20. Compute mowing time Problem: A program is required to read from the screen the length and width of a rectangular house block, and the length and width of the rectangular house that has been built on the block. The algorithm should then compute and display the mowing time required to cut the grass around the house, at the rate of two square meters per minute. Work out the algorithm using pseudo code. Rearrange the following lines to suit the requirements. house_area = house_length* house_width Output mowing_time to screen Calculate_mowing_time block_area = block_length* block_width Get house_length, house_width END Get block_length, block_width Prompt operator for block_length, block_width mowing_area = block_area-house_area mowing_time = mowing_area/2 Prompt operator for house_length, house_width Implement the program in Java.

1. Design an algorithm to find the weighted sum of four test scores (https://en.wikipedia.org/wiki/Weight_function). Assume that the weights have been accurately calculated in advance such that their sum equals one. Your algorithm must-read in the four test scores and four corresponding weights in the following order: score1 weight1 score2 weight2 score3 weight3 score4 weight4 Write your algorithm such that it can be run with any set of data values. However, you can test your algorithm on the following sample data to verify that the result is 70: 90 0.10 80 0.20 70 0.30 60 0.40 2.

In JAVA code (Bubble Sort): 1. Prepare a data set containing 10,000 integers (random). 2. Make a code that will create 3 variants of the data: one in best case (data are arranged in ascending order); the other in worst case (data are arranged in descending order); and the last in average case (data are randomly arranged). 3. Each integer is considered as one input in the code. 4. The output of your program should be the number of statements executed in the process of sorting for each of the algorithms. This, therefore, means that you have to embed a counter variable in your program that keeps track of the number of statements executed in the sorting part of your code. 5. The end value of the variable shall be the output of your program.
8.27 LAB: Scrabble points Scrabble is a word game in which words are constructed from letter tiles, each letter tile containing a point value. The value of a word is the sum of each tile's points added to any points provided by the word's placement on the game board. Write a program using the given dictionary of letters and point values that takes a word as input and outputs the base total value of the word (before being put onto a board). Ex: If the input is: PYTHON the output is: 14 python tile_dict = { 'A': 1, 'B': 3, 'C': 3, 'D': 2, 'E': 1, 'F': 4, 'G': 2, 'H': 4, 'I': 1, 'J': 8, 'K': 5, 'L': 1, 'M': 3, 'N': 1, 'O': 1, 'P': 3, 'Q': 10, 'R': 1, 'S': 1, 'T': 1, 'U': 1, 'V': 4, 'W': 4, 'X': 8, 'Y': 4, 'Z': 10 }

Exercise #3 o Write a program averageLuminance(picture) which takes as input a picture uses functional programming to calculate the average luminance of the picture’s pixels. Use the helper function def luminance(pixel): r = getRed(pixel) g = getGreen(pixel) b = getBlue(pixxel) y = 0.2126 * r + 0.7152 * g + 0.0722 * b return y Within your main program, use map and luminance to create a list of luminances from the list of pixels.

Please help with this c++ problem Assignment 6 - Monkey Food In the Gaddis textbook read Chapter 8 sections 8.1-8.9 before starting this assignment. This assignment is Programming Challenge 4 from Chapter 8 of the textbook. A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 x 7 arrray, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey from the keyboard. The number of pounds of food eaten by one monkey in one day should be a floating-point value. Input Validation: Do not accept negative numbers. Then your program should create a report that includes the following information: A nicely-formatted table with a row for each monkey and a column for each day of the week showing the amount of food eaten by that monkey on that day.
