Answer from: queeneaf

The addition of numbers on a number line is usually shown by an arrow pointing to the right for positive numbers and an arrow pointing to the left for negative numbers. The length of the arrow corresponds to the size of the number being added.

Here, you are apparently given a diagram that shows 0 + 7 + (-8) = -1. That is, you start at 0, move to the right 7 units as indicated by the arrow of length 7 directed to the right. Then you move to the left 8 units as indicated by the arrow of length 8 from 7 to -1. The ending point of the arrow represents the value of the sum (-1).

The appropriate choice is ...

Answer from: Quest

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 !

Answer from: Quest

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
