Answer:

Step-by-step explanation:

I would not use her suggestion because you don't know what 5 you get if you win 5 or 6. I would change it only by seeing what you would get if you score 5 or 6.

Doreen Schmidt is a chemist. She needs to prepare 28 ounces of a 8% hydrochloric acid solution. Find the amount of 14% solution
scZoUnD [109]

Let, amount of 14% solution required is x ounces.

So, amount of 8% solution will be ( 28 - x ) ounces.

Now, mathematical equation is :

\dfrac{14x}{100}+\dfrac{7(28-x)}{100}= \dfrac{8\times 28}{100}\\\\14x + 196  - 7x = 224\\\\7x = 28\\\\x = 4\ ounces

Therefore, amount of 14% solution and 8% solution required is 4 ounces and 24 ounces respectively.

Hence, this is the required solution.

3x + 4y = 2<br> 2x + 4y =8
BabaBlast [244]
We see that both equations have 4y in them. Subtracting the second equation from the first equation, we get (3x -2x) + (4y-4y) = 2 - 8, x = -6


Plugging x = -6 into any equation, we see that our answer is 18 + 4y = 2, 4y = 2 - 18 = -16, y = -4.

Our answer is x = -6, y = -4

Simplify this equation please
Maslowich

Answer:

\boxed{2\cos^2\theta}

Step-by-step explanation:

\cot^2\theta \sin^2\theta+\cos^2\theta

\dfrac{1}{\tan^2 \theta} \sin^2\theta+\cos^2\theta

\dfrac{1}{\dfrac{\sin^2\theta}{\cos^2\theta} } \sin^2\theta+\cos^2\theta

\dfrac{\cos^2\theta}{\sin^2\theta } \sin^2\theta+\cos^2\theta

\cos^2\theta+\cos^2\theta

2\cos^2\theta
