The following pseudocode describes how a widget company computes the price of an order from the total price and the number of the widgets that were ordered. Read the number of widgets. Multiple the number of widgets by the price per widget of 9.99. Compute the tax (5.5 percent of the total price). Compute the shipping charge (.40 per widget). The price of the order is the sum of the total widget price, the tax, and the shipping charge. Print the price of the order
Answer:
The program in Python is as follows:
widget = int(input("Widgets: "))
price = widget * 9.9
tax = price * 0.55
ship = price * 0.40
totalprice = price + tax + ship
print("Total Price: $",totalprice)
Explanation:
The question is incomplete, as what is required is not stated.
However, I will write convert the pseudocode to a programming language (in Python)
Get the number of widgets
widget = int(input("Widgets: "))
Calculate price
price = widget * 9.9
Calculate the tax
tax = price * 0.55
Calculate the shipping price
ship = price * 0.40
Calculate the total price
totalprice = price + tax + ship
Print the calculated total price
print("Total Price: $",totalprice)

Create a list of lists, named hamsplits, such that hamsplits[i] is a list of all the words in the i-th sentence of the text. The sentences should be stored in the order that they appear, and so should the words within each sentence. Regarding how to break up the text into sentences and how to store the words, the guidelines are as follows: Sentences end with '.', '?', and '!'. You should convert all letters to lowercase. For each word, strip out any punctuation. For instance, in the text above, the first and last sentences would be: hamsplits[0] == ['and', 'can', 'you', 'by', ..., 'dangerous', 'lunacy'] hamsplits[-1] == ['madness', 'in', 'great', ..., 'not', 'unwatchd', 'go']
Answer:
Explanation:
The following code is written in Python. It takes in a story as a parameter and splits it into sentences. Then it adds those sentences into the list of lists called hamsplits, cleaned up and in lowercase. A test case is used in the picture below and called so that it shows an output of the sentence in the second element of the hamsplits list.

Regarding the role played by the “victim” in deadlock resolution, give an example of such a deadlock in real life and explain your answers to these questions.
a. Describe how you might choose the victim to be removed and the consequences, both positive and negative, of that removal.
b. Describe the fate of the victim and the chances of eventually completing its processing.
c. Describe the actions required, if any, to complete the victim’s tasks.
Answer:
Here the answer is given as follows,
Explanation:
The real-life situation of a deadlock resolution where a role is played by the victim is given as follows:
Example: An example of such a situation are often a one-way lane where the flow of traffic is merely in a method. Thus, on just one occasion, the flow of traffic can enter one direction only. Each entrance/exit gate is often considered a resource. during this case, if two cars are coming from both the entrances and that they are often considered as two tasks, then one among the cars must copy or we will say hand over its resource in order that the opposite car gets the prospect to first cross the lane or we will say the opposite task gets executed.
a) Victim: The steps which describe how a victim is chosen are given as follows :
The task which is terminated so as to interrupt things of deadlock is taken into account because of the victim.
There are often a variety of job pools that will be under a deadlock situation and therefore the victim is usually a low-priority task in order that the performance isn't affected that much and termination of this task doesn't cause any effect on the opposite jobs.
the main positive effect of selecting and terminating a victim is that things of deadlock are resolved and every one of the tasks can execute now.
The negative effect is that the task that's chosen because the victim is terminated and is executed at the previous. This whole process for choosing a victim then terminating it then restarting it again may consume some longer also.
b) An easy deadlock priority is often set. this suggests that the victim’s task or the task is often terminated so as to interrupt the deadlock and other jobs can finish executing. After this, the task which is terminated are often later restarted and every one of the tasks can then execute without a deadlock.
c) When employment gets terminated, the knowledge associated with it's stored. Are often This is often done in order that the work can be restarted again and therefore the information in it's not lost. Since the progress of the victim is stopped. Thus, the sole thanks to complete the victim’s task would be to start out it again. But before restarting the task, this must be considered that the victim’s task doesn't cause any deadlock within the system.

Isaac Newton devised a clever method to casily approximate the square root of a number without having
to use a calculator that has the square root function. Describe this method with illustration
Answer:
The illustration in Java is as follows:
import java.util.*;
import java.lang.Math.*;
class Main{
public static void main (String[] args){
Scanner input = new Scanner(System.in);
double num, root, temp;
num = input.nextDouble();
temp = num;
while (true){
root = 0.5 * ( (num / temp)+temp);
if (Math.abs(root - temp) < 0.00001){
break; }
temp = root; }
System.out.println("Root: "+root);
}}
Explanation:
This declares all necessary variables
double num, root, temp;
This gets input for num (i.e the number whose square root is to be calculated)
num = input.nextDouble();
This saves the input number to temp
temp = num;
This loop is repeated until it is exited from within the loop
while (true){
Calculate temporary square root
root = 0.5 * ( (num / temp)+temp);
The loop is exited, if the absolute difference between the root and temp is less than 0.00001
if (Math.abs(root - temp) < 0.00001){
break; }
Save the calculated root to temp
temp = root; }
This prints the calculated root
System.out.println("Root: "+root);

The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 1.501 g sample of BHT was combusted in an oxygen rich environment to produce 4.497 g of CO2(g) and 1.473 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT.
Answer:
C15H24O
Explanation:
n(C) = 4.497 g/44g/mol = 0.1022
Mass of C = 0.1022 × 12 = 1.226 g
n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles
Mass of H = 0.0823 × 2 ×1 = 0.165g
Mass of O= 1.501 -(1.226 + 0.165)
Mass of O= 0.11 g
Number of moles of O = 0.11g/16g/mol = 0.0069 moles
Dividing through by the lowest ratio;
0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069
15, 24, 1
Hence the formula is;
C15H24O
Answer
The formula is C1SH240

In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value. Write a C# program named DoubleDecimalTest that declares and displays two variables—a double and a decimal. Experiment by assigning the same constant value to each variable so that the assignment to the double is legal but the assignment to the decimal is not.
Answer:
The DoubleDecimalTest class is as follows:
using System;
class DoubleDecimalTest {
static void Main() {
double doubleNum = 173737388856632566321737373676D;
decimal decimalNum = 173737388856632566321737373676M;
Console.WriteLine(doubleNum);
Console.WriteLine(decimalNum); } }
Explanation:
Required
Program to test double and decimal variables in C#
This declares and initializes double variable doubleNum
double doubleNum = 173737388856632566321737373676D;
This declares and initializes double variable decimalNum (using the same value as doubleNum)
decimal decimalNum = 173737388856632566321737373676M;
This prints doubleNum
Console.WriteLine(doubleNum);
This prints decimalNum
Console.WriteLine(decimalNum);
Unless the decimal variable is commented out or the value is reduced to a reasonable range, the program will not compile without error.

You are a high school student learning about computers and how to build them. As a class project, you have built a new computer. You power on your computer and begin to configure the system. After a short while, you notice smoke coming from the PC, and shortly after that, the computer stops working. After removing the computer case, you see that the CPU and surrounding areas are burnt and very hot. You realize that the costly mistake you made was not using a heat sink. When rebuilding your computer, which cooling systems would MOST efficiently remove heat from the CPU?
Answer:
You can use thermal paste, active heat sink, liquid pipes, and even a fan. These are just some that I've heard.
Explanation:
All of these are cooling and will stop the Central Processing Unit from overheating.
Hope this helps :)
When rebuilding your computer, the cooling systems which would most efficiently remove heat from the Central processing unit (CPU) are: cooling fan and thermal compounds.
A computer refers to an intelligent electronic device that is designed and developed to receive raw data as an input and then processes these data into an information (output) that is usable by an end user.

Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or intersect. The method accepts the coordinates of the center of the first circle and its radius, and the coordinates of the center of the second circle and its radius.
The header of the method is as follows:
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2)
Hint:
Distance between centers C1 and C2 is calculated as follows:
d = Math.sqrt((x1 - x2)2 + (y1 - y2)2).
There are three conditions that arise:
1. If d == r1 + r2
Circles touch each other.
2. If d > r1 + r2
Circles do not touch each other.
3. If d < r1 + r2
Circles intersect.
Answer:
The method is as follows:
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){
double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));
if(d == r1 + r2){
System.out.print("The circles touch each other"); }
else if(d > r1 + r2){
System.out.print("The circles do not touch each other"); }
else{
System.out.print("The circles intersect"); }
}
Explanation:
This defines the method
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){
This calculate the distance
double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));
If the distance equals the sum of both radii, then the circles touch one another
if(d == r1 + r2){
System.out.print("The circles touch each other"); }
If the distance is greater than the sum of both radii, then the circles do not touch one another
else if(d > r1 + r2){
System.out.print("The circles do not touch each other"); }
If the distance is less than the sum of both radii, then the circles intersect
else{
System.out.print("The circles intersect"); }

What would be the result of the flooding c++ cide assuming all necessary directive
Cout <<12345
Cout<
cout <
Cout<< number <
Answer:
See explanation
Explanation:
The code segment is not properly formatted; However, I will give a general explanation and a worked example.
In c++, setprecision are used to control the number of digits that appears after the decimal points of floating point values.
setprecision(0) means; no decimal point at all while setprecision(1) means 1 digit after the decimal point
While fixed is used to print floating point number in fixed notation.
Having said that:
Assume the code segment is as follows:
number = 12.345;
cout<<fixed;
cout<<setprecision(0);
cout<<number <<endl;
The output will be 12 because setprecision(0) implies no decimal at all; So the number will be rounded up immediately after the decimal point
