Answer:
n>=6
Step-by-step explanation:
1-0.4ⁿ>=0.99
1-0.99>=0.4ⁿ
0.4ⁿ<=0.01
Apply log10:
Log10(0.4ⁿ)<=log10(0.01)
n×log10(0.4)<=log10(0.01)=-2
Because log10(0.4)=-0.39794 is negative we get:
n>=5.028.
Since n is integer, we have n>=6
Answer:55

Answer:
a
Step-by-step explanation:
Two points are always collinear since we can draw a distinct (one) line through them.
3 3/4 lb of candy costs $ 20.25
we have been given a mixed fraction with both whole number and fraction
so lets convert it an improper fraction
3 3/4
3 wholes are equivalent to 
then 3 3/4 is - 
so 15/4 lbs -- $ 20.25
then 1 lb is -- 
therefore 1 lb is equal to $ 5.40
