Answer:
A) 140
B) 75
C) 80
D) 20
E) 80
Step-by-step explanation:
Para resolver este problema debemos construir un diabrama de Venn y llenarlo según los datos que se nos brindan.
Comenzamos nombrando cada círculo:
E= personas que usan máquinas eléctricas
M= personas que usan máquinas mecánicas
C = personas que usan computadoras.
- Luego llenamos el área central con un 20, el cual representa las personas que usan los 3 tipos de maquinas.
- En la parte exterior del diagrama de Venn colocamos un 60 por las personas que no usan ninguna de las máquinas.
- En la intersección entre M y C restamos:
25-20=5
Entonces colocamos este 5 en esa región.
- En la intersección entre E y C restamos:
35-20=15
Entonces colocamos este 15 en esa región.
- En la intersección entre E y M restamos:
40-20=20
Entonces colocamos este 20 en esa región.
- En la región de E restamos:
110-20-20-15=55
Entonces colocamos este 55 en esa región.
- En la región de M restamos:
50-20-20-5=5
Entonces colocamos este 5 en esa región.
- En la región de C restamos:
60-15-20-5=20
Entonces colocamos este 20 en esa región.
Y obtenemos el diagrama de Venn que representa esta encuesta (Ver figura adjunta)
Y ahora ya lo podemos usar para responder a las preguntas:
A) Número de personas que no usan computadora. Sumamos los números fuera del círculo C:
55+20+5+60=140
B) Número de personas que usan una máquina eléctrica pero no computadora: Sumamos los números dentro del círculo E con excepción de los números compartidos por el círculo C y obtenemos:
55+20=75
C) Número de personas que usan solo un equipo: Sumamos los números no compartidos en los círculos E, M y C
55+20+5=80
D) Número de personas que usan máquina mecánica y eléctrica pero no computadora: Usamos el número compartido entre E y M que no son compartidos con C
20
E) Sumamos el número que se encuentra solo en C y los que están afuera del diagrama:
20´60=80

The most appropriate statement is that C. The shaded area represent both 2/3 and 6/9 of the whole shape.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Given a square.
This square is divided in to 9 equal sized squares, with 3 rows and 3 columns.
Out of the 9 equal sized squares, 6 squares are shaded.
We can write the fraction of shaded squares to total number of squares as 6/9.
In the same way, we have in the question that, 6 squares which are shaded is the squares in the first two columns, where each column has three squares.
So we can say that, out of 3 equal sized columns, two columns are shaded.
Fraction of shaded columns to total columns is 2/3.
So 2/3 = 6/9.
Hence shaded area represent both 2/3 and 6/9 of the whole shape.

The volume of a rectangular prism whose dimensions are binomials with integer coefficients is modeled by the function V(x) = x^3 − 14x^2 + 49x − 36. Given that x − 1 and x − 9 are two of the dimensions, find the missing dimension of the prism.
Answer:
The missing dimension of the prism is (x-4)
Step-by-step explanation:
Here, we want to find the missing dimensions of the prism
To get the volume, we are to multiply three dimensions since we are talking about volume
Mathematically, to find the third dimension, we need to divide the original polynomial by the product of the two other dimensions
The product of the two other dimensions is;
(x-1)(x-9) = x^2-9x-x + 9
= x^2-10x+ 9
So we divide;
(x^3-14x^2+49x-36)/(x^2-10x+ 9)
We can use long division to get this
using long division, the answer here is x-4
The volume of a prism is the product of its dimensions.
The missing dimension of the prism is x - 4
The volume function is given as:
\(\mathbf{V(x) = x^3 - 14x^2 + 49x - 36}\)
Let the missing dimension of the prism be y.
So, the volume is calculated using:
\(\mathbf{V(x) = y \times (x - 9) \times (x -1)}\)
Multiply the factors
\(\mathbf{V(x) = y \times ( x^2-9x-x + 9)}\)
\(\mathbf{V(x) = y \times ( x^2-10x + 9)}\)
Equate both expressions of volume
\(\mathbf{y \times ( x^2-10x + 9) = x^3 - 14x^2 + 49x - 36}\)
Make y the subject
\(\mathbf{y = \frac{x^3 - 14x^2 + 49x - 36}{x^2-10x + 9 }}\)
Factor the numerator
\(\mathbf{y = \frac{(x - 4)(x^2-10x + 9 )}{x^2-10x + 9 }}\)
Cancel out common factors
\(\mathbf{y = x - 4}\)
Hence, the missing dimension of the prism is x - 4

Answer:
6,912....
Step-by-step explanation:
6 times 12 times 6 time 4 times 4 = 6,912
Answer:
= 360 ft³
Step-by-step explanation:
Rectangular prism
Volume = length x width x height
V = l x w x h
V = 12 x 6 x 4
V = 288 ft³
Triangular prism
Volume = 1/2 x base x height x length
V = 1/2 x 6 x 4 x 6 ( the width of the rectangular prism is the base of the triangular prism)
V = 1/2 x 144
V = 72 ft³
ADD BOTH VOLUMES
= 288 + 72
= 360 ft³
A gallon is 128oz. An airplane can carry 1,445 gallons of fuel. Write the number of ounces of fuel the plane can carry.
Step-by-step explanation:
one gallon is 128oz.
1445 gallons are how many Oz?
that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"
or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"
it all works with multiplication. it is the ultimate application for multiplication.
that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.
and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.
128 × 1445 = 184,960oz

How do you tell if a log function is increasing or decreasing?
If the derivative of the function is positive, the function is increasing; if the derivative is negative, the function is decreasing.
What is a logarithmic function?
A logarithmic function is a type of mathematical function that expresses the power to which a given number (the base) must be raised in order to produce a certain value. It is typically written in the form: \(f(x) = log_b(x),\) where b is the base of the logarithm.
To determine whether a logarithmic function is increasing or decreasing, you can look at the sign of the derivative of the function. If the derivative is positive, the function is increasing; if the derivative is negative, the function is decreasing.
In the case of logarithmic functions, the derivative of \(f(x) = log_b(x)\) is f'(x) = 1/x*ln(b), which is always positive for x > 0, so the logarithmic function is increasing for any base b.
Hence, if the derivative of the function is positive, the function is increasing; if the derivative is negative, the function is decreasing.

the alexander family and the chen family each used their sprinklers last summer. the water output rate for the alexander family's sprinkler was 30l per hour. the water output rate for the chen family's sprinkler was 40l per hour. the families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 2250l. how long was each sprinkler used?
The Alexander family used their sprinkler for 35 hours, and the Chen family used their sprinkler for 30 hours.
To find out how long each sprinkler was used, we can set up a system of equations. Let's say the Alexander family used their sprinkler for x hours, and the Chen family used their sprinkler for y hours.
From the given information, we know that the water output rate for the Alexander family's sprinkler is 30 liters per hour. Therefore, the total water output from their sprinkler is 30x liters.
Similarly, the water output rate for the Chen family's sprinkler is 40 liters per hour, resulting in a total water output of 40y liters.
Since the combined total water output from both sprinklers is 2250 liters, we can set up the equation 30x + 40y = 2250.
We also know that the families used their sprinklers for a combined total of 65 hours, so we can set up the equation x + y = 65.
Now we can solve this system of equations to find the values of x and y, which represent the number of hours each sprinkler was used.
By solving the equation we get,
The Alexander family used their sprinkler for 35 hours, and the Chen family used their sprinkler for 30 hours.
