3) Which answer is the opposite of the quotient of 48 and 3?

-2(5+4)

12 + (-28)

42 / -2

12 * 12

The given expression "12 + (-28)" is the opposite of the quotient of 48 and 3. The quotient of 48 and 3 is 16, and the opposite of 16 is -16. Therefore, the expression "12 + (-28)" is the opposite of the quotient of 48 and 3.

Explanation

The given expression "12 + (-28)" is the opposite of the quotient of 48 and 3. The quotient of 48 and 3 is 16, and the opposite of 16 is -16. Therefore, the expression "12 + (-28)" is the opposite of the quotient of 48 and 3.

4) The associative property of addition says that you can "change the groupings" of numbers in addition, but the answer will be the same. For example (4 + 5) + 6 = 4 + (5 + 6). Which example shows the associative property of multiplication? (* is the symbol for multiplication).

8 * 7 = 7 * 8

2 * 4 * 6 = 4 * 6 * 2

(9 + 8) + 7 = 9 + (8 + 7)

(5 * 6) * 7 = 7 * (6 * 5)

The answer has to be C, D, or E, because they are the only three with ( ... ) Answer C is addition, so it cannot be the answer. Look closely at answer D. The (group) does not change, they are still 5 and 6.

Explanation

The answer has to be C, D, or E, because they are the only three with ( ... ) Answer C is addition, so it cannot be the answer. Look closely at answer D. The (group) does not change, they are still 5 and 6.

6) An elevator starts empty on the fifth floor. Three people get on and go to the tenth floor. Two more people get on and everyone travels to the 13th floor, where four people get off. Two more people get on and everyone travels to the 18th floor. Five more people get on and the elevator goes down to the 2nd floor. Three more people get on and go down four floors to the basement. How many floors did the elevator travel from start to finish?

8) 25% of all Monsters are Ogres. 50% of Ogres are Ughrhats. In a population of 80 Monsters how many would be Ughrhats?

10

60

75

44

If the total population is 80, then 25% of 80 = 20 Ogres. Of those 20 Ogres, 50% of them are Ughrhats, so 50% of 20 is ten.

Explanation

If the total population is 80, then 25% of 80 = 20 Ogres. Of those 20 Ogres, 50% of them are Ughrhats, so 50% of 20 is ten.

9) IF 21 x 34 is 714, then 0.21 x 3.4 is ...

.0714

714,000

.714

The answer is .714 because when you multiply 21 by 34, you get 714. To find the product of 0.21 and 3.4, you can move the decimal point two places to the left in both numbers, resulting in .21 and 3.4. When you multiply these two numbers, you get .714.

11) Which statement or statements below is/are false?

(8 - 3)(6) = 30

49 / 7 = (3 * 4 + 2) / 2

-2 x 5 x -9 = -90

8 + 4 + 9 + (-8) = 13

The statement "-2 x 5 x -9 = -90" is true because when multiplying two negative numbers, the result is positive. In this case, -2 x -9 = 18, and then multiplying 18 by 5 results in -90.

{21, 25, 43}

{23, 39, 47}

{29, 31, 43}

The set {29, 31, 43} has only prime numbers because all three numbers in the set, 29, 31, and 43, have only two factors, 1 and themselves. Therefore, they meet the definition of prime numbers.

13) Factors are those number that when multiplied together give you a product. For example, 4 and 8 are factors of 32:: 8 and 2 are factors of 16. Which statement does not show the same relationship.

12 and 4 are factors of 48

8 and 13 are factors of 104

14 and 5 factors of 70

18 and 3 are factors of 64

The correct answer is 18 and 3 are factors of 64. This statement does not show the same relationship because 18 and 3 do not multiply together to give a product of 64.

Explanation

The correct answer is 18 and 3 are factors of 64. This statement does not show the same relationship because 18 and 3 do not multiply together to give a product of 64.

14) Imagine that there is a test with 20 questions. Each question is worth the same percent value as every other question. Therefore, each question is worth _____ of your grade.

20%

10%

5%

2%

Each question is worth 5% of your grade because there are 20 questions in total and each question is worth the same percent value as every other question. So, if we divide 100% (the total possible grade) by 20 (the number of questions), we get 5%.
