Calculate 6.25×10^6−4.73×10^6 . Express your answer in scientific notation to 2 decimal places. (1 point)
To subtract these numbers in scientific notation, we need to have the same exponent. Let's rewrite the numbers to have the same exponent:
6.25 × 10^6 - 4.73 × 10^6
= (6.25 - 4.73) × 10^6
= 1.52 × 10^6
Expressing this in scientific notation to 2 decimal places, the answer is:
1.52 × 10^6
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 in distance between Neptune and Mars, we subtract the average distance from Earth to Mars from the distance from Earth to Neptune:
4.3514 × 10^9 km - 2.25 × 10^8 km
Subtracting these numbers gives us:
4.3514 × 10^9 - 2.25 × 10^8
We cannot directly subtract these numbers since the exponents are different. To subtract them, we need to rewrite the numbers with the same exponent:
4.3514 × 10^9 km = 435.14 × 10^7 km (by dividing the exponent by 2)
Now we can subtract:
435.14 × 10^7 km - 2.25 × 10^8 km
Subtracting gives us:
(435.14 - 2.25) × 10^8 km
= 432.89 × 10^8 km
Finally, we express the answer in scientific notation:
4.3289 × 10^10 km
Therefore, Neptune is 4.3289 × 10^10 km farther from Earth than Mars.
it says dont round the answer
Apologies for the confusion. In this case, we can express the answer without rounding it:
4.3289 × 10^10 km
it says its wrong
Apologies for the mistake. Let's recalculate the difference without rounding:
4.3514 × 10^9 km - 2.25 × 10^8 km
To perform this subtraction, we need to rewrite the numbers in the same exponential form:
4.3514 × 10^9 km = 435.14 × 10^7 km
Now we can subtract:
435.14 × 10^7 km - 2.25 × 10^8 km
Performing the subtraction gives us:
(435.14 - 2.25) × 10^7 km
= 432.89 × 10^7 km
Expressing the answer in scientific notation without rounding, we have:
4.3289 × 10^8 km
Therefore, Neptune is 4.3289 × 10^8 km farther from Earth than Mars.
still says ur wrong
I apologize for the previous incorrect responses. Let's recalculate the difference between Neptune and Mars without rounding:
4.3514 × 10^9 km - 2.25 × 10^8 km
To subtract these numbers, we need to have the same exponent. Let's rewrite the numbers to have the same exponent:
4.3514 × 10^9 km = 435.14 × 10^7 km
Now we can subtract:
435.14 × 10^7 km - 2.25 × 10^8 km
Performing the subtraction gives us:
(435.14 - 2.25) × 10^7 km
= 432.89 × 10^7 km
Expressing the answer in scientific notation without rounding, we have:
4.3289 × 10^9 km
Therefore, Neptune is 4.3289 × 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)
To find the difference between the high end and low end of the range, we subtract the low end from the high end:
2.329 × 10^(-2) cm/hr - 6.849 × 10^(-4) cm/hr
To subtract these numbers, we need to have the same exponent. Let's rewrite the numbers with the same exponent:
2.329 × 10^(-2) cm/hr = 0.02329 × 10^(-2) cm/hr
Now we can subtract:
0.02329 × 10^(-2) cm/hr - 6.849 × 10^(-4) cm/hr
Performing the subtraction gives us:
(0.02329 - 0.0006849) × 10^(-2) cm/hr
= 0.0226051 × 10^(-2) cm/hr
Expressing the answer in scientific notation, we have:
2.26051 × 10^(-4) cm/hr
Therefore, the difference between the high end and low end of the range is 2.26051 × 10^(-4) cm/hr.
DONT ROUND
Apologies for the misunderstanding. Let's recalculate the difference without rounding:
2.329 × 10^(-2) cm/hr - 6.849 × 10^(-4) cm/hr
To subtract these numbers, we need to have the same exponent. Let's rewrite the numbers with the same exponent:
2.329 × 10^(-2) cm/hr = 0.02329 × 10^(-2) cm/hr
Now we can subtract:
0.02329 × 10^(-2) cm/hr - 6.849 × 10^(-4) cm/hr
Performing the subtraction gives us:
(0.02329 - 0.0006849) × 10^(-2) cm/hr
= 0.0226051 × 10^(-2) cm/hr
Expressing the answer in scientific notation without rounding, we have:
2.26051 × 10^(-4) cm/hr
Therefore, the difference between the high end and low end of the range is 2.26051 × 10^(-4) cm/hr.
Find 0.078−(5.2×10^−3) . Express your answer in scientific notation. Do not round your answer.(1 point
To calculate 0.078 - (5.2×10^(-3)), we need to subtract the second number from the first:
0.078 - (5.2×10^(-3))
To subtract these numbers, we don't need to adjust the exponents since they are already the same. We can perform the subtraction directly:
0.078 - 0.0052 = 0.0728
Expressing the answer in scientific notation without rounding, we have:
7.28×10^(-2)
Therefore, the answer is 7.28×10^(-2) in scientific notation.
Earth’s radius is approximately 3,959 miles, while Jupiter’s radius is approximately 4.3441×10^4 miles. How much bigger is Jupiter’s radius compared to Earth’s? Express your answer in scientific notation. Do not round your answer.(1 point)
To find how much bigger Jupiter's radius is compared to Earth's, we subtract Earth's radius from Jupiter's radius:
4.3441×10^4 miles - 3,959 miles
To subtract these numbers, we need to convert Earth's radius to scientific notation:
3,959 miles = 3.959 × 10^3 miles
Now we can subtract:
4.3441×10^4 miles - 3.959 × 10^3 miles
Performing the subtraction gives us:
(4.3441 - 3.959) × 10^4 miles
= 0.3851 × 10^4 miles
Expressing the answer in scientific notation without rounding, we have:
3.851×10^3 miles
Therefore, Jupiter's radius is 3.851×10^3 miles bigger than Earth's radius.
