Work: Calculate the value of equation 40*0.13+60*0.28+80*0.34+100*0.1+120*0.086+140*0.064 .
Question type: Mathematical calculation
Solution:
40*0.13+60*0.28+80*0.34+100*0.1+120*0.086+140*0.064
=5.2+60*0.28+80*0.34+100*0.1+120*0.086+140*0.064
=5.2+16.8+80*0.34+100*0.1+120*0.086+140*0.064
=5.2+16.8+27.2+100*0.1+120*0.086+140*0.064
=5.2+16.8+27.2+10+120*0.086+140*0.064
=5.2+16.8+27.2+10+10.32+140*0.064
=5.2+16.8+27.2+10+10.32+8.96
=22+27.2+10+10.32+8.96
=49.2+10+10.32+8.96
=59.2+10.32+8.96
=69.52+8.96
=78.48
Answer:40*0.13+60*0.28+80*0.34+100*0.1+120*0.086+140*0.064=78.48
