Sam's age is 125% of mary's age. mary's age is p% of sam's age. what is the value of p?
1 answer:
Let Sam be (S+8) years while his sister is S years.
S(S+8) = 105
S^2+8S-105 = 0
(S+15)(S-7) = 0
Sam’s sister is 7 years and Sam is 15 years old.

180-141=39°
x = 39°
Inverse variation means y=k/x, we are given (3,6) so
6=k/3
k=18 so
y=18/x
y=18/27
y=2/3
