The scale of 1:1,500,000 means that 1 centimeter on the map represents 1,500,000 centimeters in reality. Since the distance between Jakarta and Bandung on the map is 12 centimeters, the actual distance between the two cities would be 12 multiplied by 1,500,000 centimeters, which is equal to 18,000,000 centimeters. To convert this to kilometers, we divide by 100,000 (since there are 100,000 centimeters in a kilometer). Therefore, the actual distance between Jakarta and Bandung is 180 kilometers.

To find the sum of 5 5/12 and 13/18, we need to first convert the mixed number 5 5/12 into an improper fraction. Multiplying the whole number 5 by the denominator 12 and adding the numerator 5, we get 65/12. Now, we can add this fraction to 13/18. To add fractions, we need to find a common denominator, which in this case is 36. We convert both fractions to have a denominator of 36 and add the numerators. The result is 117/36, which simplifies to 3 5/36. Therefore, the correct answer is 6 5/36.

The question states that Pak Abdulloh harvested 615 fish and will put them into 41 bags. Since the average weight per fish is 2 kg, we can calculate the total weight of all the fish by multiplying the number of fish (615) by the average weight per fish (2 kg), which equals 1230 kg. To find the weight per bag, we divide the total weight (1230 kg) by the number of bags (41), resulting in 30 kg per bag. Therefore, the correct answer is 30.

The correct answer is 29,371. This is the result of subtracting 2,429 from 31,8.

The team gets a score of 3 for each win, -1 for each loss, and 0 for each draw. Therefore, the team's total score can be calculated by multiplying the number of wins by 3, subtracting the number of losses, and adding the number of draws multiplied by 0. In this case, the team has 6 wins, 3 losses, and 1 draw. So, the score would be (6 * 3) - 3 + (1 * 0) = 18 - 3 + 0 = 15.

The correct answer is 3,825. To find the total weight of all the ingredients needed, we need to add the weights of each ingredient. The weight of 0.875 kg of eggs, 2 1/5 kg of flour, and 3/4 kg of sugar is equal to 0.875 + 2.2 + 0.75 = 3.825 kg. Therefore, the total weight of all the ingredients needed is 3.825 kg.

The question asks for the total amount of liters in three tanks. To find the answer, we need to convert the given measurements to liters.

First, we convert 4,050 dm3 to liters by multiplying it by 1,000 (since 1 dm3 is equal to 1 liter). This gives us 4,050 liters for Tank I.

Next, we convert 6.25 m3 to liters by multiplying it by 1,000 (since 1 m3 is equal to 1,000 liters). This gives us 6,250 liters for Tank II.

Lastly, we convert 6,750 liters to liters (no conversion needed). This gives us 6,750 liters for Tank III.

To find the total, we add the amounts from each tank: 4,050 + 6,250 + 6,750 = 17,050 liters. Therefore, the correct answer is 17,050.

The maximum number of parcels that can be made is 12. This can be determined by finding the greatest common divisor (GCD) of the quantities of biscuits, chocolates, and candies.

A prisma tegak segitiga is a triangular prism, which has two triangular bases and three rectangular faces. Each triangular base has three sides, and each rectangular face has two sides. Therefore, the total number of sides or edges in a triangular prism is 3 + 3 + 2 + 2 + 2 = 12. Hence, the answer of 9 is incorrect.

To calculate the average of 10 test scores to be 8, Ani needs to have a total score of 80 (8 x 10). Since Ani's average score for the first 9 tests is 7.8, the total score for those 9 tests would be 70. To find the score she needs for the 10th test, we subtract the total score of the first 9 tests from the desired total score: 80 - 70 = 10. Therefore, Ani needs to get a score of 10 on the 10th test to achieve an average of 8. However, since the options provided do not include a score of 10, the closest option would be 9.8.

The correct answer is 20 because v841 is equivalent to 841, and 3^2 is equal to 9. Subtracting 9 from 841 gives us 832. Therefore, the result of v841 - 3^2 is 832, which is equal to 20.

The bus traveled from city A to city B for a total of 4 hours (15.30 - 11.30). During this time, it took a 30-minute break, so the actual travel time was 3.5 hours. The distance between city A and city B is 210 km. To find the average speed, we divide the distance by the time: 210 km / 3.5 hours = 60 km/h.

The diameter of the circular shrimp pond is 10 meters. The distance between the edge of the pond and the water channel is 2 meters. To calculate the length of the water channel, we need to find the circumference of the pond. The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter. Therefore, the circumference of the pond is 3.14 x 10 = 31.4 meters. However, we only need to consider the half circumference because the water channel is only built on one side of the pond. Therefore, the length of the water channel that needs to be built is 31.4 / 2 = 15.7 meters. Since none of the given options match this calculation, the correct answer is not available.

Pak Hadi memiliki sawah seluas 8 ha. Satu hektar sama dengan 100 are, sehingga luas sawah Pak Hadi adalah 800 are. Dari luas tersebut, 1.80 are akan dijual, sehingga sisa luas sawah yang akan dibagikan kepada dua anaknya adalah 800 - 1.80 = 798.20 are. Karena sawah akan dibagikan kepada dua anak, maka masing-masing anak akan mendapatkan setengah dari sisa luas sawah, yaitu 798.20 / 2 = 399.10 are. Dalam satuan hektar, ini sama dengan 3.99 hektar. Jadi, masing-masing anak akan mendapatkan 3.99 hektar sawah.

Based on the given image, the shape appears to be a rectangle. The formula to find the perimeter of a rectangle is P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
