1. How do I calculate the area/volume of a shape?
To calculate the area of a shape, use the formula for that specific shape. For example, to find the area of a rectangle, use the formula A = length x width. To find the volume of a shape, use the formula for that specific shape. For example, to find the volume of a cube, use the formula V = length x width x height.
2. How do I convert units?
To convert units, use the appropriate conversion factor. For example, to convert from meters to feet, multiply by 3.28. Make sure to cancel out units to ensure the correct conversion.
3. How do I calculate percentages?
To calculate percentages, divide the part by the whole and multiply by 100. For example, if you want to find what percentage 25 is of 100, divide 25 by 100 and multiply by 100 to get 25%.
4. How do I find the slope of a line?
To find the slope of a line, use the formula (y2 - y1) / (x2 - x1). This will give you the change in y over the change in x, or the rise over run.
5. How do I calculate density?
To calculate density, use the formula D = mass / volume. Make sure to use the correct units for mass (grams) and volume (cubic centimeters) to get the density in units of grams per cubic centimeter.
