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? 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 There are 20 children in the cast of a class play, and 8 of the children are boys.

And of the girls 4 have a speaking part, but 8 of the girl 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 [Show More]
