Assoli18 [71]3 years ago

Answer:

To multiply two fractions, we multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. However, we are taught that when faced with a problem such as 3⁄5 ÷ 4⁄7, we should invert the second fraction and multiply.

8. The scatter plot shows a hiker's elevation above
g100num [7]

Answer:

The hiker's elevation  after 145 minutes will be 1958 meters.

Step-by-step explanation:

The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).

Now, we have to predict the hiker's elevation after 145 minutes.

So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)

Federal Rent-a-Car is putting together a new fleet. It is considering package offers from three car manufacturers. Fred Motors i
Viefleur [7K]

Answer:

  • 40 packages from Fred Motors
  • 20 packages from Admiral Motors
  • 40 packages from Chrysalis

Step-by-step explanation:

I would formulate the problem like this. Let f, a, c represent the numbers of packages bought from Fred Motors, Admiral Motors, and Chrysalis, respectively. Then the function to minimize (in thousands) is …

  objective = 500f +400a +300c

The constraints on the numbers of cars purchased are …

  5f +5a +10c >= 700

  5f +10a +5c >= 600

  10f +5a +5c >= 700

Along with the usual f >=0, a>=0, c>=0. Of course, we want all these variables to be integers.

Any number of solvers are available in the Internet for systems like this. Shown in the attachments are the input and output of one of them.

The optimal purchase appears to be …

  • 40 packages from Fred Motors
  • 20 packages from Admiral Motors
  • 40 packages from Chrysalis

The total cost of these is $40 million.
