Answer:
a
. eight tenths of her cookies
Explanation:
Let the total number of Lakesha's cookies be represented by x.
So that;
She gave three tenths to Bailey =
of x
= ![\frac{3x}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B10%7D)
She gave five tenths to Helen =
of x
= ![\frac{5x}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B10%7D)
Fraction of Lakesha's cookies given away =
+ ![\frac{5x}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B10%7D)
= ![\frac{3x+ 5x}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%2B%205x%7D%7B10%7D)
= ![\frac{8x}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B8x%7D%7B10%7D)
Thus, the fraction of cookies given away by Lakesha is
.
They are both on the same part of the acid line
Space -filling models are also known as Calotte models. These are 3 dimensional models that depict the spatial relationships between atoms.
The space-filling model of water molecule shows the 3 D structure of the water molecule. This model CLEARLY REVEALS THE OXYGEN ATOM WHICH IS LOCATED CENTRALLY WITH TWO HYDROGEN ATOMS IN THE ADJACENT SIDES. THE MODEL ALSO SUGGESTS HOW THE WATER MOLECULES ATTRACT EACH OTHER.
<span>This type of reaction is called a synthesis reaction. This type of reaction occurs when two or more components combine to form a single compound. During this formation, heat and energy is released, ergo it is an exothermic type of reaction.</span>
