It is a permutation problem (any number can be used repeatedly), it will become 4 x 4 x 4 x 4 = 256 four digit numbers. If each number can only be used once, then the answer is 4 x 3 x 2 x 1 = 24 four digit numbers.

-99

The answer depends on how long the PIN string is. With a ten digit string, where a leading zero is permitted, the answer is 3628800.With only 4 digits, and with leading zero permitted, the answer is 5040.

If you get 23 mpg, that means that for every gallon of gas, you travel 23 miles. Simply divide the number of miles travelled by the number of miles you travel per gallon of gas. In this case, 10000 miles / 23 mpg = 434.8 gallons.

Three digits.

Permutation means one of several possible outcomes or considerations. it tends to be used when deciding whether to change arrangements and what the subsequent effects could be.

If every number can be used as many times as you like, there are 104 = 10000 different combinations. If each number can only be used once, there are 9!/(9 - 4)! = 5040 combinations.

They are called combination locks because that is the general, conventional term used. Trying to call them permutation locks is mixing different areas of usage together and that is not valid.

One Joule is one Newton-Meter, (Joule = Newton times Meter), so 10000 Joule equals 10 Newton-Kilometers (N*km). 10000*J/N = 10 kmAnswerYou might as well be asking how many millimetres there are in kilowatt! Your question is meaningless! A kilometre is used to measure length, whereas the joule is used to measure energy. The original answer is nonsense.

If we throw 1000000 out of our calculations (this is okay because it doesn't have any nines in it) then we're left with all the numbers with 6 or less digits. There are 10 choices for each digit. If the 100000's digit is 9, then there are 105=10000 ways to choose the remaining digits, so there are 10000 numbers that have 9 in the 100000s place. Similarly, there are 10000 numbers that have 9 in the 10000s place, 10000 numbers with 9 in the 1000s place, and so on. There are 6 different places 9 could be in, so the digit 9 is used 10000*6 or 60000 times. Improved... well your missing a zero in your answer.... the total amount of 9's used should be 600 000 , not 60 000 because already in the hundred thousands digit 9 is being used 100 000 times becasue from 900 000- 999 999, the number nine is being used atleast 100 000 times so already your answer is wrong. And if you did you method corectly, it should be the same for every other digit, which means the answer will be that 9 will appear 600 000 times between 1 and 1 000 000. Correct me if im wrong, but im pretty sure that that is the answer. (sources):http://www.cemc.uwaterloo.ca/contests/past_contests/2008/2008GaussSolution.pdf (question 25)
