Answer:
11.4 x 10 ^ 6
Step-by-step explanation:
- First, you have to convert 3.8 x 10^5 out of scientific notation. To do that, multiply 3.8 * 10^5, you'll get 380,000. This is the weight of each whale.
- Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
- Convert back to scientific notation. 11.4 x 10^6
