Sarah drove 40 miles per hour. in 3 hours, sarah drove 120 miles. what is a valid proportion to represent the problem?

As per the statement:

Sarah drove 40 miles per hour in 3 hours,  Sarah drove 120 miles.

Since, speed(s) is proportional to time(t)

Using Inverse proportional.

⇒, where, d is the constant distance

We can write this as:

or

Check:

Sarah drove 40 miles per hour in 3 hours

⇒s = 40 miles per hour and t = 3 hours

then;

⇒Sarah drove 120 miles.

therefore, a valid proportion to represent the problem is,

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 !

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
