Two of them.
500.00(0.05) = 25, to the justified number of significant digits.
It means round the number so that fewer digits after the decimal point are shown.
This is the decimal value 15. A binary number uses exponents of 2 rather than 10, and the 8 digits shown represent 128, 64, 32, 16, 8, 4, 2, and 1 00001111 (or just 1111) = 0+0+0+0+8+4+2+1 = 15 Add the values of each exponential where there is a 1 value.
0.12 = 3/25
the GCF is 10
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.
Six of them.
significant digits. for short they are called "sig. figs."
Significant
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.
Consider it a convention. Basically, it doesn't make much sense to register many more digits after a digit that is uncertain. Another common convention is to enclose uncertain digits - often the last two digits shown - in parentheses, for example, 6.67384(80)×10−11 for the gravitational constant in SI units.,
an arrangement of data for 2-digit numbers , the tens digits are shown as the "steams" and the ones digits as the "leaves" Example: 19,22,25,26,27,28,29,30,34,36,37,42,43,44,46,48,48,49,52,53,55,57,58,62
There is an error in the question. the last group of digits in the question is wrong. it should read 312211.this means the answer shown is wrong. The correct answer is 13211221.
binary.
You cannot have a product of only one number!
