Answer:
C, √45
Step-by-step explanation:
First, we can use process of elimination to get rid of A and D, since we know we're looking for a range, and only the highest or the lowest number is going to be outside of that range.
Now we simply have to run the remaining answers through our calculators. √62 is 7.87 and √45 is 6.71. Since 7.87 is between 7 and 8 and 6.71 is not, C must be our answer.
Answer:
r^11

Answer:i explained it
Step-by-step explanation:
The total cost of the fence will be 30(2L + 2W) + 2*25 W <= 9000
60L + 110W <= 9000
60 L <= 9000 - 110W
L <= 150 - 11/6 W
For a given width, the maximum area will correspond to the maximum length, so we can just go ahead and say L = 150 - 11/6 W
A = LW = (150 - 11/6 W) W
A = 150 W - 11/6 W2
A' = 150 - 11/3 W = 0
150 = 11/3 W
W = 450/11
