Berapakah banyaknya bilangan ganjil yang terdiri dari 3 angka? tolong jelaskan caranya!
Bilangan ganjil yang terdiri dari 3 angka adalah
101, 103, 105, 107, ... , 999 dan termasuk barisan aritmetika dengan a = 101 dan b - 2 jadi rumusnya
Un = a + (n-1)b
999 = 101 + (n-1)2
999 = 101 + 2n - 2
999 = 99 + 2n
2n = 900
n = 450
Jadi banyaknya bilangan ganjil yang terdiri dari 3 angka ada 450

sebenarnya kita yang bergerak kan , ato awan,, kalo awan gerak awan menuju kemana? makasih
Awan bergerak akibat terhembus angin, jadi arahnya juga menyesuaikan dengan arah angin. Hal demikian terjadi juga pada awan dan mendung, sehingga sering kita jumpai suatu tempat terjadi hujan lebat sedangkan tempat sebelahnya tidak hujan.

when we use present perfect?and when we use past perfect?are there any differences between that tenses?
Tentu saja ada perbedaan.
Present Perfect Tense POLA:Subject + Have + Verb 3 + …. Has |
Tense ini digunakan untuk menyatakan bahwa selalu ada hubungan antara peristiwa masa lampau dengan saat kini.
1. Untuk membicarakan pengalaman di masa lampau, kita tidak menekankan lebih pada “kapan” kita melakukan itu, tetapi ingin menegaskan apakah kita telah melakukannya.
Contoh:
I have seen ET.
He has lived in Bangkok.
Have you been there?
We have never eaten caviar.
I have bought a car. | ||
| past | present | future |
| - | + | |
| Last week I didn't have a car. | Now I have a car. |
John has broken his leg. | ||
| past | present | future |
| + | - | |
| Yesterday John had a good leg. | Now he has a bad leg. |
Has the price gone up? | ||
| past | present | future |
| + | - | |
| Was the price $1.50 yesterday? | Is the price $1.70 today? |
The police have arrested the killer. | ||
| past | present | future |
| - | + | |
| Yesterday the killer was free. | Now he is in prison. |
I have worked here since June. | ||||||||
| past | present | future | ||||||
| The situation started in the past. | It continues up to now. | (It will probably continue into the future.) |
“The past perfect tense”
menyatakan kegiatan pada waktu lampau sebelum adanya peristiwa di masa lampau. Jadi semacam peristiwa lalu di masa lalu.
Contoh:
The train had left when we arrived. | ||||||
| past | present | future | ||||
| Train leaves in past at 9am. | ||||||
| ||||||
| We arrive in past at 9.15am. |
past perfect tense | present perfect tense | |||||
| had | done | > | | have | done | > | | |||||
| past | now | future | past | now | future |
kasi tau contoh fable dund
A fox fell into a well and couldn’t get out. By and by a thirsty goat came along. Seeing the fox in the well it asked if the water was good. “Good”, said the fox “It’s the best water I’ve tasted in all my life. Come down and try it yourself.”
The goat was thirsty so he got into the well. When he had drunk enough, he looked around but there was no way to get out. Then the fox said, “I have a good idea. You stand on your hind legs and put your forelegs against the side of the well. Then I’ll climb on your back, from there. I’ll step on your horns, and I can get out. And when I’m out, I’ll help you out of the well.”
The goat did as he was asked and the fox got on his back and climbed out of the well. Then he coolly walked away. The goat called out loudly after him and reminded him of his promise to help him out. The fox merely turned to him and said; “If you only had thought carefully about getting out, you wouldn’t have jumped into the well.”
The goat felt very sad. He called out loudly. An old man walking nearby heard him and put a plank into the well. The goat got out and thanked the old man.
Once upon a time, a rabbit wanted to cross a river but he could not swim. He had an idea. He saw a boss of crocodile swimming in the river. The rabbit asked the boss of crocodile, “How many crocodiles are there in the river?” the boss of crocodile answered, “We are twenty here.” “Where are they?” the rabbit asked for the second time. “What is it for?” the boss of crocodile asked.
“All of you are good, nice, gentle, and kind, so I want to make a line in order. Later I will know how kind you are,” said the rabbit. Then, the boss of crocodile called all his friends and asked them to make a line in order from one side to other side of the river. Just then, the rabbit started to count while jumping from one crocodile to another; one… two… three… four…. Until twenty, and finally, he thanked all crocodiles because he had crossed the river.
