Answer:
468
Step-by-step explanation:
Formula for infinite sum of geometric series is;
S_∞ = a1/(1 - r)
Where;
a1 is first term
r is common ratio
We are given;
a1 = 156
r = ⅔
Thus;
S_∞ = 156/(1 - ⅔)
S_∞ = 156/(⅓)
S_∞ = 468
Hopes this if it doesn’t I any so sorry if I got it wrong:
Answer: 6561
12/15
Divide 12 by 15 and then you should get 0.8
0.8 is obviously equal to 8/10ths or 80%
Hope this helps :)
68 because it is a perpendicular bisector we can assume that the angles full length is 90 degrees meaning you can just do 90-22=68
20/8=2’5”
So the larger triangle is bigger by 2.5
So you times 5’6” by 2.5 to get your answer which is 14 ft
Hope this helps
