This cube root calculator might come in handy whenever you need to calculate the cube root of any given positive or negative numbers (including decimals). For a given number “a”, the cube root is the number “b” that if multiplied by itself for 3 times equals “a”. In a shorter form “b” is the cube root of “a” if b^3 = a.
Direct and inverse proportion represents the relation between two quantities. Direct and inverse proportion is one of the most important topics in class 8 …
Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝ . In fact, the same symbol is used to represent inversely proportional , the matter of the fact that the other quantity is inverted here.
How proportion calculator works? In this section, we will explain how to find proportions using a calculator? Manually, we calculate the unknown variable in a proportion by using cross multiplication method. It will come up in the next …

The Rule of Three Calculator uses the Rule of Three method to calculate the unknown value immediately based on the proportion between two numbers and the third number. The working of the Rule of Three Calculator can be expressed as follows: Here, there are two values: A and B and a value of X.
To convert cm to mm, the multiplier. is always 10. Direct proportion is used to calculate the cost of petrol or exchange rates of foreign money. The symbol for ...
Direct Proportion. If an increase in one quantity produces a proportionate increase in another quantity, then the two quantities are directly proportional to each other. or. If a decrease in one quantity produces a proportionate decrease in another quantity, then the two quantities are directly proportional to each other. Change in both the quantities must be same.
The proportion is said to be a direct proportion between two values when one is a multiple of the other. For example, 1 cm is equal to 10 mm. Here, in order to convert cm to mm, the multiplier should be 10. Direct Proportion. Two quantities a and b are said to be in direct proportion if they increase or decrease together.
Direct and inverse proportion questions involving squares, cubes and roots are not too dissimilar to the normal direct and inverse proportion questions. The only difference is that a square, cube or root is involved, and this results in there being some more steps in the working.
09.03.2010 · You can solve any proportion using the fundamental rule of proportions. First you must build the proportion if you are given a word problem. Decide using logic whether it is a direct proportion (more on one side means more on the other). If so, find the parts of the equation that use the same units and make a fraction with these, putting the smaller number …
Calculators may be used. Information The marks for each question are shown in brackets ... The time, T seconds, it takes a water heater to boil some water is directly proportional to the mass of water, m kg, in the water heater. When m = 250, T = 600 (a) Find T when m = 400
This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written: y = k x. Example: 4 people can paint a fence in 3 hours. How long will it take 6 people to paint it? (Assume everyone works at the same rate) It is an Inverse Proportion: As the number of people goes up, the painting time goes ...
