Au. s. postal service supervisor is looking for ways to reduce stress in the sorting department. with the existing arrangement, stamped letters are machine-canceled and loaded into tubs with 325 letters per tub. the tubs are then pushed to postal clerks, who read and key zip codes into an automated sorting machine at the rate of one tub per 250 seconds. to overcome the stress caused when the stamp canceling machine outpaces the sorting clerks, a pull system is proposed. when the clerks are ready to process another tub of mail, they will pull the tub from the canceling machine area. how many tubs should circulate between the sorting clerks and the canceling machine if 110 comma 000 letters are to be sorted during a 9-hour shift, the safety stock policy variable, alpha, is 0.15, and the average waiting time plus material handling time is 15 minutes per tub?

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
