The tape was 25 minutes long. What fraction of sixty minutes did the tape last?

12/5

Step-by-step explanation:

What fraction of 60 is 25, is just dividing 60 by 25.

That is:

= 60 ÷ 25

Divide the numerator and denominator by 5

= 12 / 5

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
