Answer 8

You just need to find the ratio between 16 to 1458.

Recall that,
a to b is the same thing as a:b or a/b

Answer 9

So 16:1458, what do I do next?

Answer 10

You need to simplify it. Can you find any common factors between 16 and 1458?

Answer 11

8/729

Answer 12

That's correct! They both had a factor of 2. And there are no other factors because 8 = 2^3 and 729 = 9^3

Answer 13

Okie, thanks

Answer 14

My pleasure!

Answer 15

Answer was wrong, somehow

Answer 16

What was given as the correct answer?

Answer 17

@Vocaloid Can you confirm?

Answer 18

It doesn't say, it just says that D was incorrect

Answer 19

1458 * 8/729 = 16

And the units are the same for both.
Mhmm

Answer 20

you have to be careful with scale factors

for volume, increasing by scale factor x results in a volume increase of x^3

so it's actually the cube root of (8/729)

Answer 21

Thats what I put in and it was marked as incorrect, see? http://prntscr.com/i88i5o

Answer 22

Duh, totally slipped my mind.

Yes, Vocaloid is correct.

Answer 23

it needs to be the cube root of 8/729 not just 8/729

Answer 24

(8/729)^(1/3) --> simplify and you'll get your answer

Answer 25

So then it was B? 2/27?

Answer 26

cube roof of 729 = ?

Answer 27

*root

Answer 28

27

Answer 29

Ohhhh

Answer 30

the cube root of 729 is 9 not 27

so 2/9 = your ans

Answer 31

Oh
