A variable is a quantity whose value can change. A constant is an unchanging quantity.

What are quantities whose value do not change always?
A quantity which does not change its value is called a Constant.
What do you call the quantity whose value may change depending on the given values?
Variables are called variables because they vary, i.e. they can have a variety of values. Thus a variable can be considered as a quantity which assumes a variety of values in a particular problem.An expression such as 4x3 is a variable. It can assume different values because x can assume different values.
What is quantity that changes compared to another quantity?
A rate is a comparison of the change in one quantity, such as distance, temperature, weight, or time, to the change in a second quantity of this type. The comparison is often shown as a formula, a ratio, or a fraction, dividing the change in the first quantity by the change in the second quantity.
What are the quantities whose values do not change during the execution of a program?
The entity whose value does not change during program execution are called ‘constants‘.
What is the name of a value that does not change?
Constant A value that does not change.
What is variable quantity in maths?
variable quantity – a quantity that can assume any of a set of values. variable. quantity – the concept that something has a magnitude and can be represented in mathematical expressions by a constant or a variable.
What is another name for dependent variable?
The other name for the dependent variable is the Predicted variable(s).
What is example of dependent variable?
The dependent variable is the variable that is being measured or tested in an experiment.1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.
What is another word for variables?
In this page you can discover 100 synonyms, antonyms, idiomatic expressions, and related words for variable, like: variables, unpredictable, inconsistent, change, irregular, fitful, parameter, unsteady, alterable, mutable and ticklish.
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.
Does the change in one quantity affects the other quantity?
While direct variation describes a linear relationship between two variables , inverse variation describes another kind of relationship. For two quantities with inverse variation, as one quantity increases, the other quantity decreases.So, the quantities are inversely proportional.
What do you call a comparison of two quantities with different units?
A rate is a ratio that compares two quantities with different kinds of units. For example: 120 miles in two hours. Because rates compare quantities with different units, the units must be included when writing or solving rates.
Is an entity whose value remains fixed?
An entity whose value is fixed in an expression is called a constant.
Is a variable a value that does not change?
A variable is something whose value can change. A constant is something whose value does not change.
Is a fixed value that does not change?
A symbol which has a fixed numerical value is called a constant. For example: 2, 5, 0, -3, -7, 2/7, 7/9 etc., are constants. Number of days in a week represents a constant.
What is variable and constant with example?
A constant does not change over time and has a fixed value. For example, the size of a shoe or cloth or any apparel will not change at any point. In an algebraic expression, x+y = 8, 8 is a constant value, and it cannot be changed. Variables: Variables are the terms which can change or vary over time.
What is a constant quantity?
Definitions of constant quantity. a quantity that does not vary. synonyms: constant, invariable. types: parameter, parametric quantity. a constant in the equation of a curve that can be varied to yield a family of similar curves.
What is variable quantity and constant quantity?
Measurable quantities are either variables or constants. A variable is a quantity whose value can change. A constant is an unchanging quantity.
What is the dependent quantity?
Dependent quantity: a quantity whose value depends on. another quantity. Independent quantity: a quantity whose value changes the. value of another quantity.
What is IV and DV?
An independent variable (IV) is a variable that is manipulated by a researcher to investigate whether it consequently brings change in another variable. This other variable, which is measured and predicted to be dependent upon the IV, is therefore named the dependent variable (DV).
