A rectangular pool is 6 feet long and 5 feet wide. It is filled to a depth of 2 Teet. A cubic footof water is about 7.5 gallons. If the pool can be filled at a rate of about 10 gallons per minute, now long will it take to fill the pool to a depth of 2 feet? Explain your reasoning. *QUICK*

450 minutes

Step-by-step explanation:

First, let's calculate the volume of the pool when filled.  Volume will be: (length x width x height).

Volume = 6' x 5' x 2 ' = 60 ft^3

1 ft^3 of water occupies 7.5 gallons.  That's a conversion factor for water:  (7.5 gal)/(1 ft^3).

The total gallons of water in a filled pool would be:\

(60 ft^3)*((7.5 gal)/(1 ft^3)) = 4500 gallons

At a rate of 10 gallons/min, it would take:

(4500 gallons)/(10 gallons/min) = 450 minutes, or 450/60 = 7.5 hours

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.
