Answer:
Yes, they vary directly
Step-by-step explanation:
y=kx; k is the constant (12 in this case) and as x increases y increases, so they vary directly

3L is the largest quanity, 2750mL is 2nd largest, and 2.25L is the smallest. hope that helps
66,000*0.15
9,900*5
49,500+66000
The answer is 115.500
I'm not sure if the whole thing is correct, but here is the easier way:
66,000(1+1.15)^5
Answer:
A
Step-by-step explanation:
We are given that:
![\tan(\theta)=1.3](https://tex.z-dn.net/?f=%5Ctan%28%5Ctheta%29%3D1.3)
And we want to find:
![\cot(90^\circ -\theta)](https://tex.z-dn.net/?f=%5Ccot%2890%5E%5Ccirc%20-%5Ctheta%29)
Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:
![\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)](https://tex.z-dn.net/?f=%5Ctan%28%5Ctheta%29%3D%5Ccot%2890%5E%5Ccirc-%5Ctheta%29%5Ctext%7B%20and%20%7D%20%5Ccot%2890%5E%5Ccirc-%5Ctheta%29%3D%5Ctan%28%5Ctheta%29)
Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.
Our answer is A.
