Answer:

x = 25.7

Step-by-step explanation:

We know the adjacent side to the angle and the hypotenuse on a right triangle

cos theta = adj / hyp

cos 18 = x/27

27 cos 18 =x

25.67852594=x

Rounding to the nearest tenth

suppose the number of fiction books is 2/7 times the number of nonfiction books. what would be the ratio of the numbers of nonfi

Elis [28]

Well, the total amount of books is all fiction books and nonfiction books, let's say is "x", total

now, the fiction books are 2:7 or 2/7 to nonfiction

so, if we divide the total "x" by 2+7, or 9, 2 of those quotients go to fiction and 7 of those go to nonfiction

if we divide "x" by 9, a "whole" is 9/9 or (9/9)x or 1x or just "x"

and we know 7 of those 9ths belong to nonfiction, thus

$\bf \begin{array}{clclclll}
\cfrac{2}{9}&+&\cfrac{7}{9}&=&\cfrac{9}{9}\\
\uparrow &&\uparrow &&\uparrow \\
fiction&&nonfiction&&whole
\end{array}\\\\
-----------------------------\\\\
\cfrac{nonfiction}{whole}\implies \cfrac{7}{9}\implies 7:9\impliedby ratio$
