I think its 2 bc two ppl sit behind each persin from the first and second row.
Answer: 18 degrees
Step-by-step explanation:
If the temperature dropped 12 degrees (48-36) in 10 hours then the ratio is
10hours:12 degrees
to find hours divide both sides by 2 and multiply by 3 to get
15hours: 18 degrees

Step-by-step explanation:
dont need to graph the center dot, its just the origin
Answer:
<h3> 1/√3</h3>
Step-by-step explanation:
Given the expression tan (-150), from trigonometry identity, tan(-θ) = -tanθ
Hence tan (-150) = - tan 150
First is to find the value of tan 150.
tan 150 = tan (180-30)
tan (A+B) = (tan180 - tan30)/1+tan180tan30
tan (180-30) = (0 - 1/√3)/1+0(1/√3)
tan (180-30) = -1/√3/1
tan (180-30) = -1/√3
Since tan 150 = -1/√3
-tan 150 = -(- 1/√3)
-tan 150 = 1/√3
Since -tan 150 = tan (-150) = 1/√3
Hence the exact value of tan (-150) is 1/√3
If the spinner is spun three times, there are three possibilities for each spin, so there are 3*3*3=27 possible outcomes. Note that the letters on the spinner are extraneous information (i.e. you don't need to know what the letters are to solve the problem).
