An airline offers the same number of tickets for morning and night flights. when the airline analyzed ticket sales,
they determined that the ratio of the number of sold tickets to the number of unsold tickets was 3: 5 on morning
flights and 7: 1 on night flights. if the airline sells 581 tickets on night flights, how many unsold tickets can the
airline expect on morning flights?

The number of unsold tickets the airline can expect on morning flights is 414.

Step-by-step explanation:

step 1

Find out the total number of tickets on night flights

Let

x ----> number of sold tickets

y ----> number of unsold tickets

we know that

Isolate the variable y

----> equation A

----> equation B

substitute the value of x in the equation A

The total number of tickets is

step 2

Find out how many unsold tickets can the  airline expect on morning flights

Remember that the total number of tickets on night flights is the same number for morning flights

so

----> equation A

-----> equation B

substitute equation B in equation A and solve for y

therefore

The number of unsold tickets the airline can expect on morning flights is 414.

answer: need picture of problem

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
