Question

K varies directly with F. If K = 36, F = 8, then what is the value of K when F = 12?
a)35
b)60
c)42
d)54​

Answer 1

Step-by-step explanation:

K: F:

36 ------------8

x--------------12

$x = \frac{12 \times 36}{8} = 54$

Answer 2

Concept :

In other words, a variable is a labeled container for a specific set of bits or nature of the data. A variable is a conceptual storage place linked with a symbolic name that stores some known or unknown array of data referred to as a value. A variable is a name or reference to information that is symbolic in nature. What information is in a variable is indicated by the variable's name. They are referred to as variables because the information represented by them might change while the actions on them stay the same. Any qualities, quantity, or number that can be gauged or tallied qualifies as a variable.

Given:

K varies directly with F.

$K = 36, F = 8$.

Find:

The value of K when $F = 12$

Solution:

According to the problem,

Let the value of K is x when $F = 12$

when $K = 36, F = 8.$

So, when $F = 12$

$x =$  $( 12$ × $36 ) / 8 = 54$

Hence the value of K will be $54$
