So i'm having a bit of trouble with the same thing again, sorry for asking this many questions for the same lesson but my moms bf who passed and was top in his calculus classes didn't even understand it! shocker huh? anyways here's the question;



I disagree with this hypothesis, because, the rows only support how many valence electrons there are, but do not support the chemical reaction. However, the columns do. Each column on the periodic table is one group. These groups share similar chemical properties, and react similarly in reaction. In conclusion, the hypothesis is incorrect.
Hope this helped.
Hey buddy please specify the trouble so that we can answer that
AD = 42-x

The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides  ⇒
36/27 = (42-x)/x
36x = 27(42-x)
36x = 1134 - 27x
36x + 27x = 1134
63x = 1134
x = 1134/63
x = 18


The liver has many function in addition to detoxification, including manufacturing enzymes, storage of glycogen and vitamins. and metabolism of fats, proteins, and carbohydrates;


Lipid metabolism begins in the smooth ER especially in the hepatocyte cells of the liver that have a lot of this organelle.

In the smooth ER, the fatty acids chains are converted to acyl-CoA by acyl-CoA synthetase. The acyl-CoA then enters the mitochondria and converted to Acetyl-CoA of the Critic cycle through beta-oxidation

Additionally, the glycerol of the triglycerides is converted to glyceraldehyde 3-phosphate that is an intermediate of the glycolysis metabolic cycle.

The lipids are also assembled in the smooth ER whereby they are used to create lipoproteins so the hydrophobic lipids can be transported through blood to other tissues

Excess carbohydrates and proteins are also stripped to their skeleton and this is used to convert them to fatty acids

I believe it is 27.

Step-by-step explanation:

Add the 3 to the 8 to get 11. Then add 7 to 9 to get 16. Add 11 to 16 to get 27.

When we move across a period then there occurs an increase in the number of electrons of atoms from left to right. These electrons are added to the same sub-shell.

For example, elements present in row 2 will have electrons present in n = 2 which is the highest energy level for row 2 elements.

Hence, there are different number of valence electrons present in the elements of a row.

Whereas when we move down a group then elements have same number of valence electrons. As a result, they tend to show similar chemical properties.

But since, there are no same number of valence electrons in the elements of a row. Hence, they do not show similar chemical properties. Therefore, elements of a row do not behave same in chemical reactions.

Thus, we can conclude that we disagree with the hypothesis given by the student.  


To find this get k by itself and to do so get rid of the numbers on it's side.

To do so do the opposite of the symbol

Ex: when adding, subtract it from both sides.

Ex when dividing multiply both sides

Now to solve this

Divide 2 from both sides which gives the answer


  29 by 70 meters

Step-by-step explanation:

You need to know how area and perimeter relate to the dimensions of the lawn.

The area formula is ...

  A = LW . . . . . . . the product of length and width

The perimeter formula is ...

  P = 2(L+W) . . . . twice the sum of length and width

The latter tells you the sum of length and width will be ...

  P/2 = L + W = (198 m)/2 = 99 m


It usually works well to assume that the dimensions are integers, then look for the factors of the area figure that give the right perimeter.

  2030 = 2·5·7·29

  = 2×1015 = 5×406 = 7×290 = 10×203 = 14×145 = 29×70 = 35×58

Of these factor pairs, the one that has a sum of 99 is (29, 70).

The dimensions of the lawn are 29 m by 70 m.


You can also solve this graphically or algebraically. The graphical solution finds the points of intersection between LW=2030 and L+W=99, or the equivalent. Attached is a graph of the problem.

The algebraic solution can use substitution:

  L = 99-W

  2030 = (99 -W)(W)

  W² -99W +2030 = 0 . . . . subtract the right side and put in standard form

  W = (99±√(99² -4·2030))/2 . . . . . . use the quadratic formula

  W = (99 +√1681)/2 = (99 ±41)/2 = {29, 70}

It doesn't matter which dimension you call the width.

The lawn is 29 m by 70 m.


The quadratic formula tells you the solution to ...


is given by ...


Here, we have a=1, b=-99, c=2030.

Of course (-99)² = 99², and 4(1)(2030) = 4·2030, so we have simplified the solution a little bit when writing it above.

This is my third time asking this and no answer, i need to get this done today. i will give brainlie
I'm not sure I understand the question. But if I do understand it, it should be x=1/3 

Do you know the answer?
