<span>A has earned twice as much as B so: A=2B
B has averaged 50% more than C so: B=C+0.5C
Combined is 220K, So A+B+C=220,000
The last equation can be re-written as:
2B+1.5C+C=220K
AND since A=2B, it can be rewritten again as:
3C+1.5C+C=220K
Now you can get C
finally, since B=1.5C you can get B, then to get the average, just divide that by 3 (years) and you should be done.
So B = 60000 for 3 years</span>
3h
The set cost is 25, because c=25 when h=0. So, this leaves 3h as the hourly rate.
Hello the answer is on the paper
Answer:
1km per minute
Step-by-step explanation:
Given the table in the picture :
The average rate of change over the interval from 8 to 15 minutes will be :
Change in distance / change in time
Change in distance between 8 and 15 minutes :
Distance d1 at 8 minutes t1 = 7km
Distance d2 at 15 minutes t2 = 14km
Average rate of change = (d2 - d1) / (t2 - t1)
Average rate of change = (14 - 7)km / (15 - 8)min
Average rate of change = 7km / 7minutes
Average rate of change = 1km per minute
Two fields at a state park are 1,000 meters from each other. On a map, the two field are 8 centimeters apart. What scale is the map using?
Answer:
Step-by-step explanation:
Given
two fields are 1000 meters from each other on a map, and the two fields are 8cm apart.
We have to express the scale of the map as unit of measure. So we need to figure out how many actual meters for each cm in the map.
If 1000 meters is equal to 8 cm, how many meters (let's calls this x) is equal to 1 cm?
Therefore, the scale is
