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: 140
Step-by-step explanation: since 4 = 40 then 2 would also be 40 because they are the same angle (Keep in mind that a line is 180 degrees) 180-40=140! Good luck! :D
a). 0.45 with a line over the 45 means 0.45454545454545... forever.
It's equivalent to 45/99 which is <em>5/11</em> .
b). 0.45 with a line over the 5 means 0.455555555... forever.
It's equivalent to (0.4 + 0.555555.../10)
The 0.4 part is 4/10
The 0.5555555555.../10 part is 5/90 .
(4/10) + (5/90) = <em>41/90 </em>
c). 0.45 means 45/100 . That's <em> 9/20</em> .
I don't think you're supposed to be posting unit test questions on Brainly.
