The length of a rectangular prism is 8

Lena [83]

Surface area is:

$W=width$
$L=length$
$H=height$

$S=2*(L*W+L*H+W*H)$

replacing the values

$250=2*(8*W+8*1+W*1)$

$250=2*(8*W+8+W)$

$250=2*(9*W+8)$

dived each member by 2

$125=9W+8$

$9W=125-8$

$9W=117$

$\boxed{\boxed{W=13~unit~of~measure}}$

The volume of a rectangular prism is

$V=L*H*W$

$V=8*1*13$

$\boxed{\boxed{V=104~unit~of~volume}}$

An instructor makes $15 more per hour than an assistant. If the combined hourly wage of the instructor and assistant is $65, wha

mezya [45]

X= assistant's wage
x+15= instructor's wage

Add their wages set equal to $65

x + (x + 15)= 65
combine like terms

2x + 15= 65
subtract 15 from both sides

2x= 50
divide both sides by 2

x= $25 assistant's wage

x+15= 25 + 15= $40 instructor's wage

ANSWER: (C) $25 hourly wage of assistant

Hope this helps! :)
