Question

За 4 дні зі складу було вивезено 4060 кг вугілля,1 дня було вивезено 2 сьомих(дріб) усього вугілля,2 дня 35 відсоткіа решти,3 дня 1ціла 1сьомих(дріб) раза більше ніж другого.Скільки вивезено 4 дня?помогите пж.

Answer 1

1) 4060 ·   =1160 (кг) — вугілля 1-го дня;
2) 4060 – 1160 = 2900 (кг) - решта;
3) 2900 · 0,35 = 1015 (кг) - 2-го дня;
4) 1015 · 1 = 1160(кг) — 3-го дня;
5) 2900 – (1015 + 1160) = 725 (кг) - 4-го дня.
Відповідь. 725 кг.

Answer 2

To solve this problem, let's break it down step by step.

Given Information:

- In 4 days, a total of 4060 kg of coal was transported from the warehouse. - On the first day, 2/7 of the total coal was transported. - On the second day, 35% of the remaining coal was transported. - On the third day, the amount of coal transported was 1 and 1/7 times more than the amount transported on the second day.

Step 1: Calculate the amount of coal transported on the first day.

To find the amount of coal transported on the first day, we need to calculate 2/7 of the total amount of coal. Let's denote the total amount of coal as T.

Amount of coal transported on the first day = (2/7) * T

Step 2: Calculate the remaining amount of coal after the first day.

To find the remaining amount of coal after the first day, we subtract the amount transported on the first day from the total amount of coal.

Remaining amount of coal after the first day = T - (2/7) * T

Step 3: Calculate the amount of coal transported on the second day.

To find the amount of coal transported on the second day, we need to calculate 35% of the remaining amount of coal.

Amount of coal transported on the second day = (35/100) * (Remaining amount of coal after the first day)

Step 4: Calculate the amount of coal transported on the third day.

To find the amount of coal transported on the third day, we need to calculate 1 and 1/7 times the amount transported on the second day.

Amount of coal transported on the third day = (1 + 1/7) * (Amount of coal transported on the second day)

Step 5: Calculate the remaining amount of coal after the third day.

To find the remaining amount of coal after the third day, we subtract the amount transported on the third day from the remaining amount of coal after the first day.

Remaining amount of coal after the third day = Remaining amount of coal after the first day - (Amount of coal transported on the third day)

Step 6: Calculate the amount of coal transported on the fourth day.

To find the amount of coal transported on the fourth day, we subtract the remaining amount of coal after the third day from the total amount of coal.

Amount of coal transported on the fourth day = T - Remaining amount of coal after the third day

Now, let's calculate the values step by step.

Step 1: Calculate the amount of coal transported on the first day:

Amount of coal transported on the first day = (2/7) * T

Step 2: Calculate the remaining amount of coal after the first day:

Remaining amount of coal after the first day = T - (2/7) * T

Step 3: Calculate the amount of coal transported on the second day:

Amount of coal transported on the second day = (35/100) * (Remaining amount of coal after the first day)

Step 4: Calculate the amount of coal transported on the third day:

Amount of coal transported on the third day = (1 + 1/7) * (Amount of coal transported on the second day)

Step 5: Calculate the remaining amount of coal after the third day:

Remaining amount of coal after the third day = Remaining amount of coal after the first day - (Amount of coal transported on the third day)

Step 6: Calculate the amount of coal transported on the fourth day:

Amount of coal transported on the fourth day = T - Remaining amount of coal after the third day

Now, let's substitute the given values and calculate the result.

Given: - Total amount of coal transported in 4 days = 4060 kg

Let's denote the total amount of coal as T.

4060 = T

Substituting this value into the equations from the previous steps, we can calculate the amount of coal transported on each day.

I'll calculate the values for you.
