Answer:

The largest dimensions we can make of an image with the pixelation widget is 255*255.

When an image is resized, the number of pixels in the image may be reduced or increased, which causes the image to be resampled. Resampling changes the file size.

Explanation: This is all I could find. I hope its helps Sorry.

Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combinin
Dmitry_Shevchenko [17]

Answer:

Follows are the code to this question:

#include<iostream>//defining header file

using namespace std;// use package

int main()//main method

{

int red,green,blue,x;//declaring integer variable

cin>> red >>green>>blue;//use input method to input value

if(red<green && red<blue)//defining if block that check red value is greater then green and blue  

{

x = red;//use x variable to store red value

}

else if(green<blue)//defining else if block that check green value greater then blue  

{

x= green; //use x variable to store green value

}

else//defining else block

{

x=blue;//use x variable to store blue value

}

red -= x;//subtract input integer value from x  

green -=x; //subtract input integer value from x

blue -= x;//subtract input integer value from x

cout<<red<<" "<<green<<" "<<blue;//print value

return 0;

}

Output:

130 50 130

80 0 80

Explanation:

In the given code, inside the main method, four integers "red, green, blue, and x" are defined, in which "red, green, and blue" is used for input the value from the user end. In the next step, a conditional statement is used, in the if block, it checks red variable value is greater than then "green and blue" variable. If the condition is true, it will store red variable value in "x", otherwise, it will goto else if block.

  • In this block, it checks the green variable value greater than the blue variable value. if the condition is true it will store the green variable value in x variable.
  • In the next step, else block is defined, that store blue variable value in x variable, at the last step input variable, is used that subtracts the value from x and print its value.

Give a recursive (or non-recursive) algorithm to compute the product of two positive integers, m and n, using only addition and
LiRa [457]

Answer:

Multiply(m,n)

1. Initialize product=0.

2. for i=1 to n

3.      product = product +m.

4. Output product.

Explanation:

Here we take the variable "product" to store the result m×n. And in this algorithm we find m×n by adding m, n times.

Which formula would you enter into C3, and then AutoFill into C4 through C6, to calculate the percent sales (Pct.) for the regio
inna [77]

Answer:

In C3, you would enter the formula:

  • =B3/$B$7%

Explanation:

Let's assume the first row is 1 and it contains the titles of the columns.  For instance, the content of the cellss A1:C1 could be:

  • A1: Region
  • B1: Sales
  • C1: Percent Sales

Also, assume the second row is empty and the cells on the first column, A, contain the names of four regions. For instance, North, South, East, and West:

  • A3: North
  • A4: South
  • A5: East
  • A6: West

The cells B3:B6 contain the sales for the four regions. For instance:

  • B3: 200
  • B4: 300
  • B5: 100
  • B6: 400

Then, you must calculate the percent sales for every region, in the cells <em>C3:C6.</em>

That means, you must divide the sale of every region by the total of sales and multiply by 100.

To do that in the worksheet you do this:

<u>1. Sum the sales for the regions:</u>

  • In cell B7 introduce: =SUM(B3:B6)

<u>2. Calculate the percent sale for the first region:</u>

  • In cell C3 introduce: =B3/$B$7%

That means that the reference B3 is relative: when you copy that formula, the column (B) and the row (3) will change accordingly to the cell where you will copy it.

Thus, by using the Autofill into C4 through C6, the column wil remain unchanged (C) and the row will change to 4, 5, and 6, respectively.

The symbol $ used in $B$7 make the reference absolute. That means that they will not change. The symbol % makes that the result is multiplied by 100.

<u>3. When you use Autofull into C4 through C6, you obtain:</u>

  • C4: =B4/$B$7%
  • C5: =B5/$B$7%
  • C6: =B6/$B$7%
