Answer:
B. f(x) = 7000x + 4000
Step-by-step explanation:
To find the best function for this situation, we need to list down all the things that we know first.
We currently have:
35000 total seats
4000 fans
11000 fans after an hour
So that means that after an hour, we had:
11000 fans - 4000 fans = 7000 fans
At one o'clock we had 7000 more fans arrive.
So we can assume that:
x = number of hours
f(x) = 7000x + 4000 will be the best function to use to find out if there that 90% of the stadium will be filled by game time.
To test this function let's use it:
f(1) = 7000(1) + 4000
f(1) = 11000
This is after hour 1.
Now let's see after hour 4 since the game starts at 4.
f(4) = 7000(4) + 4000
f(4) = 28000 + 4000
f(4) = 32000
So 90% of 35000 is:
35000 x 0.90 = 31500
By game time we have 32000 fans which is above 90% of the total number of seats.
So the stadium owners estimate is correct.
What is the question so I can help there no tiles showe
The rectangle is 4 x 5. Area of 20.
The three triangles that are cut off from the rectangle to make QRS have areas of 5, 2, and 6. 13 total cut off.
Subtract 13 from 20.
20 - 13 = 7.
The answer is A, 7. Hope this helps!
