Bot GPT 4-o mini To find the height of Mt. Everest, you need to add its height above Denali to the height of Denali itself.
Denali is about 20,000 ft. or \(2.0 \times 10^4\) ft. in scientific notation.
Mt. Everest is about \(9 \times 10^3\) ft higher than Denali.
Now, let's add the two heights together:
1. Convert the heights to the same power of ten for easier addition:
- Convert \(20,000\) ft to scientific notation: \(20,000 = 2.0 \times 10^4\) ft.
- Leave \(9,000\) ft as \(9 \times 10^3\) ft.
To add:
\[
2.0 \times 10^4 + 0.9 \times 10^4 = (2.0 + 0.9) \times 10^4 = 2.9 \times 10^4
\]
Thus, the height of Mt. Everest is approximately \(2.9 \times 10^4\) ft.
The correct response is:
**2.9×10⁴ ft.**
