In a company, the ratio of the number cashiers is 20:3. If there are 120 workers in the company, how many cashiers are there ?

(A)17
(B)18
(C)21
(D) 23

9514 1404 393

  (B)  18

Step-by-step explanation:

Multiply each of the numbers in the ratio by 6.

  workers : cashiers = 20 : 3 = 120 : 18

There are 18 cashiers for 120 workers.

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.
