Answer:

\dfrac{x+y}{2}

Step-by-step explanation:

Let first number be x and another number is y.

A rational number is a fraction that can be expressed in the form of x/y.

A rational number between x and y is given by :

R=\dfrac{x+y}{2}

So,

If x and y are two rational numbers such that x < y , then \dfrac{x+y}{2} is a rational number in between x and y.

The linear scale factor of two shapes is 3:4. If the area of the smallest shape is 72^2 what is the area of the big shape?​
Lorico [155]

Answer:

\boxed{6912 units^2}

Step-by-step explanation:

<em>Hey there!</em>

Well using the given ratio,

3:4

And the area of the small shape we need to do,

72*72 = 5184

Now we can make the following fractions,

\frac{3}{4} = \frac{5184}{x}

Now we can solve,

3*x = 3x

4 * 5184 = 20736

3x = 20736

20736 / 3

x = 6912

So the area of the bigger shape is 6912 units^2

<em>Hope this helps :)</em>
