Answer:
93%
Step-by-step explanation:
1 + 3 + 21 + 35 = 60 = 100%
21 + 35 = 56 = x%
60 = 100%
56 = x%
60x = 56 * 100
x = 56* 100 / 60
x = 2*23*2*2*5*5 / 2*2*3*5
x = 23*2*5/3
x = 93%
Answer:
255
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
1
← is the n th term
with a = 1 and r = 2
The sum to n terms of a geometric series is
=
, thus
= 
=
- 1 = 256 - 1 = 255
