Janet makes homemade dolls. Currently, she produces 23 dolls per month. If she increased
her production by 18%, how many dolls would Janet produce each month? correct answers
First, calculate 18% of 23.
23 × 0.18 = 4.14
Then, add this value (the increase) to the original value of 23.
23 + 4.14 = 27.14
Rounding off, we get 27.
What is the formula for Area? correct answers Area = L*W
Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is
two times the width, what is the perimeter of the porch? correct answers The formula for the
area of a rectangle:
A = Width * Length
From the question we know that L = 2W and that A = 50. So we can plug these values into
our equation and solve for W:
50 = W * L
50 = W * 2W
50 = 2W²
W² = 25
W=5
We know that L = 2W, so L = 10
Perimeter = 2L + 2W
Perimeter = 2 * 10 + 2 * 5
Perimeter = 30
Diego's current age is five times Martina's age ten years ago. If Martina is currently m years
old, what is Diego's current age in terms of m? correct answers Martina's age ten years ago is:
m − 10
So Diego's age is:
5(m − 10)
= 5m − 50
The variables x and y are directly proportional, and y = 2 when x = 3. What is the value of y
when x = 9? correct answers Y= K*X
2= K*3
2/3 = K*3 /3
K = 2/3
Plug in K for the second formula
Y=2/3(9)
Y = 2*3 = 6
