Answer: If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
1/5 is the simplest form of the fraction
<span>There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. We calculate as follows:
Molarity = 78.6 g KF ( 1 mol / 58.1 g ) / .225 L = 6.013 mol / L KF solution</span>
So it is 1.75 feet per second and you go 280 feet.
You would do 280/1.75=x
x=160
It will take you 160 seconds to go 280 feet
It takes 160 seconds
