Una alberca tiene capacidad para 3000 litros de agua, si sólo se encuentra a tres cuartas partes de su capacidad. ¿Cuántos litros tiene

20. How many milliliters of Burow's solution (containing \( 5 \% \mathrm{w} / \mathrm{v} \) of aluminum acetate) should be used in preparing 2 liters of a \( 1: 800(\mathrm{w} / \mathrm{v}) \) solution to be used as a wet dressing?

\( \begin{array}{ll}\text { a) } \frac{1}{2} \sqrt{2}+\frac{3}{4} \sqrt{3}-\frac{1}{5} \sqrt{2} & \text { b) } \frac{3}{5} \sqrt{3}+\frac{1}{2} \sqrt{5}-3 \sqrt{3} \\ \begin{array}{ll}\text { c) } \frac{4}{3} \sqrt{5}+8 \sqrt{3}-\frac{1}{2} \sqrt{5} & \text { d) } \frac{3}{5} \sqrt{7}-\frac{1}{10} \sqrt{2}+\frac{7}{2} \sqrt{7} \\ \text { e) } 4 \sqrt{2}+\sqrt{32} & \text { f) } 3 \sqrt{2}-\sqrt{8}-5 \sqrt{2} \\ \text { g) }-\sqrt{12}+\sqrt{16}+2 \sqrt{3} & \text { h) } 2+3 \sqrt{5}-4 \sqrt{5}+(-15)\end{array}\end{array} \)

Find the slope of the line that passes through the given points. \( (-3,1) \) and \( (4,-2) \) Select the correct choice below and, if necessary, fill in the answer box within your choice. A. The slope is \( \square \). (Type an integer or a simplified fraction.) B. The slope is undefined.

\( \left. \begin{array} { l } { A B = A C , m ( \angle D ) = 50 } \\ { M ( \angle B A D ) = 20 } \\ { \sin I m ( \angle A B C ) , ( B A C ) C } \end{array} \right. \)

b) \( x^{2}-9 x+20 \) d) \( x^{2} 5 x-6 \) f) \( x^{2}-43 x-30 \)
