A 1 = 57, a 2 = 61, a 3 = 65 ( arithmetic sequence )
a n = a 1 + ( n - 1 ) d
a 2 = a 1 + d
61 = 57 + d
d = 61 - 57
d = 4
a 9 = 57 + 8 * 4 = 57 + 36 = 93
Answer: Her score on the 9th assessment will be 93 points.
Answer:
90000

To get the total area multiply 75 by 30 then to get the number of people multiply the product by 40. 75*30*40=90000
Y=31.2
X=15.6
I rounded both to the nearest tenth place.
