Answer:
6
Step-by-step explanation:
(2.4×10³)×(3×10^x)=7.2×10^9
(3x10^x)=(7.2×10^9)/(2.4×10^3)
3×10^x=3×10^6
10^x=10^6
*when bases are same ,powers are equated*
thus x=6

Step-by-step explanation:
Answer:
- 4.2 degrees
Step-by-step explanation:
If the drop was from temp 0 at 8 pm to temp -16.8 at midnight (4 hours later)

Therefore, at 9 pm the temperature was:
0 degrees - 4.2 degrees = - 4.2 degrees
