Answer: She's wrong.
Step-by-step explanation:
Numbers of hours used in solving homework last week = 15
Numbers of hours used in solving homework this week = 18

= 3/15 × 100
= 1/5 × 100
= 20%
Since Maxie said that she spent 120% more time doing homework this week, she's wrong. She only spent 20% more.

Answer:
Dynamic equilibrium
Step-by-step explanation:
Dynamic equilibrium in the human body is achieved when there is an internal control which tends to oppose certain outside forces which could affect the body. It's known to be the ability to detect and respond to stimuli by living organisms. When these stimuli occur, there are feedbacks or responses that are sent or received by the body to maintain stability. This dynamic equilibrium of the internal environment can also be seen as homeostasis.
