Answer:

7. 16

8. 8

9. 8

10. 12

11. 12

12. 18

Step-by-step explanation:

The centroid cuts each median into parts in the ratio 2:1. This fact can be used to find the desired lengths.

7. SH = 2/3×SM = 2/3×24 = 16

8. HM = 1/3×SM = 1/3×24 = 8

9. TH = 2×DH = 2×4 = 8

10. HR = 2×EH = 2×6 = 12

11. TD = TH +DH = 8 +4 = 12

12. ER = EH +HR = 6 +12 = 18

Which of the following expressions could be used to find the perimeter of this figure?

Burka [1]

Answer:

Step-by-step explanation:

four of the sides are equal to 18mm, so that would be the 4(18mm), and then the two other sides are equal to 24mm, which is 2(24mm). Your full equation would be:

P= 4(18mm) + 2(24mm)

what is the slope-intercept form for a line that has a slope of -4/5 and passes through points (0,7)?

drek231 [11]

$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{7})~\hspace{10em} slope = m\implies -\cfrac{4}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-7=-\cfrac{4}{5}(x-0) \\\\\\ y-7=-\cfrac{4}{5}x\implies y=-\cfrac{4}{5}x+7$
