Answer: Choice B) 2^(-10) and 1/1024
------------------------------------------------------
Explanation:
We'll use these two rules
Rule 1: (a^b)^c = a^(b*c)
Rule 2: a^(-b) = 1/(a^b)
Using rule 1 above, we can say
(2^5)^(-2) = 2^(5*(-2)) = 2^(-10)
So 2^(-10) is one of the answers
Now use rule 2 to convert 2^(-10) into...
2^(-10) = 1/(2^10) = 1/1024
so 1/1024 is the other answer
Answer:
a. 8/24 or 1/3 a day
b. 45/60 or 3/4 a hour
c. 1/7 of a week
d. 4/12 or 1/3 a year
Step-by-step explanation:
Simply divide by the conversion you want to set.
60 seconds is 1 hour
24 hours is 1 day
7 days is 1 week
3-4 weeks per month (depending on the month and year)
12 months a year
