Answer: 9 books per day

Step-by-step explanation:

27 books / 3 days = 9 books per day

[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:

Simplify:

Final expression: [tex]\frac{\sqrt6 + 2}{2}[/tex]

_______________________________________________________

A 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.

Answer:

-35.148

I don't know if you need to round the answer or not

Step-by-step explanation:

Hello there!

[tex]\sf \longmapsto 1.12 \: \times ( - 2.9)[/tex]

This is a arithmetic expression.We need to find the result of it.

[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]

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

Answer:

Slope = ¼

Step-by-step explanation:

Given the following points from the graph, (0, 1) and (8, 3):

Let (x₁, y₁) = (0, 1)

     (x₂, y₂) = (8, 3)

Substitute these values into the following slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - 1)/(8 - 0) = 2/8 = ¼

m = ¼

Therefore, the slope of the given graph is ¼.

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 :)

Answer:

A number k is less than or equal to 10

given,

measure of sides of the square = 12 cm

we know, diagonal

d = a√2

now,

d = 12√2

d = 16.970

a/q we have to round the answer to the nearest centimetres

so,

it is 17 cm

Answer:

A regular pentagon

Step-by-step explanation:

A pentagon has 5 sides. There are 5 tick marks.

The answer polygon 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.

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
