The answer is 28%

Step-by-step explanation:

So no matter what size bottle you have fill 71.43% of it with the 70/30 mix of isopropyl alcohol and the rest with water. If you want to determine the percentage of water just take the difference between the 71.43% and a full bottle which is represented by 1. Each bottle should then contain 28.57% distilled water no matter what size the bottle is.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
