A storage box has a volume of 56 cubic inches, and the base of the box is 4 inches by 4 inches.

What is the height of the box?

Answers

The height of the box is 3.5in or 3 1/2in
Ok, so first we need the equation. So we know that v=b*w*h. We know that the base is 4 inches and the width is 4 inches as well. So we get the equation v=4*4*h. The volume is also given so the equation changes to 56=4*4*h. So first we multiply the numbers we have to get 56=16*h. Then we divide 16 on both sides. 56/16 is 3.5. We end up with 3.5=h. So the answer is 3.5 inches. You can also put this back in to make sure it is right. To 56=4*4*3.5 is true. So therefore, the answer is 3.5 inches.

Match each expression in column A with an equivalent expression from column B.



Column A

12r + t − 4r + 6t
(12r + 2t) − (4r + 10t)
12(r + t) − 6(r + t) + 4(r + t) − 2(r + t)


Column B

8(r − t)
8(r + t)
8r + 7t


12r + t − 4r + 6t

Answers

Answer:

see answers below to match them

Step-by-step explanation:

12r + t - 4r + 6t

=12r - 4r + t + 6t

=8r + 7t

(12r+2t) - (4r+10t)

=12r + 2t - 4r - 10t

=8r - 8t

=8(r-t)

12(r+t)-6(r+t)+4(r+t)-2(r+t)

=(12-6+4-2)(r+t)

=8(r+t)

Step-by-step explanation:

Answer:

[tex]b=14.0524019299[/tex]

Step-by-step explanation:

Use the Pythagorean theorem to solve: [tex]a^2+b^2=c^2[/tex]

[tex](6.3)^2+b^2=(15.4)^2[/tex]                <-- plug in a and c values into equation

[tex]39.69+b^2=237.16[/tex]                <-- take out parentheses

[tex]b^2=197.47[/tex]                              <-- subtract 39.69 from both sides

[tex]b=14.0524019299[/tex]                  <-- take the square root of 197.47

Answer:

37

Step-by-step explanation:

20 + 13 = 33

so 70 - 33 = 37 so the answer is 37

Answer+explanation

so subtract the diffference of 20 and 13 from 70

so first we find the difference and then subtract that from 70

use parenthases so

difference of 20 and 13 is equal to (20-13)

subtract that from 70

70-(20-13)

so you would do the pemdas and get 7 for the inside parethasees then do

70-7=63
