The real cube root is 0.03 because...
(0.000027)^1/3 = (27 x 10^-6)^1/3 = 3 x 10^-2 = 0.03
The answer is true because
(20) 3 = 10 (6)
60 = 60
Answer:
A = 120
Step-by-step explanation:

Hey there! :D
Let's keep the fraction 5/7 in mind. We should be able to reduce everything to 5/7.
15:21 (divide both by 3) you get 5:7. That is equivalent.
10 to 14. Divide both by 2. 5 to 7. That is equivalent.
The correct answer is 28/20. That is not equivalent.
I hope this helps!

So.. first off.. let's keep in mind that if 30% of acid is there in a solution, say the solution is some amount of liquid and 30% of that total liquid only is the acid, so if the amount of the liquid is say "x", then 30% of that is just (30/100) * x, or 0.3x.
now, we'll do the same for the 55% and the 45%, use the decimal format to get how much quantity in the substance is of acid.
now, whatever "x" and "y" are, we know that
x + 60 = y, and we also know that
0.3x + 33 = 0.45y.
