Answer:
The y-coordinate would be 17.5
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
y ----->material needed in yards
x ----> number of curtains
we know that
For y=5, x=2
Find the value of the constant of proportionality k

substitute the given values of x and y

The linear equation is equal to

If the x-coordinate was 7
then
substitute in the equation x=7 and solve for y


therefore
The y-coordinate would be 17.5
Answer:
60%
Step-by-step explanation:
55 - 22 = 33
33/55 = 0.6
0.6*100 = 60%
6.1inches * 80% = 4.88inches
100% - 15% = 85%
4.88 inches * 85% = 4.148inches
Answer:
If we are given diameter and we need to find radius then,
Radius(r) = Diameter(d) ÷ 2
⇒ r = d÷2
So here d = 41
So r = d÷2
⇒ r = 41 ÷ 2
⇒ r = 20.5
