Answer: NO. He had an increase of 25%
<u>Step-by-step explanation:</u>
To find the percentage increase, use the following formula where New (this week) = 25 and Original (last week) = 20.
Convert the decimal into percentage by moving the decimal point two places to the right. 0.25 = 25%
Evan spent 25% more time this week than last week.
It can also be stated that this week Evan did 125% of homework compared to last week.
If Even spent 125% more than last week, he would have spent 100% (20 hours) + 25% (4 hours) = 24 hours.
25 because each side is 5cm. So when you multiply length times width, you would multiply 5x5. So 25cm^2

Answer:
Step-by-step explanation:
Given:
F = ⁹/5C + 32
Required:
Solve for C
Solution:
Subtract both sides by 32
F - 32 = ⁹/5C + 32 - 32
F - 32 = 9C/5
Multiply both sides by 5
5(F - 32) = 9C/5 × 5
5(F - 32) = 9C
Divide both sides by 9
