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 answer: 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 answer: 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 answer: 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 answer: 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 answer: Y=
KX 2= K3
2/3 = K3 /3 K = 2/3 Plug in K for the second formula Y=2/3(9) Y = 23 = 6
The correct answer is 6
The yard behind Cindy’s house is rectangular in shape and has a
perimeter of 72 feet. If the length L of the yard is 18 feet longer
than the width W of the yard, what is the area of the yard, in
square feet? correct answer: Area= L*W
Perimeter= 2l + 2w
