-8x if I read the problem correctly
Answer:
4.048 hours
Step-by-step explanation:
A = Pe^(rt)
After 1 hour, the amount decreases by 29% (A = 0.71P), so r is:
0.71P = Pe^(r×1)
0.71 = e^r
r = ln(0.71)
r = -0.342
P = 400. When A = 100, the time t is:
100 = 400e^(-0.342 t)
0.25 = e^(-0.342 t)
ln(0.25) = -0.342 t
t = -ln(0.25) / 0.342
t ≈ 4.048
Approximately 4.048 hours have passed.
The answer is 20 because adding 10 twice is 2. And the answer is 10 times 2 so u have to add 10 twice for the product
If your friend made $20 dollars they made 2/3 of the money, and you got 1/3 of the total money then that means you made $10 dollars.
