## Answers & Explanations

1. **A:** The area of the room is equal to the product of 10 ft and 12 ft, or 120 ft'. 120 ft' = 13.3 yd', so the total cost is equal to the product of the area of the room, or 13.3 yd' and $12.51 (the cost per square yard). It will cost $166.80 to carpet the room.

2. **A:** The perimeter of the house is equal to 132 feet, since there are 3 feet in 1 yard. The perimeter of the house may be represented by the equation, 2*l* + 2*w* = 132. Substituting 36 for l gives 2(36) + 2*w* = 132. Solving for *w* gives *w* = 30, which is measured in feet. 30 feet = 10 yards, so the width of the house is also equal to 10 yards.

3. **B:** The volume of a cylinder is represented by the equation, *V*=π*r*^{2} *h*, where *r* represents the radius and *h* represents the height. Substituting 3 for *r* and 8 for *h* gives *V*=π(3)^{2} (8), or *V* = 72π. Thus, the volume is approximately 226.2 cubic units.

4. **E:** The volume of a cube is represented by the equation, *V*=s^{3}, where s represents one side length. Substituting 5 for *s* gives *V*=5^{3}, or *V* = 125. The volume of the cube is 125 cubic inches.

5. **D:** The sum of the material is equal to 7 yd, 5 ft, 19 in, which may also be written as 7 yd, 6 ft, 7 in, or 9 ft, 7 in.

6. **B:** The volume of a cylinder is represented by the equation, *V*=π*r*^{2}*h*, where *r* represents the radius and *h* represents the height. Substituting 1.5 for *r* and 8 for *h* gives *V*=π(1.5)^{2} (8), or *V* = 18π. Thus, the volume is approximately 56.55 cubic inches.

7. **C:** The area of a square is represented by the formula, A=s^{2}. Substituting 16 for A gives: 16=*s*^{2}. Solving for *s* shows each side length to be 4 feet. Thus, the perimeter is equal to the product of 4 and 4 ft, or 16 ft.

8. **B:** Liters measure capacity and are appropriate for the size of a bathtub. Milliliters are also a measurement of capacity, but are too small a measurement for such a large container.

9. **D:** A length of 0.17 feet is equal to 2.04 inches. The following proportion may be used to determine the length, in inches: 0.17/*x*=1/12. A length of 2.1875 inches is the closest to this measurement.

10. **A:** The area may be represented as *A = WL*, measured in yards, or *A = 9WL*, measured in feet. Thus, the charge is equal to the product of *9WL* and 0.10 or 0.9*WL*.

11. **C:** The following proportion may be used to find the measurement, in centimeters: 1/2.54=76/*x*. Solving for *x* gives *x* = 193.04. The man is 193.04 cm tall.

12. **A:** The volume of a rectangular prism is equal to the product of the length, width, and height. Thus, the volume of the room may be represented as *V*=11^{.}12*.*9, which equals 1188 ft".

13. **B:** The number of mg left is equal to the difference of 500 mg and 325 mg, or 175 mg.

14. **C:** The following proportion may be used to find the number of mL to be given: 4/5=20/*x*. Solving for *x* gives *x* = 25. Thus, 25 mL need to be given.

15. **C:** The product of these dimensions is 1,680 ft" (14 ft x 20 ft x 6 ft), thus this aquarium meets the required volume.

16. **B:** The following proportion may be used to find the number of calories in 2 1/2 slices of bread: 1/80=(2 1/2)/*x*. Solving for *x* gives *x* = 200. There are 200 calories in 2 1/2 slices of bread.
