Over the last 3 years, salesperson A has earned twice as much as salesper B who in turn has averaged 50% more than salesper C. T
bekas [8.4K]
<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>

ankoles [38]

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 on 1000 from each other on a map to to filter 8 cm apart what scale is a map using​
Soloha48 [4]

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:

1 cm: 125m

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?

\frac{1000}{8} =\frac{x}{1}

x=\frac{1000\times 1}{8} \\x=125

Therefore, the scale is 1 cm: 125m
