Divide 900/150 to find the amount of money paid, since 1.00 is paid for every 150 pieces.
900/150=6
The answer is 6.00.
In this problem, volume is computed:
volume = ∫(flow rate)·dt
.. = ∫[0, t] (3/10)*sin(2πt/7)·dt
= (3 / 10)*(7 /(2 π))*(-cos (2 π t/7)+1)
= (-21 / (20 π))*(cos (2 π t /7) - 1)
Volume is equal to 21 sin^2 (pit/7) / 10pi is the inhaled air in the lungs at time t
You're just dividing in this problem
which if you divide both bottom and to portion by 3 it leads to
4/3
