A≈8
V Volume
Using the formula
V=a3
Solving fora
a=V⅓=512⅓≈8
Therefore, to find the lenght of an edge of the cube, just find the cube root of the volume. In this case, the cube root of 512 is equal to 8.
Um I think the first one is non proportional and the 2nd one is proportional y is 5 times x the 5 might be a negative
Answer:
Step-by-step explanation:
A question on a math quiz asks, "What is 175% of 72?" Petra calculates 12.6 as the answer. Is this a reasonable answer? Explain
No because the scale factor is inconsistent while it would be neccecary to be consistent if it was similar. 19.9/15.3=1.3 while 29/25=1.16 which proves that they have an inconsistent scale factor.
I'm not sure how to answer the question... BUT, I know that the side that says 2 is for the blue marbles and 1 is for the red marbles, meaning that every 2 blue marbles she has equal 1 red marble.
Sorry I didn't have the answer, hope this helps :/
