- E.
122
Correct Answer
A. -63Explanation
The given expression is solved using the order of operations (PEMDAS/BODMAS). First, we perform the multiplication and division from left to right. 2,5 x 40 equals 100, and 49 divided by 7 equals 7. Then, we perform the addition and subtraction from left to right. 30 minus 100 equals -70, and -70 plus 7 equals -63. Therefore, the answer is -63.Rate this question:

- E.
6842
Correct Answer
B. 6084Explanation
In the given sequence of numbers, each number is obtained by adding the sum of the digits of the previous number to it. For example, 6184 is obtained by adding the sum of digits of 782 (7+8+2=17) to it, resulting in 6184. Similarly, 6084 is obtained by adding the sum of digits of 6184 (6+1+8+4=19) to it, resulting in 6084. This pattern continues for the subsequent numbers in the sequence.Rate this question:

2524
Correct Answer
C. 2652Explanation
To solve this problem, we need to apply the order of operations, which states that we should perform multiplication before subtraction. Therefore, we first calculate 11 multiplied by 44, which equals 484. Then, we subtract 484 from 562, resulting in 78. Hence, the correct answer is 78.Rate this question:

1440 jam + 36 minggu = ... bulan
- A.
10
- B.
11
- C.
12
- D.
14
- E.
15
Correct Answer
B. 11Explanation
The question asks for the sum of 1440 hours and 36 weeks in months. To convert hours to months, we divide by 720 (assuming each month has 30 days, so 30 days * 24 hours = 720 hours). Therefore, 1440 hours is equal to 2 months. To convert weeks to months, we divide by 4 (since there are approximately 4 weeks in a month). Therefore, 36 weeks is equal to 9 months. Adding 2 months and 9 months gives us a total of 11 months.Rate this question:

13 x 6 x 5 = a x 39, nilai a adalah ...
- A.
8
- B.
9
- C.
10
- D.
11
- E.
12
Correct Answer
C. 10Explanation
The given equation is 13 x 6 x 5 = a x 39. To find the value of a, we need to simplify the equation. By multiplying 13, 6, and 5 together, we get 390. So the equation becomes 390 = a x 39. To solve for a, we divide both sides of the equation by 39. This gives us a = 10. Therefore, the value of a is 10.Rate this question:

- E.
10
Correct Answer
D. 12Explanation
The equation (3 x t) - (5 x 3) = 3 x 3 + 12 can be simplified as 3t - 15 = 9 + 12. By adding 15 to both sides of the equation, we get 3t = 36. Dividing both sides by 3, we find that t = 12.Rate this question:

(363 : p) x 32 = 1089
- A.
3
- B.
4
- C.
6
- D.
7
- E.
9
Correct Answer
A. 3Explanation
The given equation is (363 : p) x 32 = 1089. To find the value of p, we need to divide 363 by p and then multiply the result by 32. The result of this calculation should be equal to 1089. By trying different values for p, we find that when p is equal to 9, the equation holds true. Therefore, the correct answer is 9.Rate this question:

If a polynomial P(x) is divided by (x - 3), the remainder is 5. What is the value of P(3)?
- A.
0
- B.
3
- C.
5
- D.
Cannot be determined
Correct Answer
C. 5Explanation
According to the Remainder Theorem, if a polynomial P(x) is divided by (x - a), the remainder is P(a). In this case, the polynomial is divided by (x - 3), and the remainder is 5. Therefore, P(3) = 5. This theorem is useful for quickly finding the value of a polynomial at specific points by knowing the remainder of its division.Rate this question:

- D.

- E.
10.745
Correct Answer
B. 11.745Explanation
The question asks for the total number of seconds when 3 hours, 15 minutes, and 45 seconds are added together. To convert hours to minutes, we multiply by 60, and to convert minutes to seconds, we also multiply by 60. Therefore, 3 hours is equal to 3 * 60 * 60 = 10800 seconds, 15 minutes is equal to 15 * 60 = 900 seconds, and 45 seconds remain the same. Adding these values together gives us a total of 10800 + 900 + 45 = 11745 seconds, which is equal to 11.745 in decimal form.Rate this question:

Correct Answer
D. 16Explanation
Dari gambar di atas, dapat dilihat bahwa penjumlahan semua balok horisontal tepat sama dengan penjumlahan semua balok vertikal. Jika kita menjumlahkan semua balok horisontal, kita mendapatkan hasil 24 + 12 + 18 = 54. Jika kita menjumlahkan semua balok vertikal, kita mendapatkan hasil 20 + 16 + B = 54. Oleh karena itu, nilai B haruslah 16 agar kedua penjumlahan tersebut sama.Rate this question:

![Latihan Terakhir Matematika Prasmul 2020 - Quiz]()
Correct Answer
E.Explanation
Since xy > 0, it means that both x and y have the same sign, either both positive or both negative. Therefore, the statement "x > 0" is definitely true because x must be positive. However, we cannot determine the sign of y based on the given information, so the statement "y < 0" is not necessarily true. Similarly, we cannot determine the relationship between y and x, so the statement "y - x > 0" is not necessarily true either.Rate this question:

Dalam sebuah pertandingan, skor yang bisa di dapatkan adalah 2, 3, dan 7. Suatu tim memperoleh skor total 3528, setelah bermain beberapa kali dan setiap hasillnya dikalikan dengan ketiga macam skor tersebut. Berapa kalikah tim tersebut bermain?
- A.
7
- B.
6
- C.
8
- D.
5
- E.
10
Correct Answer
A. 7Explanation
The answer is 7 because the total score of 3528 can only be achieved by playing 7 times. This is because the possible scores are 2, 3, and 7, and each score is multiplied by the number of times played. If we assume that the team played 7 times, the total score would be 7 x 2 + 7 x 3 + 7 x 7 = 14 + 21 + 49 = 84. Since the total score is 3528, it means that the team played 7 times.Rate this question:

B. 316Explanation
In a leap year, the rambutan tree bears fruit twice, each time for 25 days. Therefore, the total number of days the tree bears fruit in a leap year is 50 days. In a non-leap year, the tree does not bear fruit for the remaining days, which is 365 - 50 = 315 days. Since the question asks for the number of days the tree does not bear fruit, the answer is 316 days.Rate this question:

- D.

- E.
Rp1.750.000
Correct Answer
C. Rp1.620.000Explanation
Kakak membeli dua pasang sepatu wanita seharga masing-masing Rp1.000.000. Karena ini adalah pembelian ke-2 dan seterusnya, maka kakak mendapatkan diskon 20% untuk kedua pasang sepatu tersebut. Diskon ini akan mengurangi harga total sebesar 20% x Rp2.000.000 = Rp400.000. Setelah dikurangi diskon, harga total menjadi Rp2.000.000 - Rp400.000 = Rp1.600.000. Selanjutnya, karena total belanja kakak melebihi Rp1.000.000, kakak juga mendapatkan diskon 10% untuk total belanja. Diskon ini akan mengurangi harga total sebesar 10% x Rp1.600.000 = Rp160.000. Setelah dikurangi diskon, harga total menjadi Rp1.600.000 - Rp160.000 = Rp1.440.000. Namun, kakak membayar secara nontunai, sehingga dikenakan biaya tambahan 10% x Rp1.440.000 = Rp144.000. Jadi, nominal belanja kakak setelah diskon adalah Rp1.440.000 + Rp144.000 = Rp1.584.000.Rate this question:
