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:

Number one the base is 24 and the Volume is 120

Number two the base is also 24 and the Volume is 240.

Step-by-step explanation:

For #1:

For the first one the area of the base is 8x3 which equals 24 so for base Number 1 its 24.

All we got to do to figure out the volume is multiply by 10 *the height* and then divide by 2 because we are finding the volume of a pyramid. 24x10 = 240/2 = 120. So the volume for Number 1 is 120.

For #2:

It has the exact same number except we are dealing with a rectangular prism which means at the end we don't have to divide by 2. For the base its  8 x 3 = 24 the same as the pyramid.  For the volume-  8 x 3 = 24 x 10 = 240 which means the volume is 240. And of course don't forget the unit yards³

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.

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

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! :)

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)

X=4

Answer:

Step 1 - Subtract 12 from both sides of the equation.

Step 2 - Simplify.

Step 3 - Subtract 10x from both sides of the equation.+

Step 4 - Simplify

Step 5 - Divide both sides of the equation by the same term.

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

ᗩᑎՏᗯᗴᖇ:

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