The number of months after which amount paid to two fitness clubs be the same is 10
Step-by-step explanation:
Given as :
The charge of Mikes fitness center = $30 per month fro membership
The charge of All-Day fitness center= $22 per month fro membership + $80
initiation charge
Let The number of months after which amount paid to each club be same = x
So, According to question :
30 x = 22 x + 80
Or, 30 x - 22 x = 80
Or, 8 x = 80
So x =
∴ x = 10
Hence The number of months after which amount paid to two fitness clubs be the same is 10 Answer
648 is the three-digit positive integers have three different digits
According to the statement
we have given that there are three positive digit number are formed with three distinct digits.
And we have to find that the how many words are formed with distinct numbers.
So, to solve this type of problem the Combination formula is best.
Because it provides the all possibilities that from how many ways numbers are formed.
So, from a combination formula
here we take 9 two times because first time when we let a number then remaining numbers are 9. and second time remaining numbers are also 9 because we let the distinct number but for third number there will be a probability that choosing number will be same.
So, Three digit positive number become from 9*9*8 =648
So, 648 is the three-digit positive integers have three different digits.
