13a.) If you're dividing and the base (in this case the base is 10) is the same, subtract the exponents.

13b.) If you're multiplying and the base is the same, then you add the exponents:

13c.) This is similar to 13b:
c = cost
h = # of half-dozens ordered
c = $8.50h + $1 is the correct answer.
I would say the answer would be 29.17% because
=29.17%
Hope this helps
I'm so sorry if this is wrong
have a great day/night
Answer:
a) 4 - 
b) 1 - 
c) 6 - 
Step-by-step explanation:
It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.
We start with:

We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):

Then we multiply each side by 2 to get rid of the 1/2, answer #1:

Finally, we divide each side by t^2 to isolate a (answer #6):

Answer:</h2>
The answer is 25 minutes
<h2>
Step-by-step explanation:</h2>
As we see the median time given in minutes before the installation was 53 minutes and after the installation it became 28 so by taking the difference which is 53 - 28 gives us 25 minutes.
