Rachel drives at a constant speed of 70 miles per hour.

marishachu [46]

The linear function that models Rachel's distance as a function of time is:

D(x) = (70 mi/h)*x

<h3>How to find a function that models Rachel's distance as a function of time?</h3>

Remember the relation between speed and distance:

Distance = Speed*Time.

Here we know that the speed of Rachel is 70 miles per hour, then if she drives for x hours, the distance traveled will be:

D(x) = (70 mi/h)*x

So we found a linear function that models Rachel's distance as a function of time.

Answer:

18 tablespoons

Step By Step:

ratio is bananas/tablespoons
5 bananas/3 tablespoons
30 bananas/x tablespoons
how do we get from 5 to 30? multiply by 6. whatever we do to the top we do to the bottom, so multiply tablespoons but six as well

The Sun is roughly 10^2 times as wide as the Earth. The Star KW Sagittarii is roughly 10^5 times as wide as the Earth. About how

Studentka2010 [4]

Answer:

1000 times

Step-by-step explanation:

Given:

The Sun is roughly 10^2 times as wide as the Earth.

The Star KW Sagittarii is roughly 10^5 times as wide as the Earth.

Question asked:

About how many times as wide as the Sun is KW Sagittarii?

Solution:

Let the width of the earth = $x$

As the Sun is roughly 10^2 times as wide as the Earth, hence the width of the sun = $x\times10^{2}$

And as the Star KW Sagittarii is roughly 10^5 times as wide as the Earth, hence the width of the Star = $x\times10^{5}$

Now, to find that how many times width of the Star KW Sagittarii is as respect to the width of the Sun, we will simply divide:

Width of the Star KW Sagittarii = $x\times10^{5}$

Width of the Sun = $x\times10^{2}$

$\frac{x\times10^{5} }{x\times10^{2} }$

x canceled by x

$\frac{10^{5} }{10^{2} } =10^{5-2} =10^{3} =10\times\ 10\times10=1000$

Therefore, Star KW Sagittarii is 1000 times wider than Sun.

<em>First of all we calculated width of Sun in terms of width of earth and then calculated the width of the Star in terms of earth and for comparison we did simple division that showed that the Star KW Sagittarii is 1000 times wider than the Sun.</em>
