The cost of Adult ticket is $ 4 and Cost of Children ticket is $ 3.

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, whereas B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason.

The cost of adult ticket be x and child ticket be y respectively.

Now as per sum ,

(i) 5x + 13y = 59 and,

(ii) 5x + 9y = 47

Subtracting equation (ii) from (i) we get,

13y - 9y = 59 - 47

⇒ 4y = 12

⇒ y = 3

putting y = 3 in equation (ii) we get

5x + 9*3 = 47      ⇒ x = 20/5 = 4

When the length, breadth, and height are provided as 8 inches, 7.5 inches, and 6 inches, respectively, the rectangular prism's total surface area is 360 inches2.

Surface area is a measure of how much space an object's surface takes up overall. The total area of a three-dimensional shape's surroundings is its surface area. Surface area refers to the total surface area of a three-dimensional shape. You may compute the surface area of a cuboid with six rectangular faces by adding together their individual areas. Alternatively, you can use the following formula to name the box's dimensions: Surface (SA) = 2lh plus 2lw plus 2hw. A three-dimensional shape's surface area is calculated as the total amount of space it occupies (a three-dimensional shape is a shape that has height, width, and depth).

1. Begin by setting up an equation. Let x be the number of hours worked.

2. 8 hours x 12 days = 96 hours

3. We want to finish the job in 10 days, so 10x = 96

4. Solve for x. 10x = 96, x = 9.6

5. Since we can't work partial hours, round up to 10 hours. Therefore, the man must work 10 hours a day to complete the job in 10 days.

To finish the job in 10 days, the man must work for a total of 100 hours. This means he must work for 10 hours a day to complete the job in the allotted time.

To solve the problem, we must first find the slope of the line containing (4, -2) and (x, -6). The slope of a line is calculated as the change in y-coordinates divided by the change in x-coordinates, or (y2 - y1) / (x2 - x1). In this case, the slope of the line containing (4, -2) and (x, -6) is (-6 - (-2)) / (x - 4) = -4 / (x - 4)

Since the line containing (4, -2) and (x,-6) is perpendicular to the line containing (-2,-9) and (3,-4), we know that the product of the slopes of these two lines is -1. We can use that information to find the slope of the second line: -1 = (-4 / (x - 4)) * m, where m is the slope of the second line. Solving for m, we get m = -1 / (-4 / (x - 4)) = (x - 4) / 4.

We can now use the point-slope form of a linear equation to find the equation of the line containing (-2,-9) and (3,-4). The point-slope form is y - y1 = m(x - x1). In this case, we can use (-2,-9) as (x1, y1) and (x - 4) / 4 as m:

y - (-9) = (x - 4) / 4 * (x + 2)

Simplifying we get y = (x-4)/4 + (-9) = (x-4)/4 - 9

Now we can substitute x = -2 and y = -9 to check if it belongs to this line:

-9 = (-2 - 4)/4 - 9

-9 = -2/4 - 9

-9 = -0.5 - 9

-9 = -9.5

It match so this line is the correct one.

The value of x that satisfies the given conditions is x = -2

You can graph this line on a separate sheet of paper by plotting the point (-2, -9) and using the slope (x-4)/4 to find additional points on the line.

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

The exponential function is an important mathematical function which is of the form

f(x) = [tex]a^x[/tex]

Where a>0 and a is not equal to 1.

x is any real number.

If the variable is negative, the function is undefined for -1 < x < 1.

Here,

“x” is a variable

“a” is a constant, which is the base of the function.

The examples of exponential functions are:

f(x) = [tex]2^x[/tex]

f(x) = 1/ [tex]2^x[/tex] = [tex]2^-x[/tex]

f(x) =[tex]2^(x+3)[/tex]

Answer:

the answer to your question is 3.

Bianca will earn interest of $382.5 for a period of 3years.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same.

Simple interest is calculated with the following formula:

S.I. = P × R × T,

where P = Principal, R = Rate of Interest in % per annum, and T = Time

Given,

Principal P = $3000

Rate of interest R = 4.25% = 4.25/100 = 0.0425

Time T = 3 years

Simple interest S.I. = P × R × T

                               = 3000 × 0.0425 × 3

                               = 127.5 × 3

                       S.I.   = $382.5

Step-by-step explanation:

The angle m∠7 corresponds to angle m∠3 which is vertically opposite the angle m∠1, and so the measure of the angle m∠7 = 118°

angles m∠1 and m∠3 are vertically opposite angles and are said to be equal so;

m∠1 = m∠3 = 6x - 20

angles m∠3 and m∠7 are corresponding angles and are said to be equal so;

m∠3 = m∠7 = 6x - 20

angles m∠7 and m∠8 lie on a straight line so;

6x - 20 + 4x - 30 = 180°

10x - 50° = 180°

10x = 180° + 50° {collect like terms}

10x = 230°

x = 230°/10 {divide through by 10}

x = 23

Therefore since the value of x is 23, then the measure of the angle m∠7 = 6(23) - 20, which result to 118°

Answer: 7 and 1/2

Step-by-step explanation:

When dividing a fraction by a whole number you could turn the whole number into a fraction:

5 = 5/1

Once you turn the whole number into a fraction you then do the keep, change, flip, method

you would keep 5/1 as it is and change the divide sign to the multiplication sign the flip 2/3 to 3/2:

5/1 x 3/2

then you just multiply across

5/1 x 3/2 = 15/2

and 15/2 could be simplified to 7 and 1/2

15/12 is the right representation of  5 divided by 2/3 as a fraction.

To divide a number by a fraction, you can multiply the number by the reciprocal of the fraction. In this case, to divide 5 by 2/3, you can multiply 5 by the reciprocal of 2/3.

Reciprocal of 2/3 = 3/2

So, 5 divided by 2/3 can be written as:

5 * (3/2)

To simplify this, you multiply the numerators together and the denominators together:

(5 * 3) / (2 * 1) = 15/2

Therefore, 5 divided by 2/3 is equal to 15/2 as a fraction.

The perimeter of the rectangle, given that the rectangle has an area of 40 ft² and a length of 8 ft is 26 ft

We'll begin by obtaining the width of the rectangle. The width of the rectangle can be obtained as follow:

Area = Length × Width

40 = 8 × Width

Divide both sides by 8

Width = 40 / 8

Width = 5 ft

Finally, we shall determine the perimeter of the rectangle. Details below:

Perimeter = 2(Lenght + Width)

Perimeter = 2(8 + 5)

Perimeter = 2(13)

Perimeter = 26 ft

Answer: A vertical line has an undefined slope, so we cannot use the slope-intercept form (y = mx + b) to write the equation of the line. Instead, we can use the point-slope form (y - y1 = m(x - x1)) where the slope m is undefined and we have a point (x1,y1) on the line.

Since the line goes through the point (8,4), we can use the point (8,4) in the point-slope form:

y - 4 = undefined(x - 8)

We can simplify this equation by dropping the undefined slope and replacing it with a variable:

y = kx + b

Where k is the slope and b is the y-intercept.

The equation of the vertical line that goes through the point (8,4) is x = 8

It's worth noting that the x-coordinate of a vertical line doesn't change, thus it's equal to a constant value and the equation for a vertical line is of the form x=k where k is a constant.

Answer:

x = 8
