Rob built a sandbox in the shape of a right triangle. If one leg is 5 feet and the other leg is 7 feet, how long is the hypotenuse of the sandbox?

Step-by-step explanation:

use pythagoras’ theorem

square of hypotenuse = square of adjacent + square of opposite

h^2 = 5^2 + 7^2

h^2 = 25 + 49

h^2 = 74

h = square root of 74

h = 8.6 feet

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
