Use a calculator to perform each division.APPLICATIONS
Use signed numbers to solve each problem.- LOWERING PRICES A furniture store owner
reduced the price of an oak table an equal amount
each week, because it was not selling. After six
weeks, and a $210 reduction in price, the table was
purchased. By how much was the price of the table
reduced each week? - TEMPERATURE DROP During a five-hour
period, the temperature steadily dropped 20°F.
By how many degrees did the temperature change
each hour? - SUBMARINES In a series of three equal dives,
a submarine is programmed to reach a depth of
3,030 feet below the ocean surface. What signed
number describes how deep each of the dives
will be? - GRAND CANYON A mule train is to travel from
a stable on the rim of the Grand Canyon to a camp
on the canyon floor, approximately 5,500 feet below
the rim. If the guide wants the mules to be rested
after every 500 feet of descent, how many stops will
be made on the trip?
