Responder:
275 pesos
60.000 pesos
Explicación paso a paso:
Dado que :
Número de piezas = 1000
Precio por pieza = 200
600 piezas vendidas con un beneficio del 25%
(100 + 25)% = 125% de 200
1,25 * 200 = 250 cada uno
Precio de 600:
(600 * 250) = 150 000
Para un beneficio del 30% de todo el lote:
(100 + 30)% = 130% * 200 = 260
(1000 * 260) = 260 000
Precio de los 400 restantes:
(260.000 - 150.000) / 400 = 110.000 / 400 = 275 peso
Beneficio de la venta:
Precio de venta:
(150.000 + 110000) = 260000 pesos
Precio de compra :
(1000 * 200) = 200.000 pesos
260.000 - 200.000 = 60.000 pesos
Determine whether AB and CD are parallel, perpendicular,
or neither.
A (12,3), B(-3,9), C (-6,4), D (-2,-6)
Answer:
Step-by-step explanation:
we can find the equations for both lines and analyze after
[tex]y = mx + b\\where\\m = \frac{y_2-y_1}{x_2-x_1}\\\\[/tex]
AB:
[tex](12, 3), (-3, 9)\\m = \frac{9-3}{-3-12} = \frac{6}{-15} = \frac{-2}{5}[/tex]
[tex]y = \frac{-2}{5}(x) + b\\3= \frac{-2(12)}{5} + b\\3 = \frac{-24}{5} + b\\b = \frac{39}{5} \\y = \frac{-2}{5}(x) + \frac{39}{5}[/tex]
CD:
[tex](-6, 4) (-2, -6)\\m = \frac{4-(-6)}{-6-(-2)} = \frac{10}{-4} = \frac{-5}{2} \\y = \frac{-5}{2}(x) + b\\4 = \frac{-5(-6)}{2} + b\\4 = 15 + b\\b = -11\\y = \frac{-5}{2}(x) - 11[/tex]
Determining whether two lines are parallel or perpendicular involves looking at their slopes. AB has a slope of -2/5, CD has a slope of -5/2. Since these are not equal (not parallel) and not negative reciprocals of each other (not perpendicular), the lines are neither perpendicular or parallel.

88-55+ 5x-7=180
Find the value of x
Answer:
x = 30.8
Step-by-step explanation:
88 - 55 + 5x -7 = 180
33 + 5x -7 = 180
5x -7 = 180 - 33
5x - 7 = 147
5x = 147 +7
5x = 154
x = 154/5
x = 30.8

The arithmetic operation is used to make 60 by the number 2,4,6,8 with operation 6×4×2+8+4=60.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Multiplication, Subtraction, Summation, and division.
As per the given numbers,2,4,6,8
Let's multiply 6 and 4
6 × 4 = 24
Now let's multiply 24 by 2
24 × 2 = 48
So, 6 × 4 × 2 = 48
Now we need to add only 12 to get 60 so, 8 + 4 = 12
So, 6 × 4 × 2 + 8 + 4 = 60
Hence "The arithmetic operation is used to make 60 by the number 2,4,6,8 with operation 6×4×2+8+4=60".

If 5cos^2θ + 6sin^2θ =11/2
, the value of cosecθ =--------
Answer:
[tex]\csc(\theta)=\sqrt{2}[/tex]
Step-by-step explanation:
Please refer to the attachment below.
We have:
[tex]5\cos^2(\theta)+6\sin^2(\theta)=11/2[/tex]
Remember that cosine is the ratio of the adjacent side to the hypotenuse. Therefore:
[tex]\cos(\theta)=\frac{b}{c}[/tex]
And sine is the ratio of the opposite side to the hypotenuse. Therefore:
[tex]\sin(\theta)=\frac{a}{c}[/tex]
Substitute into our original equation:
[tex]5(\frac{b}{c})^2+6(\frac{a}{c})^2=11/2[/tex]
Square:
[tex]\frac{5b^2}{c^2}+\frac{6a^2}{c^2}=\frac{11}{2}[/tex]
Multiply both sides by c squared:
[tex]5b^2+6a^2=\frac{11}{2}c^2[/tex]
Let’s also multiply both sides by 2 to eliminate the fraction:
[tex]10b^2+12a^2=11c^2[/tex]
Remember that according to the Pythagorean Theorem:
[tex]c^2=a^2+b^2[/tex]
Hence, we can make another substitution:
[tex]10b^2+12a^2=11(a^2+b^2)[/tex]
Distribute:
[tex]10b^2+12a^2=11a^2+11b^2[/tex]
Subtract 10b² from both sides:
[tex]12a^2=11a^2+b^2[/tex]
Subtract 11a² from both sides:
[tex]a^2=b^2[/tex]
Take the square root of both sides:
[tex]a=b[/tex]
Hence, a is equivalent to b.
Then, we must have a 45-45-90 Triangle.
Therefore, our angle θ is 45°.
We can substitute this back into our original equation to make sure. Remember that cos(45)=sin(45)=√2/2:
[tex]\begin{aligned} 5\cos^2(45)+6\sin^2(45)&=11/2 \\ 5(\frac{\sqrt{2}}{2}})^2+6(\frac{\sqrt{2}}{2})^2&=11/2 \\ 5(2/4)+6(2/4)&=11/2 \\ 5(1/2)+6(1/2)&=11/2 \\ 5/2+6/2&=11/2 \\ 11/2&=11/2 \;\checkmark \end{aligned} \\[/tex]
Hence:
[tex]\begin{aligned} \sin(45)&=\frac{1}{\sqrt{2}} \\ \Rightarrow \csc(\theta)&=\sqrt{2} \end{aligned}[/tex]

What is Quadratic Equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax²+ bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a≠ 0) for an equation to be a quadratic equation. The x² term is written first when constructing a quadratic equation in standard form, then the x term, and finally the constant term. The numerical values of a, b, and c are often expressed as integral values rather than fractions or decimals.
Given:
Volume of Cuboid= 374
length= 2cm
width= x+ 3
height= x+ 9
Now, Volume of cuboid= length x width x height
2(x+3)(x+9)=374
2(x² + 12x +27)= 374
x² + 12x +27 = 187
x² + 12x -160=0
Now, factorizing
x² + 20x -8x-160=0
x( x+20) -8(x+ 20)=0
(x+ 20)(x - 8)=0
x= 8 and x= - 20
As. the dimensions cannot be negative.
So, Width= x+3 = 8+3 = 11cm
Height= x+9 = 3+9 = 17 cm

A man travels at 42 degrees northwest, and ends up 8.5 miles west of his starting point. How far did he travel?
Answer:
The man traveled 12.70 miles.
Step-by-step explanation:
We can find the distance traveled by the man knowing:
[tex]d_{W}[/tex]: the distance at the west = 8.5 miles
[tex]\theta_{NW}[/tex]: the northwest angle = 42°
Then by using the following trigonometric identity we have:
[tex] sin(\theta) = \frac{d_{W}}{d_{NW}} [/tex]
[tex] d_{NW} = \frac{d_{W}}{sin(\theta)} = \frac{8.5 miles}{sin(42)} = 12.70 miles [/tex]
Therefore, the man traveled 12.70 miles.

72 persons have enough food for 7 days . but after one day they decided to finish the food in 3 remaining days . For if they invited more persons how many persons did they invite?
Answer:
We have been given that
72 persons has enough food for 7days.
After 1 day they decided to finish the food in remaining 3 days.
We need to find number of invitees to finish the food.
After one day there are 72 people and they have food for 6 days.
If people are changed n times, time will change to (1/n) of initial time.
\frac{1}{n}\times 6\ =\ 3n1×6 = 3
Therefore n = 2
Total number of people needed = n × 72
Total number of people needed = 72×2
Total number of people needed = 144
Hence the number of invitees = 144 - 72 =72
72 people are invited to finish the food in 3 days

the sum of two numbers is 31. if one of these numbers is x and x is 11 more than the other number what is the value of x
Answer:
y equals 17
So the larger of the two numbers is 17.
Step-by-step explanation:
So, here is what is given.
x+y=31
2x=y+11
So if x+y=31, then 2x+2y will equal 62. Replace 2x with what's given.
y+11+2y=62
3y+11 -11 =62 -11
3y=51
y=17.
Alternatively
x+y=31, and 2x=y+11
x -x +y=31 -x
y=31-x
2x=31-x+11
2x +x=42-x+x
3x=42
x=14
2(14)=y+11
28 -11 =y+11 -11
Again, y equals 17.
So the larger of the two numbers is 17.

Answer:
area = x(3x +10)
Step-by-step explanation:
The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.
horizontal unmarked = (2x+15) -x = x +15
vertical unmarked = (2x -5) -(x -5) = x
The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.
The whole area is ...
x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)

Which is greater, 4 4/10 or 32/10? Explain how u know.
Answer:
4 4/10
Step-by-step explanation:
Well, 32/10 would by 3 2/10 when you divide it, I think. So 4 4/10 is greater.
Fractions may be equal or unequal.
[tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]
The fractions are given as:
[tex]\mathbf{F_1 = 4\frac{4}{10}}[/tex]
[tex]\mathbf{F_2 = \frac{32}{10}}[/tex]
Express the fractions as improper fractions
[tex]\mathbf{F_1 = \frac{44}{10}}[/tex]
Both fractions have the same denominator.
So, the fraction with a greater numerator is greater.
By comparison: 44 is greater than 32
i.e. 44 > 32
Hence, [tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]
