Answer:
The graph in the attached figure
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 or unit rate of the line and the line passes through the origin
so
In this problem we have

substitute
using a graphing tool
The graph in the attached figure
Circumference = 2 pi r = 20 pi
corresponding to 360 degrees
so an arc of 4pi feet will have a degree measure of 5pi / 20pi * 360 = 1/4 * 360 = 90 degrees
Answer:
<h2>1.20</h2>
Step-by-step explanation:
1y + 12 = 6 (1y + 1)
1y + 12= 6y + 6
12 - 6 = 6y - 1y
6 = 5y
y = 6/5
y = 1.2
I don't what you meant by rounding to 2 decimal points so my answer is
<h2>1.20</h2>
The GCF is 5
Hope this helps
