Answer:
8:7
Step-by-step explanation:
A <em>scale</em> factor (SF) is the ratio of two corresponding side lengths in similar figures.
The two circles are the similar figures, and the SF is the ratio of their corresponding radii.
SF = outer radius/inner radius
= (35 + 5)/35
= 40/35
= 8/7
The scale factor is 8:7.
Answer:
2/7 < 5/6
1/5 < 3/4
Step-by-step explanation:
A. because when you divide all of the groups, 17.699/11, 41.834/26, 54.706/34, they all get the same answer, 1.609, so they are all proportional, because the relationships stays the same
Hope this helps!
I think that answer is 0.2.
