Answer:
12
Step-by-step explanation:

Are you sure that both a and b are zero?
I doubt it.
<span>-8a^8b^-2/10a^-4b^-10
should surely be written as a fraction for clarity:
</span><span>-8a^8b^-2
----------------- (at least this is how I interpret your question)
10a^-4b^-10
-8a^8 divided by 10a^(-4) comes out to (-8/10)a^12, and
b^(-2) divided by b^(-10) comes out to b^8
so that your final quotient is (-4/5)(a^12)(b^8).</span>
<span>2153.28 hundreds to be exact or, 2153.</span>
Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.
We find fraction of whole wheat bagels to the sample for each shop using given information
Shop A = 
Shop B = 
Shop C = 
The number of whole wheat bagels for each shop that sells 500 bagels per day
Shop A = 
Shop B = 
Shop C = 
To find the percent you would divide 591 by 2364
591/2364=.25
.25*100 = 25%
Does that make sense?
