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

gayaneshka [121]

Answer:

The amount of saturated fat must be listed on food labels, due to the consequences they have for the health of the individual.

Explanation:

Saturated fats are those that have only simple links in their structure, are present in animal-derived foods and are considered harmful to health, by increasing the risk of cardiovascular and cerebrovascular diseases.

Food labels should indicate the <u>nutritional analysis</u>, specifying what nutrients they have and the percentage of the daily requirements they provide, but they should also indicate the content of components that, such as saturated and "trans" fats, may be unhealthy.
