5.80x10(9)s + 3.20x10(8)s

In order to add or subtract numbers expressed in scientific notation, it is important that the powers of 10 in the numbers should have the same index or else you cannot readily add or ubtract these numbers. We do as follows: a. 5.80 x 10^9 s +3.20 x 10^8 s We need to adjust one of the numbers since they do not have the same indices. We move one place to the left of the second number making it .320 x 10^9 s. Then, we can add the numbers now:

5.80 x 10^9 s +.320 x 10^9 s = 6.12 x 10^9 s

Explanation:

5.80 x 10^9 s +.320 x 10^9 s = 6.12 x 10^9 s

We can subtract the numbers directly since they have the same indices.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is
