...In the volume lab, my group and I were to perform four tasks that were all related to the measurement of the volume of fluids and solids. In the first task, we had to guess and count how many drops of water it would take to equate a milliliter. Using an eyedropper, we measured how many drops it took to get a ten milliliter graduated cylinder filled with seven milliliters of water to eight, nine, and ten milliliters, After that, we had to find the average of how many drops of water it took to raise the volume of water by one milliliter. We concluded with an average of 22 drops equating to 1 milliliter of water. The next task that my group had to do was to find the volume of three marbles by using the displacement of water. We had to fill a one...

...Lecture 5: Cost-Volume-Profit Analysis In this module, we are going to discuss a simple concept yet a powerful financial planning and decision-making tool for managers. This concept is called CVP analysis or cost volume profit relationship. Profits are the difference between revenues and costs. Both revenue and cost depend on the volume of operations. So, in the short run whether you make a profit or a loss depends upon the volume of sales you make. What is the unknown for a manager when he or she tries to project profits for future? The managers know the costs and the selling price. So the only unknown is the volume of sales. The importance of CVP analysis flows from the fact that it emphasizes the inter-relationship between costs, volume of sales, and selling price, and therefore it represents a unified picture of all financial information in a simple framework. What effect on profit can American Airlines expect when it adds a new flight on the Dallas Chicago route? How many patient days of care must Dallas Children’s hospital provide in order to cover all of its operating costs? How will the profits for Texas Instruments change if it sells 10% more of its DLP chips? Each of the above questions concerns the effect on cost and revenues when an organization’s activity changes. CVP analysis summarizes the effects of changes in organization’s volume of activities on its costs, revenue and therefore profit. Although the word profit appears in CVP analysis, this...

...Cost-Volume-Profit (CVP) Analysis Shanica N. Todd-Higgins ACC/561 - ACCOUNTING Instructor: DAVID DUREN Schedule: 06/29/2015 - 08/03/2015 Campus: COLUMBIA SOUTH CAROLINA CAMPUS Group ID: SCMBA0914 CVP - What If Analysis Through research, according to Diane Wicks (2015), “Cost-volume-profit (CVP) analysis is used to assess the impact of potential changes in costs and volume on a company's operating profit and net profit. CVP analysis is also useful in making decisions regarding pricing of products, selection of product lines and utilization of production equipments. Additionally, CVP is at the heart of methods used for calculating the break-even point and sales levels necessary to attain targeted income levels.” The break-even point according to W.D Adkins (2015) is, “the point at which revenues are just enough to cover expenses so there in no profit and no loss.” For instance Calculating Breaking-Even Analysis There are many steps in finding the break even analysis. According to Zari Ballard of Ehow (2015, ), First, calculate the total fixed costs by adding together each of the company's fixed costs. For example, a small company with annual fixed costs of $7,000 in rental payments, $3,000 in equipment leases and $30,000 in administrative salaries would have TFC of $40,000. Next, calculate the contribution margin per unit by subtracting the variable cost per unit from the sales price per unit. For example, if a small company's product sells for $60 per unit with...

...of liquid and a solid by two quantities of mass and the volume of a given quantity of matter.To properly measure density,we need container whose volume is known to a high degree of accuracy. This container is known as a flask and stopper. Introduction: Density is the ratio of the mass of a substance or object to its volume. At any given temperature, the ratio of mass to volume is characteristic for a given substance.Common liquids and solids of various densities are layered in a beaker. The liquids form different layers and the solids float at the interfaces between them. This demonstrates that a solid's ability to float or sink depends on its density relative to the liquid it is in.The physical properties of a pure substance are those that can be measured without changing the composition of the substance. The density of a substance is an intensive property of the substance. The property is independent of the mass of the substance ( intensive ). The density of a substance is a measure of the mass of the substance per volume occupied by the substance. The density of solids and liquids are generally given in units of grams per milliliter, while for gases the units are grams per liter. We will be determining the density of water, the density of an unknown liquid, the density of a regular solid and the density of an irregular solid.The Density of solid, liquid is the amount of mass it has divided by the volume it occupies. Solid has got lots of regular spaces between...

...SURFACE AREAS AND VOLUMES 239 SURFACE AREAS AND VOLUMES 13 13.1 Introduction From Class IX, you are familiar with some of the solids like cuboid, cone, cylinder, and sphere (see Fig. 13.1). You have also learnt how to find their surface areas and volumes. Fig. 13.1 In our day-to-day life, we come across a number of solids made up of combinations of two or more of the basic solids as shown above. You must have seen a truck with a container fitted on its back (see Fig. 13.2), carrying oil or water from one place to another. Is it in the shape of any of the four basic solids mentioned above? You may guess that it is made of a cylinder with two hemispheres as its ends. Fig. 13.2 File Name : C:\Computer Station\Class - X (Maths)/Final/Chap-13/Chap-13 (28th Nov. 2006) 240 MATHEMATICS Again, you may have seen an object like the one in Fig. 13.3. Can you name it? A test tube, right! You would have used one in your science laboratory. This tube is also a combination of a cylinder and a hemisphere. Similarly, while travelling, you may have seen some big and beautiful buildings or monuments made up of a combination of solids mentioned above. If for some reason you wanted to find the surface areas, or volumes, or capacities of such objects, how would you do it? We cannot classify these under any of the solids you have already studied. Fig. 13.3 In this chapter, you will see how to find surface areas and volumes of such objects. ...

...maximum volume of a box. The problem I had to solve was to take a 11x17 ½ piece of paper and turn it into a box. In order to do this, a square needs to be cut out of each corner. I had to figure out how big of a square needed to be cut out in order to create a box with the maximum volume possible. I did this by narrowing down the possibilities of the dimensions to the nearest ten thousands. (See tables attached) In order to find the maximum volume possible, I made tables using the graphing calculator. In the first column of the first table (L1), I put the size of the square that would be cut out from each corner. In L1, I started with a 1 inch square and went up to a 5.5 inch square. In the second column of the first table (L2), I put the width of the piece of paper subtracting 2 (1 for each corner) and multiplied it by L1 (11-2*L1). In the third column of the first table (L3), I did the same thing as I did in L2 using the length of the paper instead (17.5-2*L1). I used the last column (L4) of the first table to find the volumes (L1*L2*L3). (refer to the tables for widths, lengths and volumes) Using the first table, I was able to narrow down the size of the square to 2 in. Using what I found in table one, I then took the 2 in. square, went down .1 five times and up .1 five times and put that into L1 to try and narrow the size down even more. For L2, L3, and L4 of the 2nd table I repeated what I did in the 1st table to find the widths, lengths and volumes using the...

...Timber Stack Measurement It is important to estimate timber volumes accurately either in the forest or when leaving. A number of methods can be used: Crop inventory carried out by a qualified professional in the forest prior to felling It can be calculated by modern thinning machines as harvesting takes place The timber can be measured in the stacks at roadside (see method described below) Weighing of the timber as it passes though the mill gate Timber Stack Measurement Advantages It is useful to estimate timber that is stacked at roadside: It can be done quickly by the forest owner It is useful to know how much timber is leaving the forest It is useful to calculate the volume of different individual stacks, which is important if different timber products are being sold separately from the one harvesting operation Disadvantages All logs in a stack must be of uniform length and the stack should be built neatly and tidy for easy measurement and accuracy. Large stacking space is required to ensure that all harvested material can be stacked at roadside before any removal is carried out by timber trucks. Length * Width * Height = Volume (unit = m3) Some definitions Stack width The width is the specified length of the timber product in the stack. A number of sample lengths (billets) should be checked to verify the stack width. Stack length Stack length is the average length of the front and back face of the stack. The stack should be measured...

...object its often measured in grams per milliliter (g/ml). To find the density of an object you measure the number of grams it is (mass) then divide by amount of space it takes up ( volume). The final equation should look something like this, v/m=d. To find the density of the 25 objects I will use the formula volume/mass=density. Mass Mass is the quantity of matter in an object regardless of the volume or forces acting upon it. mass is a measurement of the amount of matter in an object Mass is always constant for an object no matter where the object is located The formula for mass is density X volume = mass Mass is measured in kilograms (kg), Grams (g) and milligrams (mg) Mass can be measured using scale, for example if you use an electronic scale. Put the object on the measuring scale then wit until the number stop changing and the number shown is...

...this study is to identify the density, the degree of compression which resides in a substance through the relationship between the mass the substance and its volume, of solid and liquid samples. The materials used for the liquid samples include: water, isopropyl alcohol, coconut oil and an unknown liquid. In order to determine the mass, volume and density the group measured the different samples as accurate as possible. The experimental density values were measured at 1.01 g/ml, 0.800 g/ml, 0.940 g/ml, and 0.800 g/ml respectively at room temperature. As the group calculated for the percent error, using the given formula, the result was below 3.00% for all the samples. The unknown liquid, kerosene, was identified by comparing the measured density with its theoretical value. As for the solid samples a wooden cube, rectangular plywood, a marble, and a pebble was used in the said activity. The experimental density values of the solid samples were measured at 0.500 g/cm3, 1.99 g/cm3, and 2.61 g/cm3 respectively. Finally, after accomplishing the study, the accuracy of measuring, the needed quantities and the mentioned results proved that such a great success was achieved.
