Find three right triangles based upon the Pythagorean Triple of 8, 15, and 17. Explain how you know these are triangles.

Luba_88 [7]

A^2 + b^2 = c^2
8^2 + 15^2 = 17^2
64 + 225 = 289
289=289
It is a triangle because the numbers match the Pythagorean Theorem.

Cheyenne ran a 6.36-kilometer race in 53 minutes. What was her speed in kilometers per hour?

svlad2 [7]

Answer:

7.23km/h

Step-by-step explanation:

Speed = distance/time

Given

distance = 6.36km and

Time = 53minutes

Convert 53minutes to hour.

60 minutes = 1 hour

53 minutes = x hour

Cross multiply

X hour x 60 = 53

Xhour = 53/60

X = 0.88 hour

Therefore

Speed = 6.36km /0.88hr

= 7.23km/h
