The pool is filled in 60 minutes.
What are the measurements?
Option 1 is better. 12% of $300 is $36, so even in just the first year, it grows by $6 more than if they picked the other option. I hope this helps :)
Answer:
Step-by-step explanation:
(9x^6)^-1/2
=1/(9x^6)^1/2
=1/9^1/2 • x^3
=(3^2)^1/2 • x^3
=1/3x^3
