If I initially have a gas at a pressure of 13.5 atm, a volume of 2300 mL, and a temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas? Report the answer in correct number of significant figures an...

for the first one perhaps say what chocolate is made from....even include from what country the cacao beans come from

math please help
A (4,3) B (3,-3) c (-4,5) Find the slope of AB, BC, and AC. Find the tangent of each angle and their angle measure (inv. tan) using: tan of an angle =m2-m1/1+m1m2 m2 being the slope of the terminal side (measuring counterclockwise) the triangle looks like this c a b

did you not understand my answer before?

Physics-Please help
did you make sure to put parentheses around the second part after the division sign?

math
A (4,3) B (3,-3) c (-4,5) Find the slope of AB, BC, and AC. Fond the tangent of each angle and their angle measure using: tanX=m2-m1/1+m1m2 m2 being the slope of the terminal side (measuring counterclockwise)

Algebra
you need to get it into slope intercept form--y=mx+b (m being the slope) to figure out whether they are parallel (having equal slopes) or perpendicular (slopes are negative reciprocals) 2y-x=2 2y=x+2 y=1/2x+1 slope=1/2 y+2x=4 y=-2x+4 slope=-2 -2 and 1/2 are negative reciprocal...

find a common denominator-x 8x/x -5/x= 2x/x +3/x when you multiply both sides by x you get: 8x-5=2x+3 8x=2x+8 6x=8 x=8/6 x=1 and 1\3

algebra
if it is 3/(x-5)=10/(x+2) then the answer is 8 cross multiply= 3x+6=10X-50 56=7x x=8

algebra
is it 3/(x-5) or 3/x -5?

trigonometry
thanks a bunch!

trigonometry
using the law of sines, solve the rest of the triangle: side C=14 side B=4 angle c=145 degrees i got angle b= 9.4 angle a=25.6 side A=10.4 but i didn't know if it was correct
