50 POINTS<br><br> What is the volume of this?

Temka [501]

The volume is 30.

You need to subtract the volume of the smaller box from that of the bigger box. It is written as such:
V = (3*3*4) -(2*1*3)
V = 36 -6
V = 30

The sum of 13 and twice a number

Setler79 [48]

This would be 13+2x because if x is the number, then 2 times it would be 2x and the sum means addition so it would be 13+2x

PLEASE HELP ME!!!!!!!!!!!!!!!!!!

lilavasa [31]

Answer:

a) 4 - $vt - d = \frac{1}{2} at^{2}$

b) 1 - $2(vt - d) = at^{2}$

c) 6 - $\frac{2(vt - d)}{t^{2}} = a$

Step-by-step explanation:

It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.

We start with:

$d = vt - \frac{1}{2} at^{2}$

We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):

$vt - d = \frac{1}{2} at^{2}$

Then we multiply each side by 2 to get rid of the 1/2, answer #1:

$2(vt - d) = at^{2}$

Finally, we divide each side by t^2 to isolate a (answer #6):

$\frac{2(vt - d)}{t^{2}} = a$
