Answer:

It wouldn't.

Step-by-step explanation:

With the ratio, since Zeona has 36 cards, Kyle must have 54. If they each sold half, Kyle would have 27 and Zeona would have 18. So, the ratio would still be 3:2.

I kinda forgot my trig (kinda)
Ipatiy [6.2K]
\sec^2\theta=1+\tan^2\theta\implies \sec\theta=\pm\sqrt{1+\tan^2\theta}

Since \cos\theta>0 for 0, we have \sec\theta>0, so we take the positive root. Now,

\sec\theta=\sqrt{1+\left(\dfrac{12}5\right)^2}=\dfrac{13}5

- - -

\tan\theta=\dfrac{\sin\theta}{\cos\theta}
\cos^2\theta=1-\sin^2\theta

In the first quadrant, cosine is positive, so

\cos\theta=\sqrt{1-\sin^2\theta}

and in turn,

\sin\theta=\dfrac35\implies\cos\theta=\sqrt{1-\left(\dfrac35\right)^2}=\dfrac45
\implies\tan\theta=\dfrac{\frac35}{\frac45}=\dfrac34

- - -

In the previous problem, we had \cos\theta=\dfrac45, so we must have \tan\theta=\dfrac34, which means

\cot\theta=\dfrac1{\tan\theta}=\dfrac1{\frac34}=\dfrac43

Lapatulllka [165]

Answer:

y=6/5x+13

Step-by-step explanation:

6y=-5x+16

Divide by 6

y=-5/6x + 8/3

Slope: 6/5 (opposite reciprocal)

7=-5(6/5)+b

7=-6+b

b=13

Answer:

44

Step-by-step explanation:

If a serving size is 1/2 ounce, there are 2 servings (2/2) per ounce. Let's multiply this by the total ounces.

22 × 2 = 44

There are 44 servings in the bottle of ketchup.
