The hypotenuse of a 45 45 90 triangle measures 24 inches. what is the length of one leg of the triangle?

frosja888 [35]

Answer:

$12\sqrt{2}\ in$

Step-by-step explanation:

we know that

A $45\°-45\°-90\°$ right triangle has two equal legs

Let

x-----> the length side of the leg of the triangle

y------> the length side of the hypotenuse

$sin(45\°)=cos(45\°)=\frac{\sqrt{2}}{2}$

$cos(45\°)=\frac{x}{y}$

so

$\frac{x}{y}=\frac{\sqrt{2}}{2}$

in this problem we have

$y=24\ in$

substitute the value of y and solve for x

$\frac{x}{24}=\frac{\sqrt{2}}{2}$

$x=24\frac{\sqrt{2}}{2}$

$x=12\sqrt{2}\ in$

(−3.5x+7)−(5.3x−4) plz help

mojhsa [17]

First you need to distribute the negative to 5,3x and -4 now you have this:
-3.5x+7-5.3x +4 rearrange and combine like terms (matching x's with x's etc.)
-3,5x -5.3x +7+4
-8.8x +11 your final answer there are no more like terms that you can combine.

Find the equation of a line that goes through the points (-3,5) and (5,-11)

Rasek [7]

$(\stackrel{x_1}{-3}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-11}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-11}-\stackrel{y1}{5}}}{\underset{run} {\underset{x_2}{5}-\underset{x_1}{(-3)}}}\implies \cfrac{-16}{5+3}\implies \cfrac{-16}{8}\implies -2$

$\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{5}=\stackrel{m}{-2}(x-\stackrel{x_1}{(-3)}) \\\\\\ y-5-2(x+3)\implies y-5=-2x-6\implies y=-2x-1$

Jenny makes food for her hummingbird feeders. The food is made up of 1 part sugar and 4 parts water. She uses 3434 cup of sugar

Bond [772]

Okay so every part of sugar requires 4 parts of water

so

3434 cups of sugar x 4 (parts of water per 1 part of sugar) = 13736

She will need to use 13, 736 parts of water for 3, 434 parts of sugar
