All the possible digits (10 of them; 0-9) are multiplied by themselves by the number of digits that can be shown in the lock. (3) This is 103, or 1,000. This certainly shows why guessing is not a good way to break into a numerical lock, especially since three is a rather low number of digits for one!
1.6 x 2.4= 3.84, now we must realize 1.6cm and 2.4cm are rounded to the tenths digit (.1) so the answer must also be rounded to the tenths didgit, therefore 3.84=3.8. Now we can conclude the product has 2 significant digits due to the fact it has a 3 and 8 as a product and no zeros to make this anymore complicated.
100000 The number 32 in binary is the six-digit number 100000. A binary number uses exponents of 2 rather than 10, and the six digits shown represent 32, 16, 8, 4, 2, and 1 100000 = 32 + 0+ 0 + 0 + 0 + 0 = 32
Two of them.
significant digits. for short they are called "sig. figs."
Significant
4.0 has two significant figure. Significant figures are worked out by finding the first number (working left to right) that is not zero. after finding this number count the number of figures that are shown including zero's
Three. All non-zero digits are significant, all zeroes between other digits, and all digits to the right of the decimal. The reason for this is that if this is rounded off, it apparently is rounded off to the nearest tenth, otherwise the tenth place would not be shown. if it were rounded off to the unit, it would read 39, not 39.0 ■

Answer:0.00900 has 3 significant figures, "9", "0", and "0". The significant figures are shown in bold. This is true because:-All non-zero digits are significant (the nine)-All zeroes trailing the first non-zero digits are NOT significant (the first three zeroes)-If a number has a decimal point, all zeroes AFTER the last non-zero digit are significant (the last two zeroes). Therefore, it has 3 significant digits.

It means round the number so that fewer digits after the decimal point are shown.
500.00(0.05) = 25, to the justified number of significant digits.
Because it may have a deciml in it
