The mass of the Eiffel Tower is about 9.16 ⋅ 10^6 kilograms. The mass of the Golden Gate Bridge is 8.05 ⋅ 10^8 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:
by [tex]\bf 7.96 *10^6[/tex] , the mass of the golden gate is larger than the Eiffel Tower
Step-by-step explanation:
[tex]\large \boldsymbol {} \sf 8,05\cdot 10^8-9,16\cdot 10^6 = 805\cdot 10^6-9,16\cdot 10^6 = \\\\ 10^6(805-9,16)=10^6\cdot 795,86 \\\\ Standart \ form \ 10^6\cdot 795,86 \approx 10^8\cdot 7,96 \ kg[/tex]
Answer:
7.96 × 10⁸ kg moreStep-by-step explanation:
Subtract the mass Eiffel Tower from the mass Golden Gate Bridge:
8.05 × 10⁸ - 9.16 × 10⁶ = (805 - 9.16) × 10⁶ = 795.84 × 10⁶ =7.96 × 10⁸ kgIs this pounds or Ounces?
lb:oz
Well... lb is pounds, and oz is ounces, so Maybe it's in both pounds and ounces? For instance, 2 pounds 3 ounces is equal to 35 ounces...

Determine the intercepts of the line. Do not round your answers. 2 x + 5 y = − 6
The y-intercept for the line, 2x + 5y = -6, is: 1.2.
Equation of a Line in Slope-Intercept FormThe equation of a line can be represented in slope-intercept form as: y = mx + b."b" is the y-intercept.Given:
2x + 5y = -6
Rewrite in slope-intercept form
5y = -2x - 6
Divide both sides by 5y = -2/5x - 6/5
"b" = -6/5 = 1.2
Therefore, the y-intercept for the line, 2x + 5y = -6, is: 1.2.
