-30

• C.

35

• D.

-35

D. -35
Explanation
To find the value of n, we need to solve the equation 75 + 20 - n = 135. By rearranging the equation, we can isolate n by subtracting 75 and 20 from both sides, which gives us -n = 40. To solve for n, we need to multiply both sides of the equation by -1, resulting in n = -40. Therefore, the correct answer to replace the letter n in the given calculation is -35.

• B.

20° c

• C.

15° c

• D.

16° c

D. 16° c
Explanation
The initial room temperature is 18°C. During the day, the temperature increases by 5°C, so it becomes 18°C + 5°C = 23°C. At night, the temperature decreases by 7°C, so it becomes 23°C - 7°C = 16°C. Therefore, the final room temperature is 16°C.

### Bu Santi membeli 15 pak permen coklat, ia memberikan 3 pak kepada anaknya. Sisanya dibagikan kepada 10 tetangganya. Jika setiap pak berisi 85 permen. Maka jumlah permen yang diterima setiap tetangga adalah ....

• A.

102 permen

• B.

98 permen

• C.

75 permen

• D.

125 permen

A. 102 permen
Explanation
Santi bought 15 packs of chocolate candies and gave 3 packs to her child. The remaining packs were distributed among 10 neighbors. Since each pack contains 85 candies, the total number of candies is 15 x 85 = 1275. After giving 3 packs to her child, there are 15 - 3 = 12 packs left. Each neighbor will receive 12 / 10 = 1.2 packs of candies. Since it is not possible to distribute 0.2 of a pack, each neighbor will receive 1 pack, which contains 85 candies. Therefore, each neighbor will receive a total of 1 x 85 = 85 candies.

### Suhu suatu ruangan awalnya adalah –5° C. Suhu ruangan itu dinaikkan 3° C setiap setengah jam. Setelah 4 jam maka suhu ruangan tersebut menjadi ....

• A.

29° C

• B.

24° C

• C.

19° C

• D.

7° C

C. 19° C
Explanation
The initial temperature of the room is -5°C. The temperature of the room increases by 3°C every half an hour. To find the final temperature after 4 hours, we need to calculate the number of half-hour intervals in 4 hours, which is 8 intervals. Multiplying the temperature increase per interval (3°C) by the number of intervals (8), we get a total temperature increase of 24°C. Adding this to the initial temperature (-5°C), we get a final temperature of 19°C.

• A.

328

• B.

-328

• C.

388

• D.

-388

D. -388
Explanation
The given expression involves adding the cubes of 6, 5, and 9 and then subtracting the cube of 9. When we calculate 6^3, we get 216. Similarly, 5^3 is equal to 125. And 9^3 is equal to 729. So, the expression becomes 216 + 125 - 729. Adding 216 and 125 gives us 341. Subtracting 729 from 341 gives us -388. Therefore, the correct answer is -388.

C. 90
Explanation
The correct answer is 90 because KPK stands for "Kelipatan Persekutuan Terkecil" in Indonesian, which translates to "Least Common Multiple" in English. To find the least common multiple of 5, 9, and 6, we need to find the smallest number that is divisible by all three numbers. The prime factorization of 5 is 5, of 9 is 3^2, and of 6 is 2 * 3. Taking the highest power of each prime factor, we get 5 * 3^2 = 45. Therefore, the least common multiple of 5, 9, and 6 is 45.

A. 16
Explanation
The correct answer is 16 because 16 is the highest common factor of 32, 64, and 80. To find the highest common factor (HCF) or greatest common divisor (GCD) of these numbers, we can list their factors and find the largest number that divides all three numbers without leaving a remainder. The factors of 32 are 1, 2, 4, 8, 16, and 32. The factors of 64 are 1, 2, 4, 8, 16, 32, and 64. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The largest number that appears in all three lists is 16, so it is the HCF or GCD.
