Explain why in a drawer containing only two different colors of socks one must draw only three socks to find a matching pair.

In the drawer you have a total of 4 socks: the one you already have, two of a different color and one of the same color of the first sock. If the first two socks you draw are of a different color, the third one will surely be of the color of the first sock.

There are two different colors of socks, so in the worst case scenario you can draw two different socks. Therefore you need to draw one more sock of any color to have a matching pair.

2+1=3 :)

On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawn

Mowing 4 lawns in 6 hours gives a mowing rate of 6/4 = 1.5 hours per lawn.
To mow 9 lawns, you need 1.5*9 = 13.5 hours.

6. Write the equation of the line.

liberstina [14]

Answer:

y = x + 2

Step-by-step explanation:

As the equation of a line is in the form y = mx + c:

Step 1 - Calculate the y intercept

This can be done by looking at the y coordinate where x = 0:

y = mx + c

In the picture, the y intercept is 2 so:

y = mx + 2

Step 2 - Calculate the slope

This can be calculated by:

$\frac{\text{change in y}}{\text{change in x}}$

Get two sets of coordinates:

(0, 2) and (2, 4)

Calculate the changes by subtracting from one another:

$\frac{4 - 2}{2 - 0} \\\frac{2}{2}\\=1$

So the gradient is 1, meaning the equation of the line is:

$y = 1x + 2 \\\text{or}\\y = x + 2$

Hope this helps!

Explain your answer so I can understand

If all the sides equal(1.2mi and he’s riding on all sides) then he would have to ride his path 6.25 times because 30 divided by 4.8 is 6.25 if he’s only riding on one side then he would ride his path 25 times because 30 divided by 1.2 is 25
