Answer:

Step-by-step explanation:

Ok. first you want to determine the size of each side. 5 x 9 = 45 gets you the rectangle. You already have the tricky part, which is getting the width of the triangle. Now what you do is add 2.5 + 2.5 + 5 for the length, then you can do simple math and say 2.5 + 2.5 + 5 = 10

10 x 3 = length x width = 30, but since it's a triangle divide it by 2 and you'd get 15.

Now all you do is add them together and you get 60

What is the value of x so that the line segment with endpoints W(x, −2) and X(5, −4) is parallel to the line segment with endpoi

coldgirl [10]

Answer:

x equals six start fraction one over two end fraction

Step-by-step explanation:

Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.

Slope of YZ is:

$m = \frac{y_2-y_1}{x_2-x_1}=\frac{2-6}{2-5}=\frac{-4}{-3}=\frac{4}{3}$

Since they are parallel, then WX has a slope of 4/3 too.

Slope of WX is:

$m = \frac{y_2-y_1}{x_2-x_1}\\\\\frac{4}{3}=\frac{-2--4}{x-5}\\\\\frac{4}{3}=\frac{2}{x-5}\\\\\frac{4}{3} (x-5) = 2\\\\4x -20=6\\\\4x = 26\\\\x = 6\frac{1}{2}$

I NEED THIS FAST a sample of an unknown liquid has a volume of 30.0 mL and a mass of 6 g. whats the density ? show your work and

Doss [256]

Answer:

The density is 0.2g/mL^2.

Step-by-step explanation:

Use the formula: D= $\frac{m}{V}$ (where v=volume, and m=mass). The mass of the liquid is 6g. The volume of the liquid is 30mL.
To determine density, insert the values into the formula ( $D=\frac{6g}{30mL}$ ).
Divide: 6g/30mL= 0.2g/mL^2
