.. A = (1/2)*b*h
.. 36 in^2 = (1/2)*b*(9 in)
.. (72 in^2)/(9 in) = b . . . . . . . . multiply by 2, divide by 9 in
.. 8 in = b

The base is "none of the above", 8 inches.

This question has a couple of problems:

.. 2) ALL of the offered answer choices are INCORRECT.

What is the unit rate for the proportional relationship represented by the equation y=4/5x
slava [35]

Answer:

<em>the unit rate is 0.8x per unit y</em>

<em></em>

Step-by-step explanation:

the proportional relationship is y = \frac{4x}{5}

this means that the constant of proportionality k = \frac{4}{5} = 0.8

re-writing, we have

<em>y = 0.8x</em>

<em>therefore, the unit rate is 0.8x per unit y</em>
