1. manage the computer's resources (this includes the central processing unit, memory, printers, and disk drives).

2. establish a user interface (this is where the human interacts with a computer, website or application. the UI, also known as user interface, is to make the user's experience easy and intuitive).

3. execute and provide services for applications software (this is the interface between the application program and the hardware, which gets carried out from OS).

An employee’s total weekly pay equals the hourly wage multiplied by the total number of regular hours plus any overtime pay. Ove
Feliz [49]

Answer:

C++ programming language is used to implement this program using Dev C++. You can use any C++ compiler to run this program. The code and its explanation is given below in explanation section.

Explanation:

#include<iostream>

using namespace std;

int main()

{

int totalWeeklyPay;//total weekly pay  

int hourlyWage;// wages per hours

 

int totalRegularHour;// total regular hours worked

int totalOverTimeHour;// total over time hours worked

 

int weeklyTotalRegularPay;

int weeklyTotalOverTimePay;

 

cout<<"Enter Wage per hour: ";

 cin>>hourlyWage;

 if (hourlyWage<0)//if use enter negative value

  {

   cout<<"Please enter positive number number for wage per hour\n";

   cout<<"Enter Wage per hour: ";

     cin>>hourlyWage;

  }

cout<<"Enter total regular hour: ";

cin>>totalRegularHour;

if (totalRegularHour<0)//if user enter negative value

  {

   cout<<"Please enter positive total number of regular hour\n";

  cout<<"Enter total regular hour: ";

     cin>>totalRegularHour;

  }

cout<<"Enter total over time hour: ";

cin>>totalOverTimeHour;

 

 if(totalOverTimeHour<0)//if user enter negative value

   {

    cout<<"Please enter positive total number of over time hour\n";

  cout<<"Enter total over time hour: ";

  cin>>totalOverTimeHour;

     

     

 }

 

weeklyTotalRegularPay =hourlyWage*totalRegularHour;// total weekly regular hour pay

weeklyTotalOverTimePay=totalOverTimeHour*hourlyWage*1.5;// total weekly overtime pay

totalWeeklyPay=weeklyTotalRegularPay + weeklyTotalOverTimePay;//total weekly regular hour pay + // total weekly overtime pay

cout<<"Total Weekly Pay is: "<<totalWeeklyPay<<"$";//output

 

 

return 0;

In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hou
mestny [16]

Answer:

Bike Frame Flow Time

The value-added percentage of the flow time for this bike frame is:

= 46.

Explanation:

a) Data and Calculations:

Bike Frame Flow Time:

Setup time = 7 hours

Processing time = 6 hours

Storage time = 7 hours

Flow time of the bike frame = 13 hours (7 + 6)

Value-added percentage of the flow time for this bike frame = 6/13 * 100

= 46%

b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end.  It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path.  The storage time is not included in the flow time since it is not a manufacturing process.

Implement a function inValues() that asks the user to input a set of nonzero floating-point values. When the user enters a value
elena-s [515]

Answer:

Explanation:

The following is written in Python and uses exception handling to do exactly as requested. It then goes adding all of the integer values to an array called num_list and finally adding them all together when the function ends.

def in_values():

   num_list = []

   while True:

       try:

           num = input("Input non-zero floating point: ")

           num = int(num)

           if num == 0:

               break

           else:

               num_list.append(num)

       except ValueError:

           print("No valid integer! Please try again ...")

           try:

               num = input("Input non-zero floating point: ")

               num = int(num)

               break

           except ValueError:

               break

   sum = 0

   for number in num_list:

       sum += number

   return sum
