Answer:

x = 20°

y = 30

Step-by-step explanation:

The triangle given on close inspection, it is an equilateral triangle.

Each angle in an equilateral triangle is equal. Likewise, each side is equal.

Thus;

16 + y = 46

y = 46 - 16

y = 30

The triangle that has angle 80°, the other complete angle is 60° because it's an angle of an equilateral triangle.

Thus, the smaller angle there is;

180 - (80 + 60) = 40°

Because sum of angles in a triangle is 180°

Now, x + 40 = 60°

Since that's also an angle of an equilateral triangle.

x = 60 - 40

x = 20°

The value of length y is 30 and the value of angle x is 20 degrees and this can be determined by using the properties of an equilateral triangle.

Given :

The triangle ABC is given in the figure.

In an equilateral triangle, all angles are equal and therefore, each side is equal.

16 + y = 46

y = 46 - 16

y = 30

An angle in the triangle is given that is 80 degrees and angle C is 60 degrees because it is an angle of an equilateral triangle.

Applying sum of interior angles property:

80 + 60 + (60 - x) = 180

200 - x = 180

x = [tex]20^\circ[/tex]

[tex]Ratio = 9 :80[/tex]

Step-by-step explanation:

Given

[tex]A_1 = 18ft^2[/tex] --- Area of smaller rectangle

[tex]A_2 = 160ft^2[/tex] --- Area of bigger rectangle

Required

Determine the area of the areas.

The ratio is calculated by the dividing the areas of rectangles.

[tex]Ratio = \frac{A_1}{A_2}[/tex]

Substitute values for A2 and A1

[tex]Ratio = \frac{18ft^2}{160ft^2}[/tex]

[tex]Ratio = \frac{18}{160}[/tex]

Simplify the fraction

[tex]Ratio = \frac{9}{80}[/tex]

Represent as ratio

[tex]Ratio = 9 :80[/tex]

Hence, the ratio of the rectangles is 1 to 9

Answer:

50(1.25p) and 50(0.25p + 1.00)

Step-by-step explanation:

They both equal the same answer.

50(1.25p) = 62.5

50(0.25p + 1.00) = 62.5

when in parentheses, you multiply

50 * 1.25 = 62.5

50 * 0.25 + 1.00 = 62.5

The expression for the given scenario is 50(0.25p+1.00). Therefore, option A and C are the correct answers.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, Mr. Hamilton sponsors the creative writing club.

He went to a local printing shop that charges $0.25 per page in the book and $1.00 to bind the pages together.

The booklet Mr. Hamilton is making has p pages, and he plans to make 50 booklets.

So, the expression is 50(0.25p+1.00)

= 12.50p+50.0

Therefore, option A and C are the correct answers.

Answer:

1/41416353 probability of all five numbers and the mega number matching the winning numbers

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order of the numbers is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Probability of the five numbers matching:

Desired outcomes: 1 -> the matching numbers

Total outcomes: 5 from a set of 47. So

[tex]T = C_{47,5} = \frac{47!}{5!(47-5)!} = 1533939[/tex]

Probability:

[tex]p_{S} = \frac{1}{1533939}[/tex]

Probability of the mega number matching:

1 from a set of 27. So

[tex]p_M = \frac{1}{27}[/tex]

Probability of both matching:

Independent events, so we multiply the probabilities:

[tex]p = p_S*p_M = \frac{1}{1533939}*\frac{1}{27} = \frac{1}{41416353}[/tex]

Plano:

Superficie:

El punto es una entidad que tiene una posición, pero no tiene dimensiones (largo, ancho o alto). Por lo tanto, es de dimensión cero, es decir, adimensional. Contiene el significado de lugar, de existencia, pero no tiene elementos mensurables, es decir, no se puede medir.

En contextos geométricos, una línea es un cuerpo unidimensional de forma y longitud arbitrarias. Todos los objetos unidimensionales, como cuerdas, líneas rectas, mitades y perímetros, son líneas. Se cree que una línea se forma cuando un punto de dimensión cero se mueve en el espacio y forma una línea infinita de múltiples puntos.

Intuitivamente, el concepto de plano se puede describir como una superficie perfectamente recta (es decir, sin curvatura ni cavidad) y lisa, que tiene volumen cero y ocupa solo las dos dimensiones del espacio tridimensional.

La superficie de un objeto se refiere a una superficie bidimensional, que separa el objeto de otros objetos y del entorno. En topología, la superficie es una dimensión bidimensional.
