Ruben put an empty cup underneath a leaking faucet. after 1 1\2 hours, ruben collected 1/4 cup of water. what is the rate, in cups per hour, at which the water is leaking from the faucet?

6 cups per hour.

Step-by-step explanation: You divide 1 1/2 by 1/4. So then you turn the mixed number into an improper fraction. To do this, you multiply the denominator by the whole number, so 2 times 1 and then add the numerator, so three. then you do 3/2 divided by 1/4. Then, you do Keep Change Flip. This applies to every division problem with fraction.  Keep 2/3, change the division symbol to multiplication, and then flip the fraction from 1/4 to 4/1. Then you multiply straight across. Numerator times Numerator. So 3 times 4, which is 12. And then denominator times denominator 2 times 1. You then get 12/2, equal to 6. So 6 cups per hour.

a=r

d=q

c=p

b=s

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.
