Answer:
127
Step-by-step explanation:
The sum of 7 terms of the series 1 +2 +4 +... with first term 1 and common ratio 2 is given by ...
Sn = a1 × (r^n -1)/(r -1) . . . . . . first term a1, common ratio r
S7 = 1 × (2^7 -1)/(2 -1) = (128 -1)/1 = 127
At the end of 6 months, the club will have 127 members.
3x(1.05) = 3.15x
1.05x + 1.05x + 1.05x = 3.15x
Where’s the question mate?!
No, 5/6 is greater.
1) First, you have to get a common denominator, lets use 12
2) To get from 6 to 12 you would multiply times 2
3) Do the same to the numerator(the top number) which is to multiply 5 x 2
4) 5 x 2= 10
5) So, now your fraction has become 10/12
And let me ask you, which is bigger, 10/12 or 2/12
(10/12 is bigger and 2/12 is less)
