Pak/Ibu, terima kasih sekali atas jawaban utk pertanyaan saya ini. Sangat membantu sekali.

Bpk/Ibu menjawab pertanyaan saya ini jika yg benar adalah yg B. Mohon penjelasannya Pak/Bu karena saya tidak paham dengan bacaan ini. Apa yg dimaksud dng hardcore environmentalist, Pak/Bu?

Which statement is NOT TRUE according to the text?

            a.   Stop polluting air with your car.

            b.   Stop establishing green house for research. 

            c.   Stop throwing your rubbish away to your environment.

            d.   Keep your environment clean from rubbish.

           

HOW TO STOP THE GLOBAL WARMING

      Let’s keep it simple.

                  First, everything I tell you is going to be realistic and          genuinely        useful. So I won’t tell you to give up your car – though     I may offer you some suggestions for how you can reduce ITS impact on         the environment. I may make some product or service       recommendations along the way, but all of them will provide a               benefit to the environment and be the best, most useful things you can do.

                  Second, this isn’t a new issue – remember when The           Greenhouse Effect was so big in the news? Now the buzzwords are the climate change, carbon trading, carbon footprint and            carbon neutral – more about that later though.

                  Then, let me just say this, I’m no hardcore   environmentalist. In fact, until recently I didn’t do much more than       separate the recycling from the rest of my rubbish! I’m now             determined to do whatever I can to AT LEAST reduce my personal impact on the environment.

     

karena pernyataan B tidak didukung oleh text atau tidak berdasarkan text.

hardcore   environmentalist adalah ahli lingkungan.

SALAM, saya mempunyai beberapa soal yang saya rasa rumit saat saya mengerjakan entah kurang mengerti akan sifat atau kalimatnya... tolong pembahasannya

1. himpunan dari SPL

a.  0,5x + 0,3y + 0,2z = 46

     0,2x-0,5y+0,4z= 0

     0,1x+0,8y-0,6z=26

2.  a.x 2+y2-6x+4y-12=0

        3y-4x-7=0

      b. 2x-y=3

          x2 -y2=0

 

3. titik A dan titik B adalah titik potong yg dibentuk perpotongan antara parabola y=ax2+x+4 dan garis y=2x+a. jika titikA terletak pada sumbu Y,maka tentukan koordinat B

4. suatu bilangan terdiri p,q,r. jmlah ketiganya 16. jk jumlah bil pertama dan kedua=bil ketiga dikurangi 2, nilai bil itu= 21 kali jumlah ketiga bilangannya kemudian ditambah 13. tentukan 3 bil itu.(untuk soal ini saya masih mentok di R, saya kerjakan r=9)

5. ini yang saya rasa paling susah, himp penyelesaian dari 25x+y=(0,25)x-y+1/2

dan (x-y)=1/3log5+3log2

 

tolong pembahasannya khususnya no 4 dan 5..

terimakasih Ibu/Bapak

kenapaya?

kalau kita jemur pakaian ditempat yang terlalu panas bisa membuat warnanya bertambah pudar?

Pudarnya warna pakaian yang dijemur dibawah terik matahari adalah karena pengaruh sinar UV yang memiliki efek kimia, salah satu tandanya adalah memudarnya warna pakaian. Oleh karena itu tidak dianjurkan menjemur pakaian (terutama yang berwarna - warni) secara langsung dibawah terik matahari.

(Maaf, besuk lagi silahkan menulis pertanyaan pada kelas 9 ya, salam dari Pak Arief dan Pak Herman)

Terima kasih, Pak/Bu sudah menjawab pertanyaan saya. Namun saya masih bingung dengan jawaban yg ini.

 

Have you ever seen a shooting star? A bright light          streaks across the sky. It looks like a star falling to Earth. It’s       actually a meteor.

                  A shooting star is a piece of rock or metal. There are           billions of chunks of rock and metal scattered throughout the solar      system. Most are as small as grains of sand, but the largest are   many miles across. A piece of rock and metal floating through          space is called an asteroid.

                  Sometimes asteroids come close to Earth. They fall             through Earth’s atmosphere, the air around the planet. Earth’s atmosphere “rubs” against the rock. The rubbing makes the rock           so hot that it glows. The glowing rock is called a meteor.

                  Most meteors burn up before they hit the ground. All that’s left of them is specks of dust. Others are so big that they make it      through the atmosphere and crash into Earth. A meteor that hits             the ground is called a meteorite.

                  Meteorites can make big holes in the ground called craters. There are not many meteorite craters on Earth. Other planets, such       as Mercury and Mars, have many more craters. Those planets   don’t have thick atmospheres, so most meteors that fall toward    them make it all the way to the ground. There are also lots of     meteorite craters on our Moon and on the moons of other planets.

 1.      The following statements are TRUE based on the text, except ……………      a.   A meteor that hits the ground is called a meteorite.      b.   The Moon has lots of craters because it has thin atmosphere.      c.   A piece of rock and metal floating through space is called an asteroid.      d.   Big holes in the ground caused by the hit of meteors are called                      craters.

 

Jawaban yg benar dr Bpk/Ibu adalah yg B karena bulan tidak punya atmosphere. Tolong Pak/Bu di bagian mana dari bacaan tersebut yang menunjukkan kalau bulan tidak punya atmosphere dan bagaimana hubungannya karena saya masih tidak mengerti. Mohon penjelasannya. Terima kasih.

justru tidak ada keterangan di text nya tersebut maka itulah yang benar

At a hotel in the resort town of Vevey, Switzerland, a young American named Winterbourne meets a rich, pretty American girl named Daisy Miller, who is traveling around Europe with her mother and her younger brother, Randolph. Winterbourne, who has lived in Geneva most of his life, is both charmed and mystified by Daisy, who is less proper than the European girls he has encountered. She seems wonderfully spontaneous, if a little crass and “uncultivated.”

            Despite the fact that Mrs. Costello, his aunt, strongly disapproves of the Millers and flatly refuses to be introduced to Daisy, Winterbourne spends time with Daisy at Vevey and even accompanies her, unchaperoned, to Chillon Castle, a famous local tourist attraction. The following winter, Winterbourne goes to Rome, knowing Daisy will be there, and is distressed to learn from his aunt that she has taken up with a number of well-known fortune hunters and become the talk of the town. She has one suitor in particular; a handsome Italian named Mr. Giovanelli, of uncertain background, whose conduct with Daisy mystifies Winterbourne and scandalizes the American community in Rome. Among those scandalized is Mrs. Walker, who is at the center of Rome’s fashionable society.

           Both Mrs. Walker and Winterbourne attempt to warn Daisy about the effect her behavior is having on her reputation, but she refuses to listen. As Daisy spends increasingly more time with Mr. Giovanelli, Winterbourne begins to have doubts about her character and how to interpret her behavior. He also becomes uncertain about the nature of Daisy’s relationship with Mr. Giovanellli. Sometimes Daisy tells him they are engaged, and other times she tells him they are not.

            One night, on his way home from a dinner party, Winterbourne passes the Coliseum and decides to look at it by moonlight, braving the bad night air that is unknown to cause “Roman fever,” which is malaria. He finds Daisy and Mr. Giovanelli there and immediately comes to the conclusion that she is too lacking in self-respect to bother about. Winterbourne is still concerned for Daisy’s health, however, and he reproaches Giovanelli and urges him to get her safely home.

            A few days later, Daisy becomes gravely ill, and she dies soon after. Before dying, she gives her mother a message to pass on to Winterbourne that indicates that she cared what he thought about her after all. At the time, he does not understand it, but a year later, still thinking about Daisy, he tells his aunt that he made a great mistake and has lived in Europe too long. Nevertheless, he returns to Geneva and his former life.

1.      Hasan mempunyai beberapa mobil (beroda empat) dan beberapa bajaj (beroda tiga). Suatu hari Hasan menghitung jumlah semua mobil dan bajajnya. Jika terdapat 21 roda, maka Hasan mempunyai bajaj sebanyak …

Selamat jumpa..

Dari soal diketahui ada 2 jenis kendaraan masing masing beroda 3 dan 4, dan jumlah rodanya= 21 buah

Misal banyaknya mobil = p , dan banyaknya bajaj = q didapat persamaan 4p + 3q = 21

dan p > 0 dan q > 0 , p dan q anggota himpunan bilangan bulat positif.

bila p = 1 maka 4p + 3q = 21

                       4.1 + 3q = 21

                        4   + 3q = 21

                                3q = 21 - 4

                                3q = 17

                                  q = 5 2/3  ( tidak mungkin jumlah kendaraan bilangan pecahan)

bila p= 2 maka 4p + 3q = 21

                        4.2 + 3q = 21

                           8 + 3q = 21

                                  3q = 13

                                     q= 4 1/3 ( tidak mungkin )

bila p= 3 maka 4p + 3q = 21

                        4.3 + 3q = 21

                         12 + 3q = 21

                                  3q = 9

                                    q = 3   berarti p= banyak mobil 3 buah dan q = banyak bajaj =3 buah.

bila p = 4 maka 4p + 3q = 21

                         4.4 + 3q = 21

                         16  + 3q = 21

                                  3q = 5

                                    q = 1 2/5 ( tak mungkin )

Jadi banyak bajaj ada 3 buah.

Selamat belajar.
