The alphabet of a fictionary tribe consists of three letters: A, O and M. Any combination of no more than four of these letters is considered a word. How many words are does this tribe's language have?

120 different words

Step-by-step explanation:

The max longest word has 4 letters

So the word can consist of 1 letter. The number of such wordds is 3 (A,O or M)

The word can consist also of 2 letters ( letters can be repeated in the word-

the word like AA or MM are possible). The number of such words is 3*3=9

The word can consist also of 3 letters ( letters can be repeated in the word-

the word like AMA or MMM are possible). The number of such words is 3*3*3=27

The word can consist also of 4 letters ( letters can be repeated in the word-

the word like or MAOM are possible). The number of such words is 3*3*3*3=81

So total number of words is 3+9+27+81=120

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
