Dr. drazzle colloect 70 l of ocean water to test for antibacterial properties he splits the water into 100 samples how much water is in each sample ?

0.7 l or 700 ml

Step-by-step explanation:

70 l /100= 70/100 l = 7/10 l = 0.7 l = 0.7 x 1000ml = 700ml

Ans: Each sample had 0.7 l/ 700 ml of water.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
