Order number from least to greates <br> 9/5 -2.5 -1.1 -4/5 0.8

Brut [27]

Answer:

Step-by-step explanation:

Start by writing these five numbers in just one format (improper fractions with denominator 10):

9/5 = 18/10, and

-2.5 = -25/10, and

-1.1 = -11/10, and

-4/5 = -8/10, and, finally

0.8 = 8/10

The smallest of these (the least) is -25/10, and

the largest is 18/10.

Arranged in ascending order, we have:

-25/10, -11/10, -8/10, 8/10, 18/10, or

-2.5, -1.1, -4/5, 0.8, 9/5

For for every ten sheets of stickers you buy at a craft store the total cost increases $20.50

Len [333]

The equation which relates the change in price per sticker purchased is y = 2.05x

The number of stickers purchased = 10

Price change = $20.50

The change in price per sticker purchased can be expressed as :

Price change / number of stickers

Change in price per sticker = $20.50 / 10

Change in price per sticker purchased = 2.05

Therefore, the required equation which related y and x is :

y = 2.05x

Rationalize the denominator of $\frac{5}{2+\sqrt{6}}$. The answer can be written as $\frac{A\sqrt{B}+C}{D}$, where $A$, $B$, $C$

horrorfan [7]

Answer:

$A +B+C+D = 3$ is the correct answer.

Step-by-step explanation:

Given:

$\frac{5}{2+\sqrt{6}}$

To find:

$A+B+C+D = ?$ if given term is written as following:

$\frac{A\sqrt{B}+C}{D}$

<u>Solution:</u>

We can see that the resulting expression does not contain anything under $\sqrt$ (square root) so we need to rationalize the denominator to remove the square root from denominator.

The rule to rationalize is:

Any term having square root term in the denominator, multiply and divide with the expression by changing the sign of square root term of the denominator.

Applying this rule to rationalize the given expression:

$\dfrac{5}{2+\sqrt{6}} \times \dfrac{2-\sqrt6}{2-\sqrt6}\\\Rightarrow \dfrac{5 \times (2-\sqrt6)}{(2+\sqrt{6}) \times (2-\sqrt6)} \\\Rightarrow \dfrac{10-5\sqrt6}{2^2-(\sqrt6)^2}\ \ \ \ \ (\because \bold{(a+b)(a-b)=a^2-b^2})\\\Rightarrow \dfrac{10-5\sqrt6}{4-6}\\\Rightarrow \dfrac{10-5\sqrt6}{-2}\\\Rightarrow \dfrac{-5\sqrt6+10}{-2}\\\Rightarrow \dfrac{5\sqrt6-10}{2}$

Comparing the above expression with:

$\frac{A\sqrt{B}+C}{D}$

A = 5, B = 6 (Not divisible by square of any prime)

C = -10

D = 2 (positive)

GCD of A, C and D is 1.

So, $A +B+C+D = 5+6-10+2 = \bold3$
