Oil is pumped into a tank at a rate modeled by
R(t)= 3 cos (pi*t) + 5 measured in gallons/min. If there are
30 gallons in the tank when the pump starts and no oil is
being removed, how many gallons are in the tank after 102 seconds
seconds?

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

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:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
