<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.
<span>If a user name can have seven letters (with no distinction between upper and lower case), and if a letter can be repeated, then the maximum number of names is 26x26x26x26x26x26x26, or 8,031,810,176. That is, slightly more than eight billion names are possible.</span>
Answer:
See the code snippet below
Explanation:
import java.util.Scanner;
public class LabProgram{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Please enter first number: ");
int firstNumber = scan.nextInt();
System.out.println("Please enter second number: ");
int secondNumber = scan.nextInt();
maxMagnitude(firstNumber, secondNumber);
}
public static int maxMagnitude(int firstValue, secondValue){
System.out.println(Math.max(firstValue, secondValue));
}
}
