A university is trying to determine what price to charge for tickets to football games. at a price of $20 per ticket, attendance averages 40,000 people per game. every decrease of $5 adds 10,000 people to the average number. Every person at the game spends an average of $5.00 on concessions. what price per ticket should be charged in order to maximize revenue? How many people will attend at that price?

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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.  

(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

not sure but it may be b, as i said i'm not sure.
