The GCF of 10, 30, and 50 is 10.

Given numbers are 10, 30, and 50.

To calculate the Greatest Common Factor of the numbers, list the prime factors of each number.

10 = 2 × 5

30 = 3 × 2 × 5

50 = 2 × 5²

GCF is the result of the factors that each of the given numbers has in common.

So, GCF = 2 × 5 = 10

Therefore, 10 is the greatest positive integer that divides 10, 30, and 50 without leaving any remainder.

What is Percent ?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a measurement system.

Given that,

Investment policy pay
PV = $37,000 year;

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

First find the gradient.

Formula of gradient is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2)

Gradient = (-1-(-2))÷(3-(-2))

= (-1+2)÷(3+2)

= 1/5

Equation is y = 1/5 + c

Substitute either one of the points into the equation to find c.

-2 = 1/5(-2) + c

c = -8/5

Hence equation of the line is y = 1/5x - 8/5

The equation of the line that represents Saturn Avenue is; y = 4.

The equation of a line can be ascertained using the formula,

y = mx + c

where m is the line's slope and c is just the y - intercept.

m = vertical change/ horizontal change

m = Δy/Δx

m = (y₂ - y₁)/(x₂ - x₁)

In this question, draw a line through the cleaners as well as perpendicular to Planet Drive.

We can discover the slope of the equation by contemplating two points just on line.

Consider the following points: (8, 4) and (16, 4).

Put the value sin slope.

m = (4 - 4)/(16 - 8)

m = 0/8

m = 0

So we got that,

y - intercept = 4

slope = 0  

Put back the values in equation of line.

y = mx + c

y = (0)x + 4

y = 4

As a result, y = 4 is the equation of the line which represents Saturn Avenue, given that Christopher decides that another road named Saturn Avenue, which will run past this same cleaners and be perpendicular to Planet Drive, is required.

Given:

The 9 litre of 50% acidic liquid.

Required:

What quantity of water should be added to reduce 9 liters of 50% acidic liquid to 30% acidic liquid ?

Explanation:

The solution steps are:

Acidic liquid in 9 liters lotion = (50/100) * 9 = 4.5 liters

Then water = 9 - 4.5 = 4.5 liters

Let 'x' liters be the required quantity of water.

Then :-

[tex]\frac{4.5}{9+x} = \frac{30}{100} = \frac{3}{10}[/tex]

That leads to :-

[tex]3(9+x) = 45 == > 3x = 18[/tex]

Which gives us :-

[tex]x=6[/tex]

The value of x can be calculated using the general form of the equation of parabola,

Here, (p,q) stands for the vertex of the parabola (20,3).

To find the value of a, consider a coordinate (0,0) and substitute the obtained values in the general equation of parabola.

Now, consider the coordinate of the required distance x of the ball, (x,2).

Substitute the above coordinate, the value of a and the vertex in the equation of parabola.

To solve the square on RHS, take square root on both sides of the equation.

Since, the height of 2 m of ball can be obtained at either side of the vertex.

So the distance between the vertex and the required position is

Then, the other possible position of the ball is,

Hence, the height of the ball will be 2m, either at a distance of 8.5m from origin or 31.5m from the origin.

It explains how many times a particular number is composed of another number in a given proportion.

It is also seen as the comparison of two quantities, elements or numbers having the same unit measure. It goes further to explain how much of one of the element or quantity contains another.

This is done on the basis of  their magnitude or sizes.

Explanations:

Dilation is a transformation technique that changes the size of an object in a xy-plane.

From the given figure, there was an enlargement from AJV to A'J'V'. This shows that the scale factor is greater than 1:

Using one of the coordinates V and V'

V = (0, 1)

V' = (0, 4)

Determine the scale factor

Scale factor = V'/V

Scale factor = 4/1

Scale factor = 4

Hence the scale factor of triangle AJV till A'J'V' is 4

The system of linear equations and their solutions are:

1. (51, 26):  x - y = 25; 2x + 3y = 180

2. (-17, -36): x - y = 19; -2x + y/6 = 28

3. (47, 33): 2x - 3y = -5; x + y/11 = 50

4. (-31, -56): 2x - y = -6; x - 305/3 = 2y.

We can solve a system using the substitution method by finding the value of one of the variables, followed by substitution.

1. x - y = 25 -- eqn. 1

2x + 3y = 180 -- eqn. 2

Rewrite eqn. 1:

x = 25 + y

Substitute x = 25 + y into eqn. 2:

2(25 + y) + 3y = 180

50 + 2y + 3y = 180

5y = 180 - 50

5y = 130

y = 26

Substitute y = 26 into eqn. 1:

x - 26 = 25

x = 25 + 26

x = 51

The solution is: (51, 26).

2. x - y = 19 -- eqn. 1

-2x + y/6 = 28 -- eqn. 2

Rewrite eqn. 1:

x - y = 19

x = 19 + y

Substitute x = 19 + y into eqn. 2:

-2(19 + y) + y/6 = 28

-38 - 2y + y/6 = 28

-11y/6 = 28 + 38

-11y/6 = 66

-11y/6 (-6/11)= 66(-6/11)

y = -36

Substitute y = 36 into eqn. 1:

x - y = 19

x - (-36) = 19

x + 36 = 19

x = 19 - 36

x = -17

The solution is: (-17, -36).

3. 2x - 3y = -5 -- eqn. 1

x + y/11 = 50 -- eqn. 2

x + y/11 = 50

x = 50 - y/11

Substitute x = 50 - y/11 into eqn. 1

2(50 - y/11) - 3y = -5

100 - 2y/11 - 3y = -5

-35y/11 = -5 - 100

-35y/11 = -105

-35y/11(-11/35) = -105(-11/35) (multiplication property)

y = 33

Substitute y = 33 into eqn. 2:

x + 33/11 = 50

x + 3 = 50

x + 3 - 3 = 50 - 3

x = 47

The solution is (47, 33).

4. Solving the last one, we will definitely have the solution, (-31, -56).
