Rp525.000,00 dan Rp225.000,00

Rp225.000,00 dan Rp525.000,00

The given information states that the ratio of the amount of money Revan and Ruly have is 3:7. Since the total amount of money they have is Rp750.000,00, we can divide it into 10 parts (3 parts for Revan and 7 parts for Ruly). Each part is equal to Rp75.000,00. Therefore, Revan has 3 parts, which is Rp225.000,00 and Ruly has 7 parts, which is Rp525.000,00.

To find the area of a square, we multiply the length of one side by itself. In this case, the length of one side of the square is 80 cm. So, the area of the square is 80 cm x 80 cm = 6400 cm². However, the options given are in square meters (m²), so we need to convert the area from cm² to m². Since 1 m = 100 cm, 1 m² = 100 cm x 100 cm = 10,000 cm². Therefore, the area of the square in square meters is 6400 cm² / 10,000 cm²/m² = 0.64 m².

The scale of the map is given as 1:1,200,000, which means that 1 unit on the map represents 1,200,000 units in real life. The distance between city A and B on the map is given as 2.5 cm. To find the actual distance, we need to multiply the map distance by the scale factor. Therefore, 2.5 cm x 1,200,000 = 3,000,000 cm, which is equal to 30 km.

The volume of a cube can be calculated by multiplying the length of one side by itself three times. In this case, the length of one side of the cube is 60 cm. So, the volume of the cube is 60 cm x 60 cm x 60 cm = 216,000 cm³. Since only one-fourth of the cube is filled with water, we need to find out how much water is needed to fill the remaining three-fourths of the cube. Three-fourths of 216,000 cm³ is equal to 162,000 cm³. To convert this volume to liters, we divide by 1000, so the answer is 162 liters.

The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length and width of the rectangle are given as 17 cm and 10 cm respectively. To find the perimeter, we add twice the length and twice the width, which gives us 2(17 cm) + 2(10 cm) = 34 cm + 20 cm = 54 cm. Therefore, the correct answer is 54 cm.

Rp27.000.000,00

Pak Mukmin memiliki tanah seluas 98 hektar dan akan membangun bagian rumah dan sisanya taman. Harga rumput per hektar adalah Rp750.000,00. Kita perlu menghitung biaya untuk menanam rumput di taman tersebut. Jumlah rumput yang diperlukan adalah 98 hektar dikali dengan harga per hektar, yaitu 98 x Rp750.000,00 = Rp73.500.000,00. Namun, kita hanya perlu menghitung biaya untuk taman saja, jadi biaya yang dikeluarkan adalah 98 hektar dikali dengan harga per hektar, yaitu 98 x Rp750.000,00 = Rp73.500.000,00. Oleh karena itu, jawaban yang benar adalah Rp21.000.000,00.

To find out how much Kak Muria needs to pay for 8 pencils, we can set up a proportion based on the information given. Since Zully bought a dozen pencils (12 pencils) for Rp38.400,00, we can set up the proportion: 12 pencils / Rp38.400,00 = 8 pencils / x. Solving for x, we find that x = (8 pencils * Rp38.400,00) / 12 pencils = Rp25.600,00. Therefore, Kak Muria needs to pay Rp25.600,00 for 8 pencils.
