The graph below shows the distance, y, that a car traveled in x hours:

Vika [28.1K]

This is a linear relationship as the rate of change is constant, ie constant velocity. And the slope represents the velocity, and slope is:

m=(y2-y1)/(x2-x1)

m=(50-25)/(2-1)=25/1

m=25

So the rate of change is 25 mph

Express the ratio in lowest form:<br>1.5 kg: 350 g

irakobra [83]

Given:

The ratio is:

1.5 kg : 350 g

To find:

The lowest or simplest form of the given ratio.

Solution:

We know that,

1 kg = 1000 g

We have,

1.5 kg : 350 g

It can be written as

$1.5\ kg : 350\ g=\dfrac{1.5\ kg}{350\ g}$

$1.5\ kg : 350\ g=\dfrac{1.5\times 1000\ g}{350\ g}$

$1.5\ kg : 350\ g=\dfrac{1500\ g}{350\ g}$

$1.5\ kg : 350\ g=\dfrac{150}{35}$

$1.5\ kg : 350\ g=\dfrac{30}{7}$

Therefore, the lowest form of the given ratio is 30:7.
