Answer:
537.47712
Step-by-step explanation:
a = 125 ... the first term?
r = 1.2
ok use the formula: a_n = (a_1) * r ^(n-1)
we want a_9 = (a_1) * r^(9-1)
a_9 = 125 * (1.2)^8 = 125 * 4.29981696 = 537.47712
Answer: C
Step-by-step explanation: simply apply the distributive property to each half of the expression to be left with terms that can be combined.
(8x + 16y)/2 = 4x + 8y
4(x - y) = 4x - 4y
(4x + 8y) + (4x - 4y) = 4x + 4x + 8y - 4y
= 8x + 4y => C
About 55.8 (i suggest rounding up to 56) are packed in 480 seconds. just divide 480 by 8.6 to get the answer 55.8
