Step-by-step explanation:

Right triangle

cosine 60 =adjacent leg / hypotenuse

      cosine 60 = x / 22      x = 22 cos 60 = 11

sine 60 = opposite side / hypotenuse = y/22

22 sin 60 = y = 22 * sqrt (3) / 2 = 11 sqrt 3    or   19.05

6n + 9 = -3 - 21 - 6
denis23 [38]
6n+9=-3-21-6
subtract the numbers:-3-21-6=-30
6n+9=-30
subtract 9 from both sides
6n+9-9=-30-9
simplify
6n=-39
divide both sides by 6
\frac{6n}{6}= \frac{-39}{6}
n= \frac{-13}{6}
decimal n=-6.5
Hope this helps :)

The table lists the results from a survey (of questionable accuracy) of adults and how much they spend on a night out.
daser333 [38]
You are going to make a graph. The x-axis will represent age while the y-axis represents the amount of money spent on a night out. Graph the ordered pairs, making a scatter plot. Once you have all of the points on the graph, answer the question by saying something like "the older someone is, the less money they spend on a night out" but make sure it's accurate. (:
