explain why in a drawer only containing two different colors of socks one must pull 3 out to find a matching pair?

1 answer:

If there are only two colors (let's say blue and red), here's what can happen:
sock #1 is blue
#2 is either blue or red. If blue, it matches #1 and you have a pair.
if red, go to #3
#3-either blue or red. If blue, matches #1. If red, matches #2.

OR sock #1 is red... then just reverse the colors. Basically, if you have three things that can only be in two groups, then even if two of them are different, the last one has to match one of them.

Answer:

See explanation

Step-by-step explanation:

Let $(x,y)$ be the coordinates of the point which has to be dilated with the scale factor of $k$ with the center of dilation at point $(0,0)$ (the origin).

The dilation with the scale factor $k$ and the center of dilation at the origin has the rule

$(x,y)\rightarrow (kx,ky)$

So, you have simply to multiply each coordinate of the point by $k$ to get the image's coordinates.

Alexxx [7]

Let's use the relation:

$\mathsf{\dfrac{1}{x} = \dfrac{1}{5} + \dfrac{1}{7}}\\ \\ \\ \mathsf{\dfrac{1}{x} = \dfrac{7+5}{35}}\\ \\ \\ \mathsf{\dfrac{1}{x} = \dfrac{12}{35}}\\ \\ \\ \mathsf{x = \dfrac{35}{12}}\\ \\ \\ \boxed{\mathsf{x\approx 2.92 \ h}}$

It would take about 3 hours to complete the work.
