Two figures are similar are one of them can be obtained from the other with some transformations (reflections, translations, rotations, dilations) <span> . The circle is defined by only one length - the radius.

To prove that all circles are similar you would use the sequence of similarity translation and dilation.
A translation, followed by a dilation with scale factor r2/r1 will map one circle onto the other, thus proving that the circles are similar.
Answer:40 min
Step-by-step explanation:
5+.10x=3+.15x
-.10. -.10
5= 3+.05x
-3. -3
2=.05x
Divide by .05

Answer:
Hi! I believe this is your answer:
$750
Step by step explanation:
interest + interest = total interest
0.08*x + 0.09*(9000-x) = 750 dollars
0.08x + 810 - 0.09x = 750
-0.01x = 750 - 810 = -60 ====> x = %28-60%29%2F%28-0.01%29 = 6000.
Final answer:
$6000 was invested at 8%. The rest 9000-6000 = 3000 dollars were invested at 9%.
Check. 0.08*6000 + 0.09*3000 = 480 + 270 = 750 dollars.
