Answer:
k = 0.167
Step-by-step explanation:
This is a direct proportion. That is as the number of chairs increases, so does the number of minutes needed.
y=number of chairs
x = time in minutes.
y = k x
4 = k * 24 Divide by 24
4/24 = k
You could leave it that way.
or you could do the division
k = 1/6 = 0.167
y = 0.167 x
Answer:
x=-1 y=4 (-1,4)
Step-by-step explanation:
Okay. In order to do this problem, you really need to condense it down to the hour. Since this is in months we want to find the hourly rate of pay. If you take her monthly salary and divide it by the monthly job hours, you are able to find the hourly rate of pay, which is $10 an hour.

Answer:
The population reaches 7 million people in the year 2032.
Step-by-step explanation:
We have that
Using this model, find the year when the population reaches 7 million people.
This is x years after 2000, in which x is found when f(x) = 7. So
We have to following logarithm rule
So we apply log to both sides of the equality
2000 + 32.66 = 2032
The population reaches 7 million people in the year 2032.
