How many gallons of pure water should be evaporated from 160 gallons of a solution containing 12% salt
so that the remaining solution contains 20% salt?
What are you being asked to find in this problem?
O gallons of pure water
gallons of 12% salt solution
gallons of 20% salt solution
what is the original amount of solution in gallons? a=
Answer:
66 gallons
Step-by-step explanation:
Given that initially 160 gallons of a solution containing 12% salt.
So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.
Let x gallons of water get evaporated so that the remaining solution contains 20% salt.
The remaining amount of solution = 160-x gallons.
As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so
19.2 = 20% of (160-x)
[tex]\Rightarrow 19.2 = \frac {20}{100}\times (160-x) \\\\\Rightarrow 19.2 = \frac {1}{5}\times (160-x) \\\\\Rightarrow 19.2 \times 5= 160-x \\\\\Rightarrow 96= 160-x \\\\\Rightarrow x= 160-96 \\\\[/tex]
[tex]\Rightarrow x= 66[/tex] gallons
Hence, 66 gallons of water must be evaporated to get a 20% salt solution.

Click on the measure of the angle.
Answer:
Wow that's hard to look at. But, when zooming in, we can see that the arrow is closer to 116 degrees, so that is the answer.
Step-by-step explanation:
Notice that the angle/arrows is opening up from right to left, so it will be greater than 90 degrees. The arrow is a little bit more than 115 degrees, so it has to be 116 degrees.

Write a paragraph with at least four reasons explaining why parental controls are bad for kids.
1.your child will become a nervous person and develop anxiety being over controlling will put their mind in a small cage in which they can barely move
2.the choice to use parental controls undermines the trust in your relationship with your child and it reduces your child's opportunity to make smart choices and to take responsibility for the actions they choose
3. your child will most likely reveal and still find ways to look at things you have blocked rebelling against the world isn't the same as rebelling against your parents rebelling against the system isn't the same as rebelling against household rules children need a certain level of Freedom if you try to control every aspect of their lives they'll reclaim their autonomy more and more forcefully and probably Less Reasonable
4.you'll discourage their creativity if you constantly control what your child doesn't turn them into your Shadow they'll probably be less created as a result

Answer:
1) Infinitely many solutions.
2) No real solutions.
3) (-1, 2)
Step-by-step explanation:
The solutions of a system of linear equations is whenever the two lines intersect.
However, if the two lines never intersect (they are parallel), then there are no solutions.
And if the two lines are the same line, then there are infinitely many solutions.
First Graph:
The two lines are exactly the same.
Hence, there are infinitely many solutions.
Second Graph:
The two lines are parallel. They will never intersect each other.
Therefore, there are no real solutions.
Third Graph:
The two lines intersect at the point (-1, 2).
Hence, there is only one solution and it is (-1, 2).

Answer:
A) x=8 and angle ABC=115 degrees
Step-by-step explanation:
the lines are parallel, meaning the angles are congruent.
you can set up the equation (15x-5)=(10x+35) and simplify.
1. separate variable by subtracting 10x on both sides to get (5x-5)=(35)
2. add 5 on both sides to get 5x=40
3. divide both sides by 5 to get x=8
4. plug x=8 into original function (10x+35) to get (10(8)+35) which equals 115 degrees
How do I solve 6a + 5a = −11
Answer:
a = - 1
Step-by-step explanation:
Step 1:
6a + 5a = - 11 Equation
Step 2:
11a = - 11 Combine Like Terms
Step 3:
a = - 11 ÷ 11 Divide
Answer:
a = - 1
Hope This Helps :)
The solution to the equation 6a + 5a = -11 is a = -1.
We have,
To solve the equation 6a + 5a = -11, we can combine the like terms on the left side of the equation and then isolate the variable a.
Step 1: Combine like terms
On the left side, we have 6a + 5a, which gives us 11a. The equation becomes:
11a = -11
Step 2: Isolate the variable
To isolate variable a, we divide both sides of the equation by 11:
(11a) / 11 = (-11) / 11
a = -1
Therefore,
The solution to the equation 6a + 5a = -11 is a = -1.

I need to fine the midpoint of this slope they gave me
Answer:
The midpoint would be (-3, 1)
Step-by-step explanation:
since the formula for midpoint is [tex](\frac{x^{1} +x^{2} }{2}, \frac{y^{1} +y^{2} }{2} )[/tex], you would just have to plug in the coordinates given on the graph. I think your points are (-1, 4) and (-5, -2).
[tex](\frac{-1 -5}{2}, \frac{4-2}{2} )[/tex]
[tex](\frac{-6}{2}, \frac{2}{2} )[/tex]

You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions.
9 ft x 9 ft
Answer:48.6
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 81 square feet
45(81)/75=48.6
hope this helped and I hope you get a correct answer :D
Answer:
48.6 minutes
Step-by-step explanation:
First we must identify the area of the given wall :
A = L * W
A = 9 * 9
81 = 9 * 9
[tex]81ft^2[/tex]
Now we know that we can paint 75 square feet every 45 minutes so we must use proportion to find out how long it'll take you.
[tex]\frac{75}{45} *\frac{ft^2}{min}[/tex]
=
[tex]\frac{81}{x}[/tex] [tex]\frac{ft^2}{min}[/tex]
x = 45(81) / 75
x = 3645 / 75
x = 48.6 minutes
