Answer:
You have 1/60 of the original hair color left
Step-by-step explanation:
Add up the fractions
1/3 + 1/4 + 2/5
Get a common denominator of 60
1/3 * 20/20 + 1/4 * 15/15 + 2/5 * 12/12
20/60 + 15/60 + 24/60
59/60
The total is 1 or 60/60
60/60 - 59/60
1/60
You have 1/60 of the original hair color left
Answer:
sqrt(10) *x
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
x^2 + (3x)^2 = hypotenuse ^2
x^2 + 9x^2 = hypotenuse ^2
10x^2 = hypotenuse ^2
Take the square root of each side
sqrt( 10x^2) = sqrt(hypotenuse ^2)
sqrt(10) * x = hypotenuse
