There are a total of 10 marbles. Out of those 2 are yellow.
So, the probability of picking a yellow marble is 2/10, or 1/5 simplified.
As a percentage, this is 20%
Hope this helps :)
U have to use Pythagoras theorem to solve this.. (adjacent)^2+(opposite)^2=hypotenuse^2
looking at the question,
the hypotenuse =15ft
opposite =12ft
adjacent =???
adjacent^2+(12)^2=15^2
a^2+144=225
group like terms
a^2=225-144
a^2=81
introduce square root to both side
root a^2=root81
a=9ft
therefore, the answer is 9ft.
I uploaded the answer to a file hosting. Here's link:
