A slide is 10 feet long and 9.3 feet high. How long is its base, from the bottom of the ladder to the end of the slide?

3.92 feet

Step-by-step explanation:

The set up will be a right triangle

Given

Hypotenuse = 10feet (length of the ladder)

Opposite = 9.2 feet (Height of the slide)

Required

Length of the base l

USing the pythagoras theorem

adj^2  = hyp^2 - opp^2

l^2 = 10^2-9.2^2

l^2 = 100 - 84.64

l^2 = 15.36

l = 3.92 feet

Hence the base length is 3.92 feet

Control: No music

Step-by-step explanation:

A control group is the group that receives no changes in a experiment and is used as a benchmark. For example, a experiment where you wanted to know if plants can live without water, one of the treatments would be not giving them water. The control group would be the group that received water, like normal. Back to the question: Usually, music isn't played. Therefore no music would be the control group.

*Since you forgot to put the options, I can't be 100% sure, but I'm almost positive that this should be the answer.*

I hope this helped!
