1080 clothespins makes 90 chairs and we need to find out how many clothespins it takes to make 1 chair.
We can set up a proportion of the number of chairs to the number of clothespins because of the proportional relationship.
x is the number of clothes pins for 1 chair
Cross multiply to get
90*x= 1080*1
Divide both sides by 90 to isolate x
x = 12 clothespins
It takes 12 clothespins to make 1 chair.

I got it right on my quiz :)
Hope this helps!
The answer should be 9sqrt2 because the equation for finding the legs on a 45-45-90 triangle is hypotenuse/sqrt2.
110° because interior angles are half the measure of their arc
Answer:
a) The original price of the bag was $90
b) Lina was having $74
Step-by-step explanation:
Let the original price of the bags be 'x'
and,
the money Lina had be 'y'
then according to the question
Price of red bag after 15% discount = x - 0.15x = 0.85x
Price of red bag after 20% discount = x - 0.20x = 0.80x
also,
0.85x = y + $2.5 ...........(1)
0.80x = y - $2 .............(2)
subtracting the equation (2) from (1), we get
0.85x = y + $2.5
- ( 0.80x = y - $2 )
===================
0.05x = $4.5
or
x = $90
a) The original price of the bag was $90
b) on substituting the value of x in the equation (1), we get
0.85 × 90 = y + $2.5
or
76.5 = y + $2.5
or
y = $74
Hence, Lina was having $74
