Work: Calculate the value of equation 850×30×(251.8-15)+3×30×(251.8-30)×(251.8-30)/2 .
Question type: Mathematical calculation
Solution:
850×30×(251.8-15)+3×30×(251.8-30)×(251.8-30)/2
=850×30×236.8+3×30×(251.8-30)×(251.8-30)/2
=850×30×236.8+3×30×221.8×(251.8-30)/2
=850×30×236.8+3×30×221.8×221.8/2
=25500×236.8+3×30×221.8×221.8/2
=6038400+3×30×221.8×221.8/2
=6038400+90×221.8×221.8/2
=6038400+19962×221.8/2
=6038400+4427571.6/2
=6038400+2213785.8
=8252185.8
Answer:850×30×(251.8-15)+3×30×(251.8-30)×(251.8-30)/2=8252185.8
