1. Rockbottom Sand and Gravel Company has contracts to deliver the following amounts of broken rock to six customers:

Customer                                 A          B          C          D          E          F

Contracted amount (tons)         1          2          6          2          3          4

Rockbottom has five trucks that may be used to make these deliveries. With the use of dividers, a truck can deliver to multiple customers, as long as it does not exceed the truck’s capacity. However, a customer’s order cannot be broken up and delivered by multiple trucks. The available trucks and their capacities are:

Truck #                         1          2          3          4          5

Capacity (tons)              4          8          4          8          6

The costs, in $000s, for each truck to deliver the required load to each customer are:

     Customer

            Truck                A          B          C          D          E          F          

                 1                  17        19        21        20        20        21

                 2                  15        18        20        18        19        23

                 3                  18        19        22        22        21        22

                 4                  15        16        19        18        18        20

                 5                  16        15        20        22        19        20

Develop a linear program to determine the delivery plan that will allow Rockbottom to minimize the cost of fulfilling their contracts.

1. Write a C++ program to check whether a number is prime or not. A prime number is a positive integer that has exactly two positive integer factors, 1 and itself. Eg: 2, 3, 5, 7, 11, 13, 17, ...

   Sample Output:
   Input a number to check prime or not: 13 The entered number is a prime number.

   Input a number to check prime or not: 28 The entered number is not a prime number.

   Enhance the program to list all factors if the number is not prime Input a number to check prime or not: 28
   The entered number is not a prime number.
   Factors: 1, 2, 4, 7, 14, and 28

A charge of -0.4 µC is located at the origin; a charge of 0.53 µC is located at x = 0.2 m, y = 0; a third charge Q is located at x = 0.32 m, y = 0. The force on the 0.53 µC charge is 4.3 N, directed in the positive x direction.

1. Determine the charge

2. With this configuration of three charges, where, along the x direction, is the electric field zero? xf=

3. x2=

Calculate the height of a column of carbon tetrachloride, CCl4(l), with a density of 1.59 g/mL that exerts the same pressure as a 15.2 cm column of Mercury, Hg(l), that has a density of 13.6 g/ml. Express your answer in meters. Please only enter the numerical value of your answer.

Packaging Solutions Corporation manufactures and sells a wide variety of packaging products. Performance reports are prepared monthly for each department. The planning budget and flexible budget for the Production Department are based on the following formulas, where q is the number of labor-hours worked in a month:

The Production Department planned to work 4,400 labor-hours in March; however, it actually worked 4,200 labor-hours during the month. Its actual costs incurred in March are listed below:

Required:

1. Prepare the Production Department’s planning budget for the month.

2. Prepare the Production Department’s flexible budget for the month.

3. Calculate the spending variances for all expense items.

How do I make a function that only prints the last one of my AVLTree ,in this case a function that only prints 44.4

And how do I make a function that only prints the first one of my AVLTree ,in this case a function that only prints 3.1

I think this can be accomplished by editing the inorder function

A sample of a concentrated fluorescent reagent was serially diluted with three steps using a variable volume 100 to 500 μL micropipetor and 10.00 mL Class A volumetric flasks. The concentrated reagent had a fluorescent signal of 653.4 and the diluted sample produced 0.057 fluorescence units. Unfortunately the steps followed for the dilution were lost. What were those steps?

Question: Air stored underground at 500 psia and 200 deg.F is first heated by natural gas combustion to 2,340 deg.F at constant pressure, then expanded in an 89% efficient turbine to atmospheric (14.7 psia) pressure. Part of the work of the turbine is used to compress ambient air at 70 deg.F and 14.7 psia to store it underground with an 85% efficient compressor. The air that is stored underground loses heat to the surroundings. The turbine powers an electric generator that is 93% efficient converting mechanical power to electrical power. Mass flow of air is 100 lb/s.

a. How much heat is added by the combustion of natural gas to the air stored underground that enters the turbine? [Answer: 513.6 Btu/lb]

b. What is the work produced by the turbine? [Answer: 379.7 Btu/lb]

c. What is the work of compression? [Answer: 260.2 Btu/lb]

d. At what temperature does the air exit the compressor? [Answer: 1154 deg.F]

e. Natural gas costs $3 per million Btu (MMBtu) and the electricity that is generated by this storage system is sold at $50/MWh. The system produces electricity from the stored compressed air for 5 hours per day. Calculate the net income from the system from electricity sales. [Answer: $2931 electricity sold, $2773 cost of natural gas, $158 net income from producing electricity 5 h/day.]
