Use JavaWrite a program that will simulate a change machine found at cash registers. Input the amount due and amount paid from the keyboard.Tell the user how much change is owed and number of quarters, dimes, nickels, and pennies in change a customer would receive.Pay special attention to roundoff error. Your program should use division and modular division. No if’s or loops may be used. You may assume all change will be a positive number with no more than two decimal places. If more than $1.00 is owed, the full value should be included in the number of quarters returned. For example, $2.50 should be returned as 10 quarters.Hint: Modular division is a great way to find the remainder of a division. Think about how you can use this to calculate the change that is left over after some coins are given.Sample Run:Please Enter the Cost of the Item:4.57Please Enter the Amount Paid:5.00Change Owed: 0.43Quarters: 1Dimes: 1Nickels: 1Pennies: 3

Answers

Answer 1

Answer:

Here is the JAVA program:

import java.util.Scanner; //to accept input from user

public class Main { // class name

public static void main(String [] args) { // start of main method

Scanner input = new Scanner(System.in); // creates Scanner class object to take input from user

System.out.println("Please Enter the Cost of the Item: "); // prompts user to enter the cost of item

double itemCost = input.nextDouble(); //scans and reads the input value of item cost

System.out.println("Please Enter the Amount Paid: "); // prompts user to enter the amount paid

double amount = input.nextDouble(); //scans and reads the value of amount from user

int change = (int)(amount * 100 - itemCost * 100); //compute the remaining amount i.e. change

System.out.println("Change Owed: " + change / 100.0); // displays the owed change

int quarters = change / 25; // computes the value for quarters

change = change % 25; // compute the quarters remaining

int dimes = change / 10; // computes dimes

change = change % 10; // computes dimes remaining

int nickels = change / 5; // computes nickels

change = change % 5; // compute nickels remaining

int pennies = change; // computes pennies

System.out.println("Quarters: " + quarters); // displays computed value of quarters

System.out.println("Dimes: " + dimes); // displays value of dimes

System.out.println("Nickels: " + nickels); // displays value of nickels

System.out.println("Pennies: " + pennies); }} //displays value of pennies

Explanation:

I will explain the program with an examples.

Suppose the user enters 4.57 as cost of the item and 5.00 as amount paid. Then the program works as follows:

Change is computed as

change = (int)(amount * 100 - itemCost * 100);

This becomes;

change = (int)(5.00 * 100 - 4.57 * 100)

= 500 - 457

change = 43

Now the change owed is computed as:

change / 100.0 = 43/100.0 = 0.43

Hence change owed = 0.43

Next quarters are computed as:

quarters = change / 25;

This becomes:

quarters = 43/25

quarters = 1

Now the remaining is computed as:

change = change % 25;

This becomes:

change = 43 % 25;

change = 18

Next the dimes are computed from remaining value of change as:

dimes = change / 10;

dimes = 18 / 10

dimes = 1

Now the remaining is computed as:

change = change % 10;

This becomes:

change = 18 % 10

change = 8

Next the nickels are computed from remaining value of change as:

nickels = change / 5;

nickels = 8 / 5

nickels = 1

Now the remaining is computed as:

change = change % 5;

This becomes:

change = 8 % 5

change = 3

At last the pennies are computed as:

pennies = change;

pennies = 3

So the output of the entire program is:

Change Owed: 0.43 Quarters: 1 Dimes: 1 Nickels: 1 Pennies: 3

The screenshot of the output is attached.

And office now has a total of 35 employees 11 were added last year the year prior there was a 500% increase in staff how many staff members were in the office before the increase

Answers

There were 5 staff members in the office before the increase.

To find the number of staff members in the office before the increase, we can work backward from the given information.

Let's start with the current total of 35 employees. It is stated that 11 employees were added last year.

Therefore, if we subtract 11 from the current total, we can determine the number of employees before the addition: 35 - 11 = 24.

Moving on to the information about the year prior, it states that there was a 500% increase in staff.

To calculate this, we need to find the original number of employees and then determine what 500% of that number is.

Let's assume the original number of employees before the increase was x.

If we had a 500% increase, it means the number of employees multiplied by 5. So, we can write the equation:

5 * x = 24

Dividing both sides of the equation by 5, we find:

x = 24 / 5 = 4.8

However, the number of employees cannot be a fraction or a decimal, so we round it to the nearest whole number.

Thus, before the increase, there were 5 employees in the office.

If a device has obtained an IP address using Link Local, which IP configuration would be within its subnet?

Answers

Answer:

If a device has obtained an IP address using Link Local, its IP configuration will be within the 169.254.0.0/16 subnet.

Explanation:

The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254 if a device received an IP address. 0.0/16

A link-local address is a unicast network address that is valid only for communications within the subnetwork to which the host is linked. Link-local addresses are typically issued automatically by a method known as stateless address autoconfiguration or link-local address autoconfiguration,[1] sometimes known as automatic private IP addressing (APIPA) or auto-IP. As a result, routers do not forward packets that have link-local source or destination addresses. IPv4 link-local addresses are assigned from the address block 169.254.0.0/16.

The Address Resolution Protocol (ARP) is used to convert between Layer 2 MAC addresses and Layer 3 IP addresses.ARP resolves IP addresses to MAC addresses by requesting, "Who owns the IP address 192.168.2.140, please inform me?" They are assigned from the block that may be configured inside its subnet.ARP resolves IP addresses to MAC addresses by requesting, "Who owns the IP address 192.168.2.140, please inform me?"

A motor takes a current of 27.5 amperes per leaf on a 440-volt, three-phase circuit. The power factor is 0.80. What is the load in watts? Round the answer to the nearer whole watt.

Answers

The load in watts for the motor is 16766 watts

To calculate the load in watts for the given motor, you can use the following formula:

Load (W) = Voltage (V) × Current (I) × Power Factor (PF) × √3

In this case:
Voltage (V) = 440 volts
Current (I) = 27.5 amperes per phase
Power Factor (PF) = 0.80
√3 represents the square root of 3, which is approximately 1.732

Now, plug in the values:

Load (W) = Voltage (V) × Current (I) × Power Factor (PF) × √3

Load (W) = 440 × 27.5 × 0.80 × 1.732

Load (W) = 16765.7 watts

Rounded to the nearest whole watt, the load is approximately 16766 watts.

Why is hydroelectricity counted as a conventional source of energy.. People say conventional sources of energy is the same as non-renewable energy sources

Answers

People have been using the energy of flowing or falling water for centuries before electricity was developed into a practical means of transporting energy. The first hydroelectric plant (at least in the U.S.) was built at Niagara Falls in 1895. Many areas of the world still get the majority of their power from hydro facilities.

Hydro is also “conventional” in the sense that it can be controlled in more or less the same way as thermal plants — its output can be adjusted over a wide range to match demand. Wind and solar, on the other hand, only produce when the wind blows or the sun shines. Of course, hydro can only produce as long as there’s rain or snowmelt to supply the reservoirs, but that’s on a much longer time scale; over hours or days, hydro capacity is very predictable.

Burnout can happen quickly when working with multiple sysadmins, working overtime, or working as the sole sysadmin.

Explanation:

Given three subroutines of 550, 290, and 600 words each, if segmentation is used then the total memory needed is the sum of the three sizes (if all three routines are loaded). However, if paging is used, then some storage space is lost because subroutines rarely fill the last page completely, and that results in internal fragmentation. Determine the total amount of wasted memory due to internal fragmentation when the three subroutines are loaded into memory using each of the following page sizes:
a. 100 words
b. 600 words
c. 700 words
d. 900 words

Answers

The answer is D i got it right when I did it

Typically, external fragmentation wastes one-third of memory. Internal fragmentation occurs when space inside a designated region is wasted. Thus, option D is correct.

What wasted memory due to internal fragmentation?

The mounted-sized block is allotted to a method whenever a request for memory is made. Internal fragmentation is the term used to describe the situation where the memory allotted to the method is a little bigger than the amount requested.

Normally, memory is allocated in uniformly sized blocks, but sometimes a process doesn't use the entire block, leading to internal fragmentation.

Memory fragmentation occurs when a memory allocation request can be satisfied by the whole amount of accessible space in a memory heap, but no single fragment (or group of contiguous fragments) can.

Therefore, when the three subroutines are loaded into memory using each of the following page sizes 900 words.

Broken down by: a) year b) balance at end of year

Finance formula of A= P(1+ r/n)^n*t is used:

A = Future Value | P = Initial Investment

r = annual interest rate |n = times interest is compounded/year

t = years invested
