You have $11 and earn $0.50 for each cup of orange juice you sell. Write an equation in two variables that represents the total amount A (in dollars) you have after selling j cups of orange juice.

A= ??

Answers

your answer would be A= $11+ j x (.50)
A= total which is based off of how many cups (j) you sell of OJ... plus the $11 you started with.

Answer:

A = 0.50j

Step-by-step explanation:

Your total savings, A, are equal to the $0.50 you earn times the number of cups you sell, j.

Or, A = 0.50j.

Good luck :) I hope this helps

There are 8 boys for every 3 girls at a concert. If there are 220 people at the concert, what is the difference between the total number of boys and girls at the concert?

Answers

Answer:

100

Step-by-step explanation:

First we get the ratio of 8:3 for the amount of boys to girls.

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 8 + 3 = 11

Part A = 8 and Part B = 3 are numerators for each fraction.

The fractions are then:

8/11 and 3/11

8/11 for boys

and 3/11 for the girls

Now we just multiply 220 by these fractions:

220 * 8/11 = 160

220 * 3/11 = 60

Then subtract:

160 - 60 = 100

Answer:

There are 60 girls and 160 boys

From the table, the ratio of white socks to brown socks is 9/8

Select two ratios equivalent to the ratio of white socks to brown socks.

A) 35/32 B) 40/46 C) 36/33 D) 45/40

Answers

Answer:

Step-by-step explanation:

To find an equivalent ratio it must be multiplied or divided by the same number.

I multiplied 8 by 5 which got me 40

Then I multiplied 9 by 5 which got me 45

This means the equivalent ratio is 45/40

A solid has volume 6 cubic units and surface area 22 square units. The solid is dilated, and the image has a volume of 48 cubic units. What is the surface area of the image?

Answers

The surface area is 176 because first multiply 22 by 48 to get 1056 then divide that by 6 to get 176 so the surface area is 176units

The surface area of image is 81 square units.

What is dilation?

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor.

What is image?

The new figure obtained after dilation is called image.

What is scale factor?

Scale factor is the ratio of the sizes of the original figure with the dilated figure.

Scale factor formula

[tex]scale factor = \frac{dimension of new shape }{dimension of original shape}[/tex]

According to the given question

Volume of solid = 6 cubic units

Surface area of solid = 22 square units

volume of image = 48 cubic units

therefore,

ratio of volumes = ratio of lengths

[tex]\frac{48}{6}[/tex] [tex]=8:1[/tex]

⇒ratio of sides = [tex]\sqrt[3]{8} :\sqrt[3]{1}[/tex]

⇒ ratio of sides = 2 : 1

Ratio of surface area of solid and image = square of ratio of sides = 4:1

⇒[tex]\frac{surface area of image }{surface area of solid} = \frac{4}{1}[/tex]

⇒[tex]\frac{surface area of image }{22} = \frac{4}{1}[/tex]

⇒ surface area of image = 4×21

⇒ surface area of image = 81square units.

Use the information to answer the following question.

The bottom of a swimming pool is 10 feet below the surface of the water in the pool. The surface of the water is represented by the number 0, and the bottom of the pool is represented by the number -10. The pool’s diving board is the same distance above the surface of the water as the bottom of the pool is below the surface of the water.

What number represents the location of the diving board?

A.
20

B.
0

C.
10

D.
1/10

Answers

Answer:

Step-by-step explanation:

Since the difference between 0 and -10 is 10, this means that the difference between the diving board and the pool also has to be 10. Therefore, the diving board is 10 feet above the water since 0+10 is 10.

C. since it’s above the surface of the pool which is 0 it’s at a positive elevation of 10

What are the measurements of angles 1, 2, 4, 5, 6, 7, and 8?

Geometry

Short answer

Answers

Angles 1,6,8 = 55
Angles 2,4,5,7 = 125

Answer:

1=55°

2=125°

4=125°

5=125°

6=55°

7=125°

8=55°

Step-by-step explanation:

7= 125° because a line is 180°, so 55° + angle 7 = 180°, using simple algebra we can subtract 55 from both sides getting angle 7 = 125°

8= 55° because vertical angles are always congruent

4= 125° because all vertical angles are congruent

6= 55° because alternate interior angles are always congruent so angle 6 = 55°

1= 55° because vertical angles are always congruent

2=125° because alternate interior angles are always congruent so angle 2 = angle 7

5=125° because vertical angles are always congruent

Rewrite the following equation in slope-intercept form.

18x + 14y + 15 = 0

Answers

Answer:

y=-9/7x-15/14

Step-by-step explanation:

Slope-intercept form is y=mx+b

The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.

18x+14y+15=0

-15 -15

18x+14y=-15

-18x -18x

14y=-15-18x

14y=-18x-15

÷14 ÷14

y=-9/7x-15/14

Hope this helps!

The correct answer would be y=-9/7x-15/14(:

Answer:

a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.

b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.
