[1/1 Formula]
Work: Calculate the value of equation -1/12×(6.5)^2×156.49-1/20×(6.5)^2×90.59 .
Question type: Mathematical calculation
Solution:
-1/12×(6.5)^2×156.49-1/20×(6.5)^2×90.59
=-1/12×6.5^2×156.49-1/20×(6.5)^2×90.59
=-1/12×6.5^2×156.49-1/20×6.5^2×90.59
=-1/12×42.25×156.49-1/20×6.5^2×90.59
=-1/12×42.25×156.49-1/20×42.25×90.59
=-0.083333×42.25×156.49-1/20×42.25×90.59
=(-3.520819)×156.49-1/20×42.25×90.59
=(-550.972965)-1/20×42.25×90.59
=-550.972965-0.05×42.25×90.59
=-550.972965-2.1125×90.59
=-550.972965-191.371375
=-742.34434
Answer:-1/12×(6.5)^2×156.49-1/20×(6.5)^2×90.59=-742.34434
