We know the equation will be 3(2)^t, so now we need to find the amount of months it will take.
3(2)^9 = 1536
3(2)^11 = 6144
The correct answer is D.
There are 24 (2x8+2x4) posts around the pool with 4 overlaps, therefore, there are 20 posts in total.
Among the 8 posts along one side, there are 7 gaps in between them. Hence, the length is 2x7=14yards
Among the 4 posts on the other side, there are 3 gaps in between them. Hence, the width is 2x3=6 yards
Answer:

Explanation:
The sum of two numbers is the result of when they are added up. So the "sum of the length and width" is the length + width or l + w. One-sixth of the sum of the length and width is l+w divided by 6. so you get:

Hope this helps!
The answer would be 0.05 because the five is in the hundredths place
