Write a program that calculates the area & perimeter of a rectangle, where
the values for width and length are given by the users.
Answer:
In Python:
Length = float(input("Length: "))
Width = float(input("Width: "))
Area = Length * Width
Perimeter = 2*(Length + Width)
print(Area)
print(Perimeter)
Explanation:
This gets the length from the user
Length = float(input("Length: "))
This gets the width from the user
Width = float(input("Width: "))
This calculates the area
Area = Length * Width
This calculates the perimeter
Perimeter = 2*(Length + Width)
This prints the area
print(Area)
This prints the perimeter
print(Perimeter)

What is the influence of new technology on society?
Ο Α. .
New technology hardly has any impact on society.
OB.
New technology is only beneficial to society and cannot be detrimental.
OC.
New technology is detrimental, as it makes the existing technology obsolete.
OD. New technology normally utilizes a lot of resources and can adversely affect the economy.
O E.
New technology is beneficial but can also be usedly a detrimental way.
Answer:
E. New technology is beneficial but can also be used in a detrimental way.
Explanation:
New technology such as cryptocurrency (powered by blockchain technology) can be regarded as a welcome development that has benefited the society in so many good ways. However, cryptocurrency as a new technology also has disadvantages it presents to the society. One of such negative influence cryptocurrency has is that it can be used for illicit activities such as money laundering, funding terrorism and so on.
So, in summary, we can conclude that:
"New technology is beneficial but can also be used in a detrimental way."

It just is
Answer:
B is correct
Explanation:
Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:
As long as x is greater than 0
Output x % 2 (remainder is either 0 or 1)
x = x // 2
Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string.
Ex: If the input is:
6
the output is:
110
Your program must define and call the following two functions. The function integer_to_reverse_binary() should return a string of 1's and 0's representing the integer in binary (in reverse). The function reverse_string() should return a string representing the input string in reverse.
def integer_to_reverse_binary(integer_value)
def reverse_string(input_string)
Note: This is a lab from a previous chapter that now requires the use of a function.
Answer:
#include <iostream>//header file
#include <string>//header file
using namespace std;
string integer_to_reverse_binary(int integer_value)//defining a method integer_to_reverse_binary
{
string ret = "";//defining string variable
while (integer_value > 0) //using while loop to check integer_value value is greater than 0
{
ret += '0' + (integer_value % 2);//adding zeros in remainder value
integer_value /= 2;//holding quotient value
}
return ret;//return string value
}
string reverse_string(string input_string)//defining a method reverse_string that holds a parameter user_String
{
string result;//defining a string variable
for (int i = 0; i < input_string.length(); ++i)//use for loop to calculate value
{
result += input_string[input_string.length()-i-1];//add value in result variable
}
return result;//result result variable value
}
int main()//defining main method
{
int num;//defining integer variable
string str;//defining string variable
cin >> num;//input num value
str = integer_to_reverse_binary(num);//use str variable to call the integer_to_reverse_binary method
cout << reverse_string(str) << endl;//printing the reverse_string method value
return 0;
}
Output:
6
110
Explanation:
In this code two string method "integer_to_reverse_binary and reverse_string" is defined that holds one parameter "integer_value and input_string".
In the first method a string variable is defined, that use the while loop to check integer value is greater than 0 and add zeros in the value and return its value as a string.
In the second it reverse the string value and store into the result variable, and in the main method the "num and str" variable is defined, and in the num it takes integer value and pass into the above method and print its return value.
CH4 has how many of each type of atom?
Its easy that moderators that see this answer can think that my answer isn't without explanation.
• Type of atom C (Carbon)
C = 1
• Type of atom H (Hydrogen)
H = 4
You dont understand? JUST SEE THE FORMULA C MEANS ONLY HAVE 1 CARBON ATOM AND H4 MEANS 4 ATOM OF HYDROGEN
oK. have a nice day hope you understands
