At lunch your friend slips a water bottle 45 times and it lands on its base 9 of them. what was their percent of success?

20%

Step-by-step explanation:

This is a really sad problem but okay

So we are trying to find the success rate which is also known as percentage

To find a percentage we can do

part/whole = percentage/100

So the part would the 9 times the friend landed and the whole would be 45

Now, we have 3 parts of the equation and we can plug them all in to fine x (the success rate)

First you divide the part by the whole and get

9/45 = 0.2

Then you multiply this by 100 to get

A 20% sucess rate

Have a nice day ! <3

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

ou would have 12 of each
