Diketahui skala suatu peta adakah 1 : 250.000. Jika dari kota P ke kota Q pada peta tersebut adalah 12 cm, jarak yang sebenarnya antara kedua kota adalah ....
- A.
25 km
- B.
30 km
- C.
35 km
- D.
40 km
Correct Answer
B. 30 kmExplanation
Based on the given scale of 1:250,000, it means that 1 centimeter on the map represents 250,000 centimeters in reality. Since the distance from city P to city Q on the map is 12 centimeters, the actual distance between the two cities can be calculated by multiplying 12 centimeters by 250,000. This equals 3,000,000 centimeters or 30 kilometers. Therefore, the correct answer is 30 km.Rate this question:

Jarak Solo - Semarang pada peta 10 cm. Jika skalanya 1 : 2.500.000 maka jarak sebenarnya adalah
- A.
150 km
- B.
200 km
- C.
250 km
- D.
300 km
Correct Answer
C. 250 kmExplanation
The given information states that the distance between Solo and Semarang on the map is 10 cm. The scale of the map is 1:2,500,000. To find the actual distance, we need to multiply the map distance by the scale. Therefore, 10 cm x 2,500,000 = 25,000,000 cm. Converting this to kilometers by dividing by 100,000 (since there are 100,000 cm in a kilometer), we get 250 km. Hence, the correct answer is 250 km.Rate this question:

Sebuah mobil berangkat dari kota A ke kota B dengan kecepatan rata-rata 75 km/jam. Jarak kota A ke kota B 180 km. Jika mobil tiba di kota B pukul 10.00, mobil tersebut berangkat dari kota A pukul ....
- A.
06.26
- B.
06.46
- C.
07.36
- D.
08.16
Correct Answer
C. 07.36Explanation
The distance between city A and city B is 180 km, and the average speed of the car is 75 km/h. To find the time it takes for the car to travel from city A to city B, we divide the distance by the speed: 180 km / 75 km/h = 2.4 hours.
Since the car arrives at city B at 10.00, we subtract 2.4 hours from 10.00 to find the departure time from city A: 10.00 - 2.4 = 07.36. Therefore, the car departed from city A at 07.36.Rate this question:

Andi berlari menempuh jarak 7 km dalam waktu 30 menit. Kecepatan rata-rata Andi berlari adalah...km/jam.
- A.
14
- B.
17
- C.
21
- D.
28
Correct Answer
A. 14Explanation
Andi berlari menempuh jarak 7 km dalam waktu 30 menit. Untuk menghitung kecepatan rata-rata, kita perlu mengubah waktu menjadi jam. Karena 1 jam memiliki 60 menit, maka 30 menit dapat diubah menjadi 0.5 jam. Kecepatan rata-rata dapat dihitung dengan membagi jarak yang ditempuh dengan waktu yang ditempuh. Dalam hal ini, kecepatan rata-rata Andi adalah 7 km / 0.5 jam = 14 km/jam.Rate this question:

Correct Answer
C. 15Explanation
The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this question, the volume of the rectangular prism is given as 3,600 cm³, and the length and height are given as 24 cm and 10 cm respectively. To find the width, we can rearrange the formula for volume and divide the volume by the product of the length and height. So, 3,600 cm³ divided by (24 cm × 10 cm) equals 15 cm. Therefore, the width of the rectangular prism is 15 cm.Rate this question:

Correct Answer
D. 16Explanation
The volume of a rectangular prism (balok) can be calculated by multiplying its length, width, and height. In this case, the length is given as 23 cm and the width is given as 14 cm. The volume is given as 5,152 cm³. To find the height, we can rearrange the formula to solve for height: height = volume / (length * width). Plugging in the given values, we get height = 5,152 cm³ / (23 cm * 14 cm) = 16 cm.Rate this question:

K = 1.200 cm dan L = 30.375 cm²
- B.
K = 1.220 cm dan L = 50.250 cm²
- C.
K = 1.230 cm dan L = 60.160 cm²
- D.
K = 1.240 cm dan L = 60.750 cm²
Correct Answer
D. K = 1.240 cm dan L = 60.750 cm²Explanation
The correct answer is K = 1.240 cm and L = 60.750 cm². To find the perimeter (keliling) of the cage, we add up all the sides. The perimeter is equal to 2 times the sum of the length and width, plus 2 times the sum of the length and height, plus 2 times the sum of the width and height. In this case, the perimeter is 2(150+75) + 2(150+85) + 2(75+85) = 1240 cm. To find the surface area (luas permukaan) of the cage, we calculate the area of each face and add them up. The surface area is equal to 2 times the product of the length and width, plus 2 times the product of the length and height, plus 2 times the product of the width and height. In this case, the surface area is 2(150x75) + 2(150x85) + 2(75x85) = 60750 cm².Rate this question:

The volume of the rectangular fish tank is given by the formula V = lwh, where l is the length, w is the width, and h is the height. In this case, the area of the base of the tank is given as 1.2 m², and the volume of water needed to fill it is given as 1080 liters. We can convert the volume of water to cubic meters by dividing by 1000, so 1080 liters is equal to 1.08 cubic meters. Since the area of the base is 1.2 m², we can calculate the height by dividing the volume by the area: h = V/A = 1.08/1.2 = 0.9 meters. Therefore, the depth of the fish tank is 0.9 meters.Rate this question:

Correct Answer
C. 73Explanation
The given expression involves the square root of 729 and the square root of 64 multiplied by 2 cubed. The square root of 729 is 27 because 27 multiplied by itself equals 729. The square root of 64 is 8 because 8 multiplied by itself equals 64. 2 cubed is equal to 8. Therefore, the expression simplifies to 27 + 8 x 8 which is equal to 27 + 64. Adding 27 and 64 gives us 91. However, none of the given answer choices match 91. Therefore, the correct answer is not available.Rate this question:

Correct Answer
D. 43Explanation
The area of a square is calculated by multiplying the length of one side by itself. In this case, the area of the square is given as 1.849 cm². To find the length of one side, we need to calculate the square root of the area. The square root of 1.849 is approximately 1.36. Since the length of one side must be a whole number, the closest whole number to 1.36 is 1. Therefore, the length of one side of the square is 1 cm.
