If a square box has a volume of 27 in3in3 what's the perimeter of each side of the box? A)6 inches B)12 inches C)9 inches D)15 inches

SOLUTION A square box is a cube which means that length = width = height. Volume for a cubic box is the length of one side of the box cubed or V = s3s3 where s is the length of one side of the box. The cube root of 27 is 3 so the size of each side of the box is 3. The perimeter of a box is 2w + 2h which, in our case, is: (2 inches x 3) + (2 inches x 3) = 6 inches + 6 inches = 12 inches

If a square box has a volume of 8 in3in3 what's the perimeter of each side of the box? A)4 inches B)10 inches C)8 inches D)6 inches

SOLUTION A square box is a cube which means that length = width = height. Volume for a cubic box is the length of one side of the box cubed or V = s3s3 where s is the length of one side of the box. The cube root of 8 is 2 so the size of each side of the box is 2. The perimeter of a box is 2w + 2h which, in our case, is: (2 inches x 2) + (2 inches x 2) = 4 inches + 4 inches = 8 inches

20 is 14% of what number? A)142.86 B)280 C)14.29 D)2.80

SOLUTION First, create an equation using the variable nn to represent the number that we're looking for: 20 is 14% of nn which translates to 20=14%×n20=14%×n. Converting 14% to a decimal by dividing it by 100 gives us the equation 20=0.14n20=0.14n and solving for n by dividing both sides by 0.14 gives us the answer 142.86. NOTE You know that 20 is 10% of 200. Because 14% is larger than 10% you know that the answer to this question has to be smaller than 200 but approximately the same magnitude. Knowing this you may be able to cross off a couple of possible answers (or even identify the correct answer) right from the start

What's the circumference of a circle that has a radius of 6? A)9.42 B)177.65 C)75.40 D)37.70

SOLUTION The factorial of a number is the product of all positive integers less than or equal to the number. So, the factorial of 7 is 1×2×3×4×5×6×71×2×3×4×5×6×7 which is 5,040

Connie loaned Sam $1,000 at a yearly interest rate of 5%. After one year what is the interest owed on this loan? A)$50 B)$1,050 C)$60 D)$5

SOLUTION The yearly interest charged on this loan is the annual interest rate (5%) multiplied by the amount borrowed ($1,000). To get the interest charged first convert the interest rate from a percentage to a decimal by dividing by 100 (5 / 100) to get 0.05 then multiply 0.05 by $1,000 to get $50 NOTE When you're dealing with percentages you'll always need to convert the percent to a decimal by dividing by 100 before doing any calculations with it.

Eight girls in a club are comparing their weekly allowance. Jan and Sue each receive $10 a week. Lori and Tina each receive $5 a week. Julie, Christie and Faith each receive $12 a week. Cheryl does not get an allowance but her parents often buy her things as she needs them. What is the average amount of allowance given among these 8 girls? A)$8.25 B)$7.00 C)$9.42 C)$6.75

The average is solved by adding all of the values given and dividing the total by the number of values: Average =(10+10+5+5+12+12+12+0)8=668=8.25(10+10+5+5+12+12+12+0)8=668=8.25 Average allowance = $8.25

Your new remodel is almost done. The contractor needs to put the final framing on and needs 8 sections, measuring 4 feet, 2 inches each. The framing is available from the supplier by 10-foot lengths only. What is the total length of the lumber that needs to be purchased? A)48 feet B)34 feet C)30 feet D)40 feet

The contractor needs 8 pieces of 4-foot, 2 inch framing. A 10-foot lumber can be made into two pieces of framing. In order to complete the 8 pieces needed, the contractor needs to order 4 pieces of 10-foot long lumber. So, 4 pieces x 10 feet = 40 feet of framing The contractor actually only needs a total of 34 feet of framing, but lumber is usually cut and sold in even lengths by feet (such as 10, 12, 14 and 16 feet). And as stated in this question, the lumber availability was in 10-foot length

You work in a hospital and make $15.28 per hour for a 40 hour a week. If you work the night shift you get a slight differential added at $2.32 per hour worked during this shift. You just completed your first week and worked 34 hours on a regular shift and 6 hours on the night shift. What is the total amount you earned this week? A)$519.52 B)$615.20 C)$625.12 D)$611.20

The correct answer is: $625.12 Explanation: The total amount earned is computed by adding the amount earned for the day shift and the amount earned for the night shift. Amount earned for the day shift = 34 x 15.28 = $519.52 Amount earned for the night shift = 6 x (15.28 + 2.32) = 6 x 17.6 = $105.60 The total amount earned for the week = $519.52 + $105.60 = $625.12
