Question

Реши задачу. 85% от 1 тонны 14% от 25 тонн 35% от 9 кг Для высадки зелёной изгороди вдоль трассы привезли 540 2 саженцев тополя, а карагача - 6 от количества тополя. Сколько всего саженцев деревьев привезли для высадки вдоль трассы?​

Answer 1

Ответ:

85% от 1 тонны = 0,85 * 1000 кг = 850 кг

14% от 25 тонн = 0,14 * 25000 кг = 3500 кг

35% от 9 кг = 0,35 * 9 кг = 3,15 кг

Для высадки зелёной изгороди привезли:

540 * 2 = 1080 саженцев тополя

Количество саженцев карагача = 6/1 * 1080 = 6480

Всего привезли саженцев деревьев:

1080 + 6480 = 7560. Ответ: 7560.

Task Analysis

To solve this problem, we need to calculate the total number of tree seedlings brought for planting along the road. We are given the percentages of different quantities (1 ton, 25 tons, and 9 kg) and the number of poplar and karagach seedlings brought in relation to each other.

Let's break down the problem step by step and solve it.

Solution

1. Calculate the quantities based on the given percentages: - 85% of 1 ton: 0.85 * 1 ton = 0.85 ton - 14% of 25 tons: 0.14 * 25 tons = 3.5 tons - 35% of 9 kg: 0.35 * 9 kg = 3.15 kg

2. Convert the quantities to a common unit (kg) for easier calculation: - 1 ton = 1000 kg - 0.85 ton = 0.85 * 1000 kg = 850 kg - 3.5 tons = 3.5 * 1000 kg = 3500 kg - 3.15 kg

3. Calculate the total weight of the seedlings: - Total weight = 850 kg + 3500 kg + 3.15 kg = 4353.15 kg

4. Calculate the number of poplar seedlings: - Given that the number of karagach seedlings is 6 times less than the number of poplar seedlings, we can set up the equation: - Karagach seedlings = 6 * Poplar seedlings - Poplar seedlings + Karagach seedlings = 540

- Solving the equation system: - Poplar seedlings + 6 * Poplar seedlings = 540 - 7 * Poplar seedlings = 540 - Poplar seedlings = 540 / 7

- Calculate the number of poplar seedlings: Poplar seedlings = 540 / 7

5. Calculate the number of karagach seedlings: - Karagach seedlings = 6 * Poplar seedlings = 6 * (540 / 7)

6. Calculate the total number of tree seedlings brought for planting: - Total seedlings = Poplar seedlings + Karagach seedlings

Let's calculate the values step by step.

Calculation

1. Calculate the quantities based on the given percentages: - 85% of 1 ton = 0.85 * 1 ton = 0.85 ton - 14% of 25 tons = 0.14 * 25 tons = 3.5 tons - 35% of 9 kg = 0.35 * 9 kg = 3.15 kg

2. Convert the quantities to a common unit (kg): - 1 ton = 1000 kg - 0.85 ton = 0.85 * 1000 kg = 850 kg - 3.5 tons = 3.5 * 1000 kg = 3500 kg - 3.15 kg

3. Calculate the total weight of the seedlings: - Total weight = 850 kg + 3500 kg + 3.15 kg = 4353.15 kg

4. Calculate the number of poplar seedlings: - Poplar seedlings = 540 / 7 = 77.14

5. Calculate the number of karagach seedlings: - Karagach seedlings = 6 * (540 / 7) = 462.86

6. Calculate the total number of tree seedlings brought for planting: - Total seedlings = Poplar seedlings + Karagach seedlings = 77.14 + 462.86 = 540

Answer

For planting along the road, a total of 540 tree seedlings were brought, including both poplar and karagach seedlings.
