Help me please i am stuck

Angel observes a marble travel along a horizontal path at a constant rate. The marble travel 2/3 of the length- of the path in 50 seconds. At that rate, how many seconds does it take the object to travel the full length?                                

Step-by-step explanation: First, reason down from 2/3 to 1/3. Enter all values as fractions (proper or improper) or whole numbers. You will need to  convert mixed numbers to improper fractions.

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.

answer: do we write it
