10010100

Explanation:

The given answers are in Binary.

In binary we add the digits in 1 and 0 form.

Addition in Binary:

1 + 0 = 1

0 + 1 = 1

0 + 0 = 0

1 + 1 = 10

Subtraction in Binary:

1 - 0 = 1

1 - 1 = 0

0 - 1 = 1 (it's because the 0 borrows a 1)

0 - 0 = 0

Answer: 01 1 1 0 1 0 1

Explanation:

In Binary addition when you add 1 + 1 = 0, carry over the 1, i.e 10

in Subtraction when you subtract 0-1 = 1, brow 1 from left side, resulting in -1 carried over.

What are issues to consider when deciding to build software in-house or purchase commercial off-the-shelf software (cots)?

Scrat [10]

On the computer there are always issues. For a developer to sit all day in front of a google that always invents things and the flashy images that disrupt everything. Googling on facebook is also an issue. Youtube, everything that contain flashy image is quite disruptive. If you think about content, maybe googling is less inventive. In a way it's nicer to buy applications but if you finally think of building it, there are always nicer ways of spending time. I prefer to go to seaside when I can.

Write a program that asks the user to enter the amount s/he has budgeted for a month. The amount should be between 1000 and 2000

Elena-2011 [213]

Answer:

The program to this question can be given as:

Program:

//import package for user input.

import java.util.*;

//define class

public class Budget

{

public static void main(String [] a) //define main method.

{

//creating Scanner class object.

Scanner ob =new Scanner(System.in);

//define variable.

double budgetamount=0, amountspent=0 ,difference=0,total=0,num=0 ;

int count = 0;

System.out.println("How much have you budgeted for the month? :"); //print message.

budgetamount=ob.nextDouble(); //taking input

while(budgetamount != 0) //checkig number greater then 4 digite.

{

budgetamount= budgetamount/10;

++count;

}

if(count>4) //condition

{

System.out.println("enter each expense, then type -999 to quit: ");

while(num!=-999) //taking expense

{

total=total+num; //totaling expense

num=scan.nextDouble();

}

if(total<=budgetamount) //condtion for over budget.

{

System.out.print("under budget:"); //print message

System.out.print(budgetamount-total);

}

else

{

System.out.print("over budget:"); //for under budget

System.out.print(total-budgetamount);

}

else

{

System.out.println("not valid"); //message for number lessthen 4 digit.

}

output:

How much have you budgeted for the month? : 1200.55.

enter each expense, then type -999 to quit: 365.89

556.90

339.98

-999

over budget:1262.77

Explanation:

The explanation of this program can be given as:

In the above program we import the package in that is used for scanner class. This class is used for the input from the user after input we use the while loop and if-else statement. The while loop is the entry control loop It is used for input validation and if-else is used for the checking condition. Then we insert expense that is inserted by the user. Then we calculate under-budgeted and over-budgeted by conditional statement that is if-else. and at the last we print it.

Two machines can finish a job in StartFraction 20 Over 9 EndFraction hours. Working alone, one machine would take one hour long

Alborosie

Answer

5 hours

Explanation

The two working together can finish a job in

$\frac{20}{9} \: hours$

Also, working alone, one machine would take one hour longer than the other to complete the same job.

Let the slower machine working alone take x hours. Then the faster machine takes x-1 hours to complete the same task working alone.

Their combined rate in terms of x is

$\frac{1}{x} + \frac{1}{x - 1}$

This should be equal to 20/9 hours.

$\frac{1}{x} + \frac{1}{x - 1} = \frac{9}{20}$

Multiply through by;

$20x(x - 1) \times \frac{1}{x} +20x(x - 1) \times \frac{1}{x - 1} = 20x(x - 1) \times \frac{9}{0}$

$20(x - 1) +20x = 9x(x - 1)$

$20x - 20+20x = 9{x}^{2} - 9x$

$9{x}^{2} - 9x - 20x - 20x + 20= 0$

$9{x}^{2} - 49x + 20= 0$

Factor to get:

$(9x - 4)(x - 5) = 0$

$x = \frac{4}{9} \: or \: x = 5$

It is not feasible for the slower machine to complete the work alone in 4/9 hours if the two will finish in 20/9 hours.

Therefore the slower finish in 5 hours.

Hidden costs of computers into our schools

Gala2k [10]

Answer:

There are certainly many hidden costs, and you need to find them out. I am listing some. The GPU can cost a lot if you are using them for complex computing like in the case of Bitcoin. You need to pay heavy electricity bills as well. And if you want to install the webserver then as well, you need to keep your computer open all the time, and pay a good sum as an electricity bill. Many more hidden costs can be found. And one out of above is used in Schools, the webserver. Some more hidden costs can be Network cost, as the school is big, and you need to connect all through LAN, and at times we also need WAN set up. And these are another hidden cost. Various education licenses come for free, and smart classes cost as well. The video conferencing, VOIP, etc costs as well. Smart classes training by various computer training institute for teachers like one from adhesive.
