10000 digits can be used for 4 digit A.T.M code.
<u>Solution:</u>
Given that A.T.M required 4 digit codes using the digits 0 to 9.
Need to determine how many four digit code can be used.
We are assuming that number starting with 0 are also valid ATM codes that means 0789 , 0089 , 0006 and 0000 are also valid A.T.M codes.
Now we have four places to be filled by 0 to 9 that is 10 numbers
Also need to keep in mind that repetition is allowed in this case means if 9 is selected at thousands place than also it is available for hundreds, ones or tens place .
First digit can be selected in 10 ways that is from 0 to 9.
After selecting first digit, second digit can be selected in 10 ways that is 0 to 9 and same holds true for third and fourth digit.
So number of ways in which four digit number is created = 10 x 10 x 10 x 10 = 10000 ways
Hence 10000 digits can be used for 4 digit A.T.M code.

Answer: 24 in³
Step-by-step explanation:
You know that the dimensions of the box are:
3 inches.
4 inches.
2 inches.
As each face of the cardboard box is a rectangle, you can conclude that it has the form of a rectangular prism.
Therefore, to calculate the volume of the box, you must multiply the dimensions given in the problem.
Therefore, you obtain that the volume of the box is:
Answer:

Step-by-step explanation:
84 - 24 = 60
60 oranges were either ripe or unripe.
18 more ripe oranges than unripe oranges.
x + 18 = ripe oranges
x = unripe oranges
x + 18 + x = 60
2x + 18 = 60
2x = 42
x = 21
21 are unripe oranges
21 + 18 = 39
39 oranges are ripe.
Ratio of the number of ripe oranges to the number of rotten oranges to the number of unripe oranges.
39:24:21
13:8:7
