Answer:

The third option, -1/2(30) = -15

Step-by-step explanation:

If it decreases by 1/2, we know it has to be -1/2, and the days we are given are 30. We need to multiply -1/2 by 30 in order to find the water level after 30 days, which would be -15 (inches?) I hope this helped.

Given:

Triangle EFG is similar to triangle HIJ.

To find:

The measure of side IJ.

Solution:

We know that, corresponding sides of similar triangles are proportional.

Triangle EFG is similar to triangle HIJ.

\dfrac{EF}{HI}=\dfrac{FG}{IJ}

Putting the given values, we get

\dfrac{7}{32}=\dfrac{4}{IJ}

7\times IJ=4\times 32

IJ=\dfrac{128}{7}

IJ=18.2857

IJ\approx =18.3

Therefore, the measure of side IJ is 18.3 units.
