Answer:
42
Step-by-step explanation:
First condense all the numbers with exponents:
3² x 5³x 8 divided by 3 x 5³ x 8
27 x 125 x 8 divided by 3 x 27 x 8
Then multiply 27 , 125 ,and 8
27 x 125 x 8 =27000
Then multiply 3, 27 ,and 8
3 x 27 x 8 = 648
Then divide 27000 by 648
27000 / 648 = 41.6666666667
Which rounds to about: 42
You can make a ratio of red to overall colors and then that will give you the fraction, you might have to simplify it
Answer:
6
Step-by-step explanation:
Answer:
letter a is the correct answer
solve for the indicated variable means isolate that variable.
Ans(7)
P=IRT (T)
that means solve for T or make T alone on one side of equal.
To do that we just need to move IR on the left side
So we get:

Hence final answer will be 
-----
Ans(8)
2x-3y=8 (y)
-3y=8-2x

Ans(9)
V=LWH (L)

Ans(10)
A=2(L+W) (w)
A=2L+2W
A-2L=2W

Ans(11)
ax+by=c (y)
by=c-ax

Ans(12)
(R)
PN=R-C
PN+C=R
R=PN+C
