Jeanine’s swimming pool has a diameter of 27 feet. Surrounding the pool is a
deck that extends 5 feet from the edges of the pool. Jeanine wants to paint the deck and then put a fence around it. Paint costs $0.85 per square foot and fencing costs $8.25 per foot. How much will it cost Jeanine to paint the deck and add fencing? Explain how you found your answer.

It will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck

Step-by-step explanation:

Diameter of swimming pool = 27 feet

Radius of pool r=

Surrounding the pool is a  deck that extends 5 feet from the edges of the pool

Outer radius R = 13.5+5=18.5

Area of deck = Outer area - Inner area

Area of deck =

Area of deck =

Area of deck =

Cost of painting 1 sq.feet = $0.85

Cost of painting 502.4 sq.feet =

Perimeter of deck =

Cost of fencing 1 foot = $8.25

Cost of fencing 116.18 foot =

Hence it will cost $427.04 to paint deck and it will cost 958.485 to add fencing around deck

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
