Step-by-step explanation:
It is convenient to let a spreadsheet compute each table value as 1.1 times the value on the previous line.
When the growth rate is 10% per year, the growth factor is 1 +10% = 1.10. This is the value that multiplies the investment each year.
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.
The answer would be 15.7.

Answer:
360cm
Step-by-step explanation:
The top square is 10 x 13 = 130
The middle square is 10 x 12 = 120
Both side triangles are 5 x 12 = 60. You would halve it but there are two triangles.
5 x 10 = 50
50 + 120 = 170
170 + 130 = 300
300 + 60 = 360
Equation would be (10 x 13) + (10 x 12) + (5 x 12/2) + (5 x 12/2) + (10 x 5)
The equation options seem like they are missing some numbers or something
