81/4 is the answer , use formula (b/2) squared
<u>Answer</u>
40%
<u>Explanation</u>
A parentage value is a value that has been compared to 100.
Percentage = (change in the value)/(the original value) × 100%
= (35-25)/25 × 100%
= 10/25 × 100%
= 40%
The answer is 1/2n-4
Multiplying a number n by 1/2 is the same as dividing that number by 2.
First, subtract to get the difference.
2.85 – 2.78 = 0.07
Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).
Hope this helps!
