解:
50*0.75*10*0.9174+50*0.75*11*0.8417+50*0.75*12.1*0.7722
=37.5*10*0.9174+50*0.75*11*0.8417+50*0.75*12.1*0.7722
=375*0.9174+50*0.75*11*0.8417+50*0.75*12.1*0.7722
=344.025+50*0.75*11*0.8417+50*0.75*12.1*0.7722
=344.025+37.5*11*0.8417+50*0.75*12.1*0.7722
=344.025+412.5*0.8417+50*0.75*12.1*0.7722
=344.025+347.20125+50*0.75*12.1*0.7722
=344.025+347.20125+37.5*12.1*0.7722
=344.025+347.20125+453.75*0.7722
=344.025+347.20125+350.38575
=691.22625+350.38575
=1041.612 答案:50*0.75*10*0.9174+50*0.75*11*0.8417+50*0.75*12.1*0.7722=1041.612你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
