For a project, you need to make three triangles out of cardboard. Each triangle has a height of 5 inches and a base of 10 inches

Softa [21]

First, we'll need the area of a single triangle
then we'll multiply that by 3 to get our answer

to find the are of a triangle, we multiply height times base then divide that by 2
so.. 5 x 10 = 50; 50/2 = 25
if 25 = one triangle
then 25 x 3 = 75 = three triangles

answer - 75 sq. in.

What is the midpoint coordinates of segment HX H(13,8) X(-6,-6)

Setler79 [48]

Midpoint of (x1,y1) and (x2,y2) is

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

so the midpoint of HX is the mdpoint of (13,8) and (-6,-6)
which is

$(\frac{13-6}{2},\frac{8-6}{2}=$
$(\frac{7}{2},\frac{2}{2}=$
$(3.5,1)$

the midpoint is (3.5,1)
