Answer:

Answered in C++

double ConvertToInches(double numFeet, double numInches){

return numFeet*12 + numInches;

}

Explanation:

A foot is equivalent to 12 inches. So, the function converts feet to inches by multiplying the number of feet by 12.

The question is answered in C++

This line defines the method with two parameters

double ConvertToInches(double numFeet, double numInches){

This line converts the input parameters to inches and returns the number of inches

return numFeet*12 + numInches;

}

To convert 9 feet and 12 inches to inches, the main method of the program can be:

int main(){

cout<<ConvertToInches(9,12);

return 0;

}

This above will return 120 because: 9 * 12 + 12 = 120 inches

A proper divisor of a positive integer $n$ is a positive integer $d < n$ such that $d$ divides $n$ evenly, or alternatively i

juin [17]

Answer:

The program written in Python is as follows:

See Explanation section for line by line explanation

for n in range(100,1000):

isum = 0

for d in range(1,n):

if n%d == 0:

isum += d

if isum == n * 2:

print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

isum = 0

This line is an iteration that stands as the divisor

for d in range(1,n):

This line checks if a number, d can evenly divide n

if n%d == 0:

If yes, the sum is updated

isum += d

This line checks if the current number n is a double-perfect number

if isum == n * 2:

If yes, n is printed

print(n)

When the program is run, the displayed output is 120 and 672

Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha. Wri

Alina [70]

Answer:

In Java:

public static int[] inputArray(){

Scanner input = new Scanner(System.in);

int[] alpha = new int[20];

for(int i = 0;i<20;i++){

alpha[i] = input.nextInt();

}

return alpha;}

public static int[] doubleArray(int [] alpha){

int[] beta = new int[20];

for(int i = 0;i<20;i++){

beta[i] = 2 * alpha[i];

}

return beta;

}

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

int [] AlphaBeta = new int[10];

for(int i = 0;i<5;i++){

AlphaBeta[i] = alpha[i];

}

int count = 5;

for(int i = 15;i<20;i++){

AlphaBeta[count] = beta[i];

count++;

}

return AlphaBeta;

}

public static void printArray(int [] alpha){

for(int i = 0;i<20;i++){

System.out.print(alpha[i]+" ");

if((i+1)%15 == 0){

System.out.println(" ");

}

Explanation:

The inputArray is defined here

public static int[] inputArray(){

Scanner input = new Scanner(System.in);

This declares alpha array of 20 elements

int[] alpha = new int[20];

The following iteration gets input from the user into the array

for(int i = 0;i<20;i++){

alpha[i] = input.nextInt();

}

This returns the alpha array

return alpha;}

The doubleArray is defined here. It takes the alpha array as its input parameter

public static int[] doubleArray(int [] alpha){

This declares beta of 20 integers

int[] beta = new int[20];

This populates beta by 2 * alpha[i]

for(int i = 0;i<20;i++){

beta[i] = 2 * alpha[i];

}

This returns the alpha array

return beta;}

The copyAlphaBeta array is defines here

public static int[] copyAlphaBeta(int [] alpha, int [] beta){

This declares AlphaBeta as 10 elements

int [] AlphaBeta = new int[10];

This populates the first 5 elements of AlphaBeta with the first 5 of alpha

for(int i = 0;i<5;i++){

AlphaBeta[i] = alpha[i];

}

int count = 5;

This populates the last 5 elements of AlphaBeta with the last 5 of beta

for(int i = 15;i<20;i++){

AlphaBeta[count] = beta[i];

count++;

}

This returns the AlphaBeta array

return AlphaBeta;

}

The printArray is defined here. It takes the alpha array as its input parameter

public static void printArray(int [] alpha){

This iterates through alpha array

for(int i = 0;i<20;i++){

This prints each element of the array

System.out.print(alpha[i]+" ");

A new line is started after the 15th element

if((i+1)%15 == 0){

System.out.println(" ");

}

}

Create a Python program that:

Charra [1.4K]

Answer:

```

file = open("trips.txt","r")

file = file.split("\n")

trip_date = []

fuel_used = []

miles_traveled = []

for i in file:

trip_date.append(i.split(", ")[0])

for i in file:

fuel_used.append(i.split(", ")[1])

for i in file:

miles_traveled.append(i.split(", ")[2])

```

This should put the data in their own lists (i didn't test it) but im not going to solve everything for you. The rest is for you to tinker with. You shouldn't throw your question at us and expect an answer. This is the most that I will give you.
