(If gets it right get's brainliest)If the hypotenuse of an isosceles right triangle is 14, what is the area of the triangle?

Strike441 [17]

Answer:

49 unit²

Step-by-step explanation:

Right triangle with equal legs given, let the leg be x.

Hypotenuse of isosceles right triangle is

√x² + x² = x√2

Area of triangle:

1/2ah= 1/2x²

Since we have hypotenuse = 14 units:

x√2=14
x= 14/√2

Then area:

1/2x² = 1/2*(14/√2)² = 1/2*14²/2 = 7² = 49 unit²

A giraffe can run 32 miles per hour. What is the speed in feet per second? (1 mile = 5280 ft)

velikii [3]

Set up your conversion using dimensional analysis. That's just a fancy way of saying set up your values so you cancel what you don't need and keep what you do. If we want to convert miles per hour to feet per second, we need to convert the miles to feet using the fact that there are 5280 feet in 1 mile, and then convert the hours to seconds using the fact that there are 3600 seconds in an hour. Your set up will look like this (it's all about setting up the fractions correctly): $\frac{32miles}{hour}*\frac{5280feet}{1mile}*\frac{1hour}{3600seconds}$ . If you look at that closely, you can see the there is a label of miles on the top in the first fraction and on the bottom in the second fraction. Those cancel each other out by reducing. Then in the bottom of the first fraction there is hours and in the top of the last fraction there is hours. Those cancel out. From top to bottom or bottom to top you can cancel like labels. This leaves us with feet in the top and seconds in the bottom. Now it's a matter of doing the math. You multiply straight across the top and straight across the bottom. $\frac{168960feet}{3600seconds}$ . Simplifying you get 46.933 feet per second.
