Does anyone know this a. 5.831 mb. 16.552 mc. 2.828 md. 13.267 m

D. 13.267 m

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

7^2 + b^2 = 15^2

49 + b^2 = 225

Subtract 49 from each side

b^2 = 225-49

b^2 =176

Take the square root of each side

sqrt(b^2) = sqrt(176)

b = sqrt(176)

b = 13.266

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

gimmee one of those gold crowns!
