1 It takes Elizabeth 24 minutes to paint 4 chairs. If
Elizabeth paints at a constant rate, what is the
constant of proportionality that relates y, the
number of chairs painted in x minutes?

k = 0.167

Step-by-step explanation:

This is a direct proportion. That is as the number of chairs increases, so does the number of minutes needed.

y=number of chairs

x = time in minutes.

y = k x

4 = k * 24            Divide by 24

4/24 = k

You could leave it that way.

or you could do the division

k = 1/6 = 0.167

y = 0.167 x

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
