Answer:
packet filtering
Explanation:
We can use a packet filtering firewall, for something like this, reasons because when visiting a site these types of firewalls should block all incoming traffic and analyze each packet, before sending it to the user. So if the packet is coming from a malicious origin, we can then drop that packet and be on our day ;D
Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- System.out.print("Input total sales of month: ");
- double totalSales = input.nextDouble();
-
- double stateTax = totalSales * 0.04;
- double countyTax = totalSales * 0.02;
- double totalSalesTax = stateTax + countyTax;
-
- System.out.println("County Tax: $" + countyTax);
- System.out.println("State Tax: $" + stateTax);
- System.out.println("Total Sales Tax: $" + totalSalesTax);
- }
- }
Explanation:
Firstly, create a Scanner object and prompt user to input total sales of month (Line 5-7). Next, apply the appropriate tax rate to calculate the state tax, county tax (Line 9 - 10). Total up the state tax and county tax to get the total sales tax (Line 11).
At last, print the county tax, state tax and the total sales tax (Line 13 - 15).
Here you go,
flowrate.m
cbps = input('Enter the flow in m^3/sec: ');
cfps = cbps ./ 0.028;
fprintf('A flow rate of %.3f meters per sec\n', cbps);
fprintf('is equivalent to %.3f feet per sec\n', cfps);
