Rustic Tastes is a brownie shop that sells 30 kinds of brownies, where brownies of thesame kind are indistinguishable, and there are at least 25 brownies of each kind. Vibrant Flavorsis a newer brownie shop that sells 40 kinds of brownies, where brownies of the same kind areindistinguishable, but there are only at least 15 brownies of each kind. Please leave your answer ina compact form, e.g. C(9, 4) instead of 126. (a) Which shop has more ways that you can get a box of 7 brownies, and by how much?(b) How many ways can you get a box of 10 brownies from Vibrant Flavors if you want to be sure to get at least 2 Citrus Central brownies and 4 Caramel Turtle brownies?(c) How many ways can you get a box of 12 brownies from Rustic Tastes if you want to get exactly 3 Basic Blondie and 3 Chocolate Melt brownies?

You need to choose a password for computer account. The rule is that the password must consist of two lowercase letter (a to z) followed by one capital letter (A to Z) followed by four digits (0, 1, …, 9). For example, the following is a valid password:Find the total number of possible passwords.
!!!FIRST READ EVERYTHING WRITTEN BELOW AND IF YOU CAN DO IT ONLY THEN START AND NO PLAGIARISM!!! Only use C++ to do this task. And I will only give thumbs up if you do not plagiarize from another Chegg or internet source. Also only if you will follow all the below instructions 100%. Only write typed answer. No handwritten. Code must visibly shows the functions and class. Attach the screenshot of output and code must be 100% complete and correct. Write a Twitter class that sets the Twitter user first (who is to be followed) and lets the client add up to 5 followers, which will be stored in an array with a capacity of 5. These users/followers could be in the form of string or Profile but both must be of same type. (Note that the followers are not stored as users, but as strings or Profiles). At any time, your main program should be able to remove any user, x from following another user, y (i.e., x is no longer in the array of followers of y). You are free to design your program as you…

Please written by computer source Unit 4 - Lab – Individual Retirement Account Calculation Assignment An Individual Retirement Account (IRA) is a special bank / brokerage account that a person can use to save money for retirement. An individual can put up to $5,500 per year tax free and the money grows tax free until the person is ready to retire. The tax rules related to IRA’s are complex, but for this assignment, we’ll assume that the person puts in the same amount of money every year (up to $5,500) and the money grows at a constant interest rate. Write a Flowgorithm program that asks the user to input an annual IRA contribution (in dollars), and interest rate (percent), and a time period (years). Calculate the value of the IRA every year for the duration of the time period provided by the user. Be sure and provide user friendly prompts. Include a comment at the beginning of the program with your name, date, and a short description of the program.
C++ Suppose we have the following declarations: struct Time { int hours; int minutes; int seconds; }; struct User { string username; string password; int userID; Time lastLogin; } newUser; User* userPtr = &newUser; Use the member selection arrow operator -> to show how you can set the lastLogin time of *userPtr to 16 hours, 43 minutes, and 39 seconds.
The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed…
