Which of these quadrilaterals can have two sides with length 8 cm and two sides with length 3 cm? Select all that apply. Rectangle Rhombus Square Parallelogram Trapezoid

Answers

Answer: Rectangle

Rhombus

Parallelogram

Step-by-step explanation:

A rectangle has four sides and the opposite sides are equal.

A rhombus is simply a flat shape that has 4 equal straight sides and the sides have equal length.

A square has all the four sides equal.

A parallelogram is a quadrilateral that has two pairs of parallel sides. It should be noted that the opposite sides of the parallelogram have equal length.

A trapezoid doesn't have two sides with equal lengths. Therefore, the correct answer to the question will be:

• Rectangle

• Rhombus

• Parallelogram

a man has been driving a second hand car for the past four years. over these four years he managed to save 16% as a deposit of the price of the brand new car he wants to buy. the price of the new car is 750 000... calculate the amount he saved for the deposit​

Answers

Answer:

$120,000

Step-by-step explanation:

Provided that  

The price of the new car is $750,000

And, the saving percent is 16%

We need to calculate out the saving amount for the deposit

Therefore, the saving amount is

= $750,000 × 16%

= $120,000

Basically we multiply these two things to each other in order to get the saving amount

Andre currently runs a total of 12 Miles each week. he plans to increase the number of miles he runs each week by a 1.5 miles until he is running a total of 26 miles each week. how many weeks will it take Andre to reach his goal?​

Answers

Answer:

1.5x+12=26

Step-by-step explanation:

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

(5 points) e. Of the following three statements, choose the best option and write a viable argument showing how it is reflected by the Cost Function for Wichita’s factory. (10 points) ___ The electricity contract with the utility company is structured so that higher daily energy usage is charged at a lower rate.___ The plant’s production processes are performed primarily by robots that are able to work longer hours, when needed, at no additional cost.
___Overtime wages were required to produce at levels above 25,000 units.
2. Factory in Seattle Seattle’s factory is the company’s newest. It was constructed with sustainable building techniques and materials, so its cost structure has been affected in several ways. The Seattle plant uses a mix of solar power (not very reliable with so many clouds), thermal power, and wind. It has an array of batteries, so at the beginning of each production day, there is “free” stored energy that can produce up to 8,000 units. Of course, energy is just one factor of the cost of production, but it is significant.
The cost function for the Seattle factory is given by the following piecewise function. That is, ()is the cost function, where is the number of units produced. The plant’s maximum capacity is 42,000 units
per day.
() = { 0.35 ≤ 8,000

Answer:

According to the graph, if only one unit was produced, the cost per unit would be $1.00. In reality, the company would not call in its worker and start up the equipment to produce one unit. What safeguard do you think that many manufacturers use to avoid this type of problem?

The per-unit cost will be as follows,

a) Wichita factory has cost function as more up to 25000 units and less for above 25000 units.

b) Piece wise function for cost per units for production of units can be written as

C(x) = cost per unit, will be as follows,

C(x)=1÷x,0 [tex]\leq[/tex] x [tex]\leq[/tex] 25000,

=0.8÷x, 25000 [tex]\leq[/tex] x [tex]\leq[/tex] 35000,

C) cost per unit for 35000 unit

=C(35000)= 0.8÷35000

= 2.28(10⁻⁵)

What is the cost per unit?

Cost per unit  is referred to the cost of goods sold or the cost of sales, is how much money a company spends on producing one unit of the product they sell.

Thus, the cost per unit will be 2.28(10⁻⁵).

En una compañía se realiza una encuesta a 200 personas, se encontró la siguiente distribución, en el uso de máquinas eléctricas, mecánicas y computadoras: Eléctricas 110, mecánicas 50, computadoras 60. Mecánicas y computadoras 25, eléctricas y computadoras 35, eléctricas y mecánicas 40. Las tres 20 y 60 nada. A) Encuentre el número de personas que o usan computadora. B) Que usen una maquina eléctrica pero no computadora. C) Que usen solo un equipo. D) Que usen mecánica y eléctrica pero no computadora. E) Cuantos no tienen ni maquina eléctrica ni mecánica.

Answers

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

Jaxon is flying a kite, holding his hands a distance of 2.5 feet above the ground and
letting all the kite's string play out. He measures the angle of elevation from his hand
to the kite to be 33. If the string from the kite to his hand is 150 feet long, how many
feet is the kite above the ground? Round your answer to the nearest hundredth of a
foot if necessary

Answers

Answer:

Step-by-step explanation:

As Jaxon holding his hands a distance of 2.5 feet above the ground.

means h1= 2.5 feet

elevation angle from the hand is 33° so ∅=33°

distance of kite from his hand is  150 feet

so from the image we can see , now

as we know that  ,

Sin∅ =h2/150

Sin33°=h2/150

0.55 =h2/150                   (Sin33°= 0.545)

so h2= 81.70 feet

so height from ground is (H)=h1+h2= 2.5+81.70

H=84.20 feet
