Jane was assigned a project to number and colour desks based off certain criteria. If the desk was brown, she would label it in multiples of 4 (where the first is 4, the
second is 12, etc.) and the colour would remain the same. If the desk was white, she
would number the desk in multiples of 5 (where the first is 5, the second is 10, etc.)
and colour those that she numbered with an even number green. If there were
originally 5 brown desks and 6 white desks, what fraction of the even numbered
desks will be coloured green?

5/3 or 3/5

Step-by-step explanation:

If there were 5 brown desk, it will be:

4,12,36,108,304

If there were 6 white desk, it will be:

5,10,15,20,25,30

Putting them it fraction: brown/white:

5/3

If putting them in this fraction: white/brown:

3/5

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
