Achemist has 200ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the chemist needs the concentration of the final mixture to be 30% how many milliliters of the 40% solution should she add to the 10% solution to get this concentration ?

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.
