Closed Captioned Video: Algebra Applications: Variables and Equations, 3 | Closed Captioned Video: Algebra Applications: Variables and Equations, Segment 3: River Ratios Why do rivers meander instead of traveling in a straight line? In going from point A to point B, why should a river take the circuitous route it does instead of a direct path? Furthermore, what information can the ratio of the river’s length to its straight-line distance tell us? In this segment the geological forces that account for a river’s motion are explained. In the process, the so-called Meander Ratio is explored. Students construct a mathematical model of a meandering river using the TI-Nspire. Having built the model, students then use it to generate data to find the average of many Meander Ratios. The results show that on average the Meander Ratio is equal to pi. |

Definition--Ratios, Proportions, and Percents Concepts--Calculating Tax | Calculating TaxTopicRatios, Proportions, and Percents DefinitionCalculating tax involves determining the percentage amount to be added to the base price of a product or service. DescriptionCalculating tax is a fundamental application of percentages in real-world scenarios. When purchasing goods or services, the total cost is often the sum of the base price and the tax applied. Understanding how to calculate tax is essential for budgeting and financial literacy. For example, if a product costs $50 and the tax rate is 8%, the tax amount is calculated as 50 × 0.08 = 4 Therefore, the total cost is |

Definition--Ratios, Proportions, and Percents Concepts--Dimensional Analysis | Dimensional AnalysisTopicRatios, Proportions, and Percents DefinitionDimensional analysis is a method used to convert one unit of measurement to another using conversion factors. DescriptionDimensional analysis is a powerful tool in mathematics and science for converting units and solving problems involving measurements. It uses the principle of multiplying by conversion factors to ensure that units cancel out appropriately, leading to the desired unit. For example, to convert 50 meters per second to kilometers per hour, you use the conversion factors 1 meter = 0.001 kilometers and 1 hour = 3600 seconds: |

Definition--Ratios, Proportions, and Percents Concepts--Ratios in Simplest Form | Ratios in Simplest FormTopicRatios, Proportions, and Percents DefinitionRatios in simplest form are ratios that have been reduced to their smallest whole number terms. DescriptionReducing ratios to their simplest form is similar to the process of simplifying fractions, making it easier to compare and interpret data. A ratio is in simplest form when the greatest common divisor of the terms is 1. For example, the ratio 8:12 simplifies to 2:3 by dividing both terms by their greatest common divisor, 4. This skill is essential for solving problems involving proportions and understanding relationships between quantities. |
