Janet makes homemade dolls. Currently, she produces 23 dolls per month. If
... [Show More] she increased her
production by 18%, how many dolls would Janet produce each month? - 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? - 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? - 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? - 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? - 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? - Area= L*W
Perimeter= 2l + 2w
L = W + 18 = 9+ 18 = 27
72 = 2 ( W+18) = 2w
72 = 2w+ 36+ 2w
72 = 4w + 36
36/4 = 4w/4 ----> 9= W
27* 9 = 243
The answer is 243
There are 20 children in the cast of a class play, and 8 of the children are boys. Of the boys, 4
have a speaking part in the play, and of the girls, 8 do not have a speaking part in the play. If a
child from the cast of the play is chosen at random, what is the probability that the child has a
speaking part? - Boys + girls = 20 8 of the children are boys + 12 girls = 20 the boys have 4
speaking parts and 4 do NOT have a speaking part. And of the girls 4 have a speaking part, but
8 of the girls do NOT have a speaking part. all of that added up should give you 20. 8 out of 20
have a speaking part, so we write that in a fraction form reduce it down which gives you the
answer: 2/5. CONTINUES...... [Show Less]
