Work: Calculate the value of equation (421.5×10^3)/(0.978×7916.8×215)+(0.95×6.64×10^6)/(1.15×819724.71×(1-(0.8×421.5)/33756.90)×215) .
Question type: Mathematical calculation
Solution:
(421.5×10^3)/(0.978×7916.8×215)+(0.95×6.64×10^6)/(1.15×819724.71×(1-(0.8×421.5)/33756.90)×215)
=421500/(0.978×7916.8×215)+(0.95×6.64×10^6)/(1.15×819724.71×(1-(0.8×421.5)/33756.90)×215)
=421500/1664665.536+(0.95×6.64×10^6)/(1.15×819724.71×(1-(0.8×421.5)/33756.90)×215)
=421500/1664665.536+6308000/(1.15×819724.71×(1-(0.8×421.5)/33756.90)×215)
=421500/1664665.536+6308000/(1.15×819724.71×(1-337.2/33756.90)×215)
=421500/1664665.536+6308000/(1.15×819724.71×0.990011×215)
=421500/1664665.536+6308000/200652394.648395
=0.253204+6308000/200652394.648395
=0.253204+0.031437
=0.284641
Answer:(421.5×10^3)/(0.978×7916.8×215)+(0.95×6.64×10^6)/(1.15×819724.71×(1-(0.8×421.5)/33756.90)×215)=0.284641
