Answer:

$\large\boxed{0.6\overline{12}=\dfrac{101}{165}}$

Step-by-step explanation:

$x=0.612121212...\qquad\text{multiply both sides by 10}\\\\(1)\qquad10x=6.12121212...\qquad\text{multiply both sides by 100}\\\\(2)\qquad1000x=612.12121212...\qquad\text{subtract (1) from (2)}\\\\1000x-10x=612.12121212...-6.12121212...\\\\990x=606\qquad\text{divide both sides by 990}\\\\x=\dfrac{606}{990}\qquad\text{simplify}\\\\x=\dfrac{606:6}{990:6}\\\\x=\dfrac{101}{165}$

I believe it would be dilated by 3/4

If you think of a rectangle, let’s say it is 8 by 4, the perimeter of this rectangle would be 24.

Now if you dilate the side values, you get 6 by 3 and the perimeter equals 18

So you then get 18/24 which is equal to 3/4

Hope this is right and makes sense! Have a good day!

Amanda only has $30 to buy pens and notebooks. Each pen costs $2. Each notebook coats $3. Which of the following graph represent

sineoko [7]

Answer:

3p + 8n, 12p + 2n, 9p+4n, 6p+6n

8 columns bar graph.

Step-by-step explanation:

$2 = pen

$3 = notebook

This could be written as a bar graph in multiples of $6.00 along y axes.

3 pens + 8 notebooks. Then 12 pens + 2 notebooks.

Then 9 pens + 4 notebooks . Then 6 pens + 6 notebooks

3p + 8n, 12p + 2n, 9p+4n, 6p + 6n

3p = $6

8n = $24

12p = $24

2n = $6

9p = $18

4n = $12

6p = $12

6n = $18

and so on...

100 POINTS!!! VERY URGENT

Marta_Voda [28]

Answer:

Step-by-step explanation:

f(x) = 10x² + 3

g(x) = x - 3

⇒ (f o g)(x)

⇒ f(x - 3)

⇒ f(x - 3) = 10(x - 3)² + 3

⇒ f(x - 3) = 10(x² - 6x + 9) + 3

⇒ f(x - 3) = 10x² - 60x + 90 + 3

⇒ <u>(f o g)(x) = 10x² - 60x + 93</u>
