Answer:
yes it is
Step-by-step explanation:
The nearest tenth means 1 decimal place.
so the answer is 8.5
Answer:
Scale factor = 
Perimeter ratio = 4 : 9
Surface area ratio = 16 : 81
Volume ratio = 64 : 729
Step-by-step explanation:
Volume ratio = 
= 
=
= 64 : 729
Scale factor = ![\sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B%5Ctext%7Bvolume%20of%20small%20prism%7D%7D%7B%5Ctext%7BVolume%20of%20large%20prism%7D%7D%7D)
= ![\sqrt[3]{\frac{64}{729}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B64%7D%7B729%7D%7D)
= 
Perimeter ratio = Scale factor
= 
= 4 : 9
Surface area ratio = (Scale factor)²
= 
= 
= 16 : 81
It would be - 77/4 because 9/14-11/14=- 1/7 then you do 11/4 -/ 1/7 which equals -77/4
