A supervisor must split 60 hours of overtime between five people. One employee must be assigned twice the number of hours as eac
insens350 [35]

Answer:

A. 10 hours for 4 employees and 20 hours for 1 employee.

Step-by-step explanation:

Okay, let's get to it! :D

So first, we need to set up an equation.

We know there are 60 total hours split between 5 people, and we can assign the number of hours 4 of the employees get as x. We also know that one employee gets double the amount of hours, so they would get 2x. Now, let's put that into an equation :)

60 = 2x + 4x

Now we add the x's together so the equation looks like this:

60 = 6x

To find x, we have to get it alone, so now we divide 60 by 6.

X = 10

But we're not done yet. X is the amount the 4 employees have to work, but because one employee has double the hours, we double our x-value to get 20 hours for that one employee.

Use the fact that the world population was 2560 million in 1950 and 3040 million in 1960 to model the population of the world in
Radda [10]

Answer:

Let the growth function that shows the population in millions after x years,

P=P_0(1+r)^x

Where,

P_0 = initial population,

r = growth rate per year,

Suppose the population is estimated since 1950,

Thus, if x = 0, P = 2560,

\implies 2560 = P_0 (1+r)^0\implies P_0 = 2560

Now, if x = 10 ( that is, on 1960 ), P = 3040,

3040=2560(1+r)^{10}\implies r = 0.017

Hence, the required function that shows the population after x years,

P=2560(1.017)^x

If x = 42,

The population in 1992  would be,

P=2560(1.017)^{42}\approx 5196.608365\text{ millions}

if x = 80,

The population in 2030 would be,

P=2560(1.017)^{80}\approx 9860.891929\text{ millions}

How long will it take the train to travel 350 miles at this speed?
poizon [28]

If the speed is expressed in (miles per hour),
then it will take the train exactly

                   <em>(350) divided by (speed)  </em>          hours

to travel 350 miles at that speed.
