Answer:

10.3125 (NOT ROUNDED)

Step-by-step explanation:

1. I changed it to decimals. 1/4 can easily be changed into a decimal.

2. I set 1/4 = x/100. Then cross multiplied. That would give you 4x = 100.

3. Now you would simplify that. x would be 25. So its 25/100 wich then turns to .25.

4. Now you are going to replace them so it would be 1.25 and 8.25.

5. To find out how much milk chocolate there was you would multiply 1.25 and 8.25.

6. That's your final answer

Answer:

$\sin \: x - \cos x \: + c$

Step-by-step explanation:

$\int \frac{cos2x}{ \sqrt{1 - sin2x} } dx \\ \\ = \int \frac{ {cos}^{2}x - {sin}^{2}x } { \sqrt{ {sin}^{2}x + {cos}^{2}x - 2sinx \: cosx } } dx \\ \\ = \int \frac{ ({cos}x - {sin}x )({cos}x + {sin}x )} { \sqrt{ {({cos}x - {sin}x )}^{2} } } dx \\ \\ = \int \frac{ ({cos}x - {sin}x )({cos}x + {sin}x )} {{ {({cos}x - {sin}x )} } } dx \\ \\ = \int({cos}x + {sin}x)dx \\ \\ = \int{cos}x \: dx + \int{sin}x \: dx \\ \\ = \sin \: x - \cos x \: + c$
