kimi is playing hide-and-seek with Tommy and Manuel. Tommy is hiding 12 feet south of Kimi, and Manuel is hiding due east of Tom

Answer:

Tommy and Manuel are 16 ft apart

Step-by-step explanation:

The locations of all three players are shown in the image below

They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.

We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then

$c^2=a^2+b^2$

Knowing c and one of the legs, say b:

$a^2=c^2-b^2$

Using the values c=20, b=12 we find

$a^2=20^2-12^2=400-144=256$

$a=\sqrt{256}=16$

So, Tommy and Manuel are 16 ft apart

-5f-2+8-3k use f=7 and k=8

gulaghasi [49]

The answer to this equation is -53. This is because 7 times -5 equals -35. -35-2 equals -37. -3 times 8 equals -24. -24 plus 8 equals -16. -37+(-16)= -53
