Please help me with the following:
Find each product or quotient. Use significant digits.
0.0505m x 665m
A. 33.6 m^2
B. 33.58 m^2
C. 33.50 m^2
D. 3.582 m^2
I think the answer is A. Is this correct?
Please help me by checking my answer. Any help will be appreciated!! :)
P.S.: There may be more that need checking.
correct.
Thank you Bob! :)
Determine the number of significant digits in the measurement.
80.00 kg
the answer is 4
To find the product, we need to multiply 0.0505m by 665m. Here's how you can calculate it:
Step 1: Multiply the numbers without considering significant digits.
0.0505m * 665m = 33,632.5m^2
Step 2: Determine the number of significant digits in each factor.
0.0505 has 3 significant digits.
665 has 3 significant digits.
Note: In multiplication, the product can have no more significant digits than the factor with the least number of significant digits.
Step 3: Round the product to the correct number of significant digits.
Since both factors have 3 significant digits, we round the product to 3 significant digits.
Now, let's look at the answer choices:
A. 33.6 m^2 - This answer has one decimal place, which does not match the three significant digits we calculated.
B. 33.58 m^2 - This answer has two decimal places, which does not match the three significant digits we calculated.
C. 33.50 m^2 - This answer has three decimal places, matching the three significant digits we calculated.
D. 3.582 m^2 - This answer has four decimal places, which does not match the three significant digits we calculated.
Based on our calculations, the correct answer is C. 33.50 m^2. Therefore, the answer you selected (A) is incorrect.
