I don’t know if I’m completely correct but the interior of a pentagon is 540 degrees so add all of them up. Then subtract 540- all of them added up and that should be the answer
Answer:
250 Students are musicians, 200 are not.
Step-by-step explanation:
Decimal Version:
If we take "5 out of every nine students are musicians" and make this a fraction we get 5/9. 5/9 as a decimal is approximately 55.555555555556. 55.555555555556% of 450 = 250. So that means 250 students are musicians.

Answer:
Step-by-step explanation:
In a geometric sequence, the nth term is
T_n = ar^(n-1)
a = first term
r = common ratio which can be gotten by dividing second term by first term, third term by second term etc
Therefore
a = 16
r = -3.2 ÷ 16
r = -0.2
T_7 = ar^(7-1)
T_7 = ar^6
T_7 = 16[(-0.2)^6]
T_7 = 16(0.000064)
T_7 = 0.001024
Slope m = (y2 - y1)/(x2 - x1) < (FORMULA)
= (9-3)/(7+5)
= 1/2 or 0.5
