Answer:
Step-by-step explanation:
Pythagorean theorum: 5^2 +s^2 = 15^2 so 25 + s^2 =225
s^2 =200 so s = square root of 200 which is 10 times the square root of 2. So the first answer is right
6 blades in 1 windmill is the "unit rate" A unit rate is the number per thing. You will need to multiply. Multiply 6X7. 6 for 6 blades and 7 for 7 windmills. It is 42. 42 blades are in 7 windmills.
Using the Pythagorean theorem ~ a² + b² = c² ~, if this is true then the triangle is a right triangle.
a) 5² + 10² = 15²
25 + 100 = 225 *FALSE*
b) 13² + 35² = 37²
169 + 1225 = 1369 *FALSE*
c) 9² + 40² = 41²
81 + 1600 = 1681 *TRUE*
d) 6² + 9² = 10²
36 + 81 = 100 *FALSE*
The answer is C) 9, 40, 41.
