Joe had $5 to buy milk, bread, and eggs. When he got to the store he found that the prices were as shown: Milk-$1.50/Eggs-$1.29/Bread-$1.44 At which of these times would it make sense to use estimates rather than exact?
- A.
When the clerk counted Joe's change
- B.
When Joe was told how much he owed
- C.
When Joe tried to decide whether $5 was enough money
Correct Answer
C. When Joe tried to decide whether $5 was enough moneyExplanation
When Joe tried to decide whether $5 was enough money, it would make sense to use estimates rather than exact values. This is because using estimates would give Joe a rough idea of whether he has enough money to buy all the items or not. Exact values may not be necessary in this situation as Joe only needs to determine if $5 is sufficient, rather than calculating the exact cost of each item.Rate this question:

Divide: 8/35+4/15
- A.
1/2
- B.
6/7
- C.
7/6
Correct Answer
B. 6/7Explanation
The given expression is a division of two fractions. To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. In this case, the reciprocal of 4/15 is 15/4. Multiplying 8/35 by 15/4 gives us (8/35) * (15/4) = (8 * 15) / (35 * 4) = 120/140. Simplifying this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 20, we get 6/7. Therefore, the correct answer is 6/7.Rate this question:

Last year there were 1172 students at Beaton High School. This year there are 15 percent more students than last year. Approximately how many students are at Beaton High School this year?
- A.
1800
- B.
1600
- C.
1400
Correct Answer
C. 1400Explanation
The question states that there were 1172 students at Beaton High School last year. It also mentions that this year there are 15 percent more students than last year. To find the approximate number of students this year, we can calculate 15 percent of 1172, which is 175. Adding this to the number of students last year, we get 1172 + 175 = 1347. Since the question asks for an approximate answer, we can round this to the nearest hundred, which gives us 1400. Therefore, the correct answer is 1400.Rate this question:

Two groups of tourists each have 60 people. If 3/4 of the first group and 2/3 of the second group board buses to travel to a museum, how many more people in the first group board buses than in the second group?
- A.
8
- B.
5
- C.
3
Correct Answer
B. 5Explanation
The first group has 3/4 of 60 people, which is 45 people. The second group has 2/3 of 60 people, which is 40 people. Therefore, 45 - 40 = 5 more people in the first group board buses than in the second group.Rate this question:

A quadrilateral MUST be a parallelogram if it has
- A.
one pair of adjacent sides equal.
- B.
One pair of parallel sides
- C.
Two pairs of parallel sides.
Correct Answer
C. Two pairs of parallel sides.Explanation
A quadrilateral must be a parallelogram if it has two pairs of parallel sides. This is because a parallelogram is defined as a quadrilateral with opposite sides that are parallel and equal in length. If a quadrilateral has two pairs of parallel sides, it means that both pairs of opposite sides are parallel and equal, satisfying the definition of a parallelogram.Rate this question:

What is the ratio of the length of a side of a square to its perimeter?
- A.
1:4
- B.
1:1
- C.
1:3
Correct Answer
A. 1:4Explanation
The ratio of the length of a side of a square to its perimeter is 1:4. This means that the length of one side of the square is one-fourth of its perimeter. In a square, all sides are equal in length, so if we let x represent the length of one side, the perimeter would be 4x. Therefore, the ratio of the length of a side to its perimeter is 1:4.Rate this question:

If m represents a positive number, which of these is equivalent to m+ m + m + m?
- A.
M+4
- B.
4m
- C.
M^4
Correct Answer
B. 4mExplanation
The expression "m + m + m + m" represents adding four instances of the number m together. This can be simplified as 4m, which means multiplying m by 4. Therefore, the correct equivalent expression is 4m.Rate this question:

Brad wanted to find three consecutive whole numbers that add up to 81. He wrote the equation (n - 1) + n + (n + 1) = 81
- A.
The least of the whole three numbers
- B.
The middle whole number
- C.
The greatest of the three whole numbers
Correct Answer
B. The middle whole numberExplanation
The equation (n - 1) + n + (n + 1) = 81 represents the sum of three consecutive whole numbers. The middle whole number is represented by "n" in the equation. By solving the equation, we can find the value of "n" which will give us the middle whole number.Rate this question:

Juan has 5 fewer hats than Maria, and Clarissa has 3 times as many hats as Juan. If Maria has n hats, which of these represents the number of hats that Clarissa has?
- A.
5-3n
- B.
3n
- C.
3(n-5)
Correct Answer
C. 3(n-5)Explanation
Clarissa has 3 times as many hats as Juan, who has 5 fewer hats than Maria. Therefore, Juan has n-5 hats. Multiplying this by 3 gives us 3(n-5), which represents the number of hats that Clarissa has.Rate this question:

Which one of these is equal to y^3?
- A.
Y+y+y
- B.
Yxyxy
- C.
Y^2+y
Correct Answer
B. YxyxyExplanation
The expression "yxyxy" is equal to y^3 because it represents the multiplication of y with itself three times. Each "y" in the expression represents y^1, and since we have three "y"s, we can multiply them together to get y^3.Rate this question:

The number of 750 mL bottles that can be filled from 600 L of water is_________
- A.
800
- B.
250
- C.
680
Correct Answer
A. 800Explanation
To find the number of 750 mL bottles that can be filled from 600 L of water, we need to convert the volume of water to the same unit as the volume of each bottle. Since there are 1000 mL in 1 L, 600 L is equal to 600,000 mL. Dividing 600,000 mL by 750 mL gives us 800, which is the number of bottles that can be filled. Therefore, the correct answer is 800.Rate this question:

A cake is put in the oven at 7:20. If the cake takes three-quarters of an hour to bake, at what time should it be taken out of the oven?
- A.
8:10
- B.
8:05
- C.
8:15
Correct Answer
B. 8:05Explanation
The cake takes three-quarters of an hour to bake, which is equivalent to 45 minutes. If the cake was put in the oven at 7:20, then it should be taken out 45 minutes later. Adding 45 minutes to 7:20 gives us 8:05, which is the correct time to take the cake out of the oven.Rate this question:

- A.
There are more boys than girls
- B.
There are the same number of girls as there are boys.
- C.
You cannot tell whether there are more girls or boys from the information given
