At a pet store customers can pay 12.50 for a fish tank and $.20 for each fish. what is the rate of change in the situation described?

At a pet store a customer can buy up to 63 fishes , with $0.20 per fish as he have $12.50 . With every $0.20 , customer can buy 1 fish i.e. rate is $0.20 per fish !

Step-by-step explanation:

Here we have , At a pet store customers can pay 12.50 for a fish tank and $.20 for each fish. We need to find what is the rate of change in the situation described . Let's find out:

It's given that each fish cost $0.20  , and a customer pays 12.50 . So , the number of fishes is bought is :

⇒

⇒

⇒

Rounding off ,

⇒

Therefore, At a pet store a customer can buy up to 63 fishes , with $0.20 per fish as he have $12.50 . With every $0.20 , customer can buy 1 fish i.e. rate is $0.20 per fish !

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.
