In 1989, Dutch ice skater Dries van Wijhe skated 200 km at an average speed of 35.27 km/h. How long was he skating? Use the formula d = rt, where d is the distance in km, r is the rate in km/h, and t is the time in hours. How long would it take to earn $6,000 in interest on a principal of $9,000 at an annual simple interest rate of 4.1%? Use the simple interest formula I = prt, where I is the interest earned, p is the principal, r is the interest rate per year, and t is the time in years.

step-by-step explanation:

their are no angles. sorry cant .

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 %

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
