Question

The mass of the Eiffel Tower is about 9.16 ⋅ 106 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 108 kilograms. Approximately how many more kilograms is the mass of the Golden Gate Bridge than the mass of the Eiffel Tower? Show your work and write your answer in scientific notation.

Answer 1

Given:

• Mass of the Eiffel tower = $9,16,106kilograms$
• Mass of the Golden Gate Bridge = $8,05,108kilograms$

To find:

To find how much more the Eiffel tower weighs than that of the Golden Gate Bridge, i.e., the difference between the weights of the Eiffel tower and the Golden Gate Bridge.

To be recollected:

• Eiffel tower, which is constructed using Wrought iron, is situated in Paris.
• It was built to celebrate French revolution's centennial, in the year 1889.
• Golden Gate Bridge is a suspension bridge, that connects San Francisco bay to the Pacific ocean, which is constructed in 1937.

Formula to be used:

• The purpose is to find the difference between the weights of the Eiffel tower and the Golden Gate Bridge.
• To find the required difference, the weight of Golden Gate Bridge is to be subtracted from the weight of the Eiffel tower.
• Let the weight of the Eiffel tower be denoted by "$E$" and the weight of Golden Gate Bridge be denoted by "$G$".
• Let the difference in their weights be denoted by "$D$".
• Now, the formula for finding the difference between the weights is given by:

$D=E-G$....(1)

Solution:

Using the given data and the equation (1), the required difference in the weights is calculated in the following way:

$D=E-G\\D=9,16,106-8,05,108\\D=1,10,998kilograms$

⇒ The required difference between the weights of the Eiffel tower and the Golden Gate Bridge is $1,10,998kilograms$.

Final Answer:

∴The Eiffel tower is $1,10,998kilograms$ heavier than the Golden Gate Bridge.

Answer 2

9.16 times 10^6 minus 8.05 times 10^8 

well... we need to rearrange this problem. 

9.16 times 8.05 minus 10^6 times 10^8 

10^6 plus 10^8 is 10^16 

9.16 plus 8.05 is 17.21  

so... 17.21 - 10^16?
