The multiplier used to increase a value by a certain percentage. For example, the multiplier for a 10% increase is 1.10, which is obtained by dividing 110% by 100.

The overall percentage increase when multiple percentage increases are applied consecutively. It is calculated by multiplying the individual multipliers together.

A measure that combines two different units, often used to describe quantities such as speed, density, and pressure. It is expressed as a ratio of two units.

The rate at which an object moves, calculated by dividing the distance traveled by the time taken.

The amount of matter contained in a given volume. It is a measure of how tightly packed matter is in a substance. It can be calculated by dividing mass by volume.

The space occupied by a three-dimensional object, calculated by multiplying its length, width, and height. It is often expressed in cubic units (cm3, m3).

The amount of matter in an object, often expressed in grams (g).

A type of interest that is calculated on the principal amount plus any accumulated interest from previous periods. It leads to exponential growth over time.

Pressure is defined as the force applied per unit area.

Direct proportion means that as one quantity increases, the other quantity increases at the same rate, and their ratio remains constant.

The formula for pressure is Pressure = Force / Area.

Direct proportion can be represented by the formula y = kx, where k is the constant of proportionality.

Direct Proportion graphs are always straight lines passing through the origin (0,0).

To find the multiplier (k) in a direct proportion, divide the value of y by the corresponding value of x.

To convert units, use the relationship between the two units.

When two quantities are directly proportional, they have a common multiplier which is a constant.

A relationship where one variable increases as another variable decreases at a constant rate. For example, if the speed of a car increases, the time it takes to travel a certain distance decreases proportionally.

The constant factor that relates two variables in a direct proportion. It represents the ratio of change between the variables.

A type of direct proportion where one variable is proportional to the square of another variable. For example, the area of a square is proportional to the square of its side length.

A type of direct proportion where one variable is proportional to the square root of another variable. For example, the time it takes for a pendulum to swing back and forth is proportional to the square root of its length.

The equation that represents the relationship between two variables in a direct or inverse proportion. It typically includes the multiplier (k) and the variables involved.

In direct proportion, if one variable increases by a factor, the other variable increases by the same factor. In inverse proportion, if one variable increases by a factor, the other variable decreases by the same factor.

To write down an equation representing the relationship between two variables in direct or inverse proportion. It requires identifying the type of proportion, the multiplier (k), and the variables involved.
