17. If the area of a square is 64 square centimeters, what's the length
of one side?
O A. 4 cm
OB. 8 cm
O C.32 cm
O D. 16 cm

B = 8cm

Step-by-step explanation:

We know the area of a square is given by

A = s^2  where s is the side length

64 = s^2

Take the square root of each side

sqrt(64) = sqrt(s^2)

8 =s

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

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
