Answer:
y = 37
Step-by-step explanation:
the 3 angles lie on a straight line and sum to 180°
sum the 3 angles and equate to 180
y + 29 + 40 + 2y = 180 , that is
3y + 69 = 180 ( subtract 69 from both sides )
3y = 111 ( divide both sides by 3 )
y = 37

Answer:
x=5
Step-by-step explanation:
An isosceles trapezoid has two pairs of congruent base angles. This means angle F has to equal angle E. So we have 2x^2+21=3x^2-4. Move the variables to one side and we get 25=x^2. Square root both sides and we get two values x=5 and x=-5. Since angles cannot necessarily be negative, we only want the positive value. In this case x=5.

Answer:
2.5
Step-by-step explanation:
Add up the 5s of the left side first and you will get 25. Then you add up the 5s on the otherside and you will get 10. Subtract the 10 from the 25 to get 15. Finally, divide 15 by 6 to get the weight of each triangle, 2.5
1: 5 x 5 = 25
2: 5 x 2 = 10
3: 25 - 10 = 15
4: 15/6 = 2.5
The weight of each triangle is 2.5
Have an amazing day!
PLEASE RATE!!
Answer: 2.5
Step-by-step explanation:
What we know:
Both sides need to be equal, and one side already has a constant defined value.
That value is 25 (units)
How to solve:
By using a simple algebraic equation, we can find the value of a triangle's weight. X will represent a square's weight, and y will represent a triangle's weight.
Process:
Set up equation 5x = 2x + 6y
Substitute 5(5) = 2(5) + 6y
Simplify 25 = 10 + 6y
Cancel out -10 -10
15 = 6y
Separate variable /6 /6
Solve 2.5 = y
Solution: y (triangle weight) = 2.5
You can check this by adding 2.5 6 times (15) to 5 2 times (10). This will equal 25, which would balance out the other side

[tex]\begin{gathered}\\\implies\quad \sf lwh = V \\\end{gathered} [/tex]
Since w and h are multiplying l , when they will be transposed to other side of equation, they will divide V and thus be in denominator.

Regarding control charts, changing from two-sigma limits to three-sigma limits: A. decreases the probability that the process average will change. B. increases the probability of concluding nothing has changed, when in fact it has. C. decreases the probability that defects will be generated by the process. D. does not change the probability of making type I or type II errors. E. increases the probability of searching for a cause when none exists.
Changing from Two-sigma limits to three-sigma limits helps to reduce the probability that defects will be generated by the process. Hence the correct answer is C.
What is a Two-Sigma Limit?
This is used to refer to the inclusion of about ninety-five percent of data plotted on the normal distribution curve.
Three sigma-limit on the other hand is a statistical calculation where data fall within three standard deviations from a mean.
If in a manufacturing firm, the quality control unit issues out a polity to reject products that are within two standard deviations to their accepted mean, then more errors will be captured thus resulting in a lot of loss or defective products.

10 litres of oil is poured into a container whose cross section is a rectangle with dimensions 40 cm ×25cm .find the height of the container
Answer:
[tex]Volume = \: length \times width \times hight[/tex]
[tex]10 \times 1000 = \: 40cm \times 25cm \times hight[/tex]
[tex]Hight = \frac{10000}{40cm \times 25cm} [/tex]
[tex]Hight = 10cm[/tex]
The height of the container is 10 cm.
Given that, 10 liters of oil is poured into a container whose cross section is a rectangle with dimensions 40 cm ×25cm.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
We know that, 1 liter = 1000 cm³
So, 10 liters = 10000 cm³
Area of the base = 40 × 25 = 1000 cm²
Volume = 1000 × Height
⇒ 1000 × Height=10000
⇒ Height=10 cm
Therefore, the height of the container is 10 cm.

Una compañía de transporte público cobra " "x" " por transportar cierta mercancía 20 kilómetros y " "z" " por transportar la misma mercancía 25 kilómetros. A) Determine la relación entre la tarifa total y la distancia recorrida, suponiendo que es lineal. B) ¿Cuál es la tarifa mínima por transportar esta mercancía? C) ¿Cuál es la cuota por cada kilómetro que la mercancía es transportada?" x = $190. 00 z = $242. 0. Prueba con las sugerencias que aparecen más abajo o introduce una consulta nueva
Utilizando los dos puntos dados, veremos que la relacion lineal es:
A) y = ($10.4 /km)*x -$18A) y = ($10.4 /km)*x -$18B) -$7.6C) $10.4 /km¿Como encontrar la relacion lineal?Una ecuación lineal se escribe como:
y = a*x + b
donde a es la pendiente y b es la ordenada al origen.
Sí sabemos que una linea pasa por los puntos (x₁, y₁) y (x₂, y₂), entonces la pendiente va a ser:
a = (y₂ - y₁)/(x₂ - x₁).
Aca tenemos los dos puntos:
(20km, $190)
(25 km, $242)
Entonces la pendiente será:
a = ($242 - $190)/(25km - 20km) = $10.4 /km
y = ($10.4 /km)*x + b
Para obtener el valor de b, usamos uno de los puntos. Evaluando en x = 20km deberiamos obtener y = $190, entonces:
$190 = ($10.4 /km)*20km + b
$190 = $208 + b
$190 - $208 = b = -$18
Entonces la ecuación es:
y = ($10.4 /km)*x -$18
B) La tarifa minima es lo que obtenemos con x = 1 km, entonces es:
y = ($10.4 /km)*1 km - $18 = -$7.6
Notar que da un valor negativo, lo que indica que la relación quizas no es lineal.
C) La cuota por kilometro es la pendiente de la relación lineal, en este caso será: $10.4 /km.
