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]

What is the value of x?
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]

A book sold 32100 copies in its first month of release. Suppose this represents 6.2% of the number of copies sold to date. How many copies have sold to date.
Answer:
1900 copies sold to date
Step-by-step explanation:
you need to find the value of 6.2% of 32100
To do this:
6.2 ÷ 100
= 0.062
0.062 x 32100
= 1990.2

Triangle ABC is represented by the drawing below.
What are the measures of the interior angles of ABC?
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°

The triangle ABC goes through a series of transformations, resulting in the triangle A’B’C’. The three transformations are listed below. Reflection in the x- axis. Followed by a rotation of 1800 clockwise about the origin Followed by a translation 3 units down and 4 units to the right For triangle ABC, the vertex A is originally located at (-2, 3). Show the new coordinates of A after each of the three transformations above.
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).

Allison plays basketball and last season she made a total of 87 shots (two- or three- point shots). Her points total was 191. How many three-points shots did she make
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.

An object’s weight on Earth varies directly to its weight on the Moon. If a man weighs 180 kg on Earth, then he will weigh 30 kg on the Moon. Set up an algebraic equation that expresses the weight on Earth in terms of the weight on the Moon and use it to determine the weight of a woman on the Moon if she weighs 120 kg on Earth.
Answer:
The gravity of the Moon is about one sixth that of the Earth. For example, an astronaut weighing 180 pounds on the Earth would weigh about 30 pounds on the Moon.
A room is 20 feet by 25 feet with a 10-foot ceiling. If Mickey paints the walls and the ceiling, how much surface area will he cover? Think, What area ISN'T Micky covering and subtract out that area...
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:
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.

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.
Answer:
Step-by-step explanation:
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
Ans. thus, the original speed of the car is 1km/hr.What is the answer to the math problem 6+(-3)

Answer:
Step-by-step explanation:
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.
Espero que tengas un buen días!
