There are 4 letters in a bag: S, O, P, and T. In how many ways can these letters be drawn out? A.4
B.12
C.24
D.120

B

Step-by-step explanation:

Because all of these letters are distinct, the total number of ways to draw them is 4!, or 24.

Another way you can do this is by discerning the number of ways the individual numbers can be drawn. In the beginning, there are 4 letters to pick. If you pick a letter out, you now have 3 letters to pick. If you pick a letter out, you now have 2 letters to pick. After, you only have 1 letter to pick. 4 * 3 * 2 * 1 = 24.

C

Step-by-step explanation:

I think it's C, 4 * 3 * 2 * 1 = 24

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
