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.

Drag each tile to the correct location. Determine whether each sentence describes oceanic crust, continental crust, or both. It

neonofarm [45]

Given what we know, the three sentences in this question all describe the properties of oceanic crust.

<h3>What is the oceanic crust?</h3>

The oceanic crust is the outer layer of the earth, located at the bottom of the oceans.
It contains three layers, ordered by number.
During subduction, this remains the topmost crust.
It is formed by the solidification of magma.
The oceanic crust is known to be very dense.

Therefore, we can confirm that the sentences in the question describe oceanic crust given that this is the topmost crust during subduction, formed by the solidifying of magma, making it a much denser rock than the other forms of crust.

Explain how the structure of the cells that you have studied give evidence if a creator

laila [671]

Hi!

So, assuming that you mean a creator as in a religious deity - we're going to run into problems here.

In order for something to be scientifically validated, it has to be proven scientifically by following the scientific method.

As science is based off the physical world, the things we prove must reflect that. The idea of a deity is something which lies outside the physical realm.

This means that any proof that we do find a 'creator', will simply just be something we now know about the physical world.

We can't have scientific evidence of something which we cannot prove scientifically. 

With that said, unless there is context or a piece of information missing, the question is unanswerable.

Hopefully, this helps! =)
