Can someone please help me with these question? Thanks! Darius makes a shirt for $8. He sells the shirt for $18. By what percentage did Darius increase the cost of the shirt?

225%

Step-by-step explanation:

18/8=2.25 and that as a percentage is 225%

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

the answer is (-4,-4)

hope this ! : d
