Vf = Vi + at 
Vf = 0 + (9.81 m/s^2)(3 seconds) 
Vf = 29.43 m/s and or about 29.4 m/s

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.

I need to know 7 divided by 4/5 =
Basile [38]

Answer:

8.75 or 8 3/4

Step-by-step explanation:7

   

The numbers in 7 divided by 4/5 are labeled below:

7 = whole number

4 = numerator

5 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

7 x 5

4

 =    

35

4

Thus, the answer to 7 divided by 4/5 in fraction form is:

35

4

To make the answer to 7 divided by 4/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

35 / 4 = 8.75

The answer is rounded to the nearest two decimal points if necessary.

35/4 is an improper fraction and should be written as 8 3/4.
