Rose bought some spinach she used 3/5 of the spinach on a pan of spinach pie for a party and 3/4 of the remaining spinach for a pan for her family she used the rest to make a salad. If rose used 3 pounds of spinach to make the pan of spinach pie for the party how many pounds of spinach did rose use to make the saled

Total pounds of spinach = 5 pounds

Pounds used for salad = 0.5 pounds

Step-by-step explanation:

Let

Total spinach = x

She used pan of spinach pie for a party = 3/5x

Remaining spinach = x - 3/5x

= 5x-3x/5

= 2/5x

She used 3/4 of the remaining spinach for a pan for her family

3/4 of 2/5x

= 3/4 × 2/5x

= 6/20x

= 3/10x

she used the rest to make a salad.

Salad = x - (3/5)x - (3/10)x

= (1 - 3/5 - 3/10)x

= (10-6-3/10)x

= 1/10x

If rose used 3 pounds of spinach to make the pan of spinach pie for the party how many pounds of spinach did rose use to make the saled

She used pan of spinach pie for a party = 3/5x

3/5x = 3 pounds

Divide both sides by 3/5

x = 3 ÷ 3/5

= 3 × 5/3

x = 5 pounds

Salad = 1/10x

= 1/10 * 5

= 5/10

= 0.5 pounds

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 !
