The volume of a box for earrings is 216 cubic centimeters. What is the length of one edge of the box plz help it's due tm
Murrr4er [49]
I’m pretty positive you divide 216 by 4, since that’s the amount of sides a box normally has. The answer would be 54 cubic centimeters. Please let me know if I’m correct, hopefully this helped.

What is the order of the steps to solve for x in the equation 3x - 6x - 7 = 29?
Anna35 [415]

Answer:

3x - 6x - 7 = 29 <u>Given</u>

<u>-----------------------------------</u>

3x - 6x -7  = 29

           + 7   + 7     <u>Addition property of equality</u>

3x - 6x = 36

<u>--------------------------------------------------------------</u>

3x - 6x = 36

<u>(</u>3x + -6x) = 36         <u>Combine like terms</u>

-3x = 36    

<u>--------------------------------------------------------------</u>

-3x = 36

(-3x = 36)/ -3         <u>Division property of equality</u>

x = -12

<u />

Step-by-step explanation:

I tried to seperate the steps so you can go through them. First you had to add on both sides to take out the like terms, then combine the 3x and the  -6x to make -3x (easier to look at and divide), and finally divide to find X. the end product using X cannot be a negative because its a filler space for a real number.

Hope this helps :)

An air-filled rubber ball has a diameter of 6 in. If the air pressure within the ball is increased until the diameter becomes 7
Yakvenalex [24]

we are given

An air-filled rubber ball

d_0=6in

d=7in

we can use formula of the average normal strain in the rubber

\delta =\frac{\pi d - \pi d_0}{\pi d_0}

now, we can plug values

and we get

\delta =\frac{\pi*7 - \pi*6}{\pi* 6}

\delta =0.16667in/in...........Answer
