What is the 16-bit hexadecimal representation of each of the following signed decimal integers?
Reil [10]

Answer:

FFE3

Explanation:

The 16 bit binary representation of 29 = 0000000000011101

The corresponding hexadecimal representation = 001D

Taking 2s complement, the binary representation of -29:

Step 1 : 1's complement of 29 = 1111111111100010

Step 2 : Adding 1 to 1's complement to get the 2's complement => 1111111111100010 + 1

= 1111111111100011

Converting the binary representation to equivalent hexadecimal format: FFE3

jeka94

Answer:

import java.util.Scanner;

public class MoveEstimator

{

public static void main(String[] args) {

   

    Scanner input = new Scanner(System.in);

    final int BASE_RATE = 200, RATE_PER_HOUR = 150, RATE_PER_MILE = 2;

    int hours, miles;

    double totalFee = 0.0;

   

 System.out.print("Enter the number of hours for a job: ");

 hours = input.nextInt();

 System.out.print("Enter the number of miles: ");

 miles = input.nextInt();

 

 totalFee = BASE_RATE + (hours * RATE_PER_HOUR) + (miles * RATE_PER_MILE);

 System.out.printf("For a move taking %d hours and going %d miles the estimate is $%.2f", hours, miles, totalFee);

}

}

Explanation:

*The code is in Java.

Create the Scanner object to be able to get input

Initialize the constant values using final keyword, BASE_RATE, RATE_PER_HOUR, RATE_PER_MILE

Declare the variables, hours, miles, totalFee

Ask the user to enter the hours and miles

Calculate the totalFee, add BASE_RATE, multiplication of  hours and RATE_PER_HOUR, multiplication of  miles and RATE_PER_MILE

Print the output as in required format
