Solve for r<br><br>v = 4/3 r^3<br>

sergejj [24]

Answer:

$r=\sqrt[3]{\frac{3v}{4} }$

Step-by-step explanation:

To solve for $r$ :

$v=\frac{4}{3}r^{3}$ (given)

$\frac{3v}{4}=r^{3}$ (times $\frac{3}{4}$ on both sides)

$r=\sqrt[3]{\frac{3v}{4} }$

I hope this helps :)

Sales rise from £400 a week to £504 a week. Calculate the percentage increase

Andrew [12]

Answer:

26%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

Here, the new number is £504, and the old number is £400.

percent change = (£504 - £400)/(£400) * 100% =

= £104/£400 * 100% = 0.26 * 100% = 26%

Ben said the graph of the inequality

Ksivusya [100]

Answer:

Ben is incorrect

The solutions are x>-3 and x < 3

Step-by-step explanation:

we have

$-x^{2} +9 > 0$

Multiply by -1 both sides

$x^{2} -9 < 0$

Adds 9 both sides

$x^{2} < 9$

The solutions are

$x < 3$

and

$-x < 3$ -----> Multiply by -1 both sides ----> $x > -3$

therefore

The solution is the interval (-3,3)
