Is 45m, 36m, 27m a right triangle

Yes

Step-by-step explanation:

This is what I think:

This is because the hypotenuse of the triangle is 45m.

27 ^2 + 36 ^2 = 2025

2025 SQAURE ROOT IS 45.

So the square root of the two other measurements squared must be equal to the hypotenuse.

2.7 miles = x

Step-by-step explanation:

Given  : Lorinda can walk 1.8 miles in 30 minutes.

To find : Which proportion can be used to find how many miles she can walk in 45 minutes.

Solution : We have given  Lorinda can walk 1.8 miles in 30 minutes.

Let Lorinda can walk in 45 mintute = x.

=.

This is the direct Proportion.  

0.06 *45  = x

2.7 miles = x

Therefore, 2.7 miles = x
