Answer:

The purpose of the carbon cycle is to utilize the carbon by the organisms such as plant which uses carbon in the form of carbondioxide for making food. This carbon is stored in the form of glucose. When this food is eaten by the animals, it is broken down into simpler substances and carbondioxode is released in the atmosphere again.

Some carbon is present in soil which is used by microorganisms such as bacteria. So carbon cycle is very important for the survival of life on earth.

ELEN [110]

Answer:

Total 495 liters of natural oil are needed.

Explanation:

It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.

It means the ratio of natural oil and synthetic oil is

$\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{5}{5+3}=\frac{5}{8}$

Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.

It means the ratio of natural oil and synthetic oil is

$\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{x}{792}$

Equate both ratios,

$\frac{x}{792}=\frac{5}{8}$

On cross multiplication we get

$8\times x=5\times 792$

$8x=3960$

Divide both sides by 8.

$x=\frac{3960}{8}$

$x=495$

Therefore total 495 liters of natural oil are needed.
