The answer is B, 38.75

Step-by-step explanation:

The mean, you add up all the numbers and divided it by how much numbers are there.

1) 20 + 22 + 25 + 31 + 33 + 34 + 41 + 41 + 45 + 50 + 56 + 67 = 465

2) Count. How many numbers are there? There are 12 numbers.

3) 465/12 is 38.75

Answer: 29

Step-by-step explanation:

[tex]58*\frac{4}{8} =\frac{58*4}{8} =\frac{232}{8} =29[/tex]

[tex]\boldsymbol{\sf{58*\dfrac{4}{8} }}[/tex]

We reduce the fraction 4/8 to its lowest expression by extracting and canceling 4.

Answer:

The answer is [tex]\frac{13}{30}[/tex].

Step-by-step explanation:

Solve by completing fraction division.

Thus, solve [tex]\frac{5}{6} - \frac{2}{5}[/tex], since [tex]\frac{5}{6}[/tex] is larger than [tex]\frac{2}{5}[/tex].

[tex]\frac{5}{6} - \frac{2}{5}[/tex]

[tex]= \frac{25}{30} - \frac{12}{30}[/tex]

[tex]= \frac{13}{30}[/tex]

Hence, the answer is [tex]\frac{13}{30}[/tex].

Answer:

$6.88 B.

Step-by-step explanation:

The answer is $6.88. (Here's why )

Sales tax rate = 7.4 %

price of shoes = $ 93

Tax paid for a pair of shoes = 7.4 % x $ 93

=7.4/100 x 93

= 0.074 x 93

= 6.882

= $6.88

Answer:

The monthly cost for x slices of pizza is y=7x-5.5

Step-by-step explanation:

Consider the provided information.

The membership costs $5 per month and members get a discounted price of $1.50 per slice of pizza.

Let the cost of pizza is x and y represents the monthly cost.

Evan purchased 7 slices of pizza and membership cost $5 also the discounted price is $1.50 per slice of pizza.

Hence, the monthly cost for x slices of pizza is y=7x-5.5.

Answer:

8) 24 meters

9) 50.75 feet

10) 166 meters

Step-by-step explanation:

8) the perimeter is the sum of all sides of your shape. The shape is a rectangle, so you know 2 sides are the same length, 16.3 meters, and the other two sides are the size of the width, that is asked for.
so the perimeter = 2*length + 2*width which gives you the equation
80.6 = 2*16.3 + 2*x
then you solve it this way:
80.6 = 32.6 + 2x  | substract 32.6 on both sides
48 = 2x | divide by 2 on both sides
24 = x
so you know the width is 24 meters

9) again, the perimeter is the sum of all 3 sides of your triangle.
2 sides are each 36 and 3 quarters feet long.
so the equation is perimeter = 2*36 3/4 + unknown side, giving you the equation
124 1/4 = 2 * (36 3/4) + x
124.25 = 73.5 + x | substract 73.5 on both sides
50.75 = x
so the third side is 50.75 feet (or in other writing 50 and 3/4 feet)

10) so on the image you see that the park is a triangle. you are given the area and one side (along Second Ave) and you need to figure out the length of the side along Front Street. When you "double" the triangle, you get a rectangle.
The area of the imagined rectangle is 2 times the area of the triangle (the park), so the area of our rectangle is 13778.
The area of a rectangle is calculated width * length.
This gives you the equation
13778 = 83 * x | divide both sides by 83
166 = x
So the length of the park along Front Street is 166 meters.

Answer: 58.5 milligrams

Step-by-step explanation:

Answer:

58.5 mg

Step-by-step explanation:

Drink: 130% of RDA of vitamin X

RDA vitamin X = 45 mg

130% of 45 = mg in the drink

130% = 130/100 = 1.3

130% of 45 = 1.3 * 45 = 58.5

Thus, this new drink has 58.5 mg of vitamin.

Answer:x - the total sales

800 + 0.02 x ≥ 1600

0.02 x ≥ 1600 - 800

0.02 x ≥ 800

x ≥ 800 : 0.02

x ≥ 40,000

The total sales must be at least $40,000.

The graph of the equation using the slope and y-intercept is shown in image.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

A car salesperson earns a monthly salary of $800 per month plus $250 for each car sold.

Here, The equation y = 250x + 800 represents the total monthly salary.

Hence, Slope is,

⇒ m = 250

And, Y - intercept = 800

Thus, The graph of the equation using the slope and y-intercept is shown in image.

Answer:

Filling the chart to estimate the amount of each type of food that each family will receive is as follows:

Rounded Food Items and Families:

Food Item Number of Pounds Number of Families Estimated

Rounded Receiving Item Receiving

Chicken rolls 113 10 11.3

Mashed potatoes 7 12 0.6

Corn 28 10 2.8

Green bean 19 11 1.7

Casserole 5 3 1.7

What is an estimate?

An estimate is a rough calculation based on available information or rounded-off data.

Estimates are made to enable quick decisions without knowing complete details.

For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.

Original Data:

Food Item Number of Pounds Number of Families

Available Receiving Item

Chicken rolls 113.4 9

Mashed potatoes 6.6 12

Corn 28.5 10

Green bean 18.92 11

Casserole 5.37 3

Thus, as much as possible, some pounds of food items have been rounded to enable the estimate to be produced.

The Complete Table for Rounded Food Items and Families is shown below

An estimate is a rough computation made using information that is currently known or data that has been rounded off.

Estimates are created to help in decision-making quickly without having all the information.

So, In order to determine the quotients that represent the share of receiving households from each food group for this estimate, we employed the division procedure.

Original Data:

Food Item             Number of Pounds     Number of Families

                                    Available                   Receiving Item

Chicken rolls                    113.4                              9
