Answer:
// code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int length=10,height=7,width=5;
// find the volume of
int vol=length*height*width;
// find the surface area
int sa=2*(length*width+length*height+height*width);
// find the perimeter
int peri=4*(length+width+height);
// print the volume
cout<<"Volume is: "<<vol<<" cm^3."<<endl;
// print the surface area
cout<<"Surface area is: "<<sa<<" cm^2."<<endl;
// print the perimeter
cout<<"Perimeter is: "<<peri<<" cm."<<endl;
return 0;
}
Explanation:
Declare and initialize length=10, width=5 and height=7.calculate volume by multiply length, width and height and assign to variable "vol".Then find the surface area as 2*(length*width+length*height+height*width) and assign it to variable "sa".Then find the perimeter as 4*(length+width+height) and assign to variable "peri". Print the volume, perimeter and surface area.
Output:
Volume is: 350 cm^3.
Surface area is: 310 cm^2.
Perimeter is: 88 cm.
Answer:
The program in Python is as follows:
total = 0
count = 0
for i in range(8):
num = float(input())
if num < 10.5:
total+=num
count+=1
print("Average: ",total/count)
Explanation:
This initializes the total to 0
total = 0
This initializes the count to 0
count = 0
This loop is executed 8 times
for i in range(8):
This request for float number
num = float(input())
If input is less than 10.5
if num < 10.5:
The sum is taken
total+=num
And count is incremented by 1
count+=1
The loop ends here
This calculates and prints the average
print("Average: ",total/count)
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).
