When multiplying or dividing measurements the answer has the same number of significant figures as the measurement with the most significant figure?
When multiplying/dividing measurements the answers needs to have the same amound significant figures as the one with the LEAST amount
What are significant figures-?
When a number is written in scientific notation, the digits that do not appear are not significant. The rest are significant figures. For example, when you convert 0.0003102 to scientific notation, it is 3.102 X 10-4. Therefore the zeros before the 3 are not significant.The 3 significant figures implies to all digits around it, regardless of before and after the decimal point. 8.00 has 3 sig.figs. This is because of the 2 zeroes after the decimal point. When you have 30 zeroes after the decimal point, such as 3.000000000000000000000000000000, you have 31 significant figures. 1.23 has 3 sig.figs. This applies to all questions, if needed.The amount of figures given in an answer where you begin with approximates of numbers. The answers should not be more precise than the original measurements. This would lead to a misleading answer, and thus significant figures were created to show an accurate approximation of your answer.The idea of significant figures (sig figs or sf), also called significant digits (sig digs) is a method of expressing error in measurement.The most significant digit is the "first" digit of a number (the left-most non-zero digit). Similarly, the least significant digit is the "last" digit of a number (sometimes, but not always, the right-most digit). A number is called more significant because it carries more weight. In the decimal number system (base 10), the weight of each digit to the left increases by a multiple of 10, and conversely the weight of each digit to the right decreases by a multiple of 10. A similar thing happens in the binary (base 2) number system - see most significant bit.Sometimes the term "significant figures" is used to describe some rules-of-thumb, known as significance arithmetic, which attempt to indicate the propagation of errors in a scientific experiment or in statistics when perfect accuracy is not attainable or not required. Scientific notation is often used when expressing the significant figures in a number.The concept of significant figures originated from measuring a value and then estimating one degree below the limit of the reading; for example, if an object, measured with a ruler marked in millimeters, is known to be between six and seven millimeters and can be seen to be approximately 2/3 of the way between them, an acceptable measurement for it could be 6.6 mm or 6.7 mm, but not 6.666666... mm as a recurring decimal. This rule is based upon the principle of not implying more precision than can be justified when measurements are taken in this manner. Teachers of engineering courses have been known to deduct points when scoring papers if excessive significant figures are given in a final answer.Each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit.Significant figures (also called significant digits) can also refer to a crude form of error representation based around significant figure rounding.Significant figures are digits that show the number of units in a measurement expressed in decimal notation.
What are the answers to the mymaths significant figures questions?
I'm sorry by the questions on mymaths are different for each person, therefore no one can tell you the answers unless they have the original questions.
What is the difference between customary measurements and the metric measurements?
Metric measurements use powers of 10. Any other system has NO bases or logic.
Are the answers to circumference questions squared or cubed?
Neither because the circumference of a circle is a measurement of length
When multiplying or dividing measurements the answer has the same number of significant figures as the measurement with the most significant figure?
When multiplying/dividing measurements the answers needs to have the same amound significant figures as the one with the LEAST amount
Which of these answers has exactly three significant figures?
98.6
How many significant figures should be reported in the answer -2.006?
Three, so the answer would be 3.96. Always use the number with the smallest amount of significant figures to determine the amount of significant figures will be in the solution.

How many significant figures are in 400ml?
The question is ambiguous. The possible answers are 1, 2 or 3.
How many significant digits are in 74.30?
You cannot round off a number to 3 significant figures when it already has more than 3 significant figures. The number 10074 has 5 significant figures (1, 0, 0, 7 and 4). If the number were really 1.0074, then it could be rounded off to 3 significant figures: 1.01.
What is only numbers with four significant figures?
There are infinitely ma,y possible answers. For example 0.0002389 or 1654000000.
How do you round off 397837.156?
We need to know to how may significant figures to answer you precisely, 397837.16 and 400000 are both valid answers.

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 can a measurement be accurate but not precise?
Precision: how close measurements are to each other Accuracy: how close measurements are to the "true" or accepted value. If you do 3 trials of an experiment and you get 1.00 grams, 1.01 grams, and 1.03 grams as your answers but the real value was supposed to be close to 6.79 grams, your data was precise but not accurate.
