Answer:
2/6561
Step-by-step explanation:
Geometric sequence formula : ![a_n=a_1(r)^n^-^1](https://tex.z-dn.net/?f=a_n%3Da_1%28r%29%5En%5E-%5E1)
where an = nth term, a1 = first term , r = common ratio and n = term position
given ratio : 1/3 , first term : 2 , given this we want to find the 9th term
to do so we simply plug in what we are given into the formula
recall formula : ![a_n=a_1(r)^n^-^1](https://tex.z-dn.net/?f=a_n%3Da_1%28r%29%5En%5E-%5E1)
define variables : a1 = 2 , r = 1/3 , n = 9
plug in values
a9 = 2(1/3)^(9-1)
subtract exponents
a9 = 2(1/3)^8
evaluate exponent
a9 = 2 (1/6561)
multiply 2 and 1/6561
a9 = 2/6561
Answer:
2+4x=8.5
Step-by-step explanation:
8x=13
x=13/8
x=1.625
I'm going to assume that you mean 56% of the calories come from fat. So, we would have to find out 56% of 270 which is 151.2, so now we know that 151.2 calories in the cereal come from fat!
