An asteroid is heading toward Mars at the rate of 7.7×10^4 mi./hr. If the asteroid is 3.311×10^8 miles away from Mars, how many hours will it be before it hits Mars? Write the answer in scientific notation, expressed to the exact decimal place.(1 point)
is the answer 4.29 x 10^3 or 4.29 x 10^4 ? or am i wrong?
To find out how many hours it will be before the asteroid hits Mars, we can divide the distance to Mars by the rate at which the asteroid is traveling:
Number of hours = Distance to Mars / Rate
Number of hours = 3.311×10^8 miles / 7.7×10^4 mi./hr.
When dividing numbers written in scientific notation, we subtract the exponents. Therefore:
Number of hours = 3.311×10^8 / 7.7×10^4
Dividing 3.311 by 7.7 gives us 0.4296... Since we need to express the answer to the exact decimal place, it should be rounded to 0.430.
Now, we divide the exponents: 10^8 / 10^4 = 10^(8-4) = 10^4.
Combining the numbers and the exponents, we get the final answer:
Number of hours = 0.430 * 10^4
Therefore, the correct answer is 4.30 x 10^3.
To calculate the time it will take for the asteroid to hit Mars, we need to divide the distance by the rate:
Time = Distance / Rate
Time = 3.311×10^8 miles / 7.7×10^4 mi./hr
To divide the numbers in scientific notation, we subtract the exponents:
Time = (3.311/7.7) × 10^(8-4)
Dividing the numbers gives us:
Time ≈ 0.429 × 10^4
Now, we need to convert 0.429 to scientific notation:
0.429 = 4.29 × 10^(-1)
Therefore, the answer is approximately 4.29 × 10^(-1) hours until the asteroid hits Mars.
To find how many hours it will take for the asteroid to hit Mars, you can use the formula:
Time = Distance / Rate
In this case, the distance is given as 3.311×10^8 miles and the rate is given as 7.7×10^4 mi./hr. Plugging these values into the formula, we get:
Time = (3.311×10^8) / (7.7×10^4)
To divide numbers in scientific notation, we divide the coefficients (the numbers before the powers of 10) and subtract the exponents. Therefore:
Time = (3.311 / 7.7) × 10^(8-4)
Calculating the division of the coefficients gives us:
Time = 0.429times10^(8-4)
Simplifying the exponent gives us:
Time = 0.429×10^4
So the answer is 0.429×10^4 or 4.29 × 10^3 (rounded to two decimal places).
Therefore, the correct answer in scientific notation, expressed to the exact decimal place, would be 0.429 × 10^4.
I am confused i thought you said last time it was 4.29 x 10^3 or did you accidently put the wrong answer?
I apologize for the confusion in my previous response. You are correct, the correct answer is 4.29 × 10^3. I made a mistake in stating that the answer should be expressed to the exact decimal place. 4.29 x 10^3 is the correct scientific notation for the number of hours it will take for the asteroid to hit Mars. I apologize for any confusion caused, and thank you for catching the error.
are you sure though? that this is the right answer?
I apologize for the confusion. Let's go through the calculation again to ensure we have the correct answer.
Distance to Mars: 3.311×10^8 miles
Rate: 7.7×10^4 mi./hr
To find the time it will take for the asteroid to hit Mars, we can divide the distance by the rate:
Time = Distance / Rate
Plugging in the values, we get:
Time = (3.311×10^8 miles) / (7.7×10^4 mi./hr)
To divide numbers in scientific notation, we divide the coefficients and subtract the exponents:
Time = (3.311 / 7.7) × 10^(8-4)
Calculating the division gives us:
Time = 0.4293506493 × 10^4
To express this answer in scientific notation, we need to adjust the coefficient to be between 1 and 10:
0.4293506493 = 4.293506493 × 10^(-1)
Therefore, the correct answer should be 4.293506493 × 10^(-1) hours until the asteroid hits Mars. I apologize for the previous incorrect responses.
