After reading a book foe English class, 100 students were asked whether or not they enjoyed it. Nine twenty-fifths of the class
Katena32 [7]

Answer:

The number of students who liked the book was 64.

Step-by-step explanation:

After reading a book for English class, 100 students were asked whether or not they enjoyed it.

Now, given that nine twenty-fifths of the class did not like the book.

So, \frac{9}{25} of the whole class did not like the book.

Then, the fraction of the class who did like the book was (1 - \frac{9}{25}) = \frac{16}{25}.

Therefore, the number of students who liked the book was (100 \times \frac{16}{25}) = 64. (Answer)

I don't know how to do this. Any help?
Brut [27]

Answer:

cos 37=x/b (second one)

sin 37= a/b (third one)

tan 37=a/x (sixth one)

Step-by-step explanation:

Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.
