Based on the weight of the plastic to the weight of the paper, the ratio of plastic to paper in the simplest form is 6 : 1

To find the ratio of plastic to paper, there is a need to convert the weights such that they have the same units.

Assuming we convert the plastics to grams, the number of grams of plastic would be:

= 3 kg x 1,000 grams per kg

= 3,000 grams

The ratio then would be:

3,000 grams of plastic   : 500 grams of paper

To get to the simplest form, divide both sides by 500:

3,000 / 500 : 500 / 500

6 : 1

The x- and y-intercepts of the graph of x + y = 18 both have the values of 18

The x-intercept of the function is the point or points where the graph of the function crosses the x-axis i.e. the point where the function equals 0

The equation of the graph is given as

x + y = 18

To calculate the x-intercept, we set the value of y to 0

This is represented as

y = 0

So, we have the following equation

x + 0 = 18

Evaluate the like terms

x = 18

To calculate the y-intercept, we set the value of x to 0

This is represented as

The measure of x, m∠DEG, m∠GEF  and m∠DEF will be 5,112°,68°and 180° respectively.

When two lines or rays converge at the same point, the measurement between them is called an "Angle."

It is given that,

m∠DEG = (23x-3)°

m∠GEF = (12x+8)°

As m∠DEF is a straight angle its angle measurement is 180

As a result,

m∠DEF=m∠DEG+m∠GEF

180°=m∠DEG+m∠GEF

Put the given values

180°=(23x-3)°+(12x+8)°

180=35x+5

35x=180-5

35x=175

x=5

Substitute the value of x to obtain all the angles as

m∠DEG=(23x-3)°

m∠DEG=(23(5)-3)°

m∠DEG=112°

For m∠GEF,

m∠GEF=(12x+8)°

substitute the value of x

m∠GEF=(12(5)+8)°

m∠GEF=68°

Thus, the measure of x, m∠DEG, m∠GEF  and m∠DEF will be 5,112°,68°and 180° respectively.

Proportionately, based on Marvin's initial deposit, Victor invested Php 40,000 in the partnership.

Proportion is like a ratio that shows a numerical relationship between two variables.

Proportions equate one ratio to a value.

For instance, we can equate Marvin's investment ratio to his investment.

This equation helps us to calculate the total investment made by the four partners in the small business.

                               Jamie   Ralph   Marvin          Victor   Sum of Ratio

Investment ratio         8:         3:           12:                2           25

Investment amount    ?           ?     Php 240,000    ?            ?

Marvin investment = Php 240,000 = 12/25

Total investment by the partners = Php 500,000 (Php 240,000/12 x 25)

Victor's investment = Php 40,000 (Php 500,000 x 2/25)

Answer:

y = 4x -80

Step-by-step explanation:

We need the slope and the y intercept.

The y intercept is -80.  This is where the line crosses the y axis.

The slope is the change in y over the change in x.  

Let's go from point (0,-80) the y intercept the the point that cross the x axis (20,0)  Start at -80, how many units to you go up until you are at the same level as point (20,0)? 80 units.  Now, from (0,0) how many units do you go right to get to (20,0)? 20.

We end up go 80 unit up and 20 units right, this would be written [tex]\frac{80}{20}[/tex] Which simplifies to 4.  This is our slope.

Slope (m) = 4

y intercept (b)= -80  Plug those into

y = mx + b

y = 4x -80

After using substitution method - The new height of the painting will be 247cm.

What is the substitution method?

To solve many simultaneous linear equations, use the substitution method in algebra. As implied by the name, this strategy involves replacing a variable's value from one equation with another.

we are given the original width of the painting to be 6cm and the original height to be 19cm.

after enlarging the size of the painting the new and enlarged width becomes 78cm

and we assume the new and enlarged height of the painting to be xcm.

we now the ratios

original height : original width = enlarged height : enlarged width ,

will remain equal,

Hence substituting the numerical values in the ratios we get

If there is no solution to a compound inequality, it can involve AND.

A sentence having two inequality statements connected by the words "or" or "and" is referred to as a compound inequality. The conjunction "and" denotes the equal validity of both statements in the compound sentence. The conjunction "or" means that the entire compound sentence is true as long as either of the two statements is true.

The term "OR" can help us find more solutions, whereas the phrase "AND" can help us find less solutions. As a result, we can create a compound inequality with no solution by using "AND."

2x=108

Step-by-step explanation: This is the equation because when it says twice a number, you are multiplying a number two times. In this case, the number is not given, so x is the variable being multiplied two times. If the number was 8, it would look like this: 2(8)=108. Of course this isn't true, but to find the actual answer you would divide two on both sides of the equation. This is so that both of the two's cancel out on the left side of the equation. and the variable is left on that side. Our goal is to isolate the variable. In these types of equations, our goal is to isolate the variable and find what the variable is worth. If we do 108 divided by 2 that gives us 54. Since there was x left on the left side of the equation and there is 108 left on the right side we have our equation. x=54

10 pounds of food each chicken eat last week.

This is a problem from an algebraic equation. We can solve this problem by following a few steps.

Each chicken eats the same amount of food, as per the question. Let's assume there is x number of chickens.

Therefore, if each chicken eats the same amount of food then the total food required for all chickens is, (x × x) = x² pound.

Again, Mrs. Rollins bought 100 pounds of chicken food.

Hence x² is equivalent to 100 pounds. We can generate an equation from this. Which is,

x² = 100

Or, √x² = √100         [ root both sides ]

Or, x = 10

Now, we can conclude that there are 10 chickens and each chicken eats 10 pounds of food in a week.

A percentage (from Latin: per centum, "by a hundred") is a quantity or ratio stated as a fraction of 100 in mathematics. The percent symbol, "%," is commonly used, however the abbreviations "pct.", "pct," and sometimes "pc" are also used. A % is a non - dimensional (pure) quantity; it does not have a unit of measurement. In the context of sports statistics, the term "%" is frequently used incorrectly since the referred figure is stated as a decimal proportion, not a percentage. Similarly, a team's winning percentage, or the fraction of matches won, is commonly reported as a decimal proportion; a team with a.500 winning percentage has won 50% of its matches.

The quadratic function that models the path of the second kick is given by:

y = -2/125(x - 25)² + 10.

The equation of a quadratic function, of vertex (h,k), is given by the following rule:

y = a(x - h)² + k

In which the coefficients are explained as follows:

For the first kick, the equation is:

y = -1/40(x - 25)² + 15.

Meaning that the ball reached a maximum height of yards after an horizontal distance of 25 yards.

For the second kick, the horizontal distance is the same, but the maximum height if 5 yards less, that is, of 10 yards, hence the vertex is:

(h,k) = (25, 10).

Hence the equation is:

y = a(x - 25)² + 10.

After 50 yards, the ball hits the ground, hence the leading coefficient a is found as follows:

0 = a(50 - 25)² + 10

625a = -10

a = -10/625

a = -2/125

Hence:

y = -2/125(x - 25)² + 10.

The domain of the relation as given in the task content; (x,y): y = x(x-3) / (x+4)(x-7) is the set of all real number values except; -4 and 7 and hence is represented as; { x : x R, x ≠ -4, x ≠ 7}.

It follows from the task content that the domain of the relation given in the task content be determined.

On this note, since the domain of a relation or function simply refers to the set of all possible input values of such function.

Since the relation in this scenario is a rational function, it follows that the domain is the set of all real number values except that which renders the relation undefined.

Therefore, since the values which render the relation undefined, render the denominator equal to 0; we have;

(x+4)(x-7) = 0.

x = -4 OR x = 7.

Ultimately, the domain of the relation is the set of all real numbers except; x = -4 and x = 7.
