- 25:58 “okay, over changing quantity, anything marginal, the first line is always dash, you can see, here, for the first unit is dash, so you start from the second one, very easy, even without capital it or you can do this, just...”
- 18:32 “the cost, what will be the cost, so remember, let's assume, that's what, you are having on an error, as the worth, as a cost of a bag, and then you know, you quantity you have in the bag is worth, is 20, so for you to kn...”
- 24:19 “multiply by words, the quantity, the quantity is the same thing as the output, so it trades it to your A, okay, trades it to your A, what do you have, three, so six times three, give us what, 18, and that's how you have...”
Translating Word Problems into Equations
The lesson teaches how to translate word sentences into mathematical equations. It covers the use of variables to represent numbers and how to express word problems as algebraic expressions. Students will learn to solve simple equations and check their answers.
- 11:09 “So we say Q. And rice adds double the price of maize. That is two times Q. If she sold 50 cups of maize and 45 cups of rice, what was her income? So 50 cups of Q, that is 50 of Q, 50 Q plus-- this is 2Q plus 2Q times 45....”
- 10:21 “So our total income is 280 Nera. So if these values that we imputed, that is 50 cups. And we know the number of cups you bought and then 45 cups. Rather, if two Nera was not inclusive in this expression, if we did not gi...”
- 09:31 “And then she sold 45 cups of rice, 45 cups of rice. So 45 times two, 45 now would be 45 times four. Because a cup of rice is four Nera, so four multiplied by 45. So our income is two times 50 plus four times 45, which is...”
Fundamental and Derived Quantities
This lesson covers the definitions of fundamental and derived quantities in physics. It explains how fundamental quantities serve as the base for deriving other quantities and the importance of measurement in physical science.
- 14:11 “I've had it time without non-biased students, we say, I want to measure my weight. You can never measure your weight. What you measure is the mass. Because weight is a function of mass and acceleration due to gravity. So...”
- 25:24 “So the last one is in terms of units, the unit of mass is kilogram and that of weight is newton. Evaluation, divine, fundamental and the life quantity in your own language to the best of your knowledge. So explaining tha...”
- 07:06 “units. So this table doesn't show completely the number of the life quantity and their units, so we only is limited. As I said, there are numerals, there are in a Zostibu number of these derived quantity. So the first on...”
Revenue Types
This lesson defines revenue and explains its three main types: total revenue, average revenue, and marginal revenue. It covers how to calculate each type and their relationships to production and sales.
- 05:10 “So, let's get the words, the solution to these words, so this interesting question won't have to the other. Look at the board, here you have what, P is on the wall, it's first on the CR, remember the formula I give to us...”
- 02:40 “The average revenue will be given to you in the world and the question, are we together? Then, to get your average revenue, your average revenue is worth is your total revenue, okay? Divide that worth the quantity that h...”
- 11:28 “which is what, change in CR over change in quantity, so what do I do, I would say, this minus this, that's 24, minus 28, it's over, what's the quantity, it's minus 7, it's minus 7, okay, so what do I do, transform minus...”
