Make each denominator rational. In other words, rationalize the denominator.
[tex] \frac{3 + \sqrt{6} }{ \sqrt{6} } = ... \\ = \frac{3 + \sqrt{6} }{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } = \frac{3 + ( \sqrt{6} \sqrt{6} ) }{6} \\ = \frac{3 + ( \sqrt{6} {}^{2}) }{6} = \frac{3 + 6}{6} \\ = \frac{9}{6} = \bold{1\frac{1}{2}} [/tex]
Answer:
[tex]\frac{\sqrt6 + 2}{2}[/tex]
Step-by-step explanation:
Hello!
To rationalize the denominator, we want the denominator to be rid of any square root operations.
To do that we have to multiply the whole fraction by the value of the denominator, or multiply it by a Giant 1.
Rationalize:
[tex]\frac{3 + \sqrt6}{\sqrt6}[/tex][tex]\frac{3 + \sqrt 6}{\sqrt6} * \frac{\sqrt6}{\sqrt6}[/tex][tex]\frac{\sqrt6(3 + \sqrt6)}{\sqrt6 * \sqrt 6}[/tex][tex]\frac{3\sqrt6 + 6}{6}[/tex]Simplify:
[tex]\frac{3(\sqrt6 + 2)}{3(2)}[/tex][tex]\frac{\sqrt6 + 2}{2}[/tex]Final expression: [tex]\frac{\sqrt6 + 2}{2}[/tex]

Giant 1A giant one is another term for a fraction that simplifies to 1. To simplify to
one, the fraction's numerator and denominator have to be the same. We
multiplied our expression by √6/√6, which doesn't change the value of the
original expression because we are technically multiplying by 1.

12.12 x (−2.9)
Answer:
-35.148
I don't know if you need to round the answer or not
Step-by-step explanation:
Hello there!
Question:-[tex]\sf \longmapsto 1.12 \: \times ( - 2.9)[/tex]
This is a arithmetic expression.We need to find the result of it.
Solution:-[tex]\sf \longmapsto12.12 \times ( - 2.9)[/tex]
As (-) * (+) equals to (+),
The new Arithmetic expression will be :-
[tex]\sf \longmapsto - (12.12 \: \times 2 . 9)[/tex]
Then, Simply multiply :-
[tex]\sf \longmapsto - (35 .148)[/tex]
Remove the parenthesis:-
[tex]\sf \longmapsto - 35.148[/tex]
On Converting -35.148 to fraction :-
[tex]\sf \longmapsto \: - \dfrac{8787}{250} [/tex]
On Mixed fraction:-
[tex]\sf \longmapsto \: - 35\dfrac{37}{250} [/tex]
______________________________________
Henceforth the answer of the arithmetic expression is :-
[tex] \boxed{\bf \: - 35.148 \: (approx.)}[/tex]
In Alternate Form:-
[tex]\boxed{\bigg\{\bf \: - \dfrac{8787}{250} , - 35\dfrac{37}{250}\bigg\}} [/tex]

The figure below shows a quadrilateral ABCD. Sides AB and DC are congruent and parallel:
A quadrilateral ABCD is shown with the opposite sides AB and DC shown parallel and equal.
A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram:
Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent. Side AB is equal to side DC, and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by SSS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel.
Which statement best describes a flaw in the student's proof?
Question 11 options:
Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.
Triangles ABD and CDB are congruent by the SAS postulate instead of the SSS postulate.
Triangles ABD and BCD are congruent by the AAS postulate instead of the SSS postulate.
Angle DBC and angle BDA form a pair of corresponding angles, not a pair of alternate interior angles, which are congruent.
Answer: Where is the figure??

Stella is using her compass and straightedge to complete construction of a polygon inscribed in a circle. Which polygon is she in the process of constructing?
Answer:
A regular pentagon
Step-by-step explanation:
A pentagon has 5 sides. There are 5 tick marks.
The answer polygon is a Hexagon.
What is a hexagon?A hexagon is a six-sided polygon. Hexagon has some special properties when we are talking about inscribed polygons.
Two vertices of the hexagon lie on the corners of the diameter of the circumscribing circle.
Given that, Stella is using her compass and straightedge to complete the construction of a polygon inscribed in a circle.
We are asked which polygon is she in the process of constructing.
Since, there are 6 marks on the circle, which is one of the step for constructing a hexagon.
So, We can say that she is constructing a regular hexagon inside the circle.

if you plot this on a scatterplot, would the correlation be strong or weak?? EXPLAIN! ( temperature is x and sales is y)
Answer:
Strong Correlation
Step-by-step explanation:
If the numbers of the sales are matched in order with the temp., this is a strong correlation. I'm assuming the question is asking you to prove the correlation between the change in temperature, and the change in hot chocolate sales.
If you match the numbers, you'll see that when its colder outside, hot chocolate sales go up. When it's hot out side, sales go down. This is a strong, inverse correlation.
Then again, if these numbers are out of order in any way, my entire answer goes down the drain. Make sure all information is included in your question, including pictures :)

son for $4.75. If Julio pays for the tickets and the souvenir with a $100 bill, how
much change will he receive?
Find the total he spent and subtract that from 100:
12.50 x 4 = 50
50 + 4.75 = $54.75 total spent

On the last 5 quizzes, Marco has earned a total of 21 out of 25 possible points. If he has a perfect score on the next several quizzes, exactly how many points will he need to bring his average up to 90%?
(a)Write a rational equation to represent this situation
(b) Solve the equation and show how how you got your answer.
A) The rational equation that represents the given situation in the question is; (21 + x) = 0.9(25 + x)
B) Solving the equation gives the number of points needed to bring his average to 90% as; 15 points
We are told that he earned a total of 21 out of 25 possible points.
A) Now, if he has a perfect score on the next several quizzes, it means the number of points which we will call x that he needs to bring his average up to 90% is calculated from the rational equation;
(21 + x)/(25 + x) = 90%
⇒ (21 + x)/(25 + x) = 0.9
⇒ (21 + x) = 0.9(25 + x)
B) To find the number of points, let us solve the equation in A above to get;
(21 + x) = 0.9(25 + x)
Using distributive property on the right hand side, we have;
21 + x = 0.9(25) + 0.9x
21 + x = 22.5 + 0.9x
Using subtraction property of equality;
x - 0.9x = 22.5 - 21
0.1x = 1.5
x = 1.5/0.1
x = 15 points

mixed numbers multiple 4 1/2 x 1 2/3
Answer:
7 1/2
Step-by-step explanation:
So, we have the problem 4 1/2 x 1 2/3.
Lets convert both of these mixed fractions into improper fraction, because it would be much easier to multiply.
4 1/2= 9/2 as an improper fraction
1 2/3= 5/3 as an improper fraction
Now, lets multiply!
9/2 x 5/3
Lets multiply the numerators first.
9 x 5 is 45
Now, the denominators.
2 x 3 is 6
So, 9/2 and 5/3 is 45/6
Lets convert 45/6 into its mixed fraction form
45/6 as a mixed fraction would be 7 1/2
Hope this helped :)
