Answer:
Step-by-step explanation:
760·0.5^(t/9) = 19
0.5^(t/9) = 19/760
2^(-t/9) = 0.025
-t/9 = log₂(0.025)
t = -9log₂(0.025) = 47.9 minutes
Answer:
z=12
Step-by-step explanation:
subtract both sides by 4:
-z/3=-4
then multiply both sides by -3:
z=12
Solve for t. Simply sense its +1, do the opposite and minus 1 from both sides of the equation. +1 - 1 = 0; -3 -1 = -4. Therefore, t = -4 is the correct solution.
Here is the solution for the given problem above.
Given: 1 2/5 hour = time it takes to download a movie
5 1/4 hours = total hours for the download
? = number of movies downloaded
First, we need to simplify 1 and 2/5 hour, which is 1.4 hour, and 5 1/4 is 5.25 hours. Next, to get the number of movies downloaded, we divide 5.25 by 1.4 and the result is 3.75. Round this off to a whole number and we get 4. Approximately, you were able to download 4 MOVIES. Hope this helps.
