Brianna is getting materials for a chemistry experiment her teacher gives her a container that has 0.15 l of liquid in it breonna needs to use 0.4 of this liquid for the experiment how much liquid will breonna use

0.06 L

Step-by-step explanation:

Given:

0.15 L represents the 100% of the liquid. 0.4 represents the 40% of the liquid (0.4*100 = 40%). So the following proportion applies:

(0.15 L)/(100) = x/40

x = (0.15 L)/(100)*40

x = 0.15*0.4

x = 0.06 L

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
