Answer:
See below
Step-by-step explanation:
the common ratio, r <1 so it CONVERGES (r = 1/2 in this series)
sum = a1 ( 1-r^n) / (1-r) = 1000(1-.5^10)/(1-1/2) = ~1998
for n= 30 this results in ~~2000
As it continues, the terms get smaller and smaller and the SUM converges on 2000.
2/3= 0.6667 which you can figure out by 2÷3
3/4= 0.75 which you can figure out by 3÷4
because 0.75 is greater than 0.6667 she has enough to make the cake.
Answer:
so you divide 16x÷2xy=8/y
which also same as 8y-¹
