0.20(150) = 30 basketballs were in the shipment. Since the shipment presumably comprised only footballs and basketballs, the remainder of the shipment must consist of footballs.
150 - 30 = 120 footballs were in the shipment.
Ok so
The answer would be the second one (3+3+3+3=3 (4) )
Here's the explanation
It doesn't belong there because all the rest have to do with exponents
And that problem does not
Also,that problem uses repetitive addition while the other ones use repetitive multiplication
Hope this helps :)
Answer:
Yes! This is a right triangle.
Step-by-step explanation:
To solve this problem, you need to use the Pythagorean Theorem, which is: 
. In this equation, "A" represents the smallest length, "B" represents the next smallest length, and "C" represents the largest length. If a triangle is a right triangle, then the A squared + B squared equals C squared.
In this equation:
A = 12
B = 16
C = 20
1. Insert the values: 
2. Simplify: 
, and 
, so this is a right triangle.
