Alocal theater sells admission tickets for $9.00 on thursday nights. at capacity, the theater holds 100 customers. the function m(n) = 9n represents the amount of money the theater takes in on thursday nights, where n is the number of customers. what is the domain of m(n) in this context? select the correct answer. a all whole numbers b all non-negative rational numbers c all non-negative integers that are multiples of 9 d all non-negative integers less than or equal to 100

answer: its the third option.

step-by-step explanation:

i just took the test.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
