Answer:
Step-by-step explanation:
Given data:
Mass of the liquid ( m ) = 550 kg
Volume of the liquid ( v ) = 680 litre
= 680*10-3 m3
= 0.68 m3
Now, Density of the liquid = (m/v)
= (550 kg )/(0.68 m3)
= 809 kg/m3
0.6 or 18/30 because 9 divided by 15 is .6
I have checked and the answer is x=7
It will take an additional 8 weeks to reach a height of 48 centimeters.
y = 4.5x
Since, the maximum height is 48 cm and the plant has already grown 12 cm, we deduct the 12 from 48 to get the additional weeks it needs to grow.
48 - 12 = 4.5x
36 = 4.5x
36/4.5 = 4.5x / 4.5
x = 8 weeks.
