Add all the numbers of cases: 63 + 140 + 112 = 315
Each fraction is each number of cases divided by the total.

Truck: 63/315 = 1/5

Train: 140/315 = 4/9

Air: 112/315 = 16/45

A)
8^2+9^2=c^264+81=c^2
c^2=145c=sqrt 145c=12.04
B)
Pythagerean Theorum: 
A^2+B^2=C^2, where C is the hypotenuse and A and B are the other legs 
15^2=9^2+B^2 
225=81+B^2 
225-81=B^2 
144=B^2 (square root both sides) 
12=B

r1 is output from first roll
r2 is output from second roll

Since we want both outputs to be 6, therefore, the answer would be: (6,6)

Mafhvjfifjdfjujufugjfdu5\6 + 3\4 = ?
yKpoI14uk [10]
5/6 and 3/4 don’t have the same denominator so you have to change it to 10/12 and 9/12 to get them to be equivalent then add them together and get 19/12 simplify and get 1 7/12!
