You use a garden hose to fill a wading pool. If the water level rises 17 centimeters every 7 minutes and you record the data point of (21,y), what is the value of y?

Value of y is 51.

Step-by-step explanation:

Given:

A garden hose is used to fill a pool where water level rises 17 cm in every 7 minutes.

And the recorded data given = (21,y)

We have to find the value of "y".

As the ascent of water level is upward so we will assign it y-axis and time to be on x-axis.

As we know in Coordinate plane we have to put data.

So,

Rise of cm in minutes can be written in as .

Lets find the relation of given with and say that its ratio is a factor.

Dividing both the values:

⇒

⇒

⇒

We can say that the ratio of y-values will also be equal to   .

⇒

⇒     ...considering  

⇒

⇒

⇒

⇒

The value of y from the data point is 51.
