Answer:
10·2^-8 grams
Step-by-step explanation:
The each day, the initial amount for that day is multiplied by 1/2. After 8 days, the initial amount has been multiplied by (1/2)^8, where the exponent of 8 signifies that (1/2) is a factor 8 times in the product.
After n days, the quantity remaining is ...
q(n) = 10·(1/2)^n = 10·2^(-n)
after 8 days the remaining amount is ...
q(8) = 10·2^-8 . . . grams
Answer:
Step-by-step explenation . First you know that the amount of time she trained for the marathon is 125% of the time she trained last month. We also know that she trained 80 hours last month. And the question wants us to know how many hours she trained this month. So we do 100% =x
And 125% = 80 so we cross multiply it becomes 100 X 80 =125x witch eaquals to 8,000 divided by 125 witch is 64. So the final Answer is 64 . IF I AM CORRECT PLEASE MARK BRAINLIEST.
