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? - 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? - 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? - 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? - 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? - 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
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? - ANSWERS-Area= L*W
Perimeter= 2l + 2w
