280 - 67 + 150 - 200

280 - 67 - 50

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.
