3.3 REVIEW: Similar Figures, Scale, Simple Interest, & Net Worth

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is scale in a drawing?

Back

Scale is the ratio of a distance on a drawing or model to the corresponding distance in reality. For example, a scale of 1 inch to 15 yards means 1 inch on the drawing represents 15 yards in real life.

Front

How do you calculate net worth?

Back

Net worth is calculated by subtracting total liabilities (debts) from total assets (what you own). Net Worth = Total Assets - Total Liabilities.

Front

What is simple interest?

Back

Simple interest is calculated on the principal amount only. The formula is: Simple Interest = Principal x Rate x Time.

If a soccer field is 645 yards wide, how wide is it in a scale drawing with a scale of 1 inch = 15 yards?

Back

To find the width in the drawing, divide the actual width by the scale: 645 yards ÷ 15 yards/inch = 43 inches.

Front

What does it mean if a net worth statement shows a negative value?

Back

A negative net worth indicates that total liabilities exceed total assets, meaning the individual owes more than they own.

Front

What is the formula for calculating simple interest?

Back

The formula for calculating simple interest is: I = PRT, where I is interest, P is principal, R is rate (as a decimal), and T is time (in years).

Front

If Brooklyn's net worth is $4,623, what does this represent?

Back

Brooklyn's net worth of $4,623 represents the total value of her assets after subtracting her liabilities.

Front

What is the significance of corresponding angles in similar figures?

Back

Corresponding angles in similar figures are equal, which helps to establish that the figures are similar.

Front

How do you convert a scale drawing back to actual size?

Back

To convert a scale drawing back to actual size, multiply the measurement on the drawing by the scale factor.
