Answer:

The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops

Explanation:

An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'

A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.

D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.

Jessie will make and sell the trending Baked California Maki. Her Peso mark up is 5.00. Selling price PHP 15.000. How much will

Levart [38]

Answer:

50%

Explanation:

The markup is the difference between the selling price and the cost price. If the mark up is greater than zero, it means there is a profit, if the markup is less than 0, it means there is a loss and if the markup is equal to 0, it means there is breakeven.

Percentage markup = (markup/cost price) * 100%

Selling price - cost price = markup

15 - cost price = 5

cost price = 10

Percentage markup = (markup/cost price) * 100% = (5/10) * 100% = 50%

Describe the Order of Operations in Java programming.

cestrela7 [59]

Answer:

It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. PEMDAS is often expanded to the mnemonic "Please Excuse My Dear Aunt Sally" in schools. Canada and New Zealand use BEDMAS, standing for Brackets, Exponents, Division/Multiplication, Addition/Subtraction.

Write the definition of a method, isReverse, whose two parameters are arrays of integers of equal size. The method returns true

Marat540 [252]

Answer:

public static boolean isReverse(int [ ]a, int [ ]b ){

for (int i=0;i<a.length;i++)

{

if(!(a[i] == b[a.length-i-1]))

return false;

}

return true;

}

Explanation:

Using a for loop, we go through the elements of the first array. The if comapres and checks if any of the values are not the same as the appropriate value on the other array, if it is so, then it is not a reverse, and we return false. else we return true.

Read one positive integer n. Then create an n X n two-dimensional array and write the code that stores integers from 1 to n2 as

marysya [2.9K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int n;

Scanner input = new Scanner(System.in);

System.out.print("Size of array: ");

n = input.nextInt();

int count = 1;

int[][] arr = new int[n][n];

for(int i = 0; i<n;i++){

for(int j = 0; j<n;j++){

arr[i][j] = count;

count++; } }

for(int i = 0; i<n;i++){

for(int j = 0; j<n; j++){

System.out.printf(arr[i][j]+" "); }

System.out.println(); } }}

Explanation:

This declares the size of the array

int n;

Scanner input = new Scanner(System.in);

This prompts the user for size of array

System.out.print("Size of array: ");

This gets input for size of array

n = input.nextInt();

This initializes the array element to 1

int count = 1;

This creates a 2d array

int[][] arr = new int[n][n];

This iterates through the rows

for(int i = 0; i<n;i++){

This iterates through the columns

for(int j = 0; j<n;j++){

This populates the array

arr[i][j] = count;

count++; } }

The following nested loop prints the array elements

for(int i = 0; i<n;i++){

for(int j = 0; j<n; j++){

System.out.printf(arr[i][j]+" "); }

System.out.println(); } }}
