Answer:
a = A/πb
Step-by-step explanation:
To solve this subject of the formulae given that A = πab.
<u>solution</u>
A = πab
the next step is to look for a unique way to get rid of the variables disturbing "a" from standing alone. this variables are π and b, we need to detach dem from a
A = πab
divide both sides by πb
A/πb = πab/πb
A/πb = a
a = A/πb
therefore the value of a in the fomular A = πab is evaluated to be a = A/πb
The approximate percent increase in the average grade is 21.43%.
<h3>
What is the percentage increase?</h3>
Percentage is a measure of frequency that expresses a number as a value out of hundred. The sign used to denote percentage is%.
Percentage increase = (new grade / initial grade) - 1
(85 / 70) - 1 = 0.2143 = 21.43%
