Work: Calculate the value of equation 155×(0.86+0.78+0.7+0.62)+1/2×52.7×11.6×0.58+1/2×52.7×0.1×2 .
Question type: Mathematical calculation
Solution:
155×(0.86+0.78+0.7+0.62)+1/2×52.7×11.6×0.58+1/2×52.7×0.1×2
=155×2.96+1/2×52.7×11.6×0.58+1/2×52.7×0.1×2
=458.8+1/2×52.7×11.6×0.58+1/2×52.7×0.1×2
=458.8+0.5×52.7×11.6×0.58+1/2×52.7×0.1×2
=458.8+26.35×11.6×0.58+1/2×52.7×0.1×2
=458.8+305.66×0.58+1/2×52.7×0.1×2
=458.8+177.2828+1/2×52.7×0.1×2
=458.8+177.2828+0.5×52.7×0.1×2
=458.8+177.2828+26.35×0.1×2
=458.8+177.2828+2.635×2
=458.8+177.2828+5.27
=636.0828+5.27
=641.3528
Answer:155×(0.86+0.78+0.7+0.62)+1/2×52.7×11.6×0.58+1/2×52.7×0.1×2=641.3528
