Answer:
Im not sure what you want it to be rounded but heres the answers:
Whole number: 98
Tenths: 98.5
Hundredths: 98.49
Thousandths: 98.489
Step-by-step explanation:
This is an example of an exponential growth problem.
The formula for this is : y = x(1+r)^t
y = final amount
x = starting amount = 36
r = rate = 8% = 0.08
t = time = 11 days
y = 36(1+0.08)^11
y = 36 (1.08)^11
y = 36*2.3316389
y = 83.94 = 84 people

Answer: 9a²b
<u>Step-by-step explanation:</u>
The Pyth. Thm. tells us the following: (hypo)^2 = (leg 1)^2 + (leg 2)^2.
Here the hypo is 75 miles. One train traveled x miles and the other x+10 miles.
applying the Pyth. Thm.,
x^2 + (x+10)^2 = 75^2
which becomes x^2 + x^2 + 20x + 400 = 5625, or
2x^2 + 20x - 5225 = 0.
Choose a method easy for you that will lead to a solution (x-value).
Using "completing the square," I obtained x= 47.8 miles and x = 57.8 miles. I
It's very important to check one's work. Suppose x = 47.8 miles. Then x+10 = 57.8 miles.
47.8^2 + 57.8^2 = 75^ must be true. Is it?
2284.84 + 3340.84 5625
5625.6 is approx equal to 5625. Close enough.
The first train traveled 47.8 miles and the second 57.8 miles.
