In str, h is the centroid, eh = 6,dh = 4, and sm = 24.
find each measure.

  7. 16

  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

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
