need help with these questions please
1. Why 5.67 +0.00032 = 5.67 (and not 5.7 or 5.67032 or any other number). 2. Why does 4.03/0.0000035 1.2 x 106, instead of a different number of significant figures? 3. Why is it that 85.48 rounded to two sig. figs. is 85 and not 86?
Determine the answer to the following equation with correct number of significant figures: (4.123x0.12) + 1.2 x 0.55 = none of these 1.16 1.15 1.2 0 1.155
Which of the answers for the following conversions contains the correct number of significant figures? A)2.543 m x 39.4in/1m=100.1924in B)2 L x 1.06qt/1L=2.12 qt C)24.95 min x 1hr/60 min=0.4158 hr D)12.0 ft x 12in/1ft x 2.54cm/1in=370cm E)24.0 kg x 1lb/2.20kg=11lbthe answer is c but i dont understand why. i thought you round the answer based on the number of sig figs of the lowest measurement so why wouldn't D be the answer?
Correct sig figs please
