Answer:
50
Step-by-step explanation:
We start with 56/154. Dividing each number by two, we have:
28/77
Dividing each number by seven, we have:
4/11
As the greatest common factor of 4 and 11 is 1, this fraction is in simplest form. Thus, 56/154 is equal to 4/11.

<span>hi, </span>
<span>you can determine it by seeing if y/x = a constant value, in other words if y = (a constant value) x </span>
<span>then you say that y varies directly with x, and you can see that : call the constant k </span>
<span>then y/x is supposed to be k in all values </span>
<span>6/3 = 2 </span>
<span>24/12 =2 </span>
<span>96/48 = 2 </span>
<span>384/192 = 2 </span>
<span>it worked the ratio between x and y is constant so y varies directly with x ( y = 2x) and that constant k =2 </span>
<span>p.s. you can also say that x varies directly with y but in that case it becomes x/y =constant and that constant say c is 1/2 (x = (1/2)y)) </span>
<span>hope u understand.

Option B: 
is the area of the compact disc.
Explanation:
The diameter of the compact disc is 
.
To determine the area of the compact disc, let us substitute the values in the area of the circle formula,
where 
Substituting the value of d in , we get,
Thus, 
and 
. Let us substitute these values in , we get,
Simplifying, we have,
Multiplying, we get,
Thus, the area of the compact disc is
Hence, Option B is the correct answer.
