Right triangle, Pythagorean Theorem:
c² = a² + b²
a=8, b=9
c² = 8² + 9² = 64 + 81 = 145
c = √145 inches
That's the exact answer but they want us to ruin it with an approximation.
c ≈ 12.041594578792296 inches
Answer: 12

Rectangle. I hope this helps.
Qty · % = Total
Drink 1: x .25 = .25x
Drink 2: 15 - x .10 = .10(15 - x)
Mixture: 15 .21 = .25x + .10(15 - x)
(15)(.21) = .25x + 1.5 - .10x
3.15 = .15x + 1.5
1.65 = .15x
11 = x
Drink 1 (25%) is 11 liters
Drink 2 (10%) is 15 - 11 = 4 liters
