Two examples are given, one showing a profit and one a loss. Students are instructed to complete homework problems calculating profit and loss, including using percentages.
Math Lesson 6
This document is a lesson on simple and compound interest. It begins with an introduction and then defines the formulas for simple and compound interest. For simple interest, the formula is Interest = Principal x Rate x Time. For compound interest, the formula is Amount = Principal x (1 + Rate/Number of times compounded)^(Number of times compounded x Time). The document provides examples of calculating simple and compound interest based on investing or saving different principal amounts over various time periods at given interest rates. It concludes by assigning homework to calculate the amount of interest earned on an account over 2 years.

1) Students will be able to explain geometric patterns.
2) Students can solve problems involving patterns.
3) Students will draw patterns.
Examples of simple number and geometric patterns are presented, including a flower bed pattern where the number of patio stones can be described by the formula Patio stones = 3 + 7n. Students are assigned homework to solve exercises involving finding patterns and differences in sequences.
Math Lesson 2
This document is a lesson plan on geometric patterns that includes:
1) An introduction to the topic of geometric patterns and learning outcomes of being able to explain, solve problems about, and draw patterns.

Finally, it briefly introduces the concepts of space, time and matter.
Physics class 10
This document discusses the different branches of physics and their relationship to physical quantities like space, time, and matter. It aims to help students understand the connections between physics and other fields like healthcare, agriculture, technology, social science, and astronomy. The key physical quantities discussed are space, time, and matter. Students are asked to write down their basic understanding of these physical quantities.
Physics class 8
1. The document discusses fundamental and derived units of measurement and the fundamental rules of measurement.
2. It explains that fundamental units include units of length, time, mass, and temperature while derived units are combinations of fundamental units.
3. The document outlines several systems of measurement including the CGS, FPS, MKS, and SI (metric) systems which define the fundamental standards.
Physics class 5
1. Errors in measurement include instrumental errors, observational errors, random errors, and systematic errors.
2. Instrumental errors arise from defects in measurement instruments and include zero errors, backlash errors, and level errors.
3. Observational errors are due to personal factors of the observer and conditions of observation.
4. Random errors occur unpredictably while systematic errors are due to defects in instruments or measurement methods and produce consistent bias.
5. The accurate value of a measured quantity accounts for the measurement error and can be calculated using formulas provided.
