9.0 has two significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
1,000 divided by 90 equals 11 with a remainder of 10.
Since 90 is a whole number, rounding 85 to 90 does result in a whole number.
Absolute value of -90 is 90.
Simple, divide 900 by 10!
(80 + 90) / 2 = 85Therefore, the number between 80 and 90 is 85.
The digit 90 has only one applicable significant figure.
It could be one or two.
One mile is equal to 160934.4 centimetres. Therefore, rounded to three significant figures, 90 centimetres is equal to 90/160934.4 = 0.000559 miles.
The rule for significant figures is that all non-zero digits are considered significant. Zeros between non-zero digits are significant, as well as trailing zeros after a decimal point. Leading zeros (zeros to the left of the first non-zero digit) are not considered significant.
It is 90, exactly as in the question.A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Adding zeros after the decimal point is wrong because they imply a degree of accuracy (significant figures) for which there is no justification.
(76/100)90 = 68, to the justified number of significant digits from the problem statement; if the integers in the problem statement are considered exact, then the answer is 68.4
618/7 = 88.28571429% or 88% correct to 2 significant figures.
90 pounds x 1 kg/2.205 pounds = 40.82 kg = 40 kg (to one significant figure)
