This means that we can form the equation , since the amount of water remaining is proportionate to the amount of weeks that have passed.
We know , since we need to find the change for 8 weeks.
The change will be the absolute value of -40, which just makes it positive, so 40.

<u>Given</u>:
Given that the side of the regular polygon is 16 feet.
We need to determine the area of the polygon.
<u>Area of the polygon:</u>
The area of the polygon can be determined using the formula,
where n is the number of sides,
s is the side length.
Substituting n = 3 and s = 16, we get;
Simplifying, we get;
Dividing, we get;
Rounding off to the nearest tenth, we have;
Thus, the area of the regular polygon is 110.9 square units.
Answer:
Step 2
18 over 8 to a decimal is 2.25
Step-by-step explanation:
Step 1, 20, subtract 16 labeled as
Step 2, 40 labeled as
Step 3, subtract 40, and 0 labeled as Step 4.
Divisor = 8
Divided = 18
Quotient = 2.25
2.25
8 √18
- 16
2 0
- 16
4 0
- 40
0
The first error is at step 2
18 over 8 to a decimal is 2.25
