In this short video, we will solve a standardized test question by writing a proportion. We will identify key terms and review proportional relationships.

In a new rule about coverage of contraception, the Trump administration argues that birth control is bad for your health. But it's a claim that doesn't stand up to scrutiny. That's the topic of this week's Healthcare Triage.

👉 Learn how to determine if a given SSA triangle has 1, 2 or no possible triangles. Given two adjacent side lengths and an angle opposite one of them (SSA or ASS), then there are 3 possible cases: there can be 1 solution, 2 solutions and...

👉 Learn how to solve rational equations. A rational expression is an expression in the form of a fraction where the numerator and/or the denominator are/is an algebraic expression. There are many ways to solve rational expressions, one...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

👉 Learn how to solve problems using percents. When solving problems with percents we will either convert the percents to decimal form or use proportions to solve. We will look to solve for the percent of change, the original price,...

This video is a lecture on how to calculate percentage changes, which is a crucial skill in the field of economics for dealing with large and significant numbers. The lecturer explains the definition of a percentage, how to calculate...

👉 Learn how to solve with the ratio of sides and angles of a triangle. Given the ratio of the sides of a triangle and the perimeter of the triangle, we can solve for the actual lengths of the triangle. Similarly, when the ratio of the...

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we...

ACT SAT PREP Learn how to determine the final weight given a ratio of weights

In this video, the teacher explains how to determine if two circles are similar using translations and dilations. They define similarity as having congruent corresponding angles and proportional corresponding sides. The video provides...
