Answer:

z ≥ 3

Step-by-step explanation:

When you divide by the negative coefficient of z, you reverse the inequality symbol:

-8z ≤ -24

z ≥ -24/-8 . . . . divide by -8

z ≥ 3

This graphs as a solid dot at 3, with the line extending to the right (to greater values).

The ratio of the volume of two cubes is 216 to 64. What is the ratio of their surface/

Elan Coil [88]

The volume of a cube is V=s^3, so s=V^(1/3).

The area of a cube is A=6s^2, using s found above we have:

A=6(V^(2/3))

Let V and S be the volume and area of the larger and v and s be the volume and area of the smaller cube.

A:a

6(V^(2/3)):6(v^(2/3))

V^(2/3):v^(2/3), we are given that V=216 and v=64 so

216^(2/3):64^(2/3)
