sin(63°) = 4 / CD

AD = 4.489

Now distinction in lengths of AB and AD = 5.657 - 4.489

                                                                     = 1.168

What is one variable equation?

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For example, 2x+3=8 is a linear equation having a single variable in it.

What is a linear equation in math?A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.

According to given value ;

    Let x = number of clay pots. Since Billy bought 8 pots in total , the                    number of ceramic pots Billy bought is 8-x

    67 =(8 litre )*(x clay pots)+(9 litres)*(8-x);

By solving one variable equation;

Answers

The number of hamburgers sold on Wednesday is 141 and the number of cheeseburgers sold on Wednesday is 423

Although a part of your question is missing, you might be referring to this full question: On Wednesday, a local hamburger shop sold a combined total of 564 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Wednesday?

Total number of burgers sold on Wednesday = 564

Let the number of hamburgers sold on Wednesday be x

Let the number of cheeseburgers sold on Wednesday be y

Formulating the equation we get:

x + y = 564-----(1)

It is also given that, the number of cheeseburgers sold was three times the number of hamburgers. So,

y = 3x

Substituting y = 3x in equation (1) we get

x + 3x =564

4x = 564

x = 141

Putting x = 141 in equation (1) we get

y = 423

So, the number of hamburgers sold is 141 and the number of cheeseburgers sold is 423

For the function h defined as h(x) = nx² + 28, n is a constant and h(3) = 1. What is the value of h(-6) ?​

Answers

Answer:

Step-by-step explanation:

Step One

The first step is to find the value of n.

h(x) = n(x) + 28

h(3) = 1

That means that 1 is on the left and wherever there is an x on the right, it will have a value of 3

Step Two

Substitute values

1 = n(3) + 28                  

Step 3

Solve

1 = 3*n + 28                       Subtract 28 from both sides

1 + - 28 =  3n                     Combine

-27 = 3n                             Divide both sides by 3

-27/3 = 3n/3

- 9 = n

Step 4

Let x = - 6 on the right side of the original equation.

h(-6) = -18 + 28

re 1 1/4 inches each, how many books will fit on one

Answers

Answer:

24 books can fit on 1 shelf.

Step-by-step explanation:

Question: Juan has 28 paperback books that measure 1 and 1/4 inches each. How many books will fit on one shelf if each shelf measures 30 inches?

Step-by-step:

We know that each book is 1 and 1/4 inches each. It might be easier to convert the fraction into a decimal.

1/4 inches is 1 divided by 4 which equals to 0.25 inches

1 inch + 0.25 inches = 1.25 inches

so, 1 and 1/4 inches = 1.25 inches

To find out how many books fit on a shelf, we need to find: length of 1 bookshelf divided by length of 1 book

We know that one bookshelf is 30 inches and 1 book is 1.25 inches

so, 30/1.25 or 30 divided by 1.25 = 24

Therefore, 24 books can fit on 1 shelf.

nineteen over 4 = 19/4 = 4.75

two and one fifth = 2 [tex]\frac{1}{5}[/tex] = 11/5 = 2.2

85% = 85/100 = 0.85

7) In the given figure, PQR is an equilateral triangle with coordinates of Q and
R as (-2, 0) and (2, 0) respectively. Find the coordinates of the vertex P.

Answers

The coordinates of the vertex P is calculated as (0,2√3).

What is defined as the distance formula?

The distances among two points as a characteristic of their coordinates are given by an algebraic expression (like coordinate system).

The Pythagorean theorem is used to derive distance formulae for points in rectangular coordinates in 2- and three-dimensional Euclidean space.Because it has a starting and ending point, a line segment can be graphed in both two-dimensional and three-dimensional coordinate planes.Because of the two-dimensional coordinate plane, the starting and stopping points can also be marked as two-dimensional coordinates (x₁, y₁) and (x₂, y₂), culminating in the distance formula as: d = √(x₂ - x₁)² + (y₂ - y₁)².

Now, according to the given question;

The coordinates of the points Q and R  is given as;

Q and R as (-2, 0) and (2, 0).

Now, as the all three points P,Q and R forms the equilateral triangle. Then, the distance of each side or the distance between two consecutive points are equal.

Calculate the distances between the points;

Distance between Q and R;

QR = √(2 + 2)² + (0 - 0)²

QR = 4

Distance between Q and P;

Let the coordinated of P be (x, y);

Then,

QP = √(x + 2)² + (y + 0)²

QP = QR = 4

4 = √(x + 2)² + (y)²     ........(equation 1)

Distance between R and P;

RP = √(x - 2)² + (y + 0)²

RP = QR = 4

4 = √(x - 2)² + (y)²     ........(equation 2)

Equating equation 1 and 2.

√(x + 2)² + (y)² = √(x - 2)² + (y)²

Squaring both side;

(x + 2)² + (y)² = (x - 2)² + (y)²

x² + 4 - 4x + y² = x² + 4 - 4x + y²

Simplifying the equation;

x = 0.

Put the value of x in equation 1;

4 = √(x + 2)² + (y)²

y = 2√3.

Therefore, the coordinates of the point P are found to be (0, 2√3).

Answers

The coordinates of the image of the point (- 4, 5) is (- 5, 15).

What is the image of a coordinate by using a translation?

In this question we find the coordinates of the original point and the translation vector. Please notice that translations are examples of rigid transformations, meaning that Euclidean distance is conserved in the resulting image. A translation can be done by the following formula:

P'(x, y) = P(x, y) + T(x, y)

Where:

P(x, y) - Original pointT(x, y) - Translation vectorP'(x, y) - Resulting point

If we know that P(x, y) = (- 4, 5) and T(x, y) = (- 1, 10), then the resulting point is:

P'(x, y) = (- 4, 5) + (- 1, 10)

P'(x, y) = (- 5, 15)
