Ответ:
If its density is 2.75 g/cc and
density = mass / volume then its volume is
volume = mass / density
volume = 3,540 g / 2.75 g / cc
volume = 1287.272727 cc
So, rounded it is 1,287.3 cubic centimeters but to keep the same number of significant figures, the volume is
volume = 1,287 cc
Ответ:
So using the theory “allied angles add up to 180 degrees” we can find x
76 + x =180
x= 180-76
x=104 (Option B)
