Answer:
of the bottle was used
Step-by-step explanation:
Amount of cleaning solution present in spray bottle = 
of the bottle
Amount of cleaning solution present in the spray bottle used = 
of the cleaning solution present initially
To find:
How much of the bottle was used?
Solution:
Here, we need to find how much amount of the cleaning solution spray was used from the complete bottle.
Amount of spray used = 
of the cleaning solution = of the cleaning solution.
Therefore, the answer is:
of the bottle was used
Answer:
I think it's 2.5
Step-by-step explanation:
Since the Chilean earthquake was 9.5 and Haiti was 7.0 the just subtract from the 9.5 to get the greater. Obviously a 9.5 on the Richter scale is going to do way more damage either way. I apologize if I'm wrong, bit I think it's 2.5 (If not that selection choose 2) Have a great day loves!! <3
Answer:
p=122
q=90
Step-by-step explanation:
p=180-58=122
q=180-90=90
Answer:
Step-by-step explanation:
Given that a solution containing 12% alcohol is to be mixed with a solution containing 4% alcohol to make 20 gallons of solution containing 9% alcohol.
Let x gallons of 12% alcohol be mixed with y gallons of 4% alcohol.
Total gallons
Alcohol content in the total mixture 
b) Two equations are
c) This is of the form Ax = B
where A =![\left[\begin{array}{ccc}1&1\\12&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%261%5C%5C12%264%5Cend%7Barray%7D%5Cright%5D)
Inverse is ![\frac{1}{4-12} \left[\begin{array}{ccc}4&-1\\-12&12\end{array}\right]\\=\frac{-1}{8} \left[\begin{array}{ccc}4&-1\\-12&12\end{array}\right]\\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4-12%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%26-1%5C%5C-12%2612%5Cend%7Barray%7D%5Cright%5D%5C%5C%3D%5Cfrac%7B-1%7D%7B8%7D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D4%26-1%5C%5C-12%2612%5Cend%7Barray%7D%5Cright%5D%5C%5C)
Solution set is A inverse *B
=
