If

denotes the sum of the first

terms of a geometric series with first term

and common ratio

, then





Using summation notation, you have

In this case, you have

,

, and

. So the value of the sum is

Rounded to the nearest whole number, the answer would be 3.

Answer:
The transformation is rigid because the corresponding side lengths and angles are congruent.
Step-by-step explanation:
Since we have congruent triangles (not similar triangles), they will have to have the same length and angles throughout your transformation. Therefore, our answer is the 1st Option.
-5m-20-80+50m=0
45m=100
m= 20/9
Answer: 45%
Step-by-step explanation:
Converting the word problem into words, we have:
18= x/100*40
Solving for it, we get that x=45.
