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 distance d from port c to port a from the given ship movement is gotten as; 7.7 miles.
<h3>How to calculate bearing distance? </h3>
We are given;
Ferry travels east 3.5 miles from Port b.
Then it turns 75° south and travels for 6 miles till it gets to Port c
To get the distance d from port c to port a, we would make use of cosine rule which is;
c = √(a² + b² - 2ab*cos C)
Thus;
d = √(3.5² + 6² - 2(3.5 * 6)*cos 75))
d = 7.7 miles

Answer:
Hes already 90, add that to the additional weight he has gain over unknown months (3.5m)
90 + 3.5m = 132
So answer is B
Answer:
2 : 3
Step-by-step explanation:
Women are = 3/5
So, Men Must be = 2/5
Ratio of Men to Women:
=> 2/5 : 3/5
Multiplying both sides by 5
=> 2 : 3
