Cell A has a surface area of 50 μm^2 and a volume of 10 μm^3. Cell B has a surface area of 14 μm^2 and a volume of 7μm^3. Using the information above, determine the surface-area-to-volume ratio of each cell. What is the SA:V ratio of the cell that will exchange materials with its environment at the fastest rate of diffusion?

could you reply to this with the question so i can ?

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
