Hi there!

Let's solve this inequality step by step!
- 6r + 2r > 3 - 3r

First collect the terms on the left.
- 4r > 3 - 3r

In order to solve, we must isolate r. Therefore we need to bring them all to the left. Our next step will therefore be to add 3r to both sides of the equation.
- r > 3

Finally we need to divide both sides of the equation by -1. Because we divide by a negative, the sign flips.
r <  - 3

Hence, the answer is r < -3.
~ Hope this helps you!

Compare the surface area-to-volume ratios of the moon and mars. express your answer using two significant figures.
antoniya [11.8K]

we know that

For a spherical planet of radius r, the volume V and the surface area SA is equal to

V=\frac{4}{3} *\pi *r^{3} \\ \\ SA=4*\pi *r^{2}

The
ratio of these two quantities may be written as

SAV =\frac{(4*\pi*r^{2})}{(\frac{4}{3}*\pi*r^{3})}     \\  \\ SAV =\frac{3}{r}

we know

rMoon=1,738Km\\ rMars=3,397 Km

\frac{SAV Moon}{SAV Mars} =\frac{3}{rMoon} *\frac{rMars}{3} \\ \\ \frac{SAV Moon}{SAV Mars} =\frac{rMars}{rMoon} \\ \\ \frac{SAV Moon}{SAV Mars} =\frac{3,397}{1,738} \\ \\ \frac{SAV Moon}{SAV Mars} =1.9545

therefore

the answer is

1.9
