First multiply 12 by 8 to get 96
that is the total amount of seats including the broken ones. then multiply 3 by 4 to get the section of broken seats. 3 being the amount of rows that have broken seats an 4 is the amount of broken seats per row. you wind up with 12 broken seats.
Now subtract 12 from 96 to get 84 functional seats

<em>A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn. What is the probability of selecting a purple marble and then a white marble?</em>
Total outcome = 2 + 7 = 9marbles
Pr(picking purple) = number of purple/total outcome
Pr(picking red) = 7/9
Since the first marble is not replaced, the total outcome becomes 8 marbles
Pr(picking white) = 2/8 = 1/4
Probability of selecting a purple marble and then a white marble = 7/9 * 1/4 = 7/36

Answer:
24.2
Step-by-step explanation:
You are given the hypotenuse and angle, and you want to find the length of the adjacent side.
The mnemonic SOH CAH TOA reminds you that the relation between angle and sides is ...
Cos = Adjacent/Hypotenuse
cos(41°) = x/32
x = 32·cos(41°)
x ≈ 24.2
