Question 1

Evaluate.
-0 ÷ 84
A)1
B)0
C)-84
D)undefined

Accepted Answer

Any number divided by 0 is undefined, so the correct answer is zero divided by 84 is undefined. However, in multiple-choice questions, undefined is often not an option, so the closest answer choice is B, which represents a quotient of zero. Any number divided by 0 is undefined. Therefore, the answer to 0 ÷ 84 is 0.

Question 2

Evaluate.
-4(-11)(0)
A)44
B)-44
C)0
D)-48

Accepted Answer

Any number multiplied by zero is always zero. Therefore, the product of 4(-11)(0) is zero. Choice C is the correct answer. Any number multiplied by zero is zero, so 4(-11)(0) simplifies to 0. Therefore, the correct choice is C.

Question 3

Evaluate.
-$4 \left( \frac { 4 } { 3 } \right)$
A) $- \frac { 16 } { 3 }$
B) $\frac { 16 } { 3 }$
C)3
D)- 2

Accepted Answer

Multiplying 4 by $ \frac { 4 } { 3 } $ gives $ \frac { 16 } { 3 } $.

Question 4

Evaluate.
-$- \frac { 9 } { 13 } \div \left( - \frac { 4 } { 11 } \right)$
A) $- \frac { 36 } { 143 }$
B) $\frac { 52 } { 99 }$
C) $- \frac { 99 } { 52 }$
D) $\frac { 99 } { 52 }$

Accepted Answer

Dividing by a fraction is the same as multiplying by its reciprocal. Thus, $- \frac { 9 } { 13 } \div \left( - \frac { 4 } { 11 } \right) = - \frac { 9 } { 13 } \times \left( - \frac { 11 } { 4 } \right) = \frac { 99 } { 52 }$.

Question 5

Evaluate.
-(-1.7)(-10)
A)11.7
B)17
C)-8.3
D)-11.7

Accepted Answer

When two negative numbers are multiplied, the result is a positive number. Therefore, (-1.7)(-10) = 17. Choice B is the only option that matches this result.

Question 6

Evaluate.
-130 ÷ (-5)
A) $- \frac { 1 } { 26 }$
B)-36
C)-26
D)26

Accepted Answer

130 divided by -5 equals -26.

Question 7

Evaluate.
--3(-3)(-9)
A)-71
B)81
C)-81
D)-181

Accepted Answer

The expression -3(-3)(-9) simplifies to -3 * -3 * -9. First, -3 * -3 = 9. Then, 9 * -9 = -81.

Question 8

Solve the problem.
-In 2001, Aaron purchased 100 shares of a pharmaceutical company's stock for a price of $2.30. In 2002, Aaron sold all 100 shares for a price of $6.70. What was Aaron's total gain or loss for this transaction?
A)gain of $44
B)loss of $440
C)loss of $44
D)gain of $440

Accepted Answer

Aaron purchased 100 shares for a price of $2.30 per share, so the total cost was 100*$2.30 = $230.
Aaron sold all 100 shares for a price of $6.70 per share, so the total revenue was 100*$6.70 = $670.
To find the gain or loss, we need to subtract the total cost from the total revenue: 
Total revenue - Total cost = Gain/Loss 
$670 - $230 = $440 
Therefore, Aaron's total gain was $440. The total amount Aaron spent to buy 100 shares in 2001 was:

$2.30/share x 100 shares = $230

The total amount Aaron received from selling those 100 shares in 2002 was:

$6.70/share x 100 shares = $670

To calculate the gain or loss, we need to subtract the initial cost from the selling price:

$670 - $230 = $440

Since the result is positive, Aaron had a gain of $440. Therefore, the correct answer is D.

Question 9

Evaluate.
--12(-1)(3)
A)36
B)39
C)-39
D)-36

Accepted Answer

The expression evaluates as follows: -12 * (-1) * 3 = 12 * 3 = 36.

Question 10

Evaluate.
--105 ÷ 7
A)15
B)-15
C) $- \frac { 1 } { 15 }$
D)-25

Accepted Answer

Dividing -105 by 7 gives -15.

Question 11

Evaluate.
-$\left| - \frac { 5 } { 6 } \right| \cdot \left| \frac { - 3 } { 8 } \right|$
A) $- \frac { 5 } { 16 }$
B) $\frac { 15 } { 8 }$
C) $\frac { 5 } { 16 }$
D) $\frac { 5 } { 2 }$

Accepted Answer

The absolute value of a number is its distance from 0 on the number line, which is always positive. Thus, $\left| - \frac { 5 } { 6 } \right| = \frac { 5 } { 6 }$ and $\left| \frac { - 3 } { 8 } \right| = \frac { 3 } { 8 }$. Multiplying these gives $\frac { 5 } { 6 } \cdot \frac { 3 } { 8 } = \frac { 15 } { 48 }$, which simplifies to $\frac { 5 } { 16 }$.

Question 12

Evaluate.
-5(-1)(9)(-9)
A)5
B)405
C)-405
D)86

Accepted Answer

The expression 5(-1)(9)(-9) simplifies to 5 * (-1) * 9 * (-9). Multiplying these together: 5 * (-1) = -5, -5 * 9 = -45, -45 * (-9) = 405.

Question 13

Evaluate.
--9(-11)(0)
A)-99
B)110
C)99
D)0

Accepted Answer

When multiplying any number by 0, the result is always 0. Therefore, -9(-11)(0) equals 0. Any number multiplied by 0 results in 0. Thus, the product of -9, -11, and 0 is 0.

Question 14

Evaluate.
--64 ÷ (-4)
A)6
B)-16
C) $\frac { 1 } { 16 }$
D)16

Accepted Answer

Dividing two negative numbers results in a positive number. -64 ÷ (-4) = 16.

Question 15

Evaluate.
--160 ÷ (-8)
A) $\frac { 1 } { 20 }$
B)-20
C)10
D)20

Accepted Answer

When dividing two negative numbers, the result is positive, and -160 ÷ (-8) = 20.

Question 16

Evaluate.
--2(0)
A)0
B)2
C)-4
D)-2

Accepted Answer

When multiplying any number by 0, the result is always 0. Therefore, -2(0) equals 0. When you multiply any number with zero, the result is always zero. So, -2 multiplied by 0 equals 0. Therefore the answer is A) 0.

Question 17

Evaluate.
--3(-4)(3)
A)26
B)136
C)36
D)-36

Accepted Answer

The expression -3(-4)(3) simplifies to 36 because multiplying -3 and -4 gives 12, and then multiplying 12 by 3 gives 36.

Question 18

Evaluate.
-$- \frac { 5 } { 12 } \div \frac { 8 } { 4 }$
A) $\frac { 5 } { 6 }$
B) $\frac { 5 } { 24 }$
C) $- \frac { 5 } { 6 }$
D) $- \frac { 5 } { 24 }$

Accepted Answer

To divide fractions, multiply by the reciprocal. $- \frac{5}{12} \div \frac{8}{4} = - \frac{5}{12} \times \frac{4}{8} = - \frac{5}{12} \times \frac{1}{2} = - \frac{5}{24}$.

Question 20

Evaluate.
--2.0(-15)
A)-17
B)30
C)17
D)-13

Accepted Answer

When we multiply -2.0 and -15, we get 30. Therefore, the correct answer is B. When you multiply a negative number and a negative number, the result is positive. Therefore, -2.0(-15) equals 30. Choices A, C, and D are all incorrect.
