Flat Figures: Sides and Vertices

Medium

(Originais Teachy 2023) - Question Medium of Mathematics

A farmer wants to fence a plot of land to plant different crops in order to optimize his space. However, he notices that the shape of the land is a polygon with 8 sides and 8 vertices. In order to calculate the necessary amount of stakes to fence the land, he needs to correctly identify the type of polygon he has. Considering that he already has 7 stakes positioned at the vertices of the land, he wants to know how many additional stakes are needed to complete the fence. What is the correct classification of the polygon in question and how many additional stakes does the farmer need to completely fence his land, considering that each vertex of the polygon must be connected by a straight line segment of fence?
a.
The polygon in question is a decagon and the farmer needs 8 additional stakes to completely fence his land.
b.
The polygon in question is a pentagon and the farmer needs 10 additional stakes to completely fence his land.
c.
The polygon in question is an octagon and the farmer needs 7 additional stakes to completely fence his land.
d.
The polygon in question is a hexagon and the farmer needs 9 additional stakes to completely fence his land.
e.
The polygon in question is an octagon and the farmer needs 9 additional stakes to completely fence his land.

In a civil engineering project, an architect needs to divide a rectangular plot of land into two equal parts for the construction of two semi-detached houses. The coordinates of the vertices of the land on the Cartesian plane are A(0, 0), B(30, 0), C(30, 20), and D(0, 20). Using concepts of analytic geometry, determine the coordinates of the point that represents the midpoint of side CD of the land, which will be the dividing point between the two new properties. Then, verify if the obtained midpoint point is indeed on segment CD, ensuring the accuracy of the project. Explain the reasoning used to determine the coordinates and to verify the positioning of the midpoint on the land.

João is organizing a birthday party and wants to make a larger quantity of his favorite cake recipe. The original recipe yields a cake with 20 slices and uses 3 cups of flour, 2 cups of sugar, and 1 cup of oil. João wants to make a cake with 40 slices. a) How many cups of flour, sugar, and oil should he use to make a cake that yields 40 slices? b) If he wanted to make a cake with 60 slices, what would be the quantity of cups of each ingredient? c) João noticed that the number of cake slices is always half the number of cups of water used in the recipe. How many cups of water are needed for a cake of 80 slices?
