Answer:
I believe it would be 4/6
Step-by-step explanation:
You have four different ways to get a sum of 7: 1 and 6; 2 and 5; 3 and 4; or 4 and 3.
You would have about 3472 Hours
.18\8=1.44 for 8 hour
5000/1.44=3472
Hope this helps :)
So when X is 0, the area of the pool is 1200. That makes A and C impossible... then you can plug in numbers...say the boardwalk is 1 ft wide, add 2 to each dimension and plug in 1 for X. (You're adding 2 because there is a tile on either side of each dimension, including corners).
32x42=1344=4+140+1200
Therefore the answer is B.
