Answers & Explanations
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.
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, 2l + 2w = 132. Substituting 36 for l gives 2(36) + 2w = 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.
The volume of a cylinder is represented by the equation, V=πr2 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.
The volume of a cube is represented by the equation, V=s3, where s represents one side length. Substituting 5 for s gives V=53, or V = 125. The volume of the cube is 125 cubic inches.
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.
The volume of a cylinder is represented by the equation, V=πr2h, 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.
The area of a square is represented by the formula, A=s2. Substituting 16 for A gives: 16=s2. 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.
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.
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.
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 0.9WL.
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.
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”.
The number of mg left is equal to the difference of 500 mg and 325 mg, or 175 mg.
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.
The product of these dimensions is 1,680 ft” (14 ft x 20 ft x 6 ft), thus this aquarium meets the required volume.
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.
