I believe you mean how many feet are in 101cm.1 foot = 30.48cm1cm = 0.032808399 feetTherefore: 101cm = 0.032808399*101 = 3.3136483 feet3.3 feet to 2 significant figures
Three in 150.With trailing zeros it can be ambiguous.One thing is certain: if you use scientific notation there is nor doubt.In scientific notation one hundred fifty can be written as1.5 * 102 in which case there are two significant figuresor it can be written as1.50 * 102 (or 15.0*101) with three significant figures [However there also is one trailing zerohere!]or as1.500 * 102 (four significant figures) this also could be expressed as 150.0 - no doubt there that there are four significant figures for zeros to the right of the decimal point!

5.7*101 or 5.7 E1
Just 1 and 101. 101 is prime.

Assuming 5 is not an exact value, the 5 has one significant figure and the 5.364 has four significant figures. 5.364 x 5 = 26.82 However, since 5 only has one significant figure, you would round the 26.82 to be 30 or 3 x 101 30 has one significant figure.

If you are rounding off to two significant figures the result is 33.Sixes always round up to the next higher digit i.e.296 to two significant figures is 30 *101
Three
5.7*101 or 5.7 E1
5 of them.
Four. All non zero numbers are always significant. Zeroes that are between non zero numbers are always significant. Zeroes that are to the right of a non zero number and that contain a decimal point are significant.
70 in scientific notation is 7 x 101 (might show up as 7E1 on some calculators). Watch out for significant figures and avoid 7.0 x 101 as the zero is not a sig fig in this case since there is no decimal.
It depends to how many significant figures: 1 sig fig => 10 (technically 1 x 101 or 1e1) 2 sig fig => 13 3 sig fig => 12.7 4 sig fig => 12.74 5 sig fig => 12.744
