What is 2.072 to two significant figures?
To find a number to two significant figures or any amount of significant figures you look at one plus the amount of asked figures, in this case the third significant figure, and if it is 5 or greater increase the asked amount of significant figures by one. If it is 4 or less make no changes to your number. Finally report the calculated number with the asked amount of significant figures.
What is the significant figures in 14525?
14525 has 5 significant figures (s.f) significant figures help mathematicians to summarise their answer for example to give an approximation if 3 significant figures was required then the answer would be 14500 if you were asked to give 1.1235678 to 4 s.f. then the answer would 1.124 (rounding up the last digit). I hopes this help
Why does there have to be two numbers after the decimal?
There doesn't always have to be two numbers after the decimal. If you are asked to round to the nearest hundreth, then use two places after the decimal. If you are asked to round to the nearest thousandth, then use 3 places after the decimal. If you are asked to round to the nearest tenth, then use 1 place after the decimal. If you are not told where to round, then it is up to you. One common way of doing it is to use significant figures. In other words, if you are dividing two numbers to get a decimal; count the number of significant figures in the divisor and the dividend. Whichever one has the least number of significant figures, use that number of significant figures in your answer. For example: 30.5 / 1.3456789 30.5 has the least number of significant figures; so use 3 significant figures in your answer. Answer: 22.7 If you are working with money, then always use two numbers after the decimal. For example: Add $30.15 + $201.25 Answer: $231.40

How many significant figures in 8000?
Integers ending in 0 are an ambiguous case. I would say 2 significant figures, but if it appeared alongside a list of numbers such as 1710, 1690, 1750, then I would have to say 3 sig figs and if it was with 1705, 1696, 1729 then 4 sig figs.
How many significant figures are in 100?
If you are looking at this from a maths perspective, the 'significant figures' are the number of digits counting from the first non-zero digit, so the number of significant figures in 10.0 is three. You may be asked a question, and told to give the answer 'to three significant figures'. This would mean the answer would look something like '12.2' or '0.0254'. This is in contrast to decimal places, which refer to the number of digits after the decimal point. For example, the number 10.0 is quoted to one decimal place.
How do you find the area of the figure of a rectangle?
Suppose you are asked to find the area of a rectangle that is 2.1- wide by 5.6- long. Your calculator answer would be 11.76 . Now suppose you are asked to enter the answer to two significant figures.
When the atomic mass is 79.904 do you round it to 80?
Numbers should only ever be rounded when a number of significant figures are expressly requested. In this case you would simply leave it as 79.904. However, if you were asked to round 79.904 to two significant figures then the correct answer would be 80 to 2 s.f. Note that you must explicitly specify the significance of the trailing zero otherwise it implies an unwanted level of precision.
