Answer: To be useful for most household applications, DC voltage is passed through a step-down transformer.
Explanation: Voltage coming through AC or DC outlets is typically far too high for most household appliances to handle, so the current is passed through a step-down transformer to reduce the voltage to a usable level.
Answer:
TAX_RATE = 0.20
STANDART_DEDUCTION = 10000.0
DEPENDENT_DEDUCTION = 3000.0
gross_income = float(input("Enter the gross income: "))
number_of_dependents = int(input("Enter the number of dependents: "))
income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents)
tax = income * TAX_RATE
print ("The income tax is $" + str(round(tax, 2)))
Explanation:
Define the <em>constants</em>
Ask user to enter the <em>gross income</em> and <em>number of dependents</em>
Calculate the <em>income</em> using formula (income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents))
Calculate the <em>tax</em>
Print the <em>tax</em>
<em />
round(number, number of digits) -> This is the general usage of the <em>round</em> function in Python.
Since we need <u>two digits of precision</u>, we need to modify the program as str(<u>round(incomeTax, 2</u>)).
Answer:
Algorithm:
1. Declare an integer variable N.
2. Read the value N from user.
3.While(N):
3.1 find r=N%10;
3.2 print r in new line.
3.3 Update N as N=N/10.
4.end program.
Implementation in C++.
// header
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variable
int N;
cout<<"Enter an Integer:";
cin>>N;
// find the digits of number
while(N)
{
// last digit
int r=N%10;
// print last digit
cout<<r<<endl;
// update the number
N=N/10;
}
return 0;
}
Output:
Enter an Integer:329

It is okay but you should be able to type up to 60+ words per minute and keep doing that to practice then if you can get into a typing class.
