The average distance from Earth to Mars is 2.25×10^8 km, and the distance from Earth to Neptune is 4.3514×10^9 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer.(1 point)
To find the difference between the distances from Earth to Mars and Neptune, we subtract the distance from Mars from the distance from Neptune:
4.3514×10^9 km - 2.25×10^8 km = 4.3514×10^9 km - 0.225×10^9 km = 4.1264×10^9 km
Therefore, Neptune is 4.1264×10^9 km farther from Earth than Mars.
Human hair grows at a rate of about 6.849×10^−4 cm per hour to 2.329×10^−2 cm per hour. The rate depends on gender, genetics, age, and health. Find the difference between the high end and the low end of the range. Express your answer in scientific notation. Do not round your answer.(1 point)
wrong idiot
wrong
Find 0.078−(5.2×10^−3) . Express your answer in scientific notation. Do not round your answer.(1 point)
To subtract the values 0.078 and 5.2×10^-3, we can write the expression as:
0.078 - 5.2×10^-3 = 0.078 - 0.0052
Now we can subtract the decimal values:
0.078 - 0.0052 = 0.0728
Therefore, the answer is 0.0728 expressed in decimal notation.
stupid bot. ur wrong
To find the difference between the high end and low end of the hair growth rate range, we subtract the low end from the high end:
2.329×10^−2 cm per hour - 6.849×10^−4 cm per hour = 2.329×10^−2 cm per hour - 0.006849×10^−2 cm per hour
= 2.329×10^−2 cm per hour - 0.006849×10^−2 cm per hour
= (2.329 - 0.006849) × 10^−2 cm per hour
= 2.322151 × 10^−2 cm per hour
Therefore, the difference between the high end and the low end of the range is 2.322151 × 10^−2 cm per hour.
I apologize if my previous response was incorrect or insufficient. To find the difference between the high end and low end of the hair growth rate range, we subtract the low end from the high end:
2.329×10^−2 cm per hour - 6.849×10^−4 cm per hour = (2.329 - 0.0006849) × 10^−2 cm per hour = 2.3283151 × 10^−2 cm per hour
Therefore, the difference between the high end and the low end of the range is 2.3283151 × 10^−2 cm per hour.
I apologize for any confusion caused. Let's try calculating it again.
The difference between the high end and low end of the hair growth rate range is:
2.329×10^−2 cm per hour - 6.849×10^−4 cm per hour = 2.329×10^−2 cm per hour - 0.0006849×10^−2 cm per hour
= (2.329 - 0.0006849) × 10^−2 cm per hour
= 2.3283151 × 10^−2 cm per hour
Therefore, the difference between the high end and the low end of the range is 2.3283151 × 10^−2 cm per hour.
