If a square box has a volume of 125 in3in3 what's the perimeter of each side of the box?
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 125 is 5 so the size of each side of the box is 5. The perimeter of a box is 2w + 2h which, in our case, is: (2 inches x 5) + (2 inches x 5) = 10 inches + 10 inches = 20 inches

Cory's average score after 8 tests is 91%. If he gets a 78% on his 9th test, what will his new average be?
For the 8 tests, the average is presented as 91, so you can assign the value of 91 to each of the 8 previous scores. This gives us 8 tests with a score of 91 each. 91⋅8=728 91⋅8=728 To get new average after the 9th test, use the same formula: 728+789=8069=89.5 728+789=8069=89.5 Since there are 2 answer choices that are very close to this, and you don't know which way the .5 will be rounded, extend the division another place by adding a 00 to the dividend, then divide. You find that the answer is now 89.5589.55, which rounds up to 89.689.6. Therefore, you now know that 89.589.5 would not be correct. Always extend the decimal places when 2 answer choices are as close as these and you don't know which one is correct. 89.6%

There are two pizza ovens in a restaurant. Oven 1 burns three times as many pizzas as oven 2. If the restaurant had a total of 12 burnt pizzas on Saturday, how many pizzas did oven 2 burn?
The correct answer is (A). Begin by setting up a system of equations to represent the situation, letting x represent oven 1 and y represent oven 2. x = 3y and x + y = 12 Substituting the first equation into the second: 3y + y = 12 so y = 3.
The hour hand of a watch rotates 30 degrees every hour. How many complete rotations does the hour hand make in 6 days?
The correct answer is (C). There are 360 degrees in a complete circle, so 360/30 = 12 hours to make one full circle. In 6 days there are 24 hours x 6 = 144 hours total. The total number of rotations will be 144/12 = 12.
If a store adds 50 chairs to its current inventory, the total number of chairs will be the same as three-halves the current inventory of chairs. If the manager wants to increase the current inventory by 40%, what will the new inventory of chairs be?
The correct answer is (D). This word problem requires careful translation. Let's say t = total current inventory of chairs. The first sentence states that 50 + t = (3/2)t. First solve for the current inventory: 50 + t = (3/2)t 50 = (3/2)t − t 50 = (1/2)t 100 = t The manager wants to increase this by 40%. 40% of 100 is 40, so the new inventory will be 140.

Julie gives 7 pieces of candy to each of her friends. If Julie gives all of her candy away, which amount of candy could have been the amount she distributed?
The problem states that all of Julie's friends received 7 pieces each. There is no mention about the number of friends Julie gave the candies to. But no matter how many friends Julie gave the candies to, the total number of candies she has given away must be divisible by 7. There is no other way to solve the problem but try each given choice and pick one that is divisible by 7 and results in a whole number. 1617=23 1617=23 1287=18.28 1287=18.28 1457=20.71 1457=20.71 1627=23.14 1627=23.14 Therefore, the answer is 161 candies (distributed to 23 friends with 7 candies each).

Trapezoid question
The trapezoid consists of two smaller shapes: a triangle and a rectangle. Draw a line from point A across this figure to form the two shapes. Find the area of each shape and then add them together to find the area of the trapezoid. Area of rectangle = length x width. Therefore, the area of the rectangle is 18x20 = 360 Area of a triangle = 1/2(base)(height). The base of the triangle is 20. The height of the triangle is unknown. Use the Pythagorean Theorem to find the triangle's height. c2 = a2 + b2 where c is the triangle's hypotenuse. 292 = 202 + (height)2 841 = 400 + (height)2 441 = (height)2 The square root of 441 is 21 height = 21. Therefore, area of the triangle = (1/2)(20)(21) = 210. The total area of the trapezoid = 360+210 = 570.

Each year, a cyber café charges its customers a base rate of $25, with an additional $0.30 per visit for the first 50 visits, and $0.10 for every visit after that. How much does the cyber café charge a customer for a year in which 72 visits are made?
Translate the information into arithmetic. The café charges $25 + $0.30(first 50) + $0.10(additional after 50). For 72 visits there are 50 visits with an additional 22 visits. $25 + $0.30(50) + $0.10(22) =$25 +$15 + $2.20 =$42.20
