Answer 32

C. -82.50

Answer 33

+. $3

Answer 34

0 (there is no change).

Answer 35

+$3 (the account balance increases by $3).

Answer 36

The best representation of a charge of 0 is either "no change" or "+$0" because there is no change in the account balance. This could also be represented as "-$0", but typically charges are represented as negative numbers and a negative charge would be a decrease in the account balance.

B. 48.

Explanation:

4a + b = 4(7) + 5

= 28 + 5

= 33

Answer 49

C. 5

Explanation:

We can solve the equation 6x = 30 for x by dividing both sides by 6:

6x/6 = 30/6

x = 5

Therefore, x = 5 makes the equation 6x = 30 true.

Answer 50

A. -$136

Answer 51

46 with a remainder of 20

Explanation:

When we divide 1,012 by 22 using long division, we get:

```
46
-------
22 | 1,012
88 |__
-------
202
198 |__
-------
4

```
Therefore, 1,012 divided by 22 is equal to 46 with a remainder of 4. The final answer can be expressed as a mixed number or as a decimal (46.1818...).

Answer 52

C. > (greater than)

Answer 53

A. Mode

Answer 54

126.9

Answer 55

Using proportion:

3 boxes / 7 minutes = x boxes / 35 minutes

Cross-multiplying:

7 minutes * x boxes = 3 boxes * 35 minutes

7x = 105

Dividing both sides by 7:

x = 15

Therefore, the packing operator can assemble 15 cardboard boxes in 35 minutes.

Answer 56

A. 45 sq in

Explanation:

The area of a parallelogram is given by the formula:

Area = base x height

In this case, the base is the length of the side given by n, and the height is the distance from n to the opposite side, which is given by m.

Therefore:

Area = n x m

Area = 4 in x 5 in

Area = 20 sq in

However, since the angle between sides n and m is not 90 degrees, the height of the parallelogram is not given by side p. Instead, we can use the Pythagorean theorem to find the height h:

h^2 = p^2 - n^2

h^2 = 9^2 - 4^2

h^2 = 65

h ≈ 8.06 in

Therefore:

Area = n x h

Area = 4 in x 8.06 in

Area ≈ 32.24 sq in

However, we must note that this is not one of the answer choices. Therefore, we assume that the closest answer choice is A, which is 45 sq in.

Answer 57

The ratio of students selected to those trying out is:

6:12

which can be simplified by dividing both sides by the greatest common factor, which is 6:

6:12 = 1:2

Therefore, the ratio of students selected to those trying out is 1:2.

Answer 58

C. Pages Read per Day: 50, 65, 90, 100, 110, 110, 125, 130, 140.

Answer 59

x = 36

Explanation:

To solve for x, we need to get it by itself on one side of the equation.

We can do this by subtracting 73 from both sides of the equal sign:

x + 73 - 73 = 109 - 73

Simplifying:

x = 36

Therefore, x is equal to 36.
