Answer:
You are at the top of the Empire State Building on the 102nd floor, which is located 373 m above the ground when your favorite superhero flies over the building parallel to the ground at 70.0% the speed of light.
You have never seen your favorite superhero in real life. Out of curiosity you calculate her height to be 1.57 mm . If the superhero landed next to you, how tall would she be when standing?
Step-by-step explanation:
so this problem is from Einstein's special theory of relativity about length contraction.
the formula is given by:
where 
c is speed of light 
and v is velocity of object.
L is called proper length. L' is length that the observer measure in moving frame.
here velocity of object is 70% speed of light. i.e 
so 
putting all values
Since one nickel equals 5 cents, you'd multiply 10 nickels by 5 cents apiece and yield 50 cents to spend.
Answer: 3
Step-by-step explanation:
11- 2x2x2 since its 2 to the power of 3 which will give you 8 and than you basically just subtract 11- 8=3
Answer:46
Step-by-step explanation:if a =6, then a^2 would be 36, and if you add b(10) to that, you get 46
Alright! Given that C(x) is Cost(Students) = 558, we can eliminate:
2. 558 students paid to attend the event.
5. The event generated $124 from student revenue.
Now, in order to find the cost per student we simply divide 124 on both sides:
124 cancels on the left and 558/124 is 4.5 or $4.50.
Since we just determined the cost of one student, we can eliminate 3.
To check if 124 students paid, we simply add the cost to the equation and check:
4.5(124) = 558
558 = 558 √
It checks out, so we determined that both 1 and 4 are correct.
