Work: Calculate the value of equation (500×20×(117.7-10))+(2×10×(440-342.3)×(440-342.3)/2)-(2×10×342.3×342.3/2) .
Question type: Mathematical calculation
Solution:
(500×20×(117.7-10))+(2×10×(440-342.3)×(440-342.3)/2)-(2×10×342.3×342.3/2)
=(500×20×107.7)+(2×10×(440-342.3)×(440-342.3)/2)-(2×10×342.3×342.3/2)
=1077000+(2×10×(440-342.3)×(440-342.3)/2)-(2×10×342.3×342.3/2)
=1077000+(2×10×97.7×(440-342.3)/2)-(2×10×342.3×342.3/2)
=1077000+(2×10×97.7×97.7/2)-(2×10×342.3×342.3/2)
=1077000+95452.9-(2×10×342.3×342.3/2)
=1077000+95452.9-1171692.9
=1172452.9-1171692.9
=760
Answer:(500×20×(117.7-10))+(2×10×(440-342.3)×(440-342.3)/2)-(2×10×342.3×342.3/2)=760
