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.
Answer: The answer would be 1=x
Step-by-step explanation: I got this because 8-2 equals to 6, so just multiply 2 by one and the equation is 8-2=6
Answer:263.89cm cubed
Step-by-step explanation:
Volume of A Sphere: 4/3 pi radius cubed
4cubed= 64
64 times pi=201.061
201.061 multiply 4/3= 268.08
1cubed= 1
1 times pi=3.14
3.14 times 4/3= 4.19
268.08-4.19= 263.89cm cubed
Answer:
(6, -4) does not fit with these two equations
Step-by-step explanation:
y = 8 - 2x
x + 3y = 12
fit (6, -4) into the equations
-4 = 8 - 2(6)
8 - 2(6) = 8 - 12 = -4
works for this one
6 + 3(-4) = 12
6 + 3(-4) = 6 - 12 = -6
doesnt work for this one
