#rooms cleaned in 1 hour # meals cooked in 1 hour
jacob 2 4
william 3 9
what is the minimum william would need to receive from jacob to be willing to cook another meal?
a) 1/3 of a clean room
b) 1/2 of a clean room
c) 2 clean rooms
d) 3 clean rooms

a) 1/3 of a clean room

Step-by-step explanation:

First at all, we need to calculate how much takes Jacob cleaning a room.

So we divide 1 hour by 2 rooms

1 hour = 60 min

and

Now, we must to know how much takes William to cook a meal:

In 60 minutes William cooks 9 meals

so we have:

that means William spends 6 minutes and 40 sec cooking a meal.\

Now we can solve:

In 6 minutes and 40 sec, how many rooms can Jacob clean?

We know Jacob spend 30 minutes cleaning a room so in 10 minutes or 1/3 of a clean room Williams had already cooked another meal. Thus, the closest answer is a)1/3 of a clean room.

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.
