Answer:
there is no graph
:( sorry I would answer it if it had a graph
After 6 weeks........................16,800 gallons left
10 weeks.......................5,600 gallons
this means that in 4 weeks they used 16,800-5,600=11,200 gallons
11200/4=2,800/week
5600/2800=2
10+2=12
we have 12 weeks of dry season
Answer:
6(3)-3
Step-by-step explanation:
Please write that as 60^(1/2) for greater clarity.
Our job here is to find the largest perfect square factor of 60. Note that 60 = 4*15; 4 is a perfect square, but 15 is not.
Thus, 60^(1/2) = 2sqrt(15).
