Answer:
The mixtures are not proportional.
3 fluid ounces of vinegar has to be added in the second mixture to make it proportional to the first mixture.
its =3
Step-by-step explanation:
The one mixture contains 6 fluid ounces and 10 fluid ounces of water and vinegar respectively.
Therefore, the ratio of water to vinegar in the first mixture is 6 : 10 = 3 : 5
Now, a second mixture contains 9 fluid ounces of water and 12 fluid ounces of vinegar.
Hence, the ratio of water to vinegar in the second mixture is 9 : 12 = 3 : 4
Therefore, the mixtures are not proportional.
Therefore, we have to add x fluid ounces of vinegar to the second mixture to make it in the ratio of 3 : 5.
So,
⇒ 12 + x = 15
⇒ x = 3 fluid ounces.
Therefore, 3 fluid ounces of vinegar has to be added in the second mixture to make it proportional to the first mixture. (Answer

Answer: Average discharge at the mouth of the Amazon River in 1 hour = cubic feet
Average discharge at the mouth of the Amazon River in 1 year= cubic feet[/tex]
Step-by-step explanation:
Given : The average discharge at the mouth of the Amazon River =4,900,000 cubic feet per second.
i.e. The average discharge at the mouth of the Amazon River in 1 second= 4,900,000 cubic feet
Since 1 hour = 3600 seconds
Then , the average discharge at the mouth of the Amazon River in 1 hour =
cubic feet
Since , there are 2080 hours in a typical year.
Then, the average discharge at the mouth of the Amazon River in 1 year=
cubic feet
