Significant Figures in calculations having a mixture of functions ( /- and x/÷) Solve the following calculations mathematically and report your final answer with the correct significant figures. Remember, the math is not hard but the significant figures are complicated. Follow the rule that applies to the function you are performing. Do not round intermediate values but follow information about significant figures after each function and round your final answer to the appropriate significant figures.1.2.3. 126.96.36.199.8.0.0521 112.40 3.02391 24.0224 31.9988 3.00000 × ( ( )× 00)5.6629 47.90 2.0000000 1.00797 15.9994 × ( × ( ))( )28.641−2.3154 2.1 ( )( )0.4680 135.79 16.0128.42 129.226− ×−(0.8000 0.7943)0.8000−( ) ( ) 20.00748214 5.6237 10 1161 20 × × ÷(28.621 81.993 100.000 ) ×8640. 85.4861 17.0 317.65 × For the these problems, set up the calculation using dimensional analysis making your work clear and complete (all conversion factors and units shown).
