Assn #54 - Proportions Tables

Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other is constant.

Front

How can you determine if a table is proportional?

Back

A table is proportional if the ratios of the corresponding values are equal.

Front

What does it mean if a table is non-proportional?

Back

A non-proportional table has varying ratios between the corresponding values, meaning they do not maintain a constant ratio.

Front

If Sherissa puts 3 quarters in her bank each day, how many quarters will she have after 5 days?

Back

15 quarters (3 quarters/day * 5 days = 15 quarters).

Front

What is the formula to find the total number of items in a proportional relationship?

Back

Total = Rate * Time (or Number of Days).

Front

How many line segments are needed to draw 1 hexagon?

Back

6 line segments.

Front

If 3 hexagons require 18 line segments, how many line segments does each hexagon require?

Back

6 line segments per hexagon (18 line segments / 3 hexagons = 6 line segments/hexagon).

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities.

Front

If a table shows values (2, 4), (3, 6), and (4, 8), is it proportional?

Back

Yes, it is proportional because the ratios (y/x) are all equal (2, 2, 2).

Front

What is an example of a non-proportional relationship?

Back

An example is a table showing (1, 2), (2, 5), (3, 7) where the ratios are not constant.
