Answer:
<h2>D</h2>
Step-by-step explanation:
If pair of ratios does form a true proportion then:



It could be anything they are both variables.
The answer is 150 because 30+150=180
That would be A :D It would be A because you would do keep change flip. You would keep 5/6, change the division sign to multiplication, then flip the 5/16 to 16/5 (the reciprocal)
We know that
if the dilated circle <span>passes through the point (4, 0)
so
the new radius is the distance from the origin to point (4,0)
d=</span>√[(4-0)²+0²]-----> d=√16------> d=4 units
the new radius is 4 units
original radius is 1 units
[new radius]=[scale]*[original radius]
scale=new radius/original radius-----> scale=4/1-----> 4
the answer is
<span>the scale factor of dilation is 4</span>
