Multiply 1.75 with 25 because you bought snacks everyday and then you’re left with 11.25

Now subtract .20 because you were left with that on day 26 and you get 11.05

Lastly you divide 11.05 with .85 to see how many snacks you bought

ANSWER IS 13 snacks

Find the perimeter of the pentagon with vertices M(-2,5), N(2,5), P (5, 3),
wlad13 [49]

The perimeter of the pentagon is approximately 19.6.

<h3>Procedure - Determination of the perimeter of a pentagon</h3><h3 />

In this question we must plot the locations of each vertex on a Cartesian plane to determine the line segments that form the perimeter, whose lengths are determined by Pythagorean theorem and sum the resulting values to find the perimeter.

According to the image attached below, the line segments of the pentagon are MN, NP, PQ, QR and RM. By Pythagorean theorem we have the following lengths:

<h3>Line segment MN</h3><h3 /><h3>l_{MN} = \sqrt{[2-(-2)]^{2}+(5-5)^{2}} </h3><h3>l_{MN} = 4</h3><h3 /><h3>Line segment NP</h3><h3 /><h3>l_{NP} = \sqrt{(5-2)^{2}+(3-5)^{2}}</h3><h3>l_{NP} = \sqrt{13}</h3><h3 /><h3>Line segment PQ</h3><h3 /><h3>l_{PQ} = \sqrt{(5-5)^{2}+(0-3)^{2}}</h3><h3>l_{PQ} = 3</h3><h3 /><h3>Line segment QR</h3><h3 /><h3>l_{QR} = \sqrt{(3-5)^{2}+(3-0)^{2}}</h3><h3>l_{QR} = \sqrt{13}</h3><h3 /><h3>Line segment RM</h3><h3 />

l_{RM} = \sqrt{(-2-3)^{2}+(5-3)^{2}}

l_{RM} = \sqrt{29}

And the perimeter of the pentagon is:

p = l_{MN} + l_{NP} + l_{PQ} + l_{QR} + l_{RM} (1)

p = 4 + \sqrt{13} + 3 + \sqrt{13} + \sqrt{29}

p = 7 + 2\sqrt{13} + \sqrt{29}

p \approx 19.6

The perimeter of the pentagon is approximately 19.6. \blacksquare
