Answer:
C 109
Step-by-step explanation:
First add all the known angles inside the triangle first to get 109°
Then since all angles in a triangle add to 180°
you take away 109 from 180 so
180-109 which equals 71
Then since all angles on a straight line add up to 180°
you take 71 from 180 so
180-71 = 109
so x = 109°
The last two choices are appropriate.
Both give you f(1) = 7, f(2) = 9.50, f(3) = 12.00, ... as they should.
Answer:
Step-by-step explanation:
Let the total area be x.
<u>Farm exhibits are in 1/10 of the fairground:</u>
<u>Part of the fairground with rides:</u>
- r = x - f = x - 1/10x = 9/10x
<u>How much greater is the part of the fairground with rides than farm exhibits?</u>
- r/f = 9/10x : 1/10x = 9 times
