You can take 0.48 as a number, multiply by 100 to that and you get 48%
i have no idea what question you need answered
Its 108 because the triangle is acute so all angle are less than or equal to 90 and i did 54+54+72=180 ant the measurement of the exterior angle is 108

By the divergence theorem, the surface integral taken over

,

is equivalent to the triple integral of the divergence of

over

, the space bounded

,

We have

The latter integral is then given by
2000 grams = 2 kilograms since the prefix kilo- means thousand
