1) A variable represents an unknown value in an algebraic expression.
2) The number multiplied by a variable is the coefficient.
3) An algebraic expression uses variables, numbers, and operations.
The document discusses an introductory sociology course designed to produce informed, thoughtful citizens who demonstrate democratic values and civic participation. The course uses interactive activities, group discussions, and assignments requiring higher-order thinking to teach about diversity, social justice, and community engagement. Evaluations found the course significantly increased minority enrollment and performance while qualitative responses showed it helped students develop more open and compassionate views of others. The author questions if this pedagogy could be applied elsewhere.
This document discusses different levels of marketing competition. It outlines three levels: brand competition between similar products, substitute competition between products that fulfill similar needs, and budget competition for consumers' spending money across all products. It also describes perfect competition as a theoretical market structure where many small sellers and buyers transact standardized products and all participants are price takers. Imperfect competition refers to all other market structures that do not meet the strict conditions of perfect competition, such as monopoly, oligopoly, and monopsony. The document lists pros and cons of perfect competition, such as lower prices for consumers but insufficient profits for investment.
The document discusses measuring and calculating area. It defines area as the amount of surface enclosed by a shape. It provides formulas to calculate the area of squares, rectangles, and triangles. It also discusses converting between units of area like cm2, m2, and mm2. Examples are given of calculating the area of various shapes, including composite shapes made of multiple geometric figures. Larger areas like hectares and square kilometers are also discussed.

Este documento trata sobre la seguridad en las instalaciones eléctricas de estaciones de servicio. Explica los riesgos asociados a la electricidad como descargas eléctricas, arcos eléctricos e incendios. Detalla los requisitos para instalaciones eléctricas seguras como el uso de cables a prueba de explosiones, interruptores diferenciales, y áreas clasificadas según el riesgo. Resalta la importancia de inspecciones periódicas, equipos normalizados y capacitación del personal para prevenir accidentes.
This document discusses natural resources and defines them as things found in nature that are useful to people. It lists several examples of natural resources, including water, plants, soil, animals, fish, oil and coal. The document is intended to teach learners about natural resources and have them distinguish between natural resources and finished products. At the end, learners are asked to write a paragraph naming natural resources and defining what a natural resource is based on the information provided.
The document describes the water cycle.
1) Energy from the sun causes water to evaporate from bodies of water into water vapor in the air.
2) The water vapor condenses to form clouds.
3) Water falls from clouds as precipitation like rain or snow and flows across land or underground in a continuous cycle powered by the sun.
A graph is a visual representation of data using dots, lines, bars or other objects to show relationships between different quantities. A line graph is the best choice to track the height of a bean plant over time. The numbers "2 l 7 = 270" would represent 310, 310, 330, 350. The mode is the statistical term that best describes what is represented by the numbers in the center of the diagram showing the distribution of pro basketball players by the colleges they attended.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
The document discusses carbon and its compounds. It begins by describing the occurrence of carbon in nature and its bonding properties. Carbon has four valence electrons and forms covalent bonds by sharing electrons in order to attain stability. It then discusses the formation of single, double, and triple covalent bonds between carbon atoms and other elements like hydrogen. This allows carbon to form a huge variety of compounds through catenation and bonding with different functional groups. As a result, over three million carbon compounds are known. Isomerism is also discussed, where compounds with the same molecular formula but different structural formulas are called isomers.
This document discusses the various uses of computers in different fields such as business, banking, industry, healthcare, transportation, education, weather forecasting, home use, tourism, defense, and nuclear energy. Computers are used for tasks like e-commerce, stock trading, customer records, machinery automation, patient monitoring, flight navigation, educational resources, weather data collection, home entertainment, travel booking, digital navigation, missile targeting, and nuclear reactor control and simulation. The document provides examples of how computers facilitate functions previously done by humans across many sectors in modern society.
Shantanu Tyagi is a class 11 student at Green Feilds School. The document provides an overview of multinational corporations (MNCs), including their definition, structure, advantages, and criticisms. It discusses how MNCs have evolved over time and provides examples of large MNCs. India is highlighted as an important location for MNCs due to its large population and growing economy. Challenges faced by both foreign and domestic MNCs in India are also outlined.
