Answer:

Step-by-step explanation:
The formula of a surface area of a sphere:

R - radius
We have

Substitute and solve for R:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>

The formula of a volume of a sphere:

Substitute:

Answer:
x: (3,0)
y: (0,-10)
Step-by-step explanation:
x intercept is where the line crosses the x axis
y intercept is where the line crosses the y axis
Answer:

Step-by-step explanation:
let x be the numerator of the rational number then 2x is the denominator
original fraction = 
subtracting 3 from numerator and adding 7 to denominator , gives
=
( cross- multiply )
5(x - 3) = 2(2x + 7) ← distribute parenthesis on both sides )
5x - 15 = 4x + 14 ( subtract 4x from both sides )
x - 15 = 14 ( add 15 to both sides )
x = 29
rational number =
