10 / (1/3); she has 30 pounds of seeds in her supply.
Since 
(density = mass/volume), we can get the mass/weight of the liquid by integrating the density 
over the interior of the tank. This is done with the integral
which is more readily computed in cylindrical coordinates as
4x-35=9x
-4x
-35=5x
divide by 5
x= -7
Answer:
none of the above? sorry not too sure
