Answer:

A) 9m^3

Step-by-step explanation:

Raising something to the 1/2 power is the same as taking the square root.

The square root of 81 is 9.  The square root of m^6 is m^3.  Together, this gives us

9m^3.

That would be option A 
because square root of 81 is 9 and square root m^6 is m^3.

49 is 35% of what number?
NNADVOKAT [17]
We write this like this:

49=35%x

and we want to find the x.

let's invert the sides:

35%x=49.


35 is equal to 0.35

0.35*x=49

and now we only divide both sides by 0.35:

x=140

so the answer is 140.

(aternatively we can do it through fractions:

35/100*x=49
divide both sides by 7:

5/100*x=7

simplify the first fraction
1/20*x=7

and multiply by 20:

x=140

Solve for A. R = x(A + B) A = (R - B)/x A = (B - Rx)/x A = (R - Bx)/x
n200080 [17]
R = x(A + B)...distribute
R = Ax + Bx.....subtract Bx
R - Bx = Ax...divide both sides by x
(R - Bx) / x = A <==
