Mathematics

Answer:

13 hours and 20 minutes

Step-by-step explanation:

Joan read in 4 hours = 75 pages

She read in 1 hour = \frac{75}{4} pages

                               = 18.75 pages

It will take her to read 250 pages = \frac{250}{18.75}

                                                        = 13.33 hours.

Now we will convert 0.33 hours to minute.

0.33 × 60 = 19.8 minutes  ≈ 20 minutes

It will take her 13 hours and 20 minutes to read 250 pages.

75/4=25 pages per hour, so, now we have to divide 250 by 25.

250/25=10

So, it would take Joan 10 hours to read 250 pages. :)

Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's s
alukav5142 [94]

Answer:

The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km

Step-by-step explanation:

The given parameters from the question are;

The elevation of the meteor above the Earth's surface = 100 km

The rate at which the meteor falls = 20 km per second

The 'x' values represent the time in seconds and the 'y' values represent the meteor's height

Therefore, we have;

y = 100 - 20·x

The domain of a function is the set of inputs to the function

Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface

At the start x = 0 seconds

On the Earth's surface, y = 0, therefore;

0 = 100 - 20·x

x = 100/20 = 5

When the meteor just touches the Earth's surface x = 5 seconds

Therefore, the domain is 0 ≤ x ≤ 5.
