Terri has a jar of orange, blue, green, and red chocolate candies. In the jar are 75
orange candies, 62 blue candies, and 52 green candies. If there is a total of 252
candies in the jar, what is the probability that Terri will pick a red candy? - ANSWER -
To solve this problem, first find the number of red candies in the jar by adding the
numbers of all the other candies together, then subtracting from the total. 75 orange +
62 blue + 52 green = 189 candies 252 - 189 = 63 red candies
Probability is the chance that a certain event will happen. Since there are 63 red
candies out of a total of 250 candies, divide 63 by 252. Reduce the fraction by dividing
the numerator and denominator by 63. 63/252 ÷ 63/63 = ¼
A mobile classroom is a rectangular block that is 100 feet by 20 feet in length and width
respectively. If a student walks around the block once, how many yards does the
student cover? - ANSWER - Perimeter is equal to two times the length added to two
times the width, or 2L + 2W. The total distance traveled around the block is the
perimeter, which is 2(length) + 2(width).
2(100) + 2(20) = 200 + 40 = 240 feet
Set up a proportion to convert feet to yards. 1 yard = 3 feet x yards = 240 feet 1/3 =
x/240 240 = 3x x = 80 yards
Will is filling up his pool for the summer, and water from the hose flows into the pool at 6
gallons per minute. The pool holds 17,280 gallons. How long, in hours, does it take to fill
the pool? - ANSWER - The water is flowing into the pool at a rate of 6 gallons per
minute. Do the math to see how long it takes to get to 17,280 gallons: 17,280 gallons ÷
6 gallons/minute = 2,880 minutes To convert to hours, divide by 60 minutes: 2,880
minutes ÷ 60 minutes/hour = 48 hours

What is 85,000,000,000 in scientific notation?
8.5 x 10^10
8.5 x 10^-10
.85 x 10^11
85 x 10^9 - ANSWER - In scientific notation, move the decimal point so it rests after the
first number (8). The exponent attached to the 10 expresses the number of decimal
points that must be added to the base number (8.5) in order to correctly write the
number.
At the arcade, Nick spent 203 tokens on videogames in seven days. Each day he spent
five more tokens than the previous day. How many tokens did Nick spend on the third
day at the arcade?
14 tokens
24 tokens
29 tokens
34 tokens - ANSWER - Let x = the number of tokens Nick spent on day 1. Set up the
following equation and solve for x:
x + (x + 5) + (x + 10) + (x + 15) + (x + 20) + (x + 25) + (x + 30) = 203
7x + 105 = 203
x = 14 tokens
We know Nick spent 14 tokens on the first day. To find what he spent on the third day,
add 10 tokens to get 24 tokens
Continue the pattern: 6, 9, 13.5, 20.25..., ?
a. 32.5
b. 25
c. 30.375
d. 27 - ANSWER - The pattern is the previous number multiplied by 1.5. Therefore, 6 ×
1.5 = 9; 9 × 1.5 = 13.5; 13.5 × 1.5 = 20.25; and 20.25 × 1.5 = 30.375.
Kevin and Kara are in a pancake-eating contest. Kevin can eat three pancakes per
minute, while Kara can eat 3 ½ pancakes per minute. How many total pancakes can
they eat in 10 minutes?
52 pancakes
72 pancakes
65 pancakes
44 pancakes - ANSWER - If Kevin eats 3 pancakes in one minute, you know he eats
3(10) = 30 in 10 minutes. If Kara eats 3 ½ per minute, she eats 3.5(10) = 35 in 10
minutes. Add 30 + 35 = 65 and you have your answer.

Jenny's test grades are 93,89, 96, and 98. If she wishes to raise her average to 95,
what does she need to score on her next test?
(a) 100
(b) 99
(c) 97
(d) 95 - ANSWER - B. x = the unknown score. (93 + 89 + 96 + 98 + x) ÷ 5 or (376 + x) ÷

376 + x = 95(5)
376 + x = 475
-376
x= 99
