lawyer [7]

Answer:

An employer with workers exposed to high temperatures should establish a complete heat illness prevention program. Provide workers with water, rest and shade. Allow new or returning workers to gradually increase workloads and take more frequent breaks as they acclimatize, or build a tolerance for working in the heat.

Convert each of the following 8-bit numbers to hexadecimal and then to octal a) 10011101 b) 00010101 c) 11100110 d) 01101001

EastWind [94]

<h2>Answer:</h2>

a) 10011101₂ = 9D₁₆ or 235₈

b) 00010101₂ = 15₁₆ or 025₈

c) 11100110₂ = E6₁₆ or 346₈

d) 01101001₂ = 69₁₆ or 151₈

<h2>Explanation:</h2>

An hexadecimal is a group of 4bits while an octal is a group of 3 bits. They are represented in the table below;

Table for conversion;

Octal => binary

0 => 000

1 => 001

2 => 010

3 => 011

4 => 100

5 => 101

6 => 110

7 => 111

Hexadecimal => binary

0 => 0000

1 => 0001

2 => 0010

3 => 0011

4 => 0100

5 => 0101

6 => 0110

7 => 0111

8 => 1000

9 => 1001

A => 1010

B => 1011

C => 1100

D => 1101

E => 1110

F => 1111

(a)

(i) Convert 10011101 to hexadecimal

Step 1: Starting from the right, split the number into groups of 4s as follows;

1001 1101

Step 2: Convert each of the groups into its equivalent hexadecimal using the table above;

1001 = 9

1101 = D

Step 3: Put them together;

1001 1101₂ = 9D₁₆

(ii) Convert 10011101 to octal

Step 1: Starting from the right, split the number into groups of 3s as follows;

10 011 101

Step 2: The last group (10) in the result of step 1 above has only 2 bits. Therefore, add zero to its left to make it 3 bits as follows;

010 011 101

Step 3: Convert each of the groups into its equivalent octal using the table above;

010 = 2

011 = 3

101 = 5

Step 4: Put them together;

10 011 101₂ = 235₈

(b)

(i) Convert 00010101 to hexadecimal

Step 1: Starting from the right, split the number into groups of 4s as follows;

0001 0101

Step 2: Convert each of the groups into its equivalent hexadecimal using the table above;

0001 = 1

0101 = 5

Step 3: Put them together;

0001 0101₂ = 15₁₆

(ii) Convert 00010101 to octal

Step 1: Starting from the right, split the number into groups of 3s as follows;

00 010 101

Step 2: The last group (00) in the result of step 1 above has only 2 bits. Therefore, add zero to its left to make it 3 bits as follows;

000 010 101

Step 3: Convert each of the groups into its equivalent octal using the table above;

000 = 0

010 = 2

101 = 5

Step 4: Put them together;

00 010 101₂ = 025₈

(c)

(i) Convert 11100110 to hexadecimal

Step 1: Starting from the right, split the number into groups of 4s as follows;

1110 0110

Step 2: Convert each of the groups into its equivalent hexadecimal using the table above;

1110 = E

0110 = 6

Step 3: Put them together;

1110 0110₂ = E6₁₆

(ii) Convert 11100110 to octal

Step 1: Starting from the right, split the number into groups of 3s as follows;

11 100 110

Step 2: The last group (11) in the result of step 1 above has only 2 bits. Therefore, add zero to its left to make it 3 bits as follows;

011 100 110

Step 3: Convert each of the groups into its equivalent octal using the table above;

011 = 3

100 = 4

110 = 6

Step 4: Put them together;

11 100 110₂ = 346₈

(d)

(i) Convert 01101001 to hexadecimal

Step 1: Starting from the right, split the number into groups of 4s as follows;

0110 1001

Step 2: Convert each of the groups into its equivalent hexadecimal using the table above;

0110 = 6

1001 = 9

Step 3: Put them together;

0110 1001₂ = 69₁₆

(ii) Convert 01101001 to octal

Step 1: Starting from the right, split the number into groups of 3s as follows;

01 101 001

Step 2: The last group (01) in the result of step 1 above has only 2 bits. Therefore, add zero to its left to make it 3 bits as follows;

001 101 001

Step 3: Convert each of the groups into its equivalent octal using the table above;

001 = 1

101 = 5

001 = 1

Step 4: Put them together;

01 101 001₂ = 151₈

Homework Assignment 2 1. Consider the skeletal definition for a class called circle given as: public class Circle { private int

jek_recluse [69]

Answer:

See explaination

Explanation:

public class Circle {

private double radius;

private Location location;

private String name;

/* (non-Javadoc)

* atsee java.lang.Object#hashCode()

*/

atOverride

public int hashCode() {

final int prime = 31;

int result = 1;

result = prime * result + ((location == null) ? 0 : location.hashCode());

long temp;

temp = Double.doubleToLongBits(radius);

result = prime * result + (int) (temp ^ (temp >>> 32));

return result;

}

/* (non-Javadoc)

* atsee java.lang.Object#equals(java.lang.Object)

*/

atOverride

public boolean equals(Object obj) {

if (this == obj)

return true;

if (obj == null)

return false;

if (getClass() != obj.getClass())

return false;

Circle other = (Circle) obj;

if (location == null) {

if (other.location != null)

return false;

} else if (!location.equals(other.location))

return false;

if (Double.doubleToLongBits(radius) != Double.doubleToLongBits(other.radius))

return false;

return true;

}

NOTE: Replace all the "at" within the program with the at symbol ie shift 2.
