61

Step-by-step explanation:

Rectangle area=

The area at the right

Total area = 2400+628=3028yd^2

Now you have to find the quantity of grass seed needed (1pound for every 50yd square)

3028/50=60.56 (which is almost 61)

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

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 %
