Answer:
Step-by-step explanation:
If the company wants to just break even, that means that the cost to produce 150 guitars is equal to the price they charge to make a 0 profit. The cost of 150 guitars is
C(150) = 100(150) + 56000 and
C(150) = 71000. That's how much it costs to produce 150 guitars. If they want to make nothing at all, they have to sell the 150 guitars for
p(x) = 71000/150 so
p(x) = 473.33 or 474
Answer:
473.33 units
Step-by-step explanation:
The breakeven point is the level of production at which the costs of production equal the revenues for a product. So, considering P the price of a guitar unit, we have that:
C(150) = 150.P
P = C(150)/150
P = (100.150 + 56000) / 150
P = (15000 + 56000) / 150
P = 71000/150
P ~ 473.33 units of currency per guitar
Which expression is equivalent to the product of 5x + 1 and 2x - 3?
Answer:
10x^2 - 13x - 3
Step-by-step explanation:
(5x + 1)(2x - 3) = 10x^2 - 15x + 2x - 3 = 10x^2 - 13x - 3

Which equation represents the parabola shown on the graph?
y2 = 1.5x
x2 = 1.5y
y2 = 6x
x2 = 6y
The equation represents the parabola is x² = 6y.
What is Equation of Parabola?Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. The topic of conic sections includes parabola, and all of its principles are discussed here.
The general equation of a parabola is given by y = a(x – h)² + k
We have equations.
The graph's parabola is a vertical parabola that is open vertically and has its vertex at the origin.
So, the equation of the parabola is equal to
x² = 4ay...............(1)
and, the equation of the directrix is y= -a.
her, the directrix is y= -1.5
Now, the equation for the parabola is
x² = 4(1.5)y
x² = 6y

La pirámide egipcia de keops tiene un volumen de 2;574,466 metros cúbicos su base es de 230m ¿cuál es la altura de dicha pirámide?
Answer:
Según los datos brindados, la altura de la pirámide egipcia de Keops sería de:
146 metros aproximadamente.Step-by-step explanation:
Para resolver el ejercicio, debes conocer la fórmula para calcular el volumen de una pirámide cuadrangular, el cual es el tipo de pirámide al cual pertenece la pirámide de Keops:
Volumen de una pirámide cuadrangular = [tex]\frac{L^{2} * h}{3}[/tex]Donde:
L = Longitud de los lados de la base cuadrada.h = Altura de la pirámide.Como queremos identificar la altura, despejamos esa variable de la ecuación, pero para simplificar un poco, vamos a escribir el volumen de la pirámide con la variable "v":
[tex]v=\frac{L^{2} * h}{3}[/tex] [tex]v * 3=L^{2} * h}[/tex] [tex]\frac{v*3}{L^{2} }=h[/tex]Y en esta ecuación que despejamos, procedemos a reemplazar los valores de volumen y base que nos dieron en el ejercicio:
[tex]\frac{2574466m^{3} *3}{(230m)^{2} }=h[/tex]Y realizamos las operaciones correspondientes:
[tex]\frac{7723398m^{3}}{52900m^{2} }=h[/tex] (Como hay metros cúbicos en el dividendo y metros cuadrados en el divisor, simplificamos en el siguiente paso para que solo queden metros).[tex]h = 145.9999622m[/tex]Aproximamos el número al entero más cercano, por lo tanto, la altura de dicha pirámide con los datos dados sería de aproximadamente 146 metros.
Một ô tô đi trong 3¾ giờ đầu với vận tốc 45km/ giờ .Trong 2 giờ tiếp theo đi được 84,7 km. Hỏi ô tô đã đi được tất cả bao nhiêu km?
Answer:
Total distance cover by car = 253.45 km (Approx.)
Step-by-step explanation:
Given:
Speed of car = 45 km/h for 3¾ hour
Distance cover in next 2 hour = 84.7 km
Find:
Total distance cover by car
Computation:
Distance = Speed x time
Distance cover by car = 45 x 3¾
Distance cover by car = 168.75 km
Total distance cover by car = Distance cover by car + Distance cover in next 2 hour
Total distance cover by car = 168.75 + 84.7
Total distance cover by car = 253.45 km (Approx.)

John finds that there is a scholarship available to all personals scoring in the top 5% on the ACT test. If the mean score on the ACT is 21 with a standard deviation of 4.7, what score does he need in order to qualify for the scholarship
Answer:
He needs a score of 28.7315 to qualify for the scholarship
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean score on the ACT is 21 with a standard deviation of 4.7
This means that [tex]\mu = 21, \sigma = 4.7[/tex]
What score does he need in order to qualify for the scholarship?
The top 5%, so the 100 - 5 = 95th percentile, which is X when Z has a p-value of 0.95, so X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 21}{4.7}[/tex]
[tex]X - 21 = 4.7*1.645[/tex]
[tex]X = 28.7315[/tex]
He needs a score of 28.7315 to qualify for the scholarship

The picture of the question is attached.
Answer:
x = 90°
Step-by-step explanation:
Using the identity
cos²x = 1 - sin²x
Given
cos²x - sin x + 1 = 0
1 - sin²x - sin x + 1 = 0
- sin²x - sin x + 2 = 0 ← quadratic equation in sin x ( multiply through by - 1 )
sin²x + sin x - 2 = 0 ← in standard form
(sinx + 2)(sinx - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
sinx + 2 = 0 ⇒ sinx = - 2 ← has no solution as - 1 ≤ x ≤ 1
sinx - 1 = 0 ⇒ sinx = 1 ⇒ x = 90°
solution is x = 90°

An isosceles triangle always has three interior angles that measure 60° each.
Is it true or false?
Please give real answers with explanation. 100 points + I will give brainliest. No Docs/No Files/No Links only answer with explanation.
Answer:
False
Step-by-step explanation:
The definition given is that of an equilateral triangle, NOT that of an isosceles triangle. An isosceles triangle has at least two angles that are equal by definiton. They need not be 60 degrees. For example, a triangle with angle measures of 140, 20, and 20 is an isosceles triangle because two of the angles are equal. Hope this helped!
Mrs Roberts makes 'regular' and 'low-sugar' jam.
She sells both kinds of jam in 340-gram jars.
55% of the weight of her 'regular' jam is sugar.
What weight of sugar is there in a 340-gram jar?
Answer:
187 gram
Step-by-step explanation:
Regular jam = low sugar jam = 340-gram jars
55% of the weight of her 'regular' jam is sugar.
What weight of sugar is there in a 340-gram jar?
Weight of sugar in a 340-gram jar of regular jam = 55% of 340
= 55/100 × 340
= 0.55 × 340
= 187
Weight of sugar in a 340-gram jar of regular jam = 187 gram

Is the missing side length a leg or the hypotenuse?
Answer:
the missing side is
[tex] \sqrt{9 {}^{2} + 12 {}^{2} } = 15 \: yards[/tex]
Answer: Hypotenuse
Step-by-step explanation:
This is a right triangle because it has a right angle, and the longest side of a right triangle is the Hypotenuse. The question mark in this image is asking about the longest side of this triangle, so therefore, it is the hypotenuse, not a leg.

Determina las Medidas de Centralización (Media, Mediana y Moda) y las medidas de Dispersión (Desviación media y Desviación estándar).
necesito ayuda
Respuesta:
Media = 6
Mediana = 6
Modo = 6
Desviación media = 1
Desviación estándar = 1.317
Explicación paso a paso:
Dados los datos:
5, 5, 8, 4, 6, 6, 7, 5, 6, 7, 4, 8, 6, 5, 6, 8
Datos reorganizados: 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 8, 8, 8
La media: Σx / n = 96/16 = 6
El modo, = 6 (valor más alto que ocurre en los datos, valor de datos con la frecuencia más alta)
La mediana = 1/2 (n + 1) ésimo término
Mediana = 1/2 (17) término = 8.5 th término = (6 + 6) / 2 = 6
La desviación media = Σ (x - media) / n
Usando la calculadora, la desviación media = 1
La desviación estándar = √ (Σ (x - media) ² / n-1)
Desviación estándar = 1.317
a right triangle whose acute angles have measures 5x and 4x.
Answer:
x=10
50 and 40
Step-by-step explanation:
The sum of the angles of triangle is 180
90 +5x+4x = 180
Combine like terms
90 +9x =180
Subtract 90 from each side
9x = 180-90
9x = 90
x = 90/9
x = 10
The angles are 5x = 5*10 =50 and 4x = 4(10)= 40
Solve for x.
