How many three-letter arrangements can be made from the letters in the word math?
The word "math" consists of 4 distinct letters: m, a, t, and h. To find the number of three-letter arrangements, we can use the permutation formula for selecting and arranging 3 letters from 4 distinct letters, which is given by ( P(n, r) = \frac{n!}{(n-r)!} ). Here, ( n = 4 ) and ( r = 3 ), so the calculation is ( P(4, 3) = \frac{4!}{(4-3)!} = \frac{4!}{1!} = 4 \times 3 \times 2 = 24 ). Thus, there are 24 different three-letter arrangements.

How many different 4-letter permutations can be formed from the letters in the word DECAGON?
The word "DECAGON" has 7 letters, with the letter "A" appearing once, "C" appearing once, "D" appearing once, "E" appearing once, "G" appearing once, "N" appearing once, and "O" appearing once. To find the number of different 4-letter permutations, we need to consider combinations of these letters. Since all letters are unique, the number of 4-letter permutations is calculated using the formula for permutations of n distinct objects taken r at a time: ( P(n, r) = \frac{n!}{(n-r)!} ). Here, ( n = 7 ) and ( r = 4 ), so the number of permutations is ( P(7, 4) = \frac{7!}{(7-4)!} = \frac{7!}{3!} = 7 \times 6 \times 5 \times 4 = 840 ). Thus, there are 840 different 4-letter permutations that can be formed from the letters in "DECAGON."
