$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$

x% of 25 =15

x=15/25
x=3/5

x=.6

Mulitply by 100 to get percentage

√(11)/11 is already simplified. Since √(11) is a radical, it would require a long decimal, and it would only be an approximation.

4*2=8

120/(3/4) = 4(120)/3

480/3

160

First, turn the percent into a decimal: for exemple 40% = .4
Then turn the decimal into a fraction: .4/1; 4/10.

Finally simplify: 2/5

Think of this formula V=(4/3)πr³

4.5=(4/3)πr³

13.5=4(πr³)

3.375=πr³

3.375/π=r³

∛(3.375/π)=r

A googol is a number that is equal to 1*10¹⁰⁰

If f(x)=x+5 then f ^-1(x)=x-5 because subtraction is the inverse of addition.

The circumference of is circle is equalt π times the diameter. C=dπ
