Answer:
5/6
Step-by-step explanation:
The ratio is:
45 / 54
Or, reduced:
5 / 6
Answer:
assuming it is a circular cylinder it would be A
Step-by-step explanation:
I think its B. Because 396 divided by 3 equals 132 (there's 3 feet in a yard)
The equation of the parabola in vertex form

Given :
vertex (3,2), point (2,-4)
The vertex form of parabola is 
Where (h,k) is the vertex
Given vertex is (3,2). so, h=3 and k=2
Replace it in the equation

Now we find out the value of 'a' using the given point (2,-4)
Point (2,-4) is (x,y)
x=-2 and y=-4
Replace it in the equation we got to find out 'a'

Step-by-step explanation:</h3>
<u>Step 1: Define</u>
[RxN] 2NO₂ ⇆ N₂O₄
[Equilibrium Rate Law] ![\displaystyle K_c = \frac{[N_2O_4]}{[NO_2]^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20K_c%20%3D%20%5Cfrac%7B%5BN_2O_4%5D%7D%7B%5BNO_2%5D%5E2%7D)
NO₂ = 11.95 M
N₂O₄ = 6.05 M
<u>Step 2: Find K</u>
- Substitute [ERL]:
![\displaystyle K_c = \frac{[6.05]}{[11.95]^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20K_c%20%3D%20%5Cfrac%7B%5B6.05%5D%7D%7B%5B11.95%5D%5E2%7D)
- Exponents:
![\displaystyle K_c = \frac{[6.05]}{[142.803]}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20K_c%20%3D%20%5Cfrac%7B%5B6.05%5D%7D%7B%5B142.803%5D%7D)
- Divide:

- Round (Sig Figs):

This value of K tells us that the reactants are favored in the equilibrium reaction (K < 0.1).
