Answer:

x>5

Step-by-step explanation:

-2(3x+2)>-8x+6 do the () first

-6x-4>-8x+6 add 8x to both sides

2x-4>6  add 4 to both sides

2x>10 divide by 2

x>5

The volumes of two spheres are in a ratio of 1:8 what is the eatio rafi
Agata [3.3K]
Remark
I take it that you want to know the ratio of the radii. If this is not correct, leave a comment below my answer.

You could do this by giving the spheres a definite volume, like 1 and 8 and then solve for r for one of them and then use the other sphere to find it's radius. It is not exactly the best way, and if you are going to to a physics class you want to be doing this using cancellation. 

Step One 
Set up the Ratio for the volumes.

\frac{V_1}{V_2} =  \frac{1}{8}

Step Two
Setup the equation for V1/V2 using the definition for a sphere. V = 4/3 pi r^3

\dfrac{1}{8} =  \frac{ \frac{4}{3} \pi( r_1)^3 }{ \frac{4}{3} \pi( r_2)^3 }

Step Three
Cancel the 4/3 and pi on the top and bottom of the fractions on the right.

You are left with 1/8 = (r1)^3/ (r2)^3

Step Four
Take the cube root of both sides.
cube root 1/8 = 1/2

Cube root of (r1)^3 = r1
Cube root of (r2)^3 = r2

Step  Five
Answer
\frac{r_1}{r_2} =  \frac{1}{2}   Answer <<<<<<<

Michel is building an in-ground swimming pool. it has a length of 16 feet, a width of 10 feet, and a depth of 8 feet. How many c
jonny [76]
The swimming pool is a <span>rectangular prism</span> (which means it's a 3D rectangle). To find the volume of a rectangular prism you multiply Length x Width x Height.

In this case that would mean 16*10*8 (height and depth are the same in this problem).

16*10*8=<span>1280 ft</span>³<span>
</span>
