What is 3.000 divided by 1?
3
How many 2-digit numbers can be formed using the digits 1 3 7 if repetition of digits is allowed?
Possible solutions - using your rules are:- 11,13,17,31,33,37,71,73 &77
Why is it smart to use rounding on front end estimation after finding an answer?
By using front end estimation, the numbers that you start of with have only one significant digit. It is, therefore, nonsense to have an answer with loads of significant digits.
What is the result of multiplying the measurements 5.81 ft x 81 ft x 74.41 ft using the correct significant digits for the answer?
The answer is 35000 cubic feet.
What are the the 3 digit numbers using 1345678?
Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.
What is the following expression 77.94 - 5.8 plus 201.681 simplified using the rules of significant figures?
Do the calculations, then round to one decimal digit, since the least precise of the numbers involved has one decimal digit.

What do significant figures tell about an instrument?
They tell you what level of precision you can expect from measurements that are made using that instrument.
What is 56.02 take away 4.6 plus 100.648 using the rules of significant figures?
Answer: 152.1
Who invented significant figures?
William Thomson, also known as Lord Kelvin, is credited with introducing the concept of significant figures in the late 19th century. He recognized the importance of indicating the precision of measurements by using digits that were known with certainty along with one uncertain digit.

Why are significant figures important when taking data in the laboritory?
Significant figures help communicate the precision of a measurement. They indicate the level of certainty in the measured value and help prevent misleading conclusions. Using the correct number of significant figures ensures accuracy and consistency in scientific data analysis.

How is precision related to the significant figures in a measured quantity?
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
How do you round 9174.48 to have the same amount of significant digits as 79.0?
79.0 has three significant figures - as trailing zeros after a decimal point are not usually written, to have been written the zero must have significance. Thus 9174.48 needs to be rounded to 3 significant figures, which is done by using the 4th digit to round the 3rd: the 4th digit is 4, so the number rounds down to 9170
