How many 6-digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, if repetitions of digits are allowed?

There are 6 digits. Each digit can take ten different numbers except for the first digit since it cannot be zero.
So:
9 x 10 x 10 x 10 x 10 x 10
900000 numbers.
Another way of thinking about this is to just count up to 999,999. Obviously there are 999,999 different numbers here. But since our number has to have 6 digits in them, we have to delete 99,999 numbers. Thus there are 900,000 different numbers.
Answer:
If the packages are the same size and everything and has the same volume, then it would be 1/6 more of a package.
Step-by-step explanation:
1/6
1/6
1/6
1/3 is equal to 2/6 because you can multiply the numerator (the top) and the denominator (the bottom number in a fraction) by 2 to get 2/6. The pepperoni usage of the package was 2/6, while the sausage was 1/6.
2/6 minus (-) 1/6 is equal to 1/6.
Make a proportion to find the percent:
25/64 = x/100
Multiply 25 and 100, then divide that answer by 64. Then add a percent symbol.
25*100 =2500
2500/64 = 39.0625
39.0625%
Answer:
if you don't have to simplify it, it is
Step-by-step explanation:
the equation for the area of a square is
substitute 72 for a
take the square root of both sides to cancel out the square on the s
if you need it simplified, find the perfect square that makes up 72. It is 36.
take the square root of 36
