Work: Calculate the value of equation 0.14+2*1.4*20+2*0.45*10+2*0.2*20+2*0.42*50+0.15 .
Question type: Mathematical calculation
Solution:
0.14+2*1.4*20+2*0.45*10+2*0.2*20+2*0.42*50+0.15
=0.14+2.8*20+2*0.45*10+2*0.2*20+2*0.42*50+0.15
=0.14+56+2*0.45*10+2*0.2*20+2*0.42*50+0.15
=0.14+56+0.9*10+2*0.2*20+2*0.42*50+0.15
=0.14+56+9+2*0.2*20+2*0.42*50+0.15
=0.14+56+9+0.4*20+2*0.42*50+0.15
=0.14+56+9+8+2*0.42*50+0.15
=0.14+56+9+8+0.84*50+0.15
=0.14+56+9+8+42+0.15
=56.14+9+8+42+0.15
=65.14+8+42+0.15
=73.14+42+0.15
=115.14+0.15
=115.29
Answer:0.14+2*1.4*20+2*0.45*10+2*0.2*20+2*0.42*50+0.15=115.29
