Convert 234.43 (base 7) to base 10

miss Akunina [59]

Answer:

123.6326

Explanation:

Given number in base 7 : 234.43

Converting to base 10:

Each digit needs to be multiplied by 7^(position index)

Applying this for all the digits in the number:

=2* 7^2 + 3*7^1 + 4*7^0 + 4*7^-1 + 3*7^-2

=2*49 + 3*7 + 4 + 4/7+3/49

=98 + 21 + 4 + 0.5714 + 0.0612

Separating the integer and fraction parts:

=(98 + 21 + 4) + (0.5714 + 0.0612)

=123.6326

So the base 10 equivalent value for 234.43(base 7) is 123.6326

Instructions

Thepotemich [5.8K]

The output file stream will be coded as such

ofstream output_file;

output_file.open("Ch4_Ex15_Output.txt", ios::out);

output_file << balance;

input.close();

output_file.close();

return 0;

}

<h3>Output file stream</h3>

Generally, Given the instructions we see that the program will "output account balance before and after withdrawal and service charges"

Therefore we must conclude at the output file stream bearing all information required.

double withdraw(double balance) {

cout << "Current Balance in the account: " << balance << endl;

if(balance <= 0) {

cout << "Insufficent balance" << endl;

return balance;

}

double withdraw;

cout << "Amount of money for withdraw: "; cin >> withdraw;

if(withdraw > 500) {

cout << "$500 per day can be withdrawn!";

return balance;

}

double charge = 0;

if(balance >= withdraw) {

balance -= withdraw;

charge = (withdraw <= 300) ? 0 : (withdraw - 300) * 0.04;

}

else {

char option;

cout << "Insufficient funds! Service charged $25, Want to withdraw money?(Y/N): ";

cin >> option;

if(option == 'Y' || option == 'y') {

balance -= withdraw;

charge = 25;

}

balance -= charge;

cout << "balance after Withdraw: " << balance << endl;

cout << "charge for transaction: " << charge << endl;

return balance;

}

int main() {

ifstream input;

input.open("Ch4_Ex15_Data.txt", ios::in);

double balance;

input >> balance;

balance = withdraw(balance);

ofstream output_file;

\therefore the output stream is

output_file.open("Ch4_Ex15_Output.txt", ios::out);

output_file << balance;

input.close();

output_file.close();

return 0;

}

The area of a square is stored in a double variable named area. write an expression whose value is length of the diagonal of the

ale4655 [162]

You should specify what language you're using in these types of questions; here's an example in C++.

#include <iostream>
#include <math>

int main()
{
// example area
double area = 25;

// square root the area to find the length
// then apply basic pythagoras
double diagonal = sqrt(pow(sqrt(area), 2) + pow(sqrt(area), 2));

return 0;
}

Consider the method get Hours, which is intended to calculate the number of hours that a vehicle takes to travel between two mil

mr Goodwill [35]

Answer:

Replace the comment with:

(c) double hours = Math.abs (marker1 - marker2) / 60.0;

Explanation:

See attachment for right presentation of question

Analyzing the options:

(a): May return a negative result

This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.

This literally is not different from marker1 - marker2

(b): Incorrect expression

This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.

(c) This option is correct

This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)

(d) & (e) Integer division

When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
