Bus A and Bus B leave the bus depot at 6 am. Bus A takes 20 minutes to do its route and bus B takes 35 minutes to complete its route. At what time are they both back at the bus depot together? Give your answer as a 12-hour clock time.

We have been given that Bus A and Bus B leave the bus depot at 6 am. Bus A takes 20 minutes to do its route and bus B takes 35 minutes to complete its route.

We are asked to find the time when the both buses will be back at the bus depot together.

We need to find least common multiple of 20 and 35 to solve our given problem.

Prime factorization of 20: .

Prime factorization of 35:

Least common multiple of 20 and 35 would be .

This means that both buses will be back at the bus depot together after 140 minutes.

Let us convert 140 minutes into hours.

Both buses will be back at the bus depot together after 2 hours  and 20 minutes after 6 am.

Since 2 hours and 20 minutes after 6 am would be 8:20 am, therefore, both buses will be back at the bus depot together at 8:20 am.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

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 !
