How do you solve word problems using variables?
Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.
What is literal equations?
A literal equation is an equation where variables represent known values. Literal equations allow us to represent things such as distance, time and interest as variables in the equation.. Using variables instead of words is a 'time saver'. For example d=rt. Meaning distance = rate and time
What does pi actually represent?
Generally, Pi is used to represent the rate of change of the circumference of a circle as it's diameter increases. This can be shown using the equation [circumference = Pi * diameter], that is the circumference of a circle is always Pi times larger than it's diameter.
How do you solve for x using a quadratic equation?
For an equation of the form ax² + bx + c = 0 you can find the values of x that will satisfy the equation using the quadratic equation: x = [-b ± √(b² - 4ac)]/2a
What is 9x2 equals 10x plus 2?
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
How do we use variables in the real wold?
Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.
What Äąs capacitance?
Capacitance is resistance (not ohms) to a change in voltage using stored charge. The differential equation of a capacitor is dv/dt = i/c. This means that the rate of change of voltage is directly proportional to current and inversely proportional to capacitance.

In order to represent a type of relationship a third table is created using the keys from the two entities being related?
That is done in a many to many relationship.
An expression in which symbols and formulae represent a chemical reaction?
A stoichiometric equation is a notation that describes a chemical reaction using chemical formulae. An example is CH4 + 2 O2 -> CO2 + 2 H2O
When both dimensions of a figure are changed using the same scale factor is the change proportional or non proportional?
If it is a 2-dimensional figure then it is proportional.
What happens to the mass if the distance stays the same and the force of gravity decreases?
assuming you are using this equation for a two body systemFgrav proportional to (m1 * m2)/dthe short answer is "one or more of the masses must decrease" to make the equation balance.If it is a diferent question, then the answer will be different.
Explain how you know that y must decrease when x decreases?
First you have to tell me what equation you are using as the basis of this relationship between x and y.
What is a decimal that does not show a repeating pattern called?
These numbers, such as pi, are known as trancendentalnumbers, because they represent a value that is not the solution of an algebraic equation or a quotient using real numbers.
What is the importance of using scale in drawing an object?
because it has to be proportional
