Answer:
The ratio that compares the championships won by Australia to the total number won by the United States is equal to 
Step-by-step explanation:
Observing the graph
we know that
The championships won by Australia are 6
The championships won by the United States are 15
To find out the ratio, divide the championships won by Australia by the total number won by the United States.
so

Simplify
Divide by 3 boths (numerator and denominator)

Convert to percentage

that means
For every 2 championships won by Australia the United States won 5
or
The championships won by Australia are 40% of the championships won by the United States
The correct answer is B) 117
Step-by-step explanation:
By Pythagoras' Theorem,

where c is always the largest number.
a and b can be interchangeable between the 2nd largest and the 3rd largest numbers.
Given a = 8, b = 15 and c = 17,

Since c^2 = a^2 + b^2 , 8 , 15 and 17 are pythagorean triplets.
Now let's move on to 9, 40 and 41.

Since c^2 = a^2 + b^2 , 9 , 40 and 41 are pythagorean triplets.
Last let's move on to 4,7 and 8.

Since a^2+b^2 IS NOT EQUAL to c^2, 4,7 and 8 ARE NOT pythagorean triplets.
