8th grade formula mini project
Algebra1 Mini-Project - Collecting Formulas
Due Date: ________________:
A formula is a literal equation that states a relationship between two or more quantities.
For this project, find two interesting formulas. Do the following for each formula.
c Write the formula as it is generally found. IF possible, write it a second time, solving for a different variable.
c Describe what the symbols represent and their units of measure.
c Describe what the formula is used for (see examples below, you may not use these formulas in your project). You may not know exactly how to manipulate the numbers or symbols, but you should be aware of the formula’s applications.
c Show the real life problem that this formula would solve and demonstrate by substituting values and finding the solution (use correct units of measurement and a correct solution).
c Final Project - save to Google Docs and share with me. We will then post to class blog.
Examples:
From Baseball: To determine a Pitcher’s Earned Run Average (ERA), the formula is
ERA = 
Where ER represents the number of earned runs that the pitcher allows during a given time, and IP represents the number of innings pitched in that time.
Curt Schilling pitched 226.2 innings and allowed 82 earned runs.
Curt’s 2004 ERA is calculated as follows:
ERA = 
From Aviation: To determine the ability of a hang glider to glide and soar, you need to find its aspect ratio (R), the formula is:
R =
Where A = area of the wing, and s is the length of the wingspan.
If a hang glider has a wing area of 36 square feet, and a wingspan of 10 feet, find it’s aspect ratio.
R =
