Answer:
2100
Step-by-step explanation:
There are 21 consonants that can serve as the first and last letters. There are 5 vowels that can serve as the 2nd and 4th letters. There are 20 remaining consonants that can serve as the 3rd letter. (The same consonant cannot appear in all three places.)
So, the total number of 5-letter palindromes that start with a consonant and alternate with a vowel will be ...
21×5×20 = 2100 . . . different palindromes
There are two variables here, which are time (minutes) and the number of beats, and they both have a relationship (68 beats in one minute), therefore it is an example of a unit rate
Here ... I'll give you all the help you need to answer this question
on your own:
-- The three angles inside any triangle always add up to exactly 180 degrees.
-- Simply examine each group of numbers in the question.
Any set that adds up to 180 can be the three angles of a triangle.
Any set that doesn't, can't.
