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)

How do I solve this literal equation? <br> 15 points

kati45 [8]

Answer:

$\pi = \frac{A}{2r^2 + 2rh}$

Step-by-step explanation:

First, we need to isolate $\pi$ by taking it common from both terms on the right:

$A=2\pi r^2 + 2\pi rh\\A=\pi (2r^2 + 2rh)$

Now, since we want $\pi$ in terms of the other variables, we can divide the left hand side (A) by whatever is multiplied with $\pi$ on the right hand side. Then we will have an expression for $\pi$ . Shown below:

$A=\pi (2r^2 + 2rh)\\\pi = \frac{A}{2r^2 + 2rh}$

This is the xpression for $\pi$
