Explanation:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Variables to store inputs

string robot_name = "Nao";

string visitor_name;

int age, first_num, second_num;

// Constant variable initialisation for programmer name

const string programmer_name = "XXXXXXXX";

// Constant variable initialisation for assignment number

const string assignment_num = "123546";

// Constant variable initialisation for due date

const string due_date = "16 August, 2019";

// Displaying robot's name as script

cout << "Hello, welcome to Montgornery College!";

cout << "My name is " << robot_name << " . May I have your name?" << "\n\n";

// Taking visitor's name as input from the visitor

cout << "Let me impress you with a small game.";

cout << "Give me the age of an important person or a pet to you. ";

cout << "Please give me only a number!" << "\n\n";

// Taking human age as input from the visitor

// Taking first whole number from the visitor

cin >> first_num;

cout << "\nVery well. Give me another whole number." << "\n\n";

what is the molarity of a solution prepared by dissolving 15.0g of sodium hydroxide in enough water to make a total of 225 ml of
Reptile [31]

Answer:

1.6666 g/mol = 1 \frac{2}{3} g/mol

Explanation:

Molar mass of NaOH= 23+16+1 =40g/mol

Mols in 15g = 15/40 mol

If this was dissolved in 225ml of water molarity of the solution is

\frac{15}{40} ÷ 225 x 1000 = 1.6666 g/mol = 1 \frac{2}{3} g/mol

Assume that cell F5 to F10 In a spreadsheet contains numeric value of salary earned by some workers and cell F12 contains the va
snow_tiger [21]

Answer:

=F5*$F$12+F5

Explanation:

If we want to increment the salaries in the cell F5, we must multiply the cell F5 by cell F12, and then we must sum that result.

If we want to drag the formula from the cell F5 to F10, we must use the dollar symbol $ to apply the same percent in our formula.

For example:

F12 = 5% = 0.05

F5 = 10,000

=F5*$F$12+F5

=10,000×0.05+10,000 = 10,500
