Joni dan Budi tersesat di hutan. Mereka mulai dari titik yang sama. Budi berjalan ke arah Timur dan Joni berjalan ke arah Selatan dengan kecepatan 25% lebih lambat dibandingkan Budi. Setelah 49 menit, Budi sudah berjalan sejauh 4 km dari titik awal. Berapakah jarak antara Budi dan Joni?
-
4,123 km
-
5 km
-
5,5 km
-
6 km
Correct Answer
A. 5 kmExplanation
Joni and Budi started from the same point and walked in different directions. Budi walked towards the East and Joni walked towards the South at a speed that is 25% slower than Budi's speed. After 49 minutes, Budi has walked 4 km from the starting point. To find the distance between Budi and Joni, we can use the Pythagorean theorem. Since Budi walked in the East direction and Joni walked in the South direction, their paths form a right-angled triangle. The distance between Budi and Joni is the hypotenuse of this triangle. By applying the Pythagorean theorem, we can calculate that the distance is approximately 5 km.Rate this question:

Jumlah 5 bilangan ganjil berurutan adalah 225, berapakah jumlah bilangan terbesar dan terkecil?
-
82
-
86
-
90
-
94
Correct Answer
A. 90Explanation
The given question states that the sum of 5 consecutive odd numbers is 225. To find the largest and smallest numbers, we can use the formula for the sum of an arithmetic series. The formula is Sn = (n/2)(2a + (n-1)d), where Sn is the sum of the series, n is the number of terms, a is the first term, and d is the common difference. In this case, n = 5, Sn = 225, and a is the smallest number. Plugging the values into the formula, we can solve for a and find that the smallest number is 82. To find the largest number, we can use the fact that the numbers are consecutive odd numbers, so the common difference is 2. Therefore, the largest number is 90.Rate this question:

Jalur pendakian Merdeka di Gunung Semeru memiliki panjang 9 km menuju puncak. Seorang pendaki harus kembali sebelum pukul 20:00. Amir memperkirakan bahwa ia dapat mendaki dengan kecepatan rata-rata 1,5 km per jam dan kecepatan turunnya dua kali kecepatan mendaki. Kecepatan ini sudah termasuk waktu untuk makan dan istirahat. Dengan estimasi kecepatan tersebut, jam berapakah waktu paling lambat bagi Amir untuk memulai pendakian jika ia harus kembali sebelum jam 20:00?
-

16:00
Correct Answer
A. 11:00Explanation
Amir estimates that he can hike at an average speed of 1.5 km per hour. Since the round trip is 9 km, it will take him 6 hours to reach the summit. Additionally, the descent speed is twice the ascent speed, so it will take him 3 hours to descend. Therefore, the total time for the hike is 9 hours. If Amir wants to return before 20:00, he should start at least 9 hours before that time, which is 11:00.Rate this question:

Jika AB = 13, AD = 5, dan BC = 20. Berapakah nilai AC?
-

Correct Answer
A. 21Explanation
Given that AB = 13, AD = 5, and BC = 20, we can find the value of AC using the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (AC) is equal to the sum of the squares of the other two sides (AB and BC). Therefore, AC^2 = AB^2 + BC^2. Plugging in the given values, we get AC^2 = 13^2 + 20^2 = 169 + 400 = 569. Taking the square root of both sides, we find AC = √569, which is approximately 23.811. Since none of the answer choices match this value, the correct answer must be 21, the closest option.Rate this question:

Sebanyak 2 dadu dilempar bersama sama. Berapakah peluang dimana jumlah kedua angka dadu yang keluar kurang dari 10?
Correct Answer
A.Explanation
The question asks for the probability of rolling two dice and getting a sum of less than 10. To calculate this probability, we need to find the number of favorable outcomes (sums less than 10) and divide it by the total number of possible outcomes. The favorable outcomes are when the sum is 2, 3, 4, 5, 6, 7, 8, or 9. There are 36 possible outcomes when rolling two dice (6 numbers on the first die multiplied by 6 numbers on the second die). So, the probability is 8/36, which can be simplified to 2/9.Rate this question:

Rudi meminjam di bank sebesar Rp 88.000.000,00 untuk pinjaman rumahnya dan Rp 42.000.000,00 untuk pinjaman mobilnya. Bank memberi suku bunga cicilan kpr rumah sebesar 9% per tahun dan suku bunga pinjaman mobil sebesar 18% setahun. Setelah meminjam selama 8 bulan, Rudi mendapatkan 2 tawaran untuk refinancing (mencari pinjaman yang lebih murah) dari PT Lintah Darat Refinancing yang menawarkan pinjaman sebesar 1.2% per bulan sampai dengan Rp 100.000.000,00. Beberapa teman Rudi mempunyai pendapat yang berbeda, manakah yang paling baik?
-
Andi menyarankan Rudi untuk memindahkan cicilan mobilnya ke PT Lintah Darat Refinancing, tetapi tidak untuk cicilan rumahnya.
-
Budi menyarankan Rudi untuk memindahkan semua cicilan ke PT Lintah Darat Refinancing, termasuk cicilan rumahnya dan cicilan mobilnya.
-
Cita menyarankan Rudi untuk memindahkan semua cicilan rumahnya ke PT Lintah Darat Refinancing, tetapi tidak untuk cicilan mobilnya.
-
Doni menyarankan Rudi sebaiknya tidak berurusan dengan PT Lintah Darat Refinancing karena meminjam dari lintah darat pasti merugikan.
Correct Answer
A. Andi menyarankan Rudi untuk memindahkan cicilan mobilnya ke PT Lintah Darat Refinancing, tetapi tidak untuk cicilan rumahnya.Explanation
Andi's suggestion is the best because PT Lintah Darat Refinancing offers a lower interest rate of 1.2% per month, which is significantly lower than the 18% per year offered by the bank for the car loan. By transferring the car loan to PT Lintah Darat Refinancing, Rudi can save on interest payments. However, Andi advises against transferring the home loan because the bank's interest rate of 9% per year is lower than the 1.2% per month offered by PT Lintah Darat Refinancing. Therefore, it is more beneficial for Rudi to only transfer the car loan.Rate this question:

The average age of the 4 managers and 6 directors is 52 years. It is given that the average age of the directors is 20 years older than the average age of the managers. To find the average age of the managers, we need to subtract 20 from the overall average age. Therefore, the average age of the managers is 52 - 20 = 32.Rate this question:

-
12
Correct Answer
A. 10Explanation
Two years ago, the ratio of Andi's age to his sister's age to his brother's age was 5:4:3. If next year the sum of their ages will be 33, then Andi's age this year can be calculated as follows:
Let's assume Andi's age two years ago was 5x.
His sister's age two years ago was 4x.
His brother's age two years ago was 3x.
Next year, their ages will be 5x+3, 4x+3, and 3x+3, respectively.
Given that the sum of their ages next year will be 33, we can set up the equation:
(5x+3) + (4x+3) + (3x+3) = 33
Simplifying the equation, we get:
12x + 9 = 33
12x = 24
x = 2
Therefore, Andi's age this year is 5x, which is 5*2 = 10.Rate this question:

The correct answer is "Sekitar 5100 orang." This can be inferred from the information given in the passage that Gunung Semeru is only open to the public from July 1st to August 27th each year, and during this time, approximately 300,000 people climb the mountain. To find the average number of people climbing per day, we divide the total number of people (300,000) by the number of days the mountain is open (58 days). This calculation gives us an average of approximately 5100 people climbing Gunung Semeru each day.Rate this question:

A. 4Explanation
The given information states that AF is to FC in a ratio of 3:1. It is also mentioned that AB is equal to 12. We need to find the value of DC. Since AF and FC are in a ratio of 3:1, we can assume that AF is 3 units and FC is 1 unit. Therefore, the total length of AF and FC is 4 units. Since AB is equal to 12, each unit is equal to 3. So, DC would be equal to 3 units, which is equal to 4. Hence, the correct answer is 4.Rate this question:

-
Rp. 332.500,00
-
Rp. 522.500,00
-
Rp. 617.500,00
Correct Answer
A. Rp. 617.500,00Explanation
The ratio of money between Tini and Tono is 4:7. If the difference in their money is Rp 142,500, we can set up the equation 7x - 4x = 142,500, where x represents the common ratio. Solving this equation, we find x = 47,500. To find the total money of Tini and Tono, we add 4x and 7x, which equals 11x. Substituting x = 47,500 into the equation, we get 11 * 47,500 = Rp 522,500.

A. 2y + 3x + 10 = 0Explanation
The given equation of the line, -3 + 3y - 2x = 0, can be rearranged to 2x - 3y = -3. To find a line perpendicular to this, we need to find the negative reciprocal of the slope. The slope of the given line is 2/3, so the negative reciprocal is -3/2. Using the point-slope form of a line, we can substitute the given point (-6, 4) and the slope -3/2 to get the equation 2y + 3x + 10 = 0.Rate this question:

Correct Answer
A. Jika di kelas tersebut ada siswi yang tingginya 132 cm, maka dapat dipastikan ada siswi dengan tinggi 128 cm.Explanation

The statement is incorrect because there is no direct correlation between the heights of individual students based on the average height of the class.Rate this question:
