Answer:
An 18 sided shape.
Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon
Answer:
10 %
Step-by-step explanation:
let the percent be x
according to the question
7.8 = x % 0f 78
7.8 = x /100 * 78
7.8*100 = 78x
780 = 78x
780/78 = x
10 = x
d=2r, r = 2.5
A= πr2
Area = 3.14 ⋅ 2.5 ⋅ 2 = 15.7 
The <u>correct answer</u> is:
<span>A) Yes, the points shown on the line would be part of y = 0.5x.
Explanation:
Looking at the graph, the line goes through (0, 0). If x=0, we have
y=0.5(0)=0.
This is the y-coordinate of the point, so it goes through this.
The equation for this line is in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept. In this equation, m=0.5 and b=0. This means the slope is 0.5 or 1/2; since slope is rise/run, this means the line rises 1 for every horizontal increase of 2.
This means starting from (0, 0), we would go up 1 and over 2, creating the point (2, 1). Looking at the graph, the line goes through this point.
Next we would go up 1 and over 2 again, to (4, 2). Again, the line goes through this point.
We could follow all of the points on this line and they all fit.</span>
