A total of 50,000 contestants participate in an internet on-line survivor game. The game randomly votes off 20% of the contestants each day. Approximately how many
contestants are left in the game at the end of five days, to the nearest contestant?

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

i believe a. 12x≥120 is the answer
