Pls answer dont sweat it though u tried ur best right (its worth branliest)

Answers

Answer:

A

Step-by-step explanation:

B is 180

C looks like 30-ish

D looks like 270

so A is the only one that looks to be 45

Answer:

C

Step-by-step explanation:

45/360 covers about 1/8 of the entire degress of a circle, this means the image that corresponse with be on the smaller side.

a- this seems closer to 1/4 and would not be the best match

b- this covers half, so this is much to large to correspond

c- this is the closest eyballing it, as it looks small enough to cover 1/8th as well as be properly notated

d- this is smaller and could be correct except the notation on it shows that it is going around the outside (so 360- that angle)

A survey of a group of seventh-graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.


Students

A dot plot titled Students. A number line going from 0 to 9 labeled the number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.


Teachers

A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.


Based on the shape of the two-dot plots, which statements correctly compare them? Select three choices.

The center of the data for students has a value less than that of the center of the data for teachers.

The center of the data is to the right of the dot plot for both teachers and students.

There is a greater variation in the data for teachers than for students.

Both sets of data cluster around 2.

The same number of teachers as students were surveyed.

The histogram shows the number of items sold at The Clothes Horse one week. About what percent of items sold cost less than $40

A. 55%
B. 56%
C. 34%
D. 25%

Answers

I’m pretty sure the correct answer to this is D
The answer is C
because if you were to add up all the frequencies together of each price range it would be 320 and the total frequency that cost less than $40 is 110, so if you divide 110 and 320 you’d get a decimal of 0.34 which is 34%

Answer:

Step-by-step explanation:

Does a=7 make 7a= 56?
btw I hate math I am bad at it but I am good with other stuff

Answers

Answer:

No, 7a does not equal 56. If a = 7, then 7a would equal 7 * 7. And, 7 * 7 = 49.

ᗩᑎՏᗯᗴᖇ:

a = 7

[tex]7a = 56 \\ 7 \times 7 = 56 \\ 49 = 56[/tex]

=> 49 is not equal to 56, so a=7 will not make 7a= 56.

2x+6+12=90
2x+18=90
2x=90-18
2x=72
x=36

Answer:

Step-by-step explanation:

Plug in each number:

For A. you will do this: 2*78 + 6 = 156 + 6 = 162. So, no. You need 90 degrees.

For B. you will do this: 2*72 + 6 = 144 + 6 = 150. So, no. You need 90 degrees.

For C. you will do this: 2*42 + 6 = 84 + 6 = 90. This is a possible answer choice, but you should keep going just in case.

For D. you will do this: 2*36 + 6 = 72 + 6 = 78. So, no because you need 90 degrees for a right angle. (A right angle is 90 degrees)

Hope this helps! :)

Find the radius of a sphere with a volume of 972π cubic millimeters.

Answers

Answer:

The radius is 9 mm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3  where r is the radius

972 pi  = 4/3 pi r^3

Divide each side by pi

972 = 4/3 r^3

Multiply each side by 3/4 to isolate r^3

3/4 * 972 = 4/3 * 3/4 r^3

729 = r^3

Take the cube root of each side

(729) ^ (1/3) = (r^3) ^ (1/3)

9 = r

The radius is 9 mm

Answer:

9 mm

You asked amusement park visitors the question “How many times did you ride the Ferris wheel today?” as they left the park.

Four people said they rode a Ferris wheel 5 times. Explain how this would be shown on a dot plot.

Answers

Answer:

Draw an xy axis. On the x-axis, put "number of times person rode the Ferris wheel" or something along those lines. For the y axis, put "frequency". For x = 5, you'll have four dots stacked on top of each other at this x value. I suggest having a slight gap between each dot so you can tell them apart. The four dots represent the four people who said they rode the Ferris wheel five times.
