The answer of the question is x.
Answer:
A is correct.
Step-by-step explanation:
Here, the x would represent the gallons per minute. The minutes are unknown, so it's just a variable. It can't be B either, because the addition sign would mean that the pool is being filled instead of drained.
The mean is the average so 180/50 = 3.6 therefor the mean of each donation from each sponsor is £3.60
(-2,3) to (2,-3)
6^2 + 4^2 = c^2
c = 7.21
————
(-2,3) to (1,5)
2^2 + 3^2 = c^2
c = 3.61
————
3.61 * 7.21 = approx. 26.03
The area is 26.03un^2
The common denominator would be 18. So, 5/6 becomes 15/18 and 7/9 becomes 14/18
