2. students are selling raffle tickets for a school fundraiser, they collect 524 for every 10
raffle tickets they sell.
a, suppose m is the amount of money the students collect for selling r raffle
tickets, write an equation that reflects the relationship between m and r.

y=24/10  R=12/5

Step-by-step explanation:

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
