Answer:
import java.util.Scanner;
public class WeeklySalary {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter Hourly wage");
double hourlyWage = in.nextDouble();
System.out.println("Enter total hours worked in the week");
int hoursWorked = in.nextInt();
int overtime = hoursWorked - 40;
double weeklyWage = 40*hourlyWage;
System.out.println("Total Over Time Hours is: "+overtime);
double overTimeWage = overtime*(hourlyWage*1.5);
System.out.println("Wage for full time: "+ weeklyWage);
System.out.println("Wage for over time: "+ overTimeWage);
}
}
Explanation:
- Using Java programming language
- Import the Scanner class to receive user input
- prompt user for hourly wage rate, receive and save in a variable
- Prompt user for total hours worked for the week receive and save in a variable
- calculate overtime hours by subtracting 4 from total hours worked in the week
- Calculate weekly wage by multiplying hourly rate by 40
- Calculate overtime by multiplying overtime hours by (hourlyWage*1.5).
- See attached sample run of the code
Answer:
Hi!
The correct answer is the a.
Explanation:
The Moore's law is an a empirical law that Gordon Moore predicted doing some observations about how the density of the transistors on a integrated circuit was increasing over time.
For example, this law state that if you have an integrated circuit with: 1000 transistors in 1980 then in 1981 and six months later you will have the same integrated circuit with 2000 transistors, and so on..
- Jan 1980: 1000 transistors.
- Jul 1981: 2000 transistors.
- Jan 1983: 4000 transistors.
- Jul 1984: 8000 transistors.
And that's the reason because its cost will fall too.
In a real-world environment, changing granularity requirements might dictate changes in primary key selection, and those changes might ultimately require the use of surrogate keys.
Explanation:
A surrogate key is a unique identity as an object or entity. It is used as an object in the database and as an entity in the modern world. Surrogate key is not a natural key hence it cannot be derived from application data.
Advantages of using surrogate key:
- They are unique
- They have uniform rules
- It allows unlimited values
- It stands the test of time
A.Needs since they are necessary and needed for survival
