Answer 1

Answer:

530.93 OR 530.9

Step-by-step explanation:

Since we know what the radius is 13 we replace R with 13 in the formula form area of a circle. area = [tex]\pi 13^{2}[/tex]

So now we multiply 13 squared or 13 x 13 which equals 169

Now we multiply pi and 169 which gives us 530.929 depending on what number you should round to give  us our answer.

530.93

530.9

2) The school theater has 17 rows of seats. Each row has 53 seats. Which statement explains how to find the closest estimation of the total number of seats in the theater? A) 17 rounds to 10, 53 rounds to 50, and 10 = 50 = 500 seats. B) 17 rounds to 10, 53 rounds to 60, and 10 x 60 = 600 seats. 9. 17 rounds to 20, 53 rounds to 50, and 20: 50 = 1.000 seats. D) 17 rounds to 20, 53, rounds to 60, and 20 x 60 = 1,200 seats.​

Answers

Answer: c.) 17 rounds to 20, 53 rounds to 50, and 20: 50 = 1.000 seats

Step-by-step explanation:

*5 or more, add one more. 4 or less, give it a rest (leave it alone)*

17 rounds to 20

(the 7 is used to boost the 1 to a 2 since its more than 5, making it 20)

53 rounds to 50

(the 3 is less than 4 so we leave the 5 as is, making it 50).

Therefore, 20x50 = 1000 seats or 20:50=1000

A = 14°

Step-by-step explanation:

We can use sine law in this situation, where

[tex]\dfrac{\sin A}{a} =\dfrac{\sin B}{b}[/tex]

where a and b are the lengths of the sides opposite the corresponding angles. From the given diagram, we can see that

[tex]\dfrac{\sin A}{7\:\text{yd}} = \dfrac{\sin 75°}{28\:\text{yd}}[/tex]

or

[tex]\sin A = \dfrac{7}{28}\sin 75° = 0.241[/tex]

Solving for the angle A, we get

[tex]A = \sin^{-1}(0.241) = 14°[/tex]

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

Check first option:

[tex]4a+8[/tex]

Substitute [tex]a=2[/tex]:

[tex]4(2)+8=8+8=16[/tex]

Since 16 is not greater than 16, the first option is incorrect.

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

Check second option:

[tex]2a+a^2[/tex]

Substitute [tex]a=2[/tex]:

[tex]2(2)+2^{2} =4+4=8[/tex]

Since 8 is not greater than 16, the second option is incorrect.

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

Check third option:

[tex]2a+12[/tex]

Substitute [tex]a=2[/tex]:

[tex]2(2)+12=4+12=16[/tex]

Since 16 is not greater than 16, the third option is incorrect.

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

Check fourth option:

[tex]a^4+2[/tex]

Substitute [tex]a=2[/tex]:

[tex]2^4+2=16+2=18[/tex]

Since 18 is greater than 16, the fourth option is correct.

Can somebody do a summary of this?Nearly all people conform to most norms most of the time. People conformbecause through socialisation they have internalised the norms and values oftheir culture. There is a value consensus; nearly all people in a society agree onshared values, and also on the norms derived from them. Even criminals willoften disapprove of the actions of other criminals, which suggests that theyshare part of the overall value system. However, societies need to have ways ofensuring social conformity. All societies have ways of making their membersconform to norms. This is achieved by systems of sanctions. Positive sanctionsare often referred to as rewards and so sanctions usually mean negativesanctions (punishments).Informal social control is exercised by individuals and groups who do nothave any official power to do so. It includes, for example, any way in which youmight express disapproval of something your friends have done that you donot like. You might make a negative comment about them or refuse to speak tothem until they apologise. Informal social control can seem minor but is oftenvery effective. It can be exercised through glares and comments like 'that wasrude or expressions of anger or disgust. One common form of informal social control in peer groups of young people is ostracism or social rejection; that is, anindividual is excluded from the group and made aware that they are not welcome.Some types of informal social control are:shameridiculesarcasmcriticism.When informal social control does not work, then formal social control may beused. This needs to be done by someone who has authority in that situation, suchas a teacher, employer or police officer. Agencies of formal social control includethe police and the criminal justice system. They can impose a wide range of formalsanctions, such as fines and imprisonment.Agencies of social control are also agencies of socialisation. They pass onnorms and values but they are also able to make people conform. The main agenciesof social control are as follows.- Families. It is through primary socialisation in the family that children absorbnorms and values. The strong bonds between parents and children and theimpressionability of young children make this the most important period ofsocialisation. Children learn to regulate their own behaviour so as not to offendothers. They internalise values so that they feel guilt and remorse if they breaknorms that are based on them.- Schools. In the school system children are controlled in many ways. They are toldwhat to do and when, most of the time. Unit 5 explores the idea of the hiddencurriculum, which suggests that at school learning to obey the rules and conform toeducation is as significant for children as learning knowledge and skills.Religion. For those with religious beliefs, religions offer guidelines and laws for howto behave and offer both rewards and punishments for behaviour. The values of asociety are often based on the main religion.The media. The media offer role models as well as constant messages about how tobehave and reminders about rewards and punishments through offering examplesof good and bad behaviour, both in factual news reporting and in fiction.Workplaces. There are rules and regulations at places of work and other norms thatpeople may need to learn as they settle into a new job.- Peer groups. These are powerful agencies of social control because people feelthe need to belong to groups. The threat of being rejected is often a powerfulone. When we feel we have been pushed into behaving in ways that our peers willapprove of, this is called peer pressure.If these agencies fail to control behaviour then societies have more powerfulsanctions. The police and the criminal justice system can be used to enforce laws.Police forces are set up with the explicit purpose of social control. They are able touse coercion (force) when they decide it is necessary. By arresting and chargingpeople the police bring people into the criminal justice system where judges andjuries, acting on behalf of society, have the power to impose sanctions. The range ofsanctions available is discussed in Unit 6 on crime and deviance. In some countriesif it seems that the police are unable to control behaviour the armed forces may beused to do so.
