The answer is:  " [tex] \frac{4}{33} [/tex] "  .
______________________________
Given:  0.1212121212..... repeating ;  write that value as a fraction;
______________________________________________________
In other words; we are given:  "0.1212121212..... repeating infinitely" ;  

→ that is to say; "0.12 ...  ;  {the "12" decimal portion repeats infinitely} ; 
_______________________________________________________
→ We write this value, as a fraction, as:  "12/99" ;
__________________________________________
→Explanation:
__________________________________________ 


Note:  "0.99999999...... repeating infinitely;  =  "1" .
_________________________________________
→Since:

Let us say that we have: 

"x = 0.999999 ; repeating infinitely;  

In order words, let us say we have: "x = 0.9.... ;  the "9" decimal repeats infinitely; 
_____________________________________________________
   Then "10x" ;  (that is: "10" multlipled by "x";  or "10*x" or "10x" );  is equal to:

"10" * (0.999999.....)  = 9.99999999...... (the "9" decimal repeats infinitely);

in other words:  10x = 9.99999999....

Divide each side by "10" ;

to get "x = 0.9999999....." ; the decimal "9" repeats indefinitely...." ;

But if you have:  "10x = 10" ;  divide each side of the equation by "10" ; 
   you get: "x = 1" . 
____________________
Also,  if "x = 0.9999...(repeating infinitely); 

then:  10x = 9.99999.
_______________________________________________
           10x  =  9.999999999999999......
       −     x  =  0.999999999999999.......
    _____________________________________
            9x  =  9.00000000000000000000.....

 →  9x = 9 ; 

Divide each side of the equation; to get; 

 9x /9 = 9/ 9 ;  to get:  x = 1 ; and we have: x = 0.9999.... ;  so
  x= 0.99999.... = 1 ; 
__________________________________________________
So, if the numbers "12" is repeating, we divie "12" by "99" ; 
  that is; we divide "12" by "two 9's" ;  since "12" is a "TWO-digit number"; a "two-digit number" is being repeated infinitely.
________________________________________
            So;  0.12121212.....(the "12" is the decimal that repeats infinitely);            
                   
=  12/99 ;  which can be simplified;

Divide each side (both the numerator AND the denominator); by "3" ;
_________________________________________
  " 12/99 "  =  "(12÷3) / (99÷3) = 4/33 " .
_________________________________________
The answer is:  [tex] \frac{4}{33} [/tex]  .

answer is 4/33 hope this helps

Keira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints used for each mix and connected them using a line segment, as shown in the graph below:

Line graph Color Mix, Quantity of Blue Paint, in mm, on X axis and Quantity of Red Paint, in mm, on Y axis. X axis has a scale from 0 to 9 increments of 1. The Y axis has a scale of 0 to 18 increments of 2. Straight line connecting 3, 2 and 7, 12

Which statement best describes the domain of the function represented in the graph?

3 ≤ x ≤ 12 or x is between 3 and 12, inclusive
3 ≤ x ≤ 7 or x is between 3 and 7, inclusive
2 ≤ x ≤ 12 or x is between 2 and 12, inclusive
2 ≤ x ≤ 7 or x is between 2 and 7, inclusive

Answers

The most accurate statement is 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive.

The statement that best describes the domain of the function represented in the graph is 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive.

The domain of a function refers to all the possible input values (in this case, the quantity of blue paint) for which the function produces an output (the quantity of red paint).

Looking at the graph, we can see that the line segment starts at a blue paint quantity of 2 and ends at a blue paint quantity of 12.

Since the endpoints are included in the line segment, we know that the function is defined for all blue paint quantities between 2 and 12, inclusive.

Therefore, the most accurate statement is 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive.

Debra found that 6 of the 24 students in her class own a cell phone . What is the ratio of students that own a cell phone to students that do not ? Explain your reasoning to a classmate . ( please help)

Answers

If there are 24 total students, and 6 have a cellphone, then to find the students who do not own a cell phone, do 24-6=18. The ratio is 6:18, and when simplified, 1:3
If 6 students own a phone compared to the 24 that don't would be set up like this 1:4. This is because 24 divided by 6 equals 4. This means for every 1 student that has a phone, there are 4 students who don't have a phone.

During a canned food drive, Bob collected 6 times as many cans as Tom. If t represents the number of cans that Tom collected, which algebraic expression represents the number of cans that Bob collected?

Answers

Final answer:

The algebraic expression that represents the number of cans that Bob collected, given that t represents the number of cans that Tom collected, is 6t.

Explanation:

The algebraic expression that represents the number of cans that Bob collected, given that t represents the number of cans that Tom collected, is 6t. Since Bob collected 6 times as many cans as Tom, we can multiply the number of cans Tom collected by 6 to get the number of cans Bob collected.

If Bob collected 6 times as many cans as Tom, and if we represent the number of cans Tom collected with the variable t, then the algebraic expression that represents the number of cans that Bob collected is 6t. This is because if Tom collected t cans, then Bob, having collected 6 times more, would have collected 6 multiplied by t, which is simply represented as 6t.

Final answer:

The algebraic expression that represents the number of cans that Bob collected is 6t.

Explanation:

The algebraic expression that represents the number of cans that Bob collected is 6t. Since Bob collected 6 times as many cans as Tom, we can represent the number of cans that Bob collected by multiplying Tom's number of cans by 6. Hence, if t represents the number of cans that Tom collected, the expression 6t represents the number of cans that Bob collected.

Francois baked just enough cookies to fill all the orders at his bakery. While the cookies were cooling, a kitchen assistant knocked over a cooling rack and spilled %12, percent of the cookies onto the floor. Francois had to bake 36 more cookies to replace them. How many cookies were ordered in total?

Answers

300 cookies were ordered to start. 

We can tell this because we know 12% is equal to 36. Because this is true, we can set up a proportion to solve. All proportions can be set up with the small number on top and the total on the bottom. This will help you solve for the missing number, which is in this case the total number of cookies.  Let x be the total number of cookies.  

Percentage/total percentage = cookies/cookies total 
12/100 = 36/x

Now we can cross multiply to solve. 
(100)(36) = (12)(x) ----> multiply 
3600 = 12x ---> divide by 12
300 = x

For the equation below, x is the input and y is the output. Choose the ordered pair that makes a true statement for the equation.

Gerardo has an average of 83 on his five math tests. What must he score on his sixth test to raise his average to 85?

Answers

ANSWER: 95

Why?
83 is the average of 5 tests already taken. Each of the 5 tests would need 2 points added on in order to bring the average up to 85 (for those 5 tests). That means added 5 (tests) x 2 (extra points each) = 10 points to the 6th test to make up the difference.

10 + 85 = 95

A punter kicks a football upward with an initial velocity of 48 feet per second. After how many seconds does the ball hit the ground? use the formula h=rt-16t^2, where h represents height in feet and r represents the initial velocity (rate) in feet per second.

Answers

It would take 3 seconds for the ball to hit the ground

Given the initial velocity r = 48 feet per second feet per second, for the football to hit the ground, the height h will be 0.

Now, substitute the values, we have;

0 = 48t - 16t²

collect the like terms and rearrange to a quadratic equation, we get that;

16t² - 48t = 0

Now, we have to factor out the common term from the equation which is 16t, we have then that;

16t(t - 3) = 0

t- 3 = 0

collect the like terms, we get;

t = 3 seconds

What is the equation of the line shown in the graph? Write the equation in standard form?

Answers

The line is completely horizontal. Every point on this line has a y coordinate of -3. The x value is allowed to be anything you want. In this case x = -2 and x = 3 is shown for the two points.

Since y is fixed to always being -3, this means y = -3 is the equation. If you want it to fit standard form then you can write it as 0x+1y = -3

Notice how 0x+1y = -3 matches up with Ax+By = C where
A = 0
B = 1
C = -3

Simplifying 0x+1y = -3 leads back to y = -3
