Work: Calculate the value of equation (684.9×10^3)/(0.989×20407.8×215)+(0.89×15.5×10^6)/(1.15×4102761.36×(1-(0.8×684.9)/209442.8)×215) .
Question type: Mathematical calculation
Solution:
(684.9×10^3)/(0.989×20407.8×215)+(0.89×15.5×10^6)/(1.15×4102761.36×(1-(0.8×684.9)/209442.8)×215)
=684900/(0.989×20407.8×215)+(0.89×15.5×10^6)/(1.15×4102761.36×(1-(0.8×684.9)/209442.8)×215)
=684900/4339412.553+(0.89×15.5×10^6)/(1.15×4102761.36×(1-(0.8×684.9)/209442.8)×215)
=684900/4339412.553+13795000/(1.15×4102761.36×(1-(0.8×684.9)/209442.8)×215)
=684900/4339412.553+13795000/(1.15×4102761.36×(1-547.92/209442.8)×215)
=684900/4339412.553+13795000/(1.15×4102761.36×0.997384×215)
=684900/4339412.553+13795000/1011754055.595875
=0.157832+13795000/1011754055.595875
=0.157832+0.013635
=0.171467
Answer:(684.9×10^3)/(0.989×20407.8×215)+(0.89×15.5×10^6)/(1.15×4102761.36×(1-(0.8×684.9)/209442.8)×215)=0.171467
