You have 458 pennies in a jar. calculate the number of dollars, quarters, dimes, nickels, and pennies you should get when you take the money to the bank. (the bank will give you the fewest coins possible.) print out the number of dollars, quarters, dimes, nickels, and pennies you will get from the bank. print out the total number of coins you will get. (is a dollar bill a coin? )

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
