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.

To find the square root of 74.088, we need to determine the number that, when multiplied by itself, equals 74.088. By using a calculator or a mathematical method, it can be determined that the square root of 74.088 is approximately 8.607. Since none of the given options match this value, it appears that the question is incomplete or not readable. An explanation cannot be generated.

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.

The volume of a rectangular prism can be calculated by multiplying its length, width, and height. In this case, the length is 28 cm, the width is 14 cm, and the height is 12 cm. By multiplying these three values together, we get a volume of 4,704 cm³.

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.

The given answer is incorrect because 21² is not equal to 431. The correct answer should be 21² = 441.

The correct answer is "

The volume of a cube can be calculated by multiplying the length of one side by itself twice. In this case, the length of one side is given as 55 cm. Therefore, the volume of the cube is 55 cm * 55 cm * 55 cm = 166,375 cm³.

The correct answer is 5 dan 7. The greatest common divisor (GCD) or the highest common factor (HCF) of 70 and 105 is 35. However, none of the given options include 35. The closest options are 2, 5, and 7. Since 5 and 7 are both prime numbers and are factors of 35, they can be considered as the factors of the GCD.

The decimal form of 3/8 is 0.375.

The given expression can be simplified as the square root of 900 divided by the square root of 25. The square root of 900 is 30, and the square root of 25 is 5. Therefore, the result of the operation is 30 divided by 5, which equals 6.

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.

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.

The correct answer is 20.000 because to convert cubic meters to cubic decimeters, we need to multiply by 1000. Therefore, 20 cubic meters is equal to 20,000 cubic decimeters.

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.

The given expression can be simplified as (72^3) / (6^3). This can be further simplified as 72 * 72 * 72 divided by 6 * 6 * 6. Both the numerator and denominator can be simplified separately to give 373,248 divided by 216. When this division is performed, the result is 1,728.

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.

The given expression is 5^3 * 6^3. This can be simplified by calculating the cube of each number separately and then multiplying them together. The cube of 5 is 125 (5 * 5 * 5) and the cube of 6 is 216 (6 * 6 * 6). Multiplying these two values together gives us 27,000, which is the correct answer.

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.

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. None of the given answer options match this result, so the correct answer is not available.

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.

If the water flow rate is 3,000 liters per minute, then the volume of water flowing per second can be calculated by dividing the flow rate by 60 (since there are 60 seconds in a minute). Therefore, the volume of water flowing per second would be 3,000/60 = 50 liters.

The correct answer is "setiap 1 cm jarak yang sebenarnya mewakili 500.000 cm atau 5 km pada peta." This means that for every 1 cm distance on the map, it represents 500,000 cm or 5 km in actual distance.

The square root of 1.444 is approximately 1.2. Therefore, when squared, 1.2 becomes 1.44, which is very close to 1.444. The closest whole number to 1.2 is 1. Hence, the closest whole number to the square root of 1.444 is 1, which is not one of the given answer choices. Therefore, the correct answer must be the next closest whole number, which is 2. The only option that is close to 2 is 28.
