What are the example of direct proportion?
Length in metres and length in feet. Speed and distance travelled in a fixed amount of time at that speed.
What are the 4 types of proportion?
direct proportion indirect proportion additive proportion partitive proportion
What is the difference between direct proportion and indirect proportion?
Two variables are said to be in direct proportion if, when you increase one by some multiple, the other also increases by that same multiple. Alternatively, both decrease by the same proportion. Two variables are in indirect (or inverse) proportion if an increase in one of them is associated with a decrease in the other, and conversely. The proportional change in both is the same. For example, if I change the speed at which I am driving, then the distance that I can cover in a fixed amount of time will change in the same proportion. Double my speed then double the distance, quadruple speed and quadruple distance, halve the speed and halve the distance. So speed and distance are directly proportional. Now think of speed and the time taken to do a fixed distance. Double my speed and halve the time. Halve the speed then double the time. So time taken is inversely proportional to speed.
What is an inverse proportion?
Two variables are said to be in inverse proportion if their product is a constant.So, if X and Y are in inverse proportion, thenXY = k or Y = k/X for some constant k.If you double X then Y is halved. If you decrease X by a factor of 3 then Y is trebled.A common example is Speed and Time for covering a fixed Distance.
What is the rule of constant proportions?
The law of constant proportions, also called Proust's law, states that the elements in a compound are all present in a fixed proportion by weight, regardless of how the compound is prepared.
What is the name of two or more elements in a fixed proportion?
A compound refers to two or more elements chemically bonded together in a fixed proportion. This fixed proportion is represented by a chemical formula that shows the types and ratios of atoms present in the compound.
Is the proportion of iron and sulfur in a mixture is always fixed?
No, the proportion of iron and sulfur in a mixture is not always fixed. It can vary depending on the composition of the mixture and how it was prepared. The proportion can be adjusted by changing the quantities of iron and sulfur added to the mixture.
If a material contains three elements joined in a fixed proportion it is a(an)?
A material that contains three elements joined in a fixed proportion is a pure substance called a compound. It is not a mixture.
Is the proportion of iron and sulfur in a mixture always fixed?
Yes
What is high gearing?
A high proportion of fixed interest funding.
Total variable cost does not increase in proportion to output is it true?
False, it is the fixed cost which is not increased or decreased with proportion to output.
What are two or more elements combined in a fixed proportion form?
compounds
Do mixture combine in set or fixed pattern?
No mixture has no definite proportion
If a material contains three elements but not joined in a fixed proportion it is a(an)?
It is a mixture.
If a material contains three elements but not joined in a fixed proportion it is a?
It is a mixture.
What is compound and a example?
compound contains elements in a fixed proportion. Example= NaCl
What are two or more substances that are chemically combined in a fixed proportion called?
