12. A chemist has 40 mL of a solution that is 50% acid. How much water should he add to make
a solution that is 10% acid?
Total Amount x % Acid = Amount of Acid
Total Amount
% Acid
Amount of Acid
Original Solution
Water
New Solution
Answers
Answer:
Volume of pure Acid in -50- LITRES of the solution= 10- litres. Let “V”- litres of water be added, then
Therefore 10= (50+ V) x8/100 .
So 10= 4 + 8V/100
8V/100 = 10–4= 6
So V= 6 x 100/8= 600/8= 75- LITRES.
So on adding 75- litres of water to the acid solution, the percentage of acid drops to 8% .
Check: Percentage of acid in 125- LITRES of acid solution, which contain 10- LITRES if pure Acid
= 10/125 x 100= 8% .

Answer:
question 1: it is between 8 and 9. question 2: option B.
Step-by-step explanation:
1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that the square root of 66 is between 8 and 9.
2. to solve this, we can take the square root of the numbers to begin.
the square root of 25 is 5 (because 5x5=25)
the square root of 16 is 4
20 is actually not squarable, so we can estimate that it is a little greater 4.
the answer would be √16, √20, 4.85, √25
it would be option b.

Write each Quadratic function in standard form. The 2 picture is my notes to help with the answer.
Answers
Answer:
33) 4x² + 8x + 1
35) -2x² + 36x - 147
Step-by-step explanation:
#33: f(x) = 4(x+1) ² - 3
f(x) = 4(x+1) ² - 3
First Step: Multiply (x+1) (x+1)
(x + 1)² or (x+1)(x+1) is a one real double.
A one real double means that there is only one real solution
(x + 1) (x + 1) = x² + 2x + 1
Second Step: Multiply x² + 2x by 4
4(x² + 2x + 1) = 4x² + 8x + 4
Final Step: Put -3 in the Quadratic Function and do -3 + 4 to get your constant
4x² + 8x - 3 + 4
= 4x² + 8x + 1
#35: f(x) = -2(x - 9) ² + 15
First Step: Multiply (x - 9) (x - 9)
Remember, (x - 9) ² or (x - 9) · (x - 9) is a one real double, meaning that there is only one real solution.
(x - 9) (x - 9) = x² - 18x + 81
Second Step: Multiply by -2
-2 (x² - 18x + 81) = -2x² + 36x - 162
Final Step: Add the constant by 15 in the equation. (Hint: the constant is -162)
-2x² + 36x - 162 + 15
= -2x² + 36x - 147
This is how you convert the function into standard form. Hope this helps.
