Answer:

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:

B or 2y² + 18x

Step-by-step explanation:

4y² + 6x - 2y² + 12x

combine like terms together:

4y² + (-2y²) = 2y²

6x + 12x = 18x

2y² + 18x = B

I hope this helps you!

Answer:

B.

Christina's price per poster is cheaper than Stacie's price per poster.

Step-by-step explanation:

Divide each value

Answer:

B. 10,368 square yards

Step-by-step explanation:

120x90= 10800

24x18=432

10800-432= 10,368 square yards

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*

in circle

measure is like a tip of nickel

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:

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:

25 boxes

Step-by-step explanation:

1)  Volume of each box = edge * edge * edge

                                        = 2.5 * 2.5 * 2.5

                                        = 15.625 cubic feet

Find the volume of the cargo hold and the volume of one box.

When you load one box, the space of the cargo hold will reduce. So when you add more boxes, the space of cargo hold will reduce continuously. So continuous subtraction is divsion.

To find the number of boxes, divide the volume of cargo hold by the volume of each box.

Number of boxes = Volume of cargo hold÷ volume of one box

                             [tex]= \frac{length *width * height}{edge * edge*edge}\\\\= \frac{15*7.5*7.5}{2.5*2.5*2.5}\\\\= 54[/tex]

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

Answer:

y=6x

Step-by-step explanation:

As x increases, y increases by 6.

(In context of graph) As a week passes, Jack’s savings account increases by $6.

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!!!
