Yang berfungsi untuk membakar campuran bahan dan udara adalah……
- A.
Busi
- B.

Correct Answer
A. BusiExplanation
The correct answer is "Busi". A spark plug, or busi in Indonesian, is a device that ignites the air-fuel mixture in the combustion chamber of an internal combustion engine. It creates a spark that ignites the fuel, allowing it to burn and release energy. Without a functioning spark plug, the engine would not be able to start or run properly. Therefore, the spark plug plays a crucial role in the combustion process by igniting the fuel-air mixture.Rate this question:

- C.
Mencampur air
- D.
Mencampur bensin dan udara
Correct Answer
D. Mencampur bensin dan udaraExplanation
Karburator berfungsi untuk mencampur bensin dan udara. Karburator mengatur aliran bensin ke dalam mesin dengan menggunakan udara sebagai mediumnya. Udara yang masuk ke karburator akan dicampur dengan bensin sehingga terbentuk campuran yang tepat untuk pembakaran di dalam mesin. Campuran bensin dan udara ini kemudian akan dikirim ke ruang bakar untuk proses pembakaran yang efisien. Dengan demikian, karburator memiliki peran penting dalam mengatur campuran bahan bakar yang dibutuhkan oleh mesin kendaraan.Rate this question:

Correct Answer
A. RodaExplanation
The given options are all components of a machine except for "Roda" which means "wheel" in Indonesian. Wheels are not considered a component of a machine as they are separate entities that are attached to machines to enable movement. In contrast, the other options mentioned, such as "Silinder kop" (cylinder head), "seker" (crankshaft), and "Stang seker" (crank handle), are all actual parts of a machine that contribute to its functioning.Rate this question:

- B.
Rantai
- C.
Roda gigi
- D.

Correct Answer
A. Sabuk/beltExplanation
The correct answer is "Sabuk/belt." In automatic motorcycles, the power is transferred from the engine to the wheels through a belt drive system. This belt, also known as a CVT (Continuously Variable Transmission) belt, is made of rubber and is responsible for transmitting the power efficiently. It is a common feature in automatic motorcycles as it provides smoother acceleration and requires less maintenance compared to chain or gear drives.Rate this question:

Correct Answer
A. Menghidupkan mesinExplanation
The starter in a vehicle is responsible for starting the engine. It provides the initial power to the engine, allowing it to ignite and begin running. Without the starter, the engine would not be able to start and the vehicle would not be able to move. Therefore, the correct answer is "Menghidupkan mesin" which translates to "Starting the engine" in English.Rate this question:

Correct Answer
C. KelistrikanExplanation
The correct answer is "Kelistrikan". The explanation for this answer is that the ignition switch (kunci kontak) is a central component of the electrical system in a vehicle. It controls the flow of electricity to various electrical components such as the starter motor, ignition coil, and fuel pump. Without the ignition switch, the electrical system would not function properly, and the vehicle would not start or run. Therefore, the ignition switch is an integral part of the electrical system (kelistrikan) in a vehicle.Rate this question:

Correct Answer
B. Rem cakramExplanation
The correct answer is "Rem cakram" which translates to "Disc brakes" in English. Disc brakes are a type of braking system used in vehicles where a disc rotor is attached to the wheel. When the brakes are applied, brake pads squeeze the rotor, creating friction and slowing down or stopping the vehicle. Disc brakes are known for their efficient stopping power, better heat dissipation, and resistance to brake fade compared to other types of brakes like drum brakes.Rate this question:

- A.
Radiator
- B.
Kompresor
- C.
. Injektor
- D.
Knalpot
Correct Answer
D. KnalpotExplanation
The correct answer is "Knalpot". The exhaust system, which includes the muffler or knalpot, helps to reduce the noise produced by the engine. It is designed to muffle or dampen the sound waves created by the engine's combustion process. Without a properly functioning knalpot, the engine noise would be much louder and more noticeable. Therefore, if the engine noise is not loud, it means that the knalpot is doing its job effectively.Rate this question:

Correct Answer
B. Suspensi/perExplanation
To ensure a comfortable ride on a motorcycle, it is necessary to have a suspension system. The suspension system helps absorb shocks and vibrations from the road, providing a smoother and more comfortable ride for the rider. Without a suspension system, the rider would feel every bump and uneven surface, leading to discomfort and fatigue. Therefore, having a suspension system is essential for a comfortable motorcycle ride.Rate this question:

Sebuah proyek selesai dikerjakan oleh 10 orang selama 18 hari. Agar proyek selesai dalam waktu 12 hari, banyaknya pekerja yang perlu ditambah adalah ... orang.
- A.

- B.
5
- C.
6
- D.
7
Correct Answer
C. 6Explanation
To complete a project in 18 days, 10 people were working on it. To finish the project in 12 days, the number of workers needed to be increased. This can be calculated using the formula: (number of workers) x (number of days) = (constant value). In this case, the constant value is the same for both scenarios. So, (10 workers) x (18 days) = (new number of workers) x (12 days). Solving this equation, we find that the new number of workers needed is 15. Since there were already 10 workers, 5 more workers need to be added to reach a total of 15 workers. Therefore, the correct answer is 6.Rate this question:

- A.
4b+5
- B.
-4b+11
- C.
-4b+5
- D.
4b+11
Correct Answer
A. 4b+5Explanation
The given function is f(x) = 2x - 3. To find the value of f(-2b+4), we substitute -2b+4 for x in the function. So, f(-2b+4) = 2(-2b+4) - 3 = -4b + 8 - 3 = -4b + 5. Therefore, the correct answer is -4b + 5.Rate this question:

{(2,1)}
Correct Answer
B. {(-1,2)}Explanation
The correct answer is {(-1,2)}. This is the solution set for the given system of equations. By solving the equations simultaneously, we can find the values of x and y that satisfy both equations. In this case, when x = -1 and y = 2, both equations are true. Therefore, {(-1,2)} is the solution set.Rate this question:

Diketahui segitiga ABC siku-siku di B dengan panjang AC = 40 cm, dan BC = 24 cm. Titik D terletak pada AB, sedemikian sehingga CD = 25 cm, panjang AD adalah ...
- A.

Correct Answer
D. 26Explanation
Dalam segitiga ABC siku-siku di B, panjang AC adalah 40 cm dan panjang BC adalah 24 cm. Titik D terletak pada AB dan panjang CD adalah 25 cm. Karena segitiga ABC siku-siku, maka panjang AD dapat ditemukan menggunakan teorema Pythagoras. Panjang AD dapat dihitung sebagai akar kuadrat dari panjang AC kuadrat dikurangi panjang CD kuadrat, yaitu √(40^2 - 25^2) = √(1600 - 625) = √(975) = 31.24 cm. Oleh karena itu, jawaban yang benar adalah 26 cm.Rate this question:

- C.
848 cm2
- D.
925 cm2
Correct Answer
A. 748 cm2Explanation
The formula to calculate the surface area of a cylinder is 2πr(r+h), where r is the radius and h is the height. In this case, the diameter of the cylinder is given as 14 cm, so the radius is half of that, which is 7 cm. The height of the cylinder is given as 10 cm. Plugging these values into the formula, we get 2*(22/7)*7*(7+10) = 2*(22/7)*7*17 = 2*22*17 = 748 cm2. Therefore, the correct answer is 748 cm2.Rate this question:

D. 720Explanation
The question is asking for the number of possible ways to choose 3 exemplary students out of 6 candidates. This is a combination problem, where the order of selection doesn't matter. The formula for combinations is nCr = n! / (r! * (n-r)!), where n is the total number of candidates and r is the number of students to be chosen. Plugging in the values, we get 6C3 = 6! / (3! * (6-3)!) = 720. Therefore, there are 720 possible ways to choose the exemplary students.Rate this question:

- A.
986
- B.
924
- C.
704
- D.
462
Correct Answer
B. 924Explanation
The volume of a cone can be calculated using the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone. In this question, the radius is given as 7 cm and the height is given as 9 cm. Plugging these values into the formula, we get V = (1/3)π(7^2)(9) = (1/3)π(49)(9) = (1/3)(3.14)(49)(9) = 3.14(49)(3) = 3.14(147) = 461.58. Rounded to the nearest whole number, the volume of the cone is 462. Therefore, the correct answer is 462.Rate this question:

The given question states that there are ten women with an average height of 165 cm. The question then asks for the average height of thirty people. Since the information only provides data for ten women, it is not possible to accurately calculate the average height of thirty people. Therefore, the question is incomplete and the answer cannot be determined.Rate this question:
