Evan, Claire, Jaya and Tim are running a 3km relay race. Evan ran 9/10 of a km
Claire ran 7/9 of a km
Jaya ran 2/3 of a km

What fraction of a km does Tim need to run to finish the race?

Try to answer ASAP please, thank you.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
