The second picture represents the same relation between x and y and the proportional ratio of dollar to month is \boxed{\$ 50{\text{ per month}}}.

Further explanation:

The relation is defined as the relationship between the input values and output values.

In the interval \left({x,y}\right) the first value represents the x and the second value is y.

The x coordinates are the domain of the function and the y coordinates are the range of the function.

Explanation:

The ratios of x and y of first picture can be calculated as follows,

\dfrac{1}{5}\dfrac{3}{{12}}=\dfrac{1}{3}

The ratios of x and y are not equal. Therefore, in the first picture x and y are not in a proportional relationship.

The ratios of x and y of second picture can be calculated as follows,

\begin{aligned}\frac{1}{3}\\\frac{2}{6}&=\frac{1}{3}\\\frac{4}{{12}}&= \frac{1}{3}\\\frac{5}{{15}}&=\frac{1}{3}\\\end{aligned}

The ratios of x and y are equal. Therefore, in the second picture x and y are in a proportional relationship.

\begin{aligned}\Dfrac{0}{4}&= 0\\\dfrac{2}{8}&=\frac{1}{4}\\\end{aligned}

The ratios of x and y are not equal. Therefore, in the third picture x and y are not in a proportional relationship.

The ratios of x and y of fourth picture can be calculated as follows,

\begin{aligned}\frac{1}{4}&=\frac{1}{4}\\\frac{2}{{10}}&=\frac{1}{5}\\\end{aligned}

The ratios of x and y are not equal. Therefore, in the third picture x and y are not in a proportional relationship.

The ratio of dollars to months can be obtained as follows,

\begin{aligned}\frac{{100}}{2}&= 50\\\frac{{150}}{3}&= 50\\\frac{{250}}{5}&= 50\\\frac{{400}}{8}&= 50\\\end{aligned}

The dollars and months are in a proportional with ratio 50:1.

The second picture represents the same relation between x and y and the proportional ratio of dollar to month is \boxed{\$ 50{\text{ per month}}}.

The length of a rectangle is twice its width. if the area of the rectangle is 200 yd2 , find its perimeter.
Lorico [155]
Width: x
Length: 2x
Area=x(2x)=2x^2
2x^2=200
x^2=100
x=10 or -10(reject as x>0) [width cannot be less than 0, doesnt make sense]
Perimeter
=x+x+2x+2x
=6x
=6(10)
=60 yd

Verizon [17]
The answer is:  "40 cm " .
_________________________________________________________
<u>Note</u>:
_________________________________________________________

\frac{200 ft }{ (x) cm} = \frac{5}{1}  ;

Solve for "x" (in "cm" ) ; 


→  5x = 200 * 1 ; 

→  5x = 200 ; 

Divide each side of the equation by "5" ; 
   to isolate "x" on one side of the equation; & to solve for "x" ; 

→  5x / 5 = 200 / 5 ; 

to get:

→  x = 40 .

The answer is:  " 40 cm " .
