How many different 10-letter permutations can be formed from 8 identical H's and two identical T's?

melamori03 [73]

Answer:

<h3>45 different permutations</h3>

Step-by-step explanation:

Given 10 letters with 8 identical H's and two identical T's, the number of different permutations will be expressed as;

$= \dfrac{10!}{8!2!}$

$= \dfrac{10*9*8!}{8!*2!}\\ \\= \dfrac{10*9}{2*1}\\ \\= \dfrac{90}{2}\\ \\= 45$

<em>Hence the number of different 10-letter permutations that can be formed from 8 identical H's and two identical T's is 45</em>

In an ordered pair,the x-coordinate represents the number of hexagons and the y-coordinate represents the total number of sides.

Novosadov [1.4K]

The y-coordinate would be 42.

Hexagons have 6 sides. The x-coordinate is the number of hexagons; since our x-coordinate is 7, that means 7 hexagons.

The y-coordinate is the total number of sides. 7 hexagons * 6 sides per hexagon = 42 sides.
