How many dollars do you have if you have 90 nickels, 16 dimes, 16 quarters, and 7 fifty-cent pieces? Show your work and explain each step.

$13.60

Step By Step:

A nickle is worth 5 cents.

A dime is worth 10 cents.

A quarter is worth 25 cents.

5 Cents • 90 Nickles = 450

10 Cents • 16 Dimes = 160

25 Cents • 16 Quarters = 400

50 Cents • 7 fifty-cent pieces = 350

450 + 160 + 400 + 350 = 1360

A dollar is worth 100 cents.

1360 ÷ 100 = $13.60

Step-by-step explanation:

You have 90 nickels

Since 20 nickels = 1 dollar you have 4 dollars and 10 nickels left over

The ten nickels left = 1/2 a dollar or 50 C

You have 16 dimes

10 dimes = 1 dollar

You have 1 dollar and 6 dimes left over.

So you have 1 dollar and 60 C

You have 16 quarters.

4 Quarters = 1 dollar

16/4 = 4 dollars. No quarters are left over.

You have 7 fifty-cent pieces

2 fifty cent pieces = 1 dollar

7/2 = 3 dollars and 50 cents left over.

I don't exactly know what you want as a final answer, but here is what I think it is

nickels =                     4 dollars and 50 cents

dimes   =                     1 dollar and   60 cents

quarters                      4 dollars

fifty cent pieces          3 dollars        50 cents

Adjustments                 1                     60 cents*

Totals                           13                    60 cents.

*The adjustment comes from 2 values of 50 cents each and 60 cents which cannot be combined with anything.

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 !
