So, first things first, you need to get a common denominator for the two fractions.
That would be 40.
Which one is larger?
By how much is it larger?
Remember to reduce.
Answer:
this function model grows.
Step-by-step explanation:
The value of b, 1.56, is greater than 1.
Triangle SET is similar to triangle SAR, so corresponding sides have the same ratio. This means
... ST : SR = ET : AR = 8.19 : 6.37
Then ST : TR = 8.19 : (6.37+8.19) = 8.19 : 14.56
Using division symbols, this is
... ST/TR = 8.19/14.56
Multiplying by TR gives
... ST = TR×(8.19/14.56) = 20.8×8.19/14.56
... ST = 11.7
