How many 52-seater buses does a
school need for 198 pupils and staff?

4

Step-by-step explanation:

198 pupils divided by 52 seats gives you 3.8 you can't have half a bus so you to round it up to give 4 depending on how many staff may need to increase

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.
