Mark is saving his money to buy a new bike, which costs $500. He has already saved $50. He earns $60 per week mowing lawns and wonders how many weeks it will take to earn enough for the bike. Make a table showing the week number, W, and total savings, in dollars, S, in Mark’s savings account. Use the table you make to answer the questions. How much will he have saved at 12 weeks?

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

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 %
