Ahomeowner has decided to fill in his in-ground pool because it is no longer used. assume the pool is rectangular and measures 20 feet wide, 40 feet long, and 5.5 feet deep throughout. each cubic yard of fill dirt costs $12. how much will it cost to fill in the pool? assume that he must purchase full cubic yards only, even if that means buying more than he needs.

So for this problem we need to find the volume. The formula for volume is

l * w * h

40 * 20 * 5.5 = 4400

So now you need to put ft into yards

4400ft = 1466.667

Now multiply this by 12

1466.667 * 12 = 17600.004

Because you cant have $00.004 I believe that for this equation you would round to the nearest hundred, so that would be $17600.01.

Your answer is $17600.01

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 !

for future students the answer is b
