Answer:

The correct option is B. two oxygen atoms

Step-by-step explanation:

The molecular formula for carbon dioxide is given by :

CO_2

Here, the alphabet C stands for Carbon and the alphabet O stands for Oxygen.

And the prefixes of each of these words represents the number of atoms present of the corresponding element in one molecule of carbon dioxide.

So, The prefix of the first word that is C is 1

⇒ One molecule of carbon dioxide contains one atom of Carbon.

The prefix of the second word that is O is 2

⇒ One molecule of carbon dioxide contains 2 atoms of Oxygen.

Therefore, The correct option is B. two oxygen atoms

In compounds composed of non-metals, prefixes are used to determine the number of atoms existing in the compound. In this case, the prefix of the second word indicates that a molecule of carbon dioxide indicates that the compound contains two oxygen atoms.

Factor out the coefficient of the variable 5/6s+2/3
DochEvi [55]
Okay. so I'm gonna assume you know what factor out means--were gonna take out 5/6. what we need to know is, how does that affect our ending number 2/3? well, we're gonna have 5/6 times some stuff first off, right?

5/6 ( )

so what's in the parenthesis? well, if we distribute in our mind, S would just have to be by itself for it to work out. so we have

5/6 ( s )

but what about 2/3? well, if we're multiplying everything on the inside by 5/6, how can be get it to cancel and leave 2/3 alone? we could divide 2/3 by 5/6, right?

5/6 ( s + (2/3) / (5/6) )

now, when we distribute our 5/6, we'll have just 2/3 at the end. now let's simplify that end term so it looks a little better. if we divide by a fracion, that's the same as multiplying by the flipped version, so let's do that.

2/3 / 5/6 = 2/3 × 6/5 = 2 (6) / 5 (3) = 12/15

we can reduce 12/15 by dividing the top and bottom by three.

= 4/5

so our final answer would be:

5/6 [S + 4/5] you can redistribute to make sure it matches. Anyway, hope that helps!

For each triangle, find the missing side length to the nearest tenth. :
Lana71 [14]
We can use trigonometry.  The cosine of 15 will be the side adjacent to the 15-degree side (the one we are looking for) divided by 20, the hypotenuse.  As cos(15) is about .966, we get 19.32 as the side we are looking for.

Please help
Kisachek [45]

Answer:

1/2

Step-by-step explanation:

A coin has 2 sides, and it is flipped 3 times. 3 x 2 = 6. Each flip only has a head, so 3 flips would have 3 heads.

3/6 = 1/2
