The statement "y varies directly as x," means that when x increases, y increases by the same factor. In other words, y and x always have the same ratio: y/x =K
it can be written as ---> y=kx
then put in the values to get a common ratio
k= y/x
k1= 11/7
k2= 13/8
therefore, there's no common ratio in the given table
I believe its 838 inches squared
Density is calculated by mass divided by volume.
This would be 60/24 (60 grams mass divided by 24 cm^3 volume)
60/24 = 2.5
This means the answer is B. 2.5 g/cm^3
