how much of a 0.225 M KCl solution contains 55.8g of KCl

math
Keep using the distance formula to find the distance between 2 of the vertices which will give you the length of that section of the "fence". Add up all the totals to get the answer. Then multiply by 10 to get the answer in Meters. Distance = square root of ( (x2-x1)...

algebra
First i added 260 and 275 because in an hour (since they took off at the same time) the planes will be 535miles apart. Now just divide 1605 by 535 and the answer is: 3 hours

Chemistry
An isotope has the same number of protons as the original element, but different number of neutrons. I think the answer is A because atomA and atomD have the same number of protons and a different number of neutrons.

math
if they are coordinates, can't you use the distance formula? the least amount would be: square root of ( (x2-x1)^2 + (y2-y1)^2 ) = 102.142 he will probably need more cable because in real life there may possibly be obstacles preventing a straight line of cable

INTRODUCTORY ALGEBRA
the only number that will give you the answer 3 is the number 0

geometry
if QR=3x and RS=x+12, then x=?
