Answer:
P(even,blue) = 3/6 x 1/9 which is 1/18
Step-by-step explanation:
A and b are legs
a^2+b^2=c^2
lets say
a>b
so
a=13+3b
c=14+3b
a^2+b^2=c^2
(13+3b)^2+b^2=(14+3b)^2
9b^2+78b+169+b^2=9b^2+84b+196
10b^2+78b+169=9b^2+84b+196
minus 9b^2 both sides
b^2+78b+169=84b+196
minus 84b both sides
b^2-6b+169=196
minus 196 both sides
b^2-6b-27=0
factor
(b+3)(b-9)=0
set to zero
b+3=0
b=-3, false, dimentions cannot be negative
b-9=0
b=9
shorter leg is 9
a=13+3b
a=13+3(9)
a=13+27
a=40
c=14+3b
c=14+27
c=41
side legnths are
9in, 40in, 41in
38.4/x=100/32.5
multiple both sides of the equation by x
38.4=3.07692307692*x
divide both sides by the big number to get x
38.4/(big number)=x
x=12.48
Im pretty sure its $140 US Dollars
Hope this helped ;)
