Para controlar la pandemia, se ha restringido la salida de las personas de sus casas. Esta medida se denomina cuarentena y es una de las principales maneras de disminuir el número de contagios. Las restricciones de salida que se han ido tomando son las siguientes: o • A: En Guayaquil, la primera semana no se podía salir de casa desde las 12h00 hasta las 6h00. • B: En el resto del país, la primera semana no se podía salir de casa desde las 20h00 hasta las 6h00. • C: En todo el país, desde la tercera semana no se puede salir de casa desde las 14h00 hasta la 6h00. • D: Si los casos de contagio siguen en aumento potencial, se pensaría en una restricción de 24 horas. Actividades 1. Representa en forma de intervalo y sobre la recta numérica los 4 casos de restricciones planteados. 2. Resuelve el intervalo correspondiente a las siguientes operaciones: A U B C ∩ D

Answer 1

Answer:

The graphical representation of the intervals as well as the solutions of the operation on the number line can be found in the attachment.

A ∪ B = (0, 6) ∪ (12, 24)

C ∩ D = (0, 6) ∩ (14, 24)

Question:

To control the pandemic, people have been restricted from leaving their homes. This measure is called quarantine and is one of the main ways to decrease the number of infections. The exit restrictions that have been taken are the following: o

• A: In Guayaquil, the first week you could not leave home from 12:00 to 6:00.

• B: In the rest of the country, the first week you could not leave home from 8:00 p.m. to 6:00 a.m.

• C: In the whole country, from the third week onwards you cannot leave the house from 2:00 pm to 6:00 am.

• D: If the cases of contagion continue to increase potentially, a 24-hour restriction would be considered. Activities 1. Represent in the form of an interval and on the number line the 4 cases of restrictions posed.

2. Solve the interval corresponding to the following operations: A∪B; C∩D

Step-by-step explanation:

1. The time in Hours is represented on the number line.

A) Restrictions From 12.00pm until 6.00am

In hours: 0 to 6.00am; 12.00pm to 24.00pm

(0, 6); (12, 24)

B. Restriction from 8.00pm to 6.00am

In hours: 20:00pm to 24.00pm; 0 to 6:00 am

(0, 6); (20, 24)

C. Restriction from 2.00pm to 6.00am

In hours: 14:00pm to 24.00pm; 0 to 6:00am

(0, 6); (14, 24)

D. 24hr restrictions

In hours: 00:00am until 24:00pm

(0, 24)

2. From the graph,

A ∪ B = (0, 6) ∪ (12, 24)

C ∩ D = (0, 6) ∩ (14, 24)

Where '∪' mean the union of A and B. That is, we combine all the element of A and B together.

And '∩' mean the intersection of C and D. That is we pick the values common to C and D.

Shaun is 4 years older than her sister Charmaine. If the sum of their ages is 16 how old is Charmaine?A) 4 years old
B) 6 years old
C) 8 years old
D) 10 years old

Answers

Answer:

The answer is B) 6 years

Step-by-step explanation:

First of all, build an equation. With the given problem, you can come up with:

s + c = 16

In which interprets that both their ages summed up are 16. Secondly,:

s = c + 4

After you will use the typical system of equations to solve. So, plug in the second equation to the first, where s will become c + 4, and the equation is now:

c + 4 + c = 16

And finally, solve for Charmaine's age.

2c + 4 = 16

-4 -4

-----------------

2c = 12

c = 6

Answer:6 years old

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(3) = 27?A. A cube with a volume of 3 cubic feet has side lengths of 27 feet.
B. A cube with side lengths of 3 feet has a volume of 27 cubic feet.
C. 3 sides of the cube have a total length of 27 feet.
D. 3 of these cubes will have a total volume of 27 cubic feet.

Answers

we know that

The volume of a cube is equal to

$V(s)=s^(3)$

where

s is the length side of the cube

In this problem we have

$s= 3\ ft$

The volume is equal to

$V(3)=3^(3)=27\ ft^(3)$

therefore

the answer is the option B

A cube with side lengths of 3 feet has a volume of 27 cubic feet

I think the correct answer from the choices listed above is option B. The best interpretation of the function given as v(3) = 27 would be a cube with side lengths of 3 feet has a volume of 27 cubic feet. Hope this answers the question. Have a nice day.

Approximately 15% of the shirts at windsor and best garment factory are labeled irregular and di not receive the windsor and best label. At this rate how many shirts neef to be made to produce approximately 500 Windsor and Best shirts are not irregular?

Answers

500 is 15% less than the number that need to be made, because 15% of
the number that are made will be irregulars.

Remember that 15% = 0.15

500 = 85% of the number.

500 = 0.85 of the number.

Divide each side by 0.85 :

The number = 500 / 0.85 = 589 shirts
