Answer:
5, 10 and 16
Explanation:
The sum of their ages is √961 = 31
If Joe is x years old, the equation that follows is:
x + (x+5) + (x+5+6) = 31
This simplifies to
3x = 31 - 11 - 5 = 15
so x=5
From that you can find
Joe = x = 5
Kate = x+5 = 10
Jody = x+5+6 = 16
I'm going to assume this is Java, because you said "method" meaning it will be some sort of object oriented language, and Java's really common. Here would be the full program, but you can just take the method out isolated if you need it.
package lastname;
public class LastName {
public static void main(String[] args) {
// Example usage:
String name = LastName.lastName("Garrett Acord");
System.out.println(name);
// Output: Acord G.
}
public static String lastName(String fullName)
{
String[] splitName = fullName.split(" ");
return String.format("%s %s.", splitName[1], splitName[0].substring(0,1) );
}
}
Answer:
sum, price, count
Explanation:
Programmers should use significant names for the variables.
Not only it makes it easier for them to remember what kind of information is stored in each variable, but it also makes life simpler for anyone who would read the code later.
Names like sum, price and count are significant names ( assuming they actually hold this kind of data), and will make the re-reading of the program code much easier.
