Answer:
Second option: 5E 10 = 5*10^(10) galaxies.
Step-by-step explanation:
The exponential notation is used as:
AE N
This is equal to:
A*10^(N)
And we need to add N zeros to the right of A.
While if we had:
AE - N
A*10^(-N)
We need to add N - 1 zeros at the left of A.
Now we have the number:
50,000,000,000
Let's count the number of zeros at the right of the 5, we have 10 zeros.
Then we would write this as:
5*10^(10)
OR
5E 10
Then the correct option is the second one.
A. 3
B. 4
C. 6
D. 2
E. 1
F. 7
G. 5
This is my guess by looking at it. I just started doing this too.
Janet ran 100 meters in 15 seconds. How long did she take to run 2 meters?
Solution:
100/15 = y/2
Solve for y.
y = (15/100)(2)
y = 0.3
Answer: She took 0.3 seconds.
