Work: Calculate the value of equation (31+(20.10-19.12)×18.6+(19.12-16.32)×19.5+(16.32-11.20)×20)×0.70 .
Question type: Mathematical calculation
Solution:
(31+(20.10-19.12)×18.6+(19.12-16.32)×19.5+(16.32-11.20)×20)×0.70
=(31+0.98×18.6+(19.12-16.32)×19.5+(16.32-11.20)×20)×0.70
=(31+0.98×18.6+2.8×19.5+(16.32-11.20)×20)×0.70
=(31+0.98×18.6+2.8×19.5+5.12×20)×0.70
=206.228×0.70
=144.3596
Answer:(31+(20.10-19.12)×18.6+(19.12-16.32)×19.5+(16.32-11.20)×20)×0.70=144.3596
