So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27
To find the number of questions in the exam, make an equation
(90% =
= 0.9)
= 
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.

- The required function formula for the function "f" is
- Since the side length of the square cannot be positive, hence the domain will be values from 0 and above i.e. Domain = 0≤x≤∞
- The range of the function will be 4≤f(x)≤∞
The perimeter of a square is expressed according to the formula:
P = 4L
P is the perimeter of the square
L is the side length of the square
Given the following
Perimeter is y
Length is x
The function that represents the statement is expressed as
The required function formula for the function "f" is
The domain of the function is the value of the input value for which the function exists
- Since the side length of the square cannot be positive, hence the domain will be values from 0 and above i.e. Domain = 0≤x≤∞
The range of the function is the value of the output value f(x) for which the function exists, hence;
- The range of the function will be 4≤f(x)≤∞
