[1/1 Formula]
Work: Calculate the value of equation -1/12×(6.5)^2×65.9-1/20×(6.5)^2×90.59 .
Question type: Mathematical calculation
Solution:
-1/12×(6.5)^2×65.9-1/20×(6.5)^2×90.59
=-1/12×6.5^2×65.9-1/20×(6.5)^2×90.59
=-1/12×6.5^2×65.9-1/20×6.5^2×90.59
=-1/12×42.25×65.9-1/20×6.5^2×90.59
=-1/12×42.25×65.9-1/20×42.25×90.59
=-0.083333×42.25×65.9-1/20×42.25×90.59
=(-3.520819)×65.9-1/20×42.25×90.59
=(-232.021972)-1/20×42.25×90.59
=-232.021972-0.05×42.25×90.59
=-232.021972-2.1125×90.59
=-232.021972-191.371375
=-423.393347
Answer:-1/12×(6.5)^2×65.9-1/20×(6.5)^2×90.59=-423.393347
