what's the definition of electrolysis
Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

In ΔHIJ, h = 450 cm, i = 210 cm and j=640 cm. Find the measure of ∠I to the nearest degree.
Answer:
10
Step-by-step explanation:
The measure of an angle∠I is 10 degrees between the 450 cm and 640 cm sides.
What is the Cosine Rule?The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
c² = a² + b² − 2ab cos(C)
The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.
In the given triangle ΔHIJ,
Sides:
h = 450 m
i = 210 m
j = 640 m
The angle of ∠I is 10 degrees between the 450 cm and 640 cm sides.
According to the cosine rule,
j² = h² + i² − 2ab cos(I)
Substitute the values in the Cosine Rule,
450² = 210² + 640² - 2(210)(640)cos(I)
After solving we get the value of angle ∠I :
∠I = 9.56038°
Rounded to the nearest degree.
∠I = 10°
Thus, the measure of an angle∠I is 10 degrees.

8(x – 3) – (6 – 2x) = 2(x + 2) – 5(5 – 2)
Answer:
x= [tex]\frac{19}{8}[/tex]
Step-by-step explanation:
8(x−3)−(6−2x)=2(x+2)−5(5−2)
Step 1: Simplify both sides of the equation.
8(x−3)−(6−2x)=2(x+2)−5(5−2)
8(x−3)+−1(6−2x)=2(x+2)−5(5−2)(Distribute the Negative Sign)
8(x−3)+(−1)(6)+−1(−2x)=2(x+2)−5(5−2)
8(x−3)+−6+2x=2(x+2)−5(5−2)
(8)(x)+(8)(−3)+−6+2x=(2)(x)+(2)(2)+−5(5−2)(Distribute)
8x+−24+−6+2x=2x+4+−15
(8x+2x)+(−24+−6)=(2x)+(4+−15)(Combine Like Terms)
10x+−30=2x+−11
10x−30=2x−11
Step 2: Subtract 2x from both sides.
10x−30−2x=2x−11−2x
8x−30=−11
Step 3: Add 30 to both sides.
8x−30+30=−11+30
8x=19
Step 4: Divide both sides by 8.
8x/8=19/8
Answer: x=[tex]\frac{19}{8}[/tex]
8(x - 3) - (6 - 2x) = 2(x + 2) - 5(5 - 2)
8*x - 8*3 - 6 + 2x = 2*x + 2*2 - 5*3
8x - 24 - 6 + 2x = 2x + 4 - 15 ( Cancel equal terms on both sides of the equation)
8x - 24 - 6 = 4 - 15
8x - 30 = -11
8x = -11 + 30
8x = 19
x = 19/8

Solve the equation 14=-(x-8)
Answer:
x = -6
Step-by-step explanation:
Answer:
x=-6
Step-by-step explanation:
14=-(x-8)
14=−x+8(Distribute)

−x+8=14
Subtract 8 from both sides
−x+8−8=14−8
−x=6
divide by -1 both sides
x=-6
At a football game three out of the first five student that arrived were wearing a jacket based on his information if 300 students attend the game how many students could be expected to not be wearing a jacket
Answer:
120 students students could be expected to not be wearing a jacket
Step-by-step explanation:
Based on this, we can work with the assumption that 3/5 of the students that entered the stadium were wearing jackets.
Given that the total population of students that attended the game is 300
This means that 3/5 of the 300 = 180 students.
180 students were estimated to be wearing jackets.
The number of students that were without jackets is 300 - 180 = 120 students
Find the equation of the line that passes through the points (-4,-2) and (-3,5) in both point-slope form and
slope-intercept form.
First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.
For slope:
[tex]m = \frac{5 + 2}{-3 + 4} = \frac{7}{1} = 7[/tex]
Slope (m) = 7
For y-intercept:
[tex]5 = 7(-3) + b\\\\5 = -21 + b\\\\26 = b[/tex]
Y-intercept (b) = 26
Using this information, we can now create the equations for this line.
[tex]y= 7x + 26\\\\y - 5 = 7(x + 3)[/tex]
Formulas:
Slope formula: y₂ - y₁/x₂ - x₁
Slope-intercept form: y = mx + b
Point-slope form: y - y₁ = m(x - x₁)
*Note: (x₁, y₁), (x₂, y₂) = 2 points on the line

Find the solution set for 8x - 3 = 2(x - 1/2)
Answer:
x = 1/3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
8x - 3 = 2(x - 1/2)
Step 2: Solve for x
Distributive 2: 8x - 3 = 2x - 1Subtract 2x on both sides: 6x - 3 = -1Add 3 to both sides: 6x = 2Divide 6 on both sides: x = 1/36-2x=3+5x
Whats the solution set?
Answer: The answer is x=3/7.
Step-by-step explanation:
So first you subtract on both sides by 5x and get -7x+6=3 then subtract 6 on both sides so you get -7x=-3 then lastly divide by -7 which is x=3/7. I hope this helps. The point of this problem is to isolate the x variable.
The solution to the equation 6 - 2x = 3 + 5x is x = 3/7.
Given that, the equation 6 - 2x = 3 + 5x.
As for an example of a different equation, consider the equation 2y + 5 = 17.
To solve this equation, isolate y:
2y = 17 - 5
2y = 12
y = 12/2
y = 6
The solution set for this equation is y = 6.
In general, the solution set can have various forms, such as a single value, multiple values, an interval, or even an infinite set of solutions, depending on the equation and its variables.
To solve the equation 6 - 2x = 3 + 5x, to isolate the variable x on one side of the equation.
Simplify the equation step by step:
6 - 2x = 3 + 5x
First, gather the x terms on one side and the constant terms on the other side:
-2x - 5x = 3 - 6
Combining like terms:
-7x = -3
Next, isolate x by dividing both sides of the equation by -7:
x = (-3) / (-7)
Simplifying the right side:
x = 3/7
The solution set is a collection of values or a range of values that satisfy the given equation. In this case, the solution set consists of a single value, which is x = 3/7.
Therefore, the solution to the equation 6 - 2x = 3 + 5x is x = 3/7.

field biologist collects 220 butterflies and moths. He collects 4 butterflies for every moth. How many butterflies and how many moths does he collect?
Answer:
The number of butterflies he collects = 176
The number of moth he collects = 44
Step-by-step explanation:
This question has to do with ratio.
We are told in the question that:He collects 4 butterflies for every moth.
Hence, the ratio of
Butterflies : Moth
4 : 1
Sum of the proportion = 4 + 1 = 5
We are also told he has a total of 220 butterflies and moths.
Hence:
The number of butterflies he collects is calculated as
4/5 × 220 = 176 butterflies
The number of moth that he collects =
1/5 × 220 = 44 moth
