R = 112/1000 x 4 = 0.028 x 100 (find percentage) = 2.8%
1920 divided by 12 is 160
Answer:
I'm pretty sure the first question is hexagon. the second question I think is a point and a triangle but I am not sure.
Answer:
C. Multiply the bottom equation by 2
Step-by-step explanation:
-2x+ 4y= 10
3x- 2y =-7
We want to multiply the second equation by 2
-2x+ 4y= 10
6x- 4y =-14
------------------
4x +0y = -4
The distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.
<h3>Circumference, diameter and radius</h3>
Since the circumference of the CD is about 37.7cm
We can determine the radius of the CD as follows;
Circumference, C = 37.7 = 2 π × r.
However, the diameter of the hole in the center is; 1.5cm, therefore, the radius of the hole in the center is; 1.5/2 = 0.75cm.
Ultimately, the distance from the outside edge of the CD to the inside edge is; 6.0 - 0.75 = 5.25cm.
