Answer:
the plant was approximately 14.06 cm tall after 3 weeks.
Explanation:
In science class the students need to measure a plant’s growth over time. The first week, the plant was 3.04 cm tall. It tripled in size the second week, and then grew another 1.9 cm the third week. How tall was the plant after 3 weeks?
After 3 weeks, the plant's height can be calculated by adding the growth from each week to the initial height of 3.04 cm.
The plant tripled in size during the second week, which means it grew to 3.04 cm * 3 = 9.12 cm .
In the third week, the plant grew an additional 1.9 cm .
To calculate the total height after 3 weeks, we add the growth from each week to the initial height:
3.04 cm + 9.12 cm + 1.9 cm = 14.06 cm.
Therefore, the plant was approximately 14.06 cm tall after 3 weeks.
