Jane is building eight 3-legged stools. Each leg is 1/2 yard long. She can cut the legs from wooden rods that are sold in 2-yard

jonny [76]

Answer:

$n = 6\,rods$

Step-by-step explanation:

The total of legs needed to build the stools are:

$x = (8) \cdot (3)$

$x = 24$

Likewise the total length of the legs is:

$L_{tot} = 24\cdot (0.5\,yd)$

$L_{tot} = 12\,yd$

Lastly, the quantity of rods that needed to buy is:

$n = \frac{12\,yd}{2\,\frac{yd}{rod} }$

$n = 6\,rods$

Van purchased a DVD player on sale. The original selling price was $175.80. The sale price was $149.42. What is the first ste

rjkz [21]

Answer:

The percent decrease was 15%

Step-by-step explanation:

In order to find this, use the percent change equation.

(New - Old)/(Old) * 100 = % Change

Now input 149.42 for the New price and 175.80 for the Old price.

(149.42 - 175.80)/(175.80) * 100 = % Change

-26.38/175.80 * 100 = % Change

-.15 * 100 = % Change

-15 = % Change

Will Mark The Brainliest. Write an equation of the line graphed in slope-intercept form using the variables x and y.

baherus [9]

Answer:

$\boxed{y=-2x+5}$

Step-by-step explanation:

The equation in slope-intercept form is given by:

$y=mx+c$

where $m$ is the slope and $c$ is the y-intercept.

The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through $(x_1,y_1)= (1,3)$ and $(x_2,y_2)=(2,1)$ .

The slope is given by;

$m=\frac{y_2-y_1}{x_2-x_1}$ .

$\Rightarrow m=\frac{1-3}{2-1}$ .

$\Rightarrow m=\frac{-2}{1}=-2$ .

The y-intercept from the graph is $c=5$

Our equation finally becomes;

$y=-2x+5$
