If parties in a contract are not ____, the contract can be canceled.

Given two integers as user inputs that represent the number of drinks to buy and the number of bottles to restock, create a Vend

ivann1987 [24]

Answer:

In C++:

#include <iostream>

using namespace std;

class VendingMachine {

public:

int initial = 20;};

int main() {

VendingMachine myMachine;

int purchase, restock;

cout<<"Purchase: "; cin>>purchase;

cout<<"Restock: "; cin>>restock;

myMachine.initial-=(purchase-restock);

cout << "Inventory: "<<myMachine.initial<<" bottles";

return 0;}

Explanation:

This question is incomplete, as the original source file is not given; so, I write another from scratch.

This creates the VendingMachine class

class VendingMachine {

This represents the access specifier

public:

This initializes the inventory to 20

int initial = 20;};

The main begins here

int main() {

This creates the object of the VendingMachine class

VendingMachine myMachine;

This declares the purchase and the restock

int purchase, restock;

This gets input for purchase

cout<<"Purchase: "; cin>>purchase;

This gets input for restock

cout<<"Restock: "; cin>>restock;

This calculates the new inventory

myMachine.initial-=(purchase-restock);

This prints the new inventory

cout << "Inventory: "<<myMachine.initial<<" bottles";

return 0;}

lapo4ka [179]

Answer:

The answer to this question is given below in the explanation section. It is noted that this program is written in C++ using online C++ compiler.

Explanation:

#include <iostream>

using namespace std;

int squared(int num)// this is the function to compute square

{

return num*num;

}

int cube(int num)// this is the function to compute cube

{

return num*num*num;

}

int main()

{

int user_num, user_num2; // variable declaration

cout<<"Enter the first number: ";//prompt user to enter the number

cin>>user_num;//store the user entered number into variable

cout<<"\nEnter the second number: ";//prompt the user to enter the second number

cin>>user_num2;//store the user entered number into variable

cout<<"\nSquared of first number is: "<<squared(user_num);//compute square of user_num and display

cout<<"\nCube of first number is: "<<cube(user_num);//compute the cube of the user_num and display

cout<<"\nSquare of second number is: "<<squared(user_num2);//compute the square of user_num2 and display

cout<<"\nCube of second number is: "<<cube(user_num2);//compute the cube of user_num2 and display

cout<<"\nSum of number 1 and number 2 is: "<<user_num2 + user_num2;//display the sum of user_num2 and user_num

cout<<"\nProduct of number 1 and number 2 is: "<<user_num2 * user_num;//display the product of user_num and user_num2

return 0;//terminate the program

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the g

I am Lyosha [343]

Answer:

#program in Python.

#function to calculate driving cost

def driving_cost(d_miles, m_per_gallon, doll_per_gallon):

#calculate cost and return the value

return (d_miles / m_per_gallon) * doll_per_gallon

#read the miles per gallon

m_per_gallon = float(input("Enter car's miles/gallon:"))

#read dollars per gallon

doll_per_gallon = float(input("Enter gas dollars/gallon:"))

#call function to find cost for 10 miles

print('%0.2f' % driving_cost(10, m_per_gallon, doll_per_gallon))

#call function to find cost for 50 miles

print('%0.2f' % driving_cost(50, m_per_gallon, doll_per_gallon))

#call function to find cost for 400 miles

print('%0.2f' % driving_cost(400, m_per_gallon, doll_per_gallon))

Explanation:

Read the value of miles per gallon and assign it to variable "m_per_gallon". Then read dollars per gallon from user and assign it to variable "doll_per_gallon". Call the function driving_cost() with parameter miles, m_per_gallon and doll_per_gallon. This function will find the cost of driving and return the cost.Call function for 10, 50 and 400 miles.

Output:

Enter car's miles/gallon:20

Enter gas dollars/gallon:3.1599

Zoom Vacuum, a family-owned manufacturer of high-end vacuums, has grown exponentially over the last few years. However, the comp

Sati [7]

Answer:

The best advice for Zoom Vacuum is to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users engage with the TPS and generate, retrieve and update the data. it would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products.

Although, TPS alone would not be sufficient enough. so Management Information System(MIS) would be needed, that can get the data from the TPS and process it to get vital information.

This MIS will bring about information regarding the sales and inventory data about the current and well as previous years.

With the combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.

Explanation:

Solution

When we look at the description of the Zoom Vacuum manufacturing company closely, we see that the business is currently a small scale business which is trying to become a small to mid scale business. This claim is supported by the fact that there is only one manufacturing plant and three warehouses. And here, we also need to have the knowledge of the fact that small business major aim is to keep the cost low and satisfy the customers by making good products. So we need to suggest what information system is best suited for small scale business enterprises.

The best recommendation would be to start with a Transaction Processing System(TPS). This system will process all the day to day transactions of the system. It is like a real time system where users interact with the TPS and generate, retrieve and modify the data. This TPS would be very helpful in lowering the cost of production and at the same time manufacture and produce standard quality products . Also TPS can help in communicating with other vendors.

But TPS along would not be sufficient. Also Management Information System(MIS) would be required that can get the data from the TPS and process it to get vital information. This MIS will help in generating information regarding the sales and inventory data about the current and well as previous years. Also MIS can create many types of graphical reports which help in tactical planning of the enterprise.

So a combination of TPS as well as MIS is a minimum requirement for a Zoom Vacuum to become successful in the market.

Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that pac

Katarina [22]

Answer:

The Tp value 0.03 micro seconds as calculated in the explanation below is negligible. This would lead to a similar value of time delay for both persistent HTTP and non-persistent HTTP.

Thus, persistent HTTP is not faster than non-persistent HTTP with parallel downloads.

Explanation:

Given details are below:

Length of the link = 10 meters

Bandwidth = 150 bits/sec

Size of a data packet = 100,000 bits

Size of a control packet = 200 bits

Size of the downloaded object = 100Kbits

No. of referenced objects = 10

Ler Tp to be the propagation delay between the client and the server, dp be the propagation delay and dt be the transmission delay.

The formula below is used to calculate the total time delay for sending and receiving packets :

d = dp (propagation delay) + dt (transmission delay)

For Parallel downloads through parallel instances of non-persistent HTTP :

Bandwidth = 150 bits/sec

No. of referenced objects = 10

For each parallel download, the bandwith = 150/10

= 15 bits/sec

10 independent connections are established, during parallel downloads, and the objects are downloaded simultaneously on these networks. First, a request for the object was sent by a client . Then, the request was processed by the server and once the connection is set, the server sends the object in response.

Therefore, for parallel downloads, the total time required is calculated as:

(200/150 + Tp + 200/150 + Tp + 200/150 + Tp + 100,000/150 + Tp) + (200/15 + Tp + 200/15 + Tp + 200/150 + Tp + 100,000/15 + Tp)

= ((200+200+200+100,00)/150 + 4Tp) + ((200+200+200+100,00)/15 + 4Tp)

= ((100,600)/150 + 4Tp) + ((100,600)/15 + 4Tp)

= (670 + 4Tp) + (6706 + 4Tp)

= 7377 + 8 Tp seconds

Thus, parallel instances of non-persistent HTTP makes sense in this case.

Let the speed of propogation of the medium be 300*106 m/sec.

Then, Tp = 10/(300*106)

= 0.03 micro seconds

The Tp value 0.03 micro seconds as calculated above is negligible. This would lead to a similar value of time delay for both persistent HTTP and non-persistent HTTP. Thus, persistent HTTP is not faster than non-persistent HTTP with parallel downloads.
