<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.
Your computer will programs more slowly, when you go to an anti-virus software, for some, it will block you from allowing you to access the application. Your information may be stripped from your computer, allowing the infection to take your personal identity and money.
Answer:
The codes below implement the problem statements
Explanation:
public class Percentages {
public static void computePercent (int a,int b)
{
System.out.println(a+" is "+(a*100/b)+"% of "+b);
}
public static void main(String []args)
{
int a=2;
int b=5;
computePercent(a,b);
computePercent(b,a);
}
}
<u>
</u>
<u>Part(b)
</u>
import java.util.*;
public class Percentages {
public static void computePercent (int a,int b)
{
System.out.println(a+" is "+(a*100/b)+"% of "+b);
}
public static void main(String []args)
{
Scanner s= new Scanner(System.in);
int a=s.nextInt();
int b=s.nextInt();
computePercent(a,b);
computePercent(b,a);
}
}
