Let total number of questions be x.
According to the question,
80% of x is 32
or 80/100 × x = 32
or x = 32 ÷ 80/100
or x = 32 × 100/80
or x = 32 × 10/8
or x = 4 × 10
or x = 40
<em>So</em><em>,</em><em> </em><em>total</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>que</em><em>stions</em><em> </em><em>is</em><em> </em><em>4</em><em>0</em><em>.</em>

Answer: x = 9</h3>
=========================================
The diagram shows:
Recall that the area of a parallelogram is equal to the base times height
area = base*height
We're told that the area is 117 square units, so that means 13x = 117.
Divide both sides by 13 to isolate x
13x = 117
13x/13 = 117/13
x = 9
The height of the parallelogram is 9
Note how:
area = base*height = 13*x = 13*9 = 117
which helps confirm we have the correct height value for x.
Answer:
D. x. x^7 . x^-4
Step-by-step explanation:
A. X^5 . X^-4 .X^2=X^(5-4+2)= X^3
B. X^-2 .X^9 .x^-4=X^(-2+9-4)= X^3
C.x^0 . x^10 . x^-7=X^(0+10-7)= X^3
D. x. x^7 . x^-4=X^(1+7-4)= X^4
