In this short video we will write a ratio based on a real world situation.

In this video, the teacher explains how to solve ratio problems using a ratio table. The example given is about determining the number of blue cars in a parking lot based on a given percentage. The teacher demonstrates how to fill out...

Introductory lesson on the Hedgehog Signalling Pathway in Invertebrates. The Hedgehog signaling pathway is important in embryological development of both invertebrates and vertebrates. Hedgehog proteins facilitate the activation of the...

👉 Learn how to solve for the length of the sides and the measures of the angles of a triangle using the law of sines. The law of sines is used in determining the length of the opposite side to a known angle measure or the measure of the...

In this short video, we will solve a standardized test question about finding rate in miles per hour. We will learn that rate is a ratio. A ratio that is divided will become a unit rate or miles per one hour.

David Hasslehoff did chemistry?! No wait, Hasselbalch. And Henderson. Anyway there's this equation, and it relates the pH of a buffer solution to the pKa of the acid and the ratio of the concentrations of the acid and conjugate base....

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 1H Q2, which covers proportions and rates of change in ratios. In the problem, learners are required to work out the number of adults in a group,...

Explore five different strategies for solving ratio problems. The strategies include using tables with addition or multiplication, double number lines, tape diagrams, and graphing. The teacher emphasizes that there is no one right way to...

👉 Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric equations, they include by factoring out the GCF and simplifying the factored equation. Another method is to use a...

Understand a ratio and use it to compare two quantities.

We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the rates of effusion for two gases using Graham's law, and we can...
