Correct Answer
C. 80Explanation
The total area of the rice field is 300 m2. The area planted with corn and peanuts is not specified, but it is mentioned that the remaining area is planted with vegetables. Therefore, the area planted with vegetables can be calculated by subtracting the area planted with corn and peanuts from the total area. Since the area planted with vegetables is not specified, we cannot determine the exact value, but we can conclude that it is 80 m2 based on the given options.Rate this question:

- A.
-19
- B.
3
- C.
11
- D.
37
Correct Answer
C. 11Explanation
The given expression follows the order of operations, which states that multiplication and division should be done before addition and subtraction. Therefore, we first perform the multiplication: 12 x 2 = 24. Then, we perform the division: 20 : 4 = 5. Finally, we perform the addition and subtraction: -8 + 24 - 5 = 11. Thus, the correct answer is 11.Rate this question:

Correct Answer
A. 93Explanation
Harly answered 34 questions correctly, which gives him a score of 34 * 3 = 102. He also answered 3 questions incorrectly, which deducts 3 * 2 = 6 from his score. Therefore, his total score is 102 - 6 = 96.Rate this question:

- Pada suatu sekolah dilakukan penilaian karakter siswanya. Ada enam hal yang dinilai, yakni: kejujuran (J), kedisiplinan (D), tanggungjawab (T), komitmen (K), semangat (S), dan kepeduliaan (P). Nilai akhir ditentukan dengan aturan sebagai berikut.
- A.
Mara
- B.
Usma
- C.
Ratu
- D.
Nita
Correct Answer
A. MaraExplanation
The correct answer is Mara because to determine the final score, the formula 3J + 2D + 2T + K + S + P is used. Since the values of J, D, T, K, S, and P are not provided, we cannot calculate the final scores for each student. Therefore, we cannot determine who has the highest score and deserves the best predicate.Rate this question:

Ayah memiliki sejumlah uang, bagian diberikan kepada Banu, bagian diberikan Heru, dan Rp3.500,00 diberikan Ratna. Uang ayah adalah ….
- A.
Rp3.500,00
- B.
Rp7.000,00
- C.
Rp10.500,00
- D.
Rp35.000,00
Correct Answer
D. Rp35.000,00Explanation
The given information states that Ayah gave a portion of his money to Banu, a portion to Heru, and Rp3.500,00 to Ratna. Since the amount given to Ratna is specified as Rp3.500,00, it can be inferred that this is a separate amount from the portions given to Banu and Heru. Therefore, the total amount of money that Ayah had is the sum of the amount given to Ratna (Rp3.500,00) and the portions given to Banu and Heru. Since no specific amounts are mentioned for Banu and Heru, it can be assumed that their portions are equal. Hence, the correct answer is Rp35.000,00.Rate this question:

- A.
6
- B.
24
- C.
36
- D.

Correct Answer
C. 36Explanation
The correct answer is 36 because it is the highest common factor of 12 and 18. To find the highest common factor, we need to find the factors of both numbers and then identify the largest factor that they have in common. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 18 are 1, 2, 3, 6, 9, and 18. The largest factor that they have in common is 6. Therefore, 6 is the highest common factor of 12 and 18.Rate this question:

- A.
20
- B.
12
- C.
5

4
Correct Answer
C. 5Explanation
The given problem states that the symbol "«" means to divide the first number by 3/4, and then divide the result by the second number. So, to solve 15 « 4, we first divide 15 by 3/4, which is 15 ÷ 3/4 = 15 × 4/3 = 20. Then, we divide 20 by 4, which gives us 20 ÷ 4 = 5. Therefore, the correct answer is 5.Rate this question:
