(Package Inheritance Hierarchy) Package-delivery services, such as FedEx®, DHL® and UPS®, offer a number of different shipping options, each with specific costs associated. Create an inheritance hierarchy to represent various types of packages. Use class Package as the base class of the hierarchy, then include classes TwoDayPackage and OvernightPackage that derive from Package.

Base-class Package should include data members representing the name, address, city, state and ZIP code for both the sender and the recipient of the package, in addition to data members that store the weight (in ounces) and cost per ounce to ship the package. Package’s constructor should initialize these data members. Ensure that the weight and cost per ounce contain positive values. Package should provide a public member function calculateCost that returns a double indicating the cost associated with shipping the package. Package’s calculateCost function should determine the cost by multiplying the weight by the cost per ounce.

Derived-class TwoDayPackage should inherit the functionality of base class Package, but also include a data member that represents a flat fee that the shipping company charges for two-day-delivery service. TwoDayPackage’s constructor should receive a value to initialize this data member. TwoDayPackage should redefine member function calculateCost so that it computes the shipping cost by adding the flat fee to the weight-based cost calculated by base class Package’s calculateCost function.

Class OvernightPackage should inherit directly from class Package and contain an additional data member representing an additional fee per ounce charged for overnight-delivery service. OvernightPackage should redefine member function calculateCost so that it adds the additional fee per ounce to the standard cost per ounce before calculating the shipping cost. Write a test program that creates objects of each type of Package and tests member function calculateCost.

6. Ending Finished Goods Inventory was supposed to be $200,000. It was actually $50,000. What could have caused inventory to be so low? What could be done to correct the situation? List as many reasons as you can. Use complete sentences and good grammar.

Blocks A (mass 3.50 kg ) and B (mass 8.00 kg ) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 2.00 m/s . The blocks are equipped with ideal spring bumpers. The collision is head-on, so all motion before and after the collision is along a straight line. Let +x be the direction of the initial motion of block A.

Find the maximum energy stored in the spring bumpers.

Find the velocity of block A when the energy stored in the spring bumpers is maximum.

Find the velocity of block B when the energy stored in the spring bumpers is maximum.

Find the velocity of block A after they have moved apart.

Find the velocity of B after they have moved apart.

Norwall Company’s budgeted variable manufacturing overhead cost is $1.40 per machine-hour and its budgeted fixed manufacturing overhead is $57,288 per month.

The following information is available for a recent month:

1. The denominator activity of 20,460 machine-hours is used to compute the predetermined overhead rate.
2. At a denominator activity of 20,460 machine-hours, the company should produce 9,300 units of product.
3. The company’s actual operating results were:

Required:

1. Compute the predetermined overhead rate and break it down into variable and fixed cost elements. (Round your answers to 2 decimal places.)

2. Compute the standard hours allowed for the actual production.

3. Compute the variable overhead rate and efficiency variances and the fixed overhead budget and volume variances.

A solution is made using 16.5 percent by mass CH₂Cl₂ in CHCl₃. At 30 °C, the vapor pressure of pure CH₂Cl₂ is 490 mm Hg, and the vapor pressure of pure CHCl₃ is 260 mm Hg. The normal boiling point of CHCl₃ is 61.7 °C.

B.what is the vapor pressure of the solution

C. what is the molarity of CH2Cl2 in solution

D. what is the boiling point of the solution? (Kb for CHCl3 is 3.67 C/m)

Campus Package Delivery (CPD) provides delivery services in and around Paradise. Its profits have been declining, and management is planning to add an express service that is expected to increase revenue by $50,000 per year. The total cost to lease the necessary additional package delivery vehicles from the local dealer is $7,500 per year. The present manager will continue to supervise all services at no increase in salary. Due to expansion, however, the labor costs and utilities would increase by 50 percent. Rent and other costs will increase by 20 percent. Required: a. Prepare a report of the differential costs and revenues if the express service is added. (Enter loss amount with minus sign.)

If 7.45 g of N2 and 4.20 g of O2 react according to: 2 N2(g) + O2(g) → 2 N2O(g)

a) Which reactant is in excess?

b) Calculate the mass of product formed.

3. Arcylonitrile, C3H3N, is the starting material for the production of a kind of synthetic fibre. It can be made from propylene, C3H6, by reaction with nitric oxide, NO, as follows: 4 C3H6(s) + 6 NO(g) → 4 C3H3N(s) + 6 H2O(l) + N2(g)

What mass of C3H3N can be made when 21.6 g of C3H6 react with 21.6 g of nitric oxide? Identify the limiting reactant in the reaction.

Using C++, develop a project that uses the various concepts you have learned over the course the term. The purpose of this project is to understand important data structures and learn how to implement them so that improve programming skills as well. Your final deliverable can be a program to do some type of useful computation. It can be a retail management system that keeps track of the daily delivery orders by customers; or a clinic reservation system that bookkeeps patient information and manages bookings. These are ideas to help you find a project, not to restrict you; in other words, if you want to do something substantial and interesting (and has the required features described below), but it does not strictly fall into one of these categories, you may still do that.

My subject is data structure

Your project must have each of the following features:

1) It must use an efficient algorithm for sorting or searching or both, for some aspect of the project.

2) It must involve a linked-list implementation (e.g., stack, queue, etc.).

3) It must involve an implement of the binary tree ADT using a linked-list
