TSI Math Test Preparation Questions And Answers All Correct 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? - ANS 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? - ANS 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? - ANS 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? - ANS 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
