In a parking lot, 43% of the cars have gps. express this percent as a decimal.

0.43

Think of 43% as 43.0%

Move the decimal 2 spots to the left to go from 43.0 to 0.43

Alternatively, use a calculator to find that 43% = 43/100 = 0.43

"percent" means "per 100", so that's why we're dividing over 100.

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
