Proportional Relationships from Verbal Descriptions When given a verbal description that compares quantities, we can write ratios and then compare them to determine if they are proportional. Marz …

A ratio is a relationship between two numbers that defines the quantity of the first in comparison to the second. For example, for most mammals, the ratio of legs to noses is ...

Hubble’s law is an observed relationship between the distance to far-off objects in the universe and the speed with which they are moving away from us. These observations tell us that the universe is …

Hooke's law is an empirical physical law describing the linear relationship between the restorative force exerted by a spring and the distance by which the spring is displaced from its equilibrium …

Thus, the volume of the gas is proportional to the number of gas particles. If pressure and temperature of an ideal gas is kept constant then volume of container is directly proportional to the amount of gas …

Interpreting Rates of Change from Graphs The slope of a line shows the rate of change in a linear relationship. For example, the graph below shows a rate of change of 10 liters per second. The slope …

When we say that a variable varies directly as another variable, or is directly proportionate to another variable, we mean that the variable changes with the same ratio as the other variable increases. …

In mathematics, we say that two objects are similar if they have the same shape, but not necessarily the same size. This means that we can obtain one figure from the other through a process of expansion …

We say two quantities are in the golden ratio if their ratio is equivalent to the ratio of the sum of the quantities to the larger of the two quantities. It is obtained by dividing a line into two parts such that …

6 days ago · However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which postulates that gravity is a force where two bodies of mass are directly drawn or …
