Answer:

Let's convert the decimals into signed 8-bit binary numbers.

As we need to find the 8-bit magnitude, so write the powers at each bit.

      <u>Sign -bit</u> <u>64</u> <u>32</u> <u>16</u> <u>8</u> <u>4</u> <u>2</u> <u>1</u>

+25 - 0 0 0 1 1 0 0 1

+120- 0 1 1 1 1 0 0 0

+82 - 0 1 0 1 0 0 1       0

-42 - 1 0 1 0 1 0 1 0

-111 - 1 1 1 0 1 1 1 1

One’s Complements:  

+25 (00011001) – 11100110

+120(01111000) - 10000111

+82(01010010) - 10101101

-42(10101010) - 01010101

-111(11101111)- 00010000

Two’s Complements:  

+25 (00011001) – 11100110+1 = 11100111

+120(01111000) – 10000111+1 = 10001000

+82(01010010) – 10101101+1= 10101110

-42(10101010) – 01010101+1= 01010110

-111(11101111)- 00010000+1= 00010001

Explanation:

To find the 8-bit signed magnitude follow this process:

For +120

  • put 0 at Sign-bit as there is plus sign before 120.
  • Put 1 at the largest power of 2 near to 120 and less than 120, so put 1 at 64.
  • Subtract 64 from 120, i.e. 120-64 = 56.
  • Then put 1 at 32, as it is the nearest power of 2 of 56. Then 56-32=24.
  • Then put 1 at 16 and 24-16 = 8.
  • Now put 1 at 8. 8-8 = 0, so put 0 at all rest places.

To find one’s complement of a number 00011001, find 11111111 – 00011001 or put 0 in place each 1 and 1 in place of each 0., i.e., 11100110.

Now to find Two’s complement of a number, just do binary addition of the number with 1.

Several students are making presentations for a science class. The chart describes the concept that each student will present to
Sedbober [7]

Question

Student presentation concepts from another source

Letitia - a step-by-step process of breaking down glucose into energy

Mana - repeating process of the steps of the cell division, going from interphase to division, and back to interphase.

Paul - a series of organisms that show similar characteristics and compare them to those that do not

Which best describes the SmartArt graphic layout each student should use?

Answer:

Letitia would use a process, Maria would use a cycle, and Paul would use a relationship.

Explanation:

Letita's assignment requires her to show how glucose can be broken down into energy, this requires a series of steps in s linear fashion, meaning it would be best suited to a process-style diagram.

Marta's project involves showing the steps of the cell cycle: the clue is in the name. This process is not linear, and instead repeats itself, meaning it fits to a cycle diagram (i.e. a circular diagram)

Paul is comparing and contrasting different organisms. Therefore, he should use a relationship diagram to show shared characteristics as well as features that differ.

vekshin1

Answer:

public class Calculator {

   private int total;

   private int value;

   

   public Calculator(int startingValue){

       // no need to create a new total variable here, we need to set to the our instance total variable

       total = startingValue;

       value = 0;

   }

   public int add(int value){

       //same here, no need to create a new total variable. We need to add the value to the instance total variable

       total = total + value;

       return total;

   }

   /**

   * Adds the instance variable value to the total

   */

   public int add(){

       // no need to create a new total variable. We need to add the value to the instance total variable

       total += value;

       return total;

   }

   public int multiple(int value){

       // no need to create a new total variable. We need to multiply the instance total variable by value.

       total *= value;

       return total;

   }

   //We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.

   public void setValue(int value){

       this.value = value;

   }

   public int getValue(){

       return value;

   }

}
