Your friend is 1.25 times taller than you. your friend is 64.5 inches tall. how tall are you?

To do a problem like this, multiply the base height by the rate.  So here is how you do it:

64.5 times 1.25

The easiest way is to get a calculator and plug in the equation

Your answer should be 80.625

*If you multiply by hand, remember to move the decimal back to the left three places.*

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

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
