Answer:

B; or 8.5

Step-by-step explanation:

Mean is also known for average of the numbers.

To find the mean simply add all the numbers together and divide by the quantity of the numbers given. So first add up "8 + 10 + 6 + 4 + 12 + 6 + 8 + 14" this all equals to 68 and since the total quantity of the numbers given is 8, so divide 68 by 8 which gives the answer as 8.5.

Hope this helps!

Answer:

C.

Step-by-step explanation:

The typical value is marked by the red triangle. It's about 6 in the Set A, and around 4 in set B, so it's clearly greater is set A.

The spread relates to how spread out the elements are, and we can clearly see that in set a it's between around 5 and 7,  while for set B it's 1 to 8, telling us that set B has greater spread.

Answer:

Set A = 30

Set B = 22

I think its B

Answer:

5/6 or 50 minutes

Step-by-step explanation:

Ok so first thing you want to do is find the rates of both the girls and add them up:

Amanda can finish 1 room in 2 hours

hence,

1/2   ( rooms/hours)

And we know Monica can paint the same room in 3 hours:

1/3

Now add them together such that the equation is \:

1/2+1/3=1/x .      x being the total hours they can finish the room together.

Once you add those you should get 5/6!!!

Answer:

1. 3,168 in³

2. [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

1. The total volume of the tank - as calculated by the formula for a rectangular prism - [tex]V=LWH[/tex], where L is length, W is width, and H is height. 15 · 24 · 11 = 3,960 in³. Next, we divide 3,960 by five to get 792. If 792 in³ is the air at the top, we can then subtract that from 3,960 and get 3,168. So there are 3,168 in³ of water in the tank.

2. If we dump 3,168 in³ of water into a 12,672 in³ tank, then [tex]\frac{3,168}{12,672}[/tex] of the tank will be full. Simplified, that is [tex]\frac{1}{4}[/tex]. So that means [tex]\frac{3}{4}[/tex] of the tank will be empty.

Hope this helps! Feel free to ask any questions!

Answer:

$77

Step-by-step explanation:

Let A represent the total amount of the checks.  Then:

$64 - (-$13) = $77

The total amount of the checks was $77.

Answer - Part A:

I would say "whole".

Step-by-step explanation:

So, it talks about the discount being 30% or $24 dollars. This is only part of the original price.

Where, the original price is the total price. So, the means that it is the whole price.

Just to help:

Answer - Part B: The original cost of the jeans are $80.

Step-by-step explanation:

If you find 30% of 80, then you will have to do x/80 = 30/100. Next, you will cross multiply (x times 100 and 80 times 30), which gives you 100x and 2,400. Now, you will divide both numbers by 100. You should now have x and 24. So, x = 24.

So, see? 30% of 80 is $24.

(This can also be used to show your work)

Answer:

m∠G = 58°

m∠J = 122°

Step-by-step explanation:

m∠G:

Straight line is 180°, so 32° + 90° + m∠G = 180°

m∠G  = 180° - 32° - 90°

m∠G  = 58°

m∠J:

vertical angles are equal to each other

m∠J = 32° + 90°

m∠J = 122°

Answer:

a. EQUATION : 180 - (90+32) =

b. Angle G = 58*

c. equation : 180 - 58* =

d. Angle J = 122*

Answer:

Step-by-step explanation:

13, 15, 27   and    13, 27, 15

you could rearrange the order but they would still be the same two triangles in different rotated positions:

15, 13, 27    is the same as 13, 27, 15, just rotated

15, 27, 13    is the same as 13, 15, 27, just rotated

27, 13, 15    is the same as 13, 15, 27, just rotated

27, 15, 13    is the same as 13, 27, 15, just rotated

Step-by-step explanation:

340.4 cubic inches (correct)

Approx. answer is 341.53 cubic inches (used to check work)

Step-by-step explanation:

Find volume of triangular prism

find area of base of triangular pyramid

multiply by 7

divide by 3

add to area of prism

64.4 plus 277.13 equals 341.53

Answer:

74

Step-by-step explanation:

Answer:

74 buses

Step-by-step explanation:

5,892 divided by 80 is 73.65. You can't have 0.65 of a bus so you round it up to 74.

Answer:

x = 76

Step-by-step explanation:

The angles are same side interior angles and same side interior angles are supplementary, which means they add to 180

x+104 = 180

Subtract 104 from each side

x+104-104 = 180-104

x =76

Answer:

B

Step-by-step explanation:

Answer:

It is just right

Step-by-step explanation:

This is a problem that involves a few steps.

This is the fraction we would in order to solve this problem. [tex]\frac{Liters}{Teabags} \\[/tex]

Kermits favorite tea is [tex]\frac{2}{15}[/tex]

Peggy made a tea with [tex]\frac{12}{90}[/tex]

Now we think:

[tex]2 * x = 12\\x = 6\\\\15 * x = 90\\x = 6[/tex]

Since both numbers from 2/15 can be multiplied by 6 to get 12/90, the tea is just right.

2/15 is equal to 12/90

Answer:

2500 ft²

Step-by-step explanation:

The missing area at lower right in the diagram has dimensions...

(4-2 1/4) by (3 - 1 3/4) by (1 1/4)

Then area of that "Missing" space is (1.75)(1.25)= 2.1875 . . . . square inches. The area of the enclosing rectangle is ... (4 in) (3 in) = 12 square inches the area in the diagram representing the store is... 12 in² -2.1875 in² = 9.8125 in²

_

Each square inch on that diagram represents an actual area of (1 in)×(1 in) → (16 ft)×(16 ft) = 265 ft²

Then the actual store area is....

9.8125(256 ft²) = 2512 ft²

Rounded to the nearest 50 ft², this is 2500 ft².
