I need to answer this using dimensional analysis and the answer must be written in Scientific notation. I can't figure it out.

3.343481472 x 10^4

Step-by-step explanation:

11.6 a = 3.25 *

6.18 * = 2.5 #

Take the first equation and solve for *

11.6 a = 3.25 *

Divide each side by 3.25

11.6 a/3.25 = *

3.569230769 a = *

Substitute this into the second equation for *

6.18  (3.569230769 a)  = 2.5 #

22.05784615 a =  2.5 #

Solve for a

Divide by 22.05784615

a = 2.5 # /  22.05784615

a = .113338355

We have 2.95 x 10 ^5 a

2.95 x 10 ^5  ( .113338355)

33434.81472

Changing to scientific notation

3.343481472 x 10^4
