<em><u>Answer</u></em>
5 hours
<em><u>Explanation</u></em>
The two working together can finish a job in
Also, working alone, one machine would take one hour longer than the other to complete the same job.
Let the slower machine working alone take x hours. Then the faster machine takes x-1 hours to complete the same task working alone.
Their combined rate in terms of x is
This should be equal to 20/9 hours.
Multiply through by;
Factor to get:
It is not feasible for the slower machine to complete the work alone in 4/9 hours if the two will finish in 20/9 hours.
Therefore the slower finish in 5 hours.
The statement that completes the query is: bytes / 1000 AS kilobytes
<h3>SQL (Structured Query Language)</h3>
This is the language that is used to retrieve, update, and store data in the database.
<h3>Columns</h3>
From the question, we have the following table columns
- track_id
- track_name (name of the music track)
- composer
- bytes (digital storage size of the music track
To retrieve data from the bytes column, we make use of:
SELECT bytes ......
From the question, we understand that this column should be divided by 1000, and the AS command should be used.
So, the query becomes
SELECT bytes / 1000 AS kilobytes .....
Hence, the statement that completes the query is: bytes / 1000 AS kilobytes

Answer:
It is either an internal IP address or it is a private IP address.
Explanation:
Answer:
When a programmer tries to access an item in an array cell whose index is greater than or equal to the array's logical size, this data element or item is garbage. This means that currently, the item is not the part of the program's useful data. Garbage contains objects or data which will not be used by a program running on it. So the value returned could be either of the two:
- Value would be an arbitrary or random number if it is an array of numbers. Arbitrary means that the value is not predefined or specified in advance.
- Value returned would be null if it is an array of objects.
