Mr delaney broke his piggy bank with a sledge hammer and found that it only contained quarters and pennies. If he had a total of 120 coins for a combined value of $16.32 , how many pennies did he have in the piggy bank?

57

Step-by-step explanation:

You do 1575 divided by 25 and you find 63 (quarters). Then you do 1632-1575 and you find 57 and then 57+63= 120 coins.

- "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."

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
