Students in fifth grade need to be taught how to round with mixed decimals to the nearest tenth. The prerequisites that students need before learning this concept are an understanding of place value and how to round whole numbers. There may be conceptual and procedural errors that students may have when rounding decimals to the nearest tenth. Some of these errors are that students may round the whole numbers to the nearest ten instead of the decimal portion of the problem. Another misconception is
By definition, the Universal Decimal Classification (UDC) is an indexing and retrieval language in the form of a classification for the whole of recorded knowledge, in which subjects are symbolized by a code based on Arabic numerals.[1] The UDC was the brain-child of the two Belgians, Paul Otlet and Henry LaFontaine, who began working on their system in 1889, 15 years after Melvil Dewey established the DDC.[2] Otlet and LaFontaine built their system on the foundation of the DDC with Melvil Dewey’s
Joe’s diagnostic assessment started out strong completing the two digit numbers with confidence. Moving on to the three digit numbers cracks in Joe’s understanding started to appear. Joe showed a good understanding of reading, writing and ordering two and three digit numbers. The knowledge of some more, some less and the ability of partitioning two digit numbers were also clear. Joe acknowledged that 36 less 10 is 26 because, “if you take away one bundle you
In mathematics, Pi is the symbol denoting the ratio of the circumference of a circle to its diameter. The ratio is approximately 3.14159265, pi being an irrational number (one that cannot be expressed as a simple fraction or as a decimal with a finite number of decimal places) and a transcendental number (one without continuously recurrent digits). Electronic computers in the late 20th century have carried pi to more than 100,000,000 decimal places. Using a computer program, I calculated pi into
The lack of an enterprise part numbering system is a major deficiency in our company. The data from our Product Lifecycle Management (PLM) systems indicates that our engineers located in various geographical design locations design on an average 300 parts every day. An enterprise Part Numbering System (PNS) will greatly improve the management of the constantly changing portfolio of parts in our company. It will have a far reaching impact in every aspect of our operations including supply chain management
Countless time teachers encounter students that struggle with mathematical concepts trough elementary grades. Often, the struggle stems from the inability to comprehend the mathematical concept of place value. “Understanding our place value system is an essential foundation for all computations with whole numbers” (Burns, 2010, p. 20). Students that recognize the composition of the numbers have more flexibility in mathematical computation. “Not only does the base-ten system allow us to express arbitrarily
his/her significant moves in life like change of jobs, marriage, and relocation so on and so forth. This is generally perceived as a tool for self-help. Birth Number and Name Number The birth number is calculated by adding the individual digit of the two-digit birth day number. The name number is calculated by adding up the numbers corresponding to each letter of a person’s name. Each such number also signifies a certain set of qualities and vices which is true for that particular person. Number
fast-casual food industry, continued to experience double-digit growth. The purchase of Paradise Bakery & Café added an additional 70 locations in 10 states throughout the west and southwest to Panera Bread. Recent numbers in 2013 show a total of 1,736 bakery-cafes in 45 states and also in Ontario Canada. (Panera Bread, 2014) Sales growth relative to industry Panera is a strong performer in the fast-casual industry continuing to report double-digit increases in earnings at the end of 2Q in 2013.

use and repetition of ratios and proportions as my major theme in chemistry. Throughout this sequence of instruction, my goal was for the students to seamlessly tie mathematics into the science curriculum. I wanted students to recognize the interconnectedness of the two subjects by emphasizing the association of ratios throughout chemistry and to realize the importance of ratios in real life. Ratios are found in all aspects of life and I wanted to open their eyes to this. Ratios are use in discounts
not all of the policies, that were in place during that time period. I believe the war was not justified for a number of reasons. The ratio of dead to wounded was higher than it was in the civil war which is considered one of the saddest wars in this country’s history. In the civil war, the ratio was one wounded to five killed, where as in the Philippine War, the ratio was one wounded to twelve killed. America instead of trying to peacefully resolve the situation, decided that force was a more potent

shown in Figure 2, after the dilation. My two monkeys are similar because the ratio of their lengths compared to that of the areas fits the Proportional Perimeters and Areas Theorem. Also, their corresponding angles are congruent and their corresponding lengths are proportional, proving that they are similar by definition. I can create a dilation by multiplying each coordinate with the scale factor of ½, so that the ratio of the images is 1 to 2. For example, my original monkey’s tail tip is at point
the ones that do not enable us to calculate all the unknowns by the three equations of equilibrium. 2: Hooke’s Law, Poisson’s Ratio and Modulus of rigidity. Hooke’s law, Poisson’s ratio and shear modulus (modulus of rigidity) all share a common bond. They are considered to be individually the same for a specific material. hooke’s law is formulated as F=kx; Poisson’s ratio is formulated as = (lateral strain / axial strain) and shear modulus is formulated as G= E/(2(1+" " )). 3: polar moment of inertia
Determining the Ratio of Circumference to Diameter of a Circle In determining the ratio of the circumference to the diameter I began by measuring the diameter of one of the si objects which contained circles, then using a string, I wrapped the string around the circle and compared the length of the string, which measured the circumference, to a meter stick. With this method I measured all of the six circles. After I had this data, I went back and rechecked the circumference with a tape measure

at the individual ratios seen in exhibit 1 and comparing it to the industry average shown in exhibit 2 gives a sense of where this company stands. Current ratio and quick ratio are really low and have been decreasing. For 1995, the current ratio is 1.15:1, which is less than the industry average of 1.60:1, however to give a better sense of where this stands in the industry, as seen in exhibit 3, it is actually less than the average of the bottom 25% of the industry. The quick ratio is 0.61 is less
Cash Ratio $7,195 / $152,299 = 0.05 Boot Born reported cash ratio .05 to 1. Boot Barn may have a difficulty paying its liabilities because the ratio is to low. However, Boot Barn had a net cash operation of $155,486,000.00 provided by financial activities. Boot Barn has sufficient cash to meet future financial needs. Current Ratio $203,219 / $152,299 = 1.33 Boot Barn reported a 1.33 current ratio that indicates its current possessions can cover its charges. Boot Barn will be able to pay

of those three main financial statements. It can also be defined as understanding the risk and profitability of an entity (Ready Ratios, 2013). There are different techniques of financial statement analysis including ratio analysis, vertical or common size analysis and horizontal analysis or trend analysis. Another technique sometimes applied is trend analysis of the ratio analysis (Hancock, Robinson and Bazley, 2015). The major objectives of financial statement analysis are reviewing the company’s
amount of pure citric acid required to neutralise 25cm3 of sodium hydroxide when the citric acid is 100% pure, I should easily be within the confines of my 50 cm3 burette. I will therefore now calculate the required mass of sodium hydroxide: Ratio citric acid : sodium hydroxide 1 : 3 Concentration of sodium hydroxide = 1.0 M Therefore, require concentration of citric acid = 1.0 M /3 = 0.33 M I will be using a volumetric flask which can hold 250cm3 of liquid.
