Find a common multiplier then divide ex. 21/27 = 7/9
This can be converted to 175%
Answer:
The total number of combinations is 2,358,720,000
Step-by-step explanation:
For the letter part of the ID we have 3 letters out of a space of 26 possible letters (a-z), and they can't repeat. For the number part we want to group 5 numbers out of 10 possible algarisms (0-9).So we can make an arrangement for the letters and one for the numbers and multiply them. The arrangment can be done using the following formula:
A(n,k) = (n!)/(n-k)!
Where n is the total number of possibilities and k is the size of the group.
For the letters:
A(26,3) = (26!)/(26-3)! = (26!)/(23!) = (26*25*24*23!)/(23!) = 26*25*24 = 15600
For the numbers:
A(10,5) = (10!)/(10 - 5)! = 10!/5! = (10*9*8*7*6*5!)/(5!) = 10*9*8*7*6*5 = 151200
The total number of combinations is the product of both, so:
combinations = 15600*151200 = 2,358,720,000
The real question is: If <em>you</em> need to divide 0.054 by 0.72 , how do <em>you</em> do it ?
If you learned long division in school, then you do it with a pencil and paper. You set up the numbers in a certain way, you put the decimal point where it belongs, and you crank through it. All of that is your work, and if you just hand in that piece of paper, then it shows your work.
If you never learned long division, or you learned it and forgot how to do it, and you do all of your division problems with a calculator, and if there's no calculator available then you haven't got a clue, well then there's really no way to show your work. I guess you could take a video of yourself pushing the buttons on the calculator, and then reading off the answer and copying it onto the homework sheet. But for a problem that says "Show your work", I feel like that would not fly.
(30m/s divided by 2)x 10800 ( convert 3hr to seconds by x with 60squared)
= 162000 m ( convert m to km by dividing with 1000)
= 162 km
