Katie needs 60 mL of a 10% acid solution for a science experiment. She has available a 8% solution and a 20% How many milliliters of the 8% solution and how many milliliters of the 20% solution should she mix to make the
solution?

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
