A fish tank contains 24 L of water. Water is added to increase the volume by 12.5%. What is the new volume of water in the tank?
Ronch [10]

If y= 1/5 when x=3, find y when x=4, given that y varies directly with x
lisov135 [29]

Answer:

<h2>y =  \frac{4}{15}</h2>

Step-by-step explanation:

To find y when x=4, we must first find the relationship between them

The statement

y varies directly with x is written as

<h3>y  \:  \:  \:  \alpha  \: \:   \: kx</h3>

where k is the constant of proportionality

From the question

when y = 1/5

x = 3

Substitute the values into the above formula and solve

That's

<h3>\frac{1}{5}  = 3k \\ 15k = 1 \\ k =  \frac{1}{15}</h3>

So the formula for the variation is

<h3>y =  \frac{x}{15}</h3>

From the question

when x = 4

<h3>y =  \frac{4}{15}</h3>

Hope this helps you
