Question

Mark studied a group of 30 whales. If each will wait approximately 3.8×10 to the fifth power, pounds find the total weight of all 30 whales express your answer in scientific notation

Answer 1

11.4 x 10 ^ 6

Explanation:

1. 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.
2. Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
3. Convert back to scientific notation. 11.4 x 10^6
