Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have the point (1/4,3/8)
The constant of proportionality k is equal to
substitute the value of y and the value of x of the given ordered pair
Multiply in cross

Answer: 43.3 inches.
Step-by-step explanation:
According to the Pythagorean Theorem:
Where "a" is the hypotenuse, and "b" and "c" are the legs of the right triangle.
Let be "c" the width of the television.
We can indentify in the figure that:
Then, we can substitute values and solve for "c":
Rounded to the nearest tenth:
and
. So we have a remainder of
and
. Subtracting this from the previous remainder gives a new remainder
and
. Subtracting this from the previous remainder gives a new one of
and we're done since 2 does not divide . So we have
