Jack wants to buy the same number of hats for 3 of his friends. he has 57 dollars and each hat cost $5. what is the largest number of hats that jack buys for each friend.

3

Step-by-step explanation:

You know that he has $57 and 3 friends, so first lets figure out how much money each person gets. To do this, we have to take 57 and divide it by 3. 57÷3= 19.

Now that you know that each person gets $19 and you know that each hat costs $5, all you have to do it divide 19 by 5.

19÷5=3.8.

Since you can't have 0.8 of a hat, each person can only get 3 hats.

I hope this helps. ;)

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.
