Answer:
Step-by-step explanation:
The sum of an infinite geometric series is expressed according to the formula;
where;
a is the first term of the series
r is the common ratio
If the sum of an infinite geometric series is three times the first term, this is expressed as 
Substitute into the formula above to get the common ratio r;
open the parenthesis
subtract 3 from both sides
<em>Hence the common ratio of this series is </em><em></em>

Answer:
60.72
Step-by-step explanation:
Monday: 60 degrees
Tuesday: temperature increases by 10 percent
60 + 10% of 60
60 + .10*60 = 70 +6 = 66
Wednesday: temperature decreases by 8 percent
66 - 8%of 66
66 - .08*66 = 66 -5.28=60.72
