[1/1 Formula]
Work: Calculate the value of equation 1/2×(16.1×(2.1-0.857)+(30.46+52.94)×1.9+(55.11+75.38)×2.2+(56.67+88.26)×6) .
Question type: Mathematical calculation
Solution:
1/2×(16.1×(2.1-0.857)+(30.46+52.94)×1.9+(55.11+75.38)×2.2+(56.67+88.26)×6)
=1/2×(16.1×1.243+(30.46+52.94)×1.9+(55.11+75.38)×2.2+(56.67+88.26)×6)
=1/2×(16.1×1.243+83.4×1.9+(55.11+75.38)×2.2+(56.67+88.26)×6)
=1/2×(16.1×1.243+83.4×1.9+130.49×2.2+(56.67+88.26)×6)
=1/2×(16.1×1.243+83.4×1.9+130.49×2.2+144.93×6)
=1/2×1335.1303
=0.5×1335.1303
=667.56515
Answer:1/2×(16.1×(2.1-0.857)+(30.46+52.94)×1.9+(55.11+75.38)×2.2+(56.67+88.26)×6)=667.56515
