Answer:

1400ft²

Step-by-step explanation:

Given

Room Dimension: 20 ft by 25 ft by 10 ft

Where Length = 20 ft

Width = 25 ft

Height = 10 ft

Required

Surface area of painted walls and ceiling

We'll assume that the room is rectangular in shape and all 4 sides are covered.

This means that Mickey will paint 4 walls and 1 ceiling.

The dimension of the 2 of the 4  walls is as follows;

20ft by 10ft, 25ft by 10ft,

Because opposite sides of a rectangle are equal, the dimension of the remaining 2 walls is: 20ft by 10ft, 25ft by 10ft

Calculating the area of the 4 walls;

[tex]Area = 20ft * 10ft + 25ft * 10ft + 20ft * 10ft + 25ft * 10ft[/tex]

[tex]Area = 200ft^2 + 250ft^2 + 200ft^2 + 250ft^2[/tex]

[tex]Area = 900ft^2[/tex]

The dimension of the ceiling is as follows:

20ft by 25ft

Calculating the area of the ceiling

[tex]Area = 20ft * 25ft[/tex]

[tex]Area = 500ft^2[/tex]

So, the area Micky will cover = Area of 4 walls + Area of ceiling

Total Surface Area [tex]= 900ft^2 +500ft^2[/tex]

Total Surface Area = [tex]1400ft^2[/tex]

Hence, Micky will cover 1400ft²

Answer:

14

Step-by-step explanation:

5x = 70

x = 14

Answer:

The answer is option 1.

Step-by-step explanation:

Given that total angles in a quadrilateral is 360°. So in order to find x, you have to substract the remaining angles from 360° :

[tex]5x + 110 + 110 + 70 = 360[/tex]

[tex]5x + 290 = 360[/tex]

[tex]5x = 360 - 290[/tex]

[tex]5x = 70[/tex]

[tex]x = 70 \div 5[/tex]

[tex]x = 14[/tex]

Answer:

2827 cubic centimetre

Step-by-step explanation:

The cup is cylindrical in shape and it is full to the top.

The height of the cup is 15 cm and its diameter is 8 cm (radius = 4 cm).

The volume of a cylinder is given as:

[tex]V = \pi r^2h[/tex]

where r = radius

h = height

The volume of the liquid in the cup is:

[tex]V = \pi * 15^2 * 4[/tex]

V = 2827.43 cubic centimetre ≅ 2827 cubic centimetre

Answer:

D

Step-by-step explanation:

Answer:

25 percent

Step-by-step explanation:

Total months: 12

Months read more than three books: 3

3/12=25 percent

Answer:

1/4 = 25%.

Step-by-step explanation:

To figure out the percent of months in which she read more than 3 books, we need to figure out how many times she read more than 3 books.

According to the table, she read more than 3 books exactly 3 times: 4, 5, 5.

We also know that there is a total of 12 months. Out of the 12 total months, she read more than 3 books 3 times. So we can say that:

3/12 = 1/4 = 25% of the months she read more than 3 books.

Answer: not clear

Step-by-step explanation:

Answer:

1) Reflection in the x-axis

A' = (-2, -3)

2) Rotation of 180° clockwise about the origin

A'' = (2, 3)

3) Translation of 3 units down and 4 units to the right

A''' = (6, 0)

Step-by-step explanation:

The transformations are as follows;

1) Reflection in the x-axis

Here the x-coordinate is the same and the y-coordinate changes sign.

Therefore, we have;

A (-2, 3)

After reflection in the x-axis becomes A' = (-2, -3)

2) Rotation of 180° clockwise about the origin

When, a point (x, y) is rotated 180° clockwise about the origin, it becomes (-x, -y)

Therefore, we have;

A' = (-2, -3) becomes A'' = (2, 3)

3) Translation of 3 units down and 4 units to the right

Translation of 3 units down and 4 units to the right = [tex]T_{(4, -3)[/tex]

Which gives

A''' = (2 + 4, 3 - 3) = (6, 0).

Answer:

(x,y)  --->  (x - 3, y + 5).

Step-by-step explanation:

The x coordinates are moved 3 to the left (negative) and the y coordinates are moved 5 units up (positive y).

Answer:

17

Step-by-step explanation:

Let the number of 2 point shots be t.

Let the number of 3 point shots be h.

Allison made 87 shots and scored 191 total points. This implies two things:

t + h = 87 ________(1)

2t + 3h = 191 ______(2)

Let us eliminate t by multiplying (1) by 2 and subtracting from (2):

=> 2t + 3h = 191

 -  2t + 2h = 174

               h  = 17

Therefore, she made 17 three point shots.

Step-by-step explanation:

Therefore,

(x+20) + (x-10) + (2x-30) = 180° (Sum of interior angles of a triangle)

Or, x+x+2x+20-10-30 = 180°

Or, 4x-20 = 180°

Or, 4x= 180+20

Or, 4x= 200°

Or, x= 200°/4

Therefore, x= 50°

So,

(x+20)

= 50+20

=70°

(x-10)

= 50-10

40°

(2x-30)

= 2×50-30

=100-30

=70°

If he drank 2 liter every day, you could solve this the following ways...

2+2+2+2+2+2+2=14 because 2 liter every day for 7 days

7 x 2  because there are 7 days in a week, and he drank 2 liters a day, so 7 x 2 would work.

Given That

To cover a distance of 240km, a car has to increase the speed by 5km/hr to reach in time. If the time lost was 40 minutes during traffic jam, find the original speed of the car.

                                  .

increased speed of car = 5km/hr .....(speed 1st)

distance travelled = 240km

speed = distance travelled / time taken

= 240 / 40

= 6

thus,

speed = 6km/hr .....(speed 2nd)

.

therefore original speed

= speed 2nd - speed 1st

= 6-5

= 1

Answer: 1/3

Step-by-step explanation: Using Radical Properties, Whenever we have two or more radical terms which are multiplied with same index, then we can put only one radical and multiply the terms inside the radical.

[tex]\sqrt{ \frac{5}{x^2} }\times \sqrt{ \frac{x^2}{45} }=\sqrt{ \frac{5x^2}{45x^2} }=\sqrt{ \frac{1}{9} }=\frac{1}{3}[/tex]

The expression √(5/x²).√(x²/45) is equivalent to 1/3.

An expression is combination of variables, numbers and operators.

The given expression is √(5/x²).√(x²/45)

Square root of five by x square times square root of x square by forty five

√(5/x²).√(x²/45)

√(5x²/45x²)

Cancel out the x² in the numerator and denominator

√(5/45)

Divide numerator and denominator by 5

√(1/9)

1/3

Hence,  the expression √(5/x²).√(x²/45) is equivalent to 1/3.

Hola!

Las variables aleatorias pueden Cualitativas o cuantitativas.

Las variables aleatorias cualitativas son aquellas que se refieren a atributos o características de los individuos o unidades de interés que no son cuantificables. Dentro de estas variables se pueden identificar dos tipos:

Ordinales: estas variables representan cierto tipo de cualidad que tiene un orden natural, por ejemplo: Opinión de una persona sobre una película de estreno, calificada en "muy buena", "buena", "regular", "mala", "muy mala"

Estas calificaciones son claramente cualidades, pero tienen un orden, todo el mundo sabe que una calificación "regular" es mejor que una "muy mala" y a su vez peor que una calificación "buena"

Nominales: Son aquellas que indican atributos no cuantificables que no tienen un orden natural. Por ejemplo, color de cabello, raza, sexo.  

Las variables aleatorias cuantitativas son aquellas que registran valores numéricos, dicho de manera coloquial: "cuentan cosas". Estas variables siempre toman valores dentro de un rango o intervalo de definición, teniendo esto en cuenta podemos definir dos tipos de variables aleatorias cuantitativas:

Continuas: pueden tomar cualquier valor dentro del intervalo de definición de la variable, por ejemplo, la estatura, el peso, la temperatura, entre un valor y otro existen infinita cantidad de valores que la variable puede tomar. En muchos casos, esto está restringido a la precisión de los métodos utilizados para tomar las mediciones.  

Por ejemplo, una balanza puede tomar pesos de kilogramo a kilogramo, ej: 20kg, 21kg, 22kg mientras que una más precisa puede tomar pesos intermedios de los mismos objetos, ej: 20.1kg, 21.5kg, 22.9kg y otra más precisa puede indicar mediciones más exactas, ej: 20.142kg, 21.538kg, 22.973kg es decir que, cuanto más precisa la balanza que usemos para obtener las mediciones, mayor será la gama de valores que puede tomar la variable.

Discretas: solo pueden tomar ciertos valores dentro del intervalo de definición de la variable aleatoria, a diferencia de las variables continuas, entre los valores posibles que pueden tomar estas variables, no se encuentra nada, es decir que "saltan" de valor en valor. Por esto también se las llama variables discontinuas.

Uno de los ejemplos más comunes de variable discreta es hacer rodar un dado de 6 caras, la variable puede tomar valores 1, 2, 3, 4, 5, 6 pero no puede tomar valores entre esos valores, es decir, el dado nunca va a mostrar valores intermedios como "2.5" o "3.3".

Dicho esto pasemos a identificar el tipo de cada ejemplo:

a) y c) Calidad del producto

Esta es algo engañosa, porque todo depende de la escala determinada para medir la calidad.

Es decir, si la escala de medición de la calidad de un objeto es de 0 a 10, siendo cero lo peor y 10 lo mejor, entonces la variable es cuantitativa discreta.

Sin embargo, si la escala es nominal, por ejemplo: Alto, medio, bajo, entonces la variable es cualitativa y como las categorías tienen un orden natural, no solo es cualitativa, sino que también es ordinal.

b) y d) Tiempo de publicidad

Esta variable aleatoria "cuenta el tiempo", toma valores numéricos con lo cual es cuantitativa y, además, puede tomar cualquier valor dentro del intervalo de definición, todo depende de la precisión del reloj utilizado lo que la califica como variable continua.
