Answer:

5/24

Step-by-step explanation:

5 white

3 black

1 red

total number of pairs of socks: 5 + 3 + 1 = 9

On Monday there are 9 pairs. 3 pairs are black.

On Tuesday, one pair of black socks is already taken, so there are now 8 pairs of socks. 5 of those are white.

p(black on Mon. & white on Tue.) = 3/9 * 5/8 = 1/3 * 5/8 = 5/24

Black socks on monday - 3/9 or .33%.
white socks on tuesday - 5/9 or .55%

Explanation: Probability of black socks on Monday:
Total pair of socks: 1 + 3 + 5 = 9
Number of black socks on Monday: 3
3/9 = 1/3 (or divide to get a percentage)

Probability of white socks on Tuesday:
Total pair of socks: 9
Number of white socks on Tuesday: 5
5/9

How do you find scale factor

Lerok [7]

First, a scale factor is the ratio of the corresponding sides in two similar geometric figures.

To find the scale factor:
1. Locate two corresponding sides (one on each figure).
2. Write the ratio of one length to the other.
And there you go! That's the scale figure from one figure to the other

Hope that helps and correct me if I'm wrong!

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

Anettt [7]

Answer:

d = 13.8 feet

Step-by-step explanation:

Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder. That formula is

$V=\pi r^2h$

We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet. Filling in then gives us:

$6000=(3.141592654)(r^2)(40)$

Simplify on the right to get

$6000=125.6637061r^2$

Divide both sides by 125.6637061 to get that

$r^2=47.74648294$

Taking the square root of both sides gives you

r = 6.90988299

But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8
