Amarathon runner ran the first 4 mi
in 27.8 min. if she continues running
at this pace, how long will it take her
to run the entire marathon of 26.2 mi?

Step-by-step explanation:

4 miles / 27.8 min = 0.14388 miles per minute

26.2 / 0.143888 = 182.1 min

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.
