Answer:

  E.  The new volume is 27 times the old volume

Step-by-step explanation:

If L, W, and H are the original length, width, and height, then the original volume is ...

  V = LWH

The volume after the scale factor is applied is ...

  V' = L'W'H' = (3L)(3W)(3H) = 27LWH = 27V

The new volume is 27 times the old volume.

Find the sum of the geometric series for which a = 160, r = 0.5, and n = 6.
harina [27]

\\ \sf\longmapsto S_n=\dfrac{a(1-r^n)}{1-r}

\\ \sf\longmapsto S_n=\dfrac{160(1-0.5^6)}{1-0.5}

\\ \sf\longmapsto S_n=\dfrac{160(1-0.015625)}{0.5}

\\ \sf\longmapsto S_n=\dfrac{160(0.984378)}{0.5}

\\ \sf\longmapsto S_n=80(0.984378)

\\ \sf\longmapsto S_n=78.75
