How many quarts of a 50% solution of acid must be added to 20 quarts of a 20% solution of acid to obtain a mixture containing a 45% solution of acid?
Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.

In a survey of 800 people, 32% preferred cats and 27% preferred dogs. How many more people preferred cats than preferred dogs?
Calculate the amount of people on both sides.
32% preferred cats
32% of 800
0.32 × 800 = 256 people
27% preferred dogs
27% of 800
0.27 × 800 = 216 people
So 256 people preferred cats and 216 people preferred dogs.
256 - 216 = 40 people
40 more people preferred cats than preferred dogs
40 people preferred cats more than preferred dog.
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
Total number of people participated in survey = 800.
Percentage of people who preferred cats = 32%,
And percentage of people who preferred dogs = 27%.
The percentage of people who preferred cats more than preferred dogs
= 32 - 27
= 5 %
The number of people preferred cats more than preferred dogs
= 800 x 5/100
= 40.
There are 40 more people preferred cats than dog.

Answer:
The angle between the two sides of the right triangle is aproximately 31.003º.
Step-by-step explanation:
From image attached on question we infer that we need to find the angle between sides of lengths 6 (adjacent leg) and 7 (hypotenuse) in the right triangle. The angle can be found by means of this trigonometric ratio:
[tex]\cos \alpha = \frac{6}{7}[/tex]
[tex]\alpha = \cos^{-1} \frac{6}{7}[/tex]
[tex]\alpha \approx 31.003^{\circ}[/tex]
The angle between the two sides of the right triangle is aproximately 31.003º.
class A has 11 pupils and class B has 14 pupils. Both classes sit the same maths test. the mean score for class A is 32. The mean score for class B is 38. What is the mean score(rounded to 2DP) in the maths test across both classes?
Answer:
35.36
Step-by-step explanation:
For Class A
Class A has 11 pupils
The mean score for Class A is 32.
The total score of the students =
Mean score × Number of pupils
= 32 × 11
= 352
For Class B
Class B has 14 pupils. The mean score for class B is 38.
The total score of the students =
Mean score × Number of pupils
= 38 × 14
= 532
Total number of pupils for both classes = (11 + 14)pupils
= 25 pupils
Total score for both class = 532 + 352
= 884
The mean score(rounded to 2DP) in the maths test across both classes is calculated as:
Total score of both classes÷ Total number of pupils
884 ÷ 25
35.36

What is the expression in factored form?
2x^2+16x+24
Is it (x-2)*(x-6) or 2(x-2)*(x-6)?
Answer:
( 2x +4) ( x+6)
Step-by-step explanation:
Explanation:-
Given expression 2 x² + 16 x + 24
The factors of 48 = 12 × 4
⇒ 2 x² + 16 x + 24
⇒ 2 x² + 12 x + 4x + 24
⇒ 2 x ( x +6 ) + 4( x +6)
⇒ ( 2x +4) ( x+6)

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityAlgebra I
Terms/CoefficientsStep-by-step explanation:
Step 1: Define
3.6y = 1.6y + 24
Step 2: Solve for y
[Subtraction Property of Equality] Subtract 1.6y on both sides: 2y = 24[Division Property of Equality] Divide 2 on both sides: y = 12Step 3: Check
Plug in y into the original equation to verify it's a solution.
Substitute in y: 3.6(12) = 1.6(12) + 24Multiply: 43.2 = 19.2 + 24Add: 43.2 = 43.2Here we have 43.2 does indeed equal 43.2.
∴ y = 12 is the solution to the equation.

x is part of a 30 60 90 triangle.
so x is 4[tex]\sqrt{3}[/tex]
next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.
4 + 6 = 10
10^2 = 100
100 = a^2 + b^2
y = 6 and z = 8 bc 36 + 64 = 100

so my brother asked another question. He asked what is the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter of the room? how the question goes. (the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter os the room?
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.
Let me know if this helps!

Step-by-step explanation:
The perimeter of the room is 60
