Answer:
45,000 people
Step-by-step explanation:
Let
P -----> the number of people, that are left in the stadium
M ----> the time in minutes
we have
This is a linear equation in slope intercept form
where
The slope is
----> is negative because is a decreasing function
The P-intercept is
Remember that the P-intercept is the value of P when the value of M is equal to zero
That means
For M=0 min
P=45,000 people (number of people that were present when the game ended but before people started to leave)
Answer:
1: 3/4 = 6/8 = 9/12
2: 2/3 = 4/6 = 6/9
3: 8/9 = 16/18 = 24/27
Step-by-step explanation:
The answer would be 17 just divided 85 by 5 and you'll get your total :)
This is like the equation of a line where y is the area, x is the time, and 8.5% is your slope. So you have y=0.085x+b (reason why I switched 8.5% into 0.085 is because that is how you write a percent as a decimal).So now you need to find what b is. So you know orignally the area is 2400km^2 at x=0 years (this is what it is initially).If you plug those numbers in you have:2400=0.085(0)+bThen after solving for b, you can write your equation as:y=0.085x+(whatever you found b to be)Then plug 13 in for x and you have your answer. y=-.085(13)+2400
