Answer:

las fracciones decimales son:

21/10 = 2,1

439/100 = 4,39

34/10 = 3,4

35/1000 = 0,035

851 / 1000 = 0,851

Step-by-step explanation:

Toda fraccion cuyo denominador (el numero de abajo) es multiplo de 10 es considerada una fraccion decimal. No importa si el numerador es mayor al denominador. Justamente el sistema decimal fue concebido para facilitar la multiplicacion y division de los numeros por algun multiplo de 10.

Last Month, Levi had written 125 words of his book. This month,he is up to 12,580 words. About how many times more words has he
VladimirAG [237]

Answer:

He has written about 100 times as many words.

Step-by-step explanation:

In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.

12,580 - 125 = 12,455

Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.

12,455/125 = 99.64 times more, or rounded, about 100 times more.

On this corrdinate plane UVW has been transformed to form image U’ V’ W’.
egoroff_w [7]

Answer:

C

Step-by-step explanation:

Translate the image 2 units right and 1 unit up. Then rotate the image 180°.

Take the coordinate W, it is at (2, 4).

Translate 2 units right (add 2 to the x coordinate) and 1 up (add 1 to the y coordinate)

(2, 4) ------> (2 + 2, 4 + 1) -------> (4, 5)

A rotation of 180° (doesn't matter the direction) makes the coordinates their opposites. Positives become negatives and negatives become positive.

(4, 5) -------> (-4, -5)

Need help ASAP!!!!! I WILL GIVE THE MOST BRAINLIEST TO THE FIRST PERSON THAT ANSWERS
lys-0071 [83]

Answer:

x^2 + 10x + y^2 -4y + -7 = 0

Step-by-step explanation:

For any circle point with coordinate of center (a,b) and radius r

equation of circle is given by

(x-a)^2 + (y-b)^2 = r^2

_______________________________________

Given

coordinate of center =  (-5,2)

radius = 6

thus, equation of circle can be written by substituting a and b with (-5 ,2) and r =6 as shown below

(x-a)^2 + (y-b)^2 = r^2\\(x-(-5))^2 + (y-2)^2 = 6^2\\x^2 + 10x + 25 + y^2 -4y + 4 = 36\\=>x^2 + 10x + y^2 -4y + 29 = 36\\=>x^2 + 10x + y^2 -4y + 29 -36 = 36 -36\\=>x^2 + 10x + y^2 -4y + -7 = 0

Thus, equation of circle is x^2 + 10x + y^2 -4y + -7 = 0
