We are told that every 9th person gets free popcorn and every 6th person gets free apple juice at the movie theater. We want to show if the 36th person is the first to get both free popcorn and apple juice.
Since every 9th gets free popcorn, then the 9th and 18th and 27th and 36th people get it. We can use numbers and show this as multiples of 9.
9, 18, 27, 36, 45, 54, ...
And we repeat it for every 6th and the free juice.
6, 12, 18, 24, 30, 36,....
Shani thinks 36 comes first, and she's wrong. 18 appears on the list before 36 as something that's common. What are we finding is the lowest common muliple of 6 and 9.
6 = 2 x 3
9 = 3 x 3
The lowest common multiple will have a 2, a 3, and a second 3 (because we don't double count). 2 x 3 x 3 = 18. This matches up to the list of multiples.
Thus, Shani is wrong that the 36th person gets both free items, as she did not account for the 18th person gettting both free items
Answer:
A. F(x) = x^3+9x^2+27x+27
Step-by-step explanation:
I am not 100% sure but I think this is right.
I found the root for this equation: x=-3
Hope this helps!
His location would be 20 feet above the sea level because...
30+-10= 20 because adding a negative to a positive is basically like subtracting.
Can have a brainliest answer now please?
I don't like algebra pretending to be geometry. These are supplementary angles, adding to 180 degrees, geometry done.
We'll assume the units on the 2 and 8 are degrees.
(x + 8) + (3x + 2) = 180
4x + 10 = 180
4x = 170
x = 170/4 = 85/2 = 42.5 degrees
The first angle is x+8 = 50.5 degrees
The second angle is 3x+2=129.5 degrees
