Question

Маслобойня переработала поступившие семена подсолнечника за 3 дня.В первый день она переработала 35% всех семен,что составило 49 тонн.В третий день было переработано 6\7 того,что во второй день.Сколько семян подсолнечника было переработано во второй и сколько в третий день? ,

Answer 1

х-всего семян

в 1 день 0.35х=49

х=140

во второй день было переработано 140-49=91 тоннн во 2 и 3 день

x+6x/7=91

7x+6x=637

13x=637

x=49

 2 день 49 тонн

 в 3 день 42 тонны

 

 

Answer 2

Calculation of Seeds Processed on the Second Day

To find out how many sunflower seeds were processed on the second day, we need to calculate the total number of seeds and the percentage processed on the first day.

Let's assume the total number of sunflower seeds is represented by x.

According to the information given, on the first day, 35% of all the seeds were processed, which amounted to 49 tons.

Mathematically, we can represent this as:

0.35x = 49

To find the value of x, we can divide both sides of the equation by 0.35:

x = 49 / 0.35

Using a calculator, we find that x ≈ 140.

Therefore, the total number of sunflower seeds is approximately 140.

Now, to determine the number of seeds processed on the second day, we need to subtract the seeds processed on the first day from the total number of seeds.

Since 35% of the seeds were processed on the first day, the remaining 65% will be processed on the second day.

Mathematically, we can represent this as:

0.65x = seeds processed on the second day

Substituting the value of x we found earlier:

0.65 * 140 = seeds processed on the second day

Using a calculator, we find that seeds processed on the second day ≈ 91.

Therefore, approximately 91 sunflower seeds were processed on the second day.

Calculation of Seeds Processed on the Third Day

According to the information provided, on the third day, 6/7 (or approximately 85.7%) of what was processed on the second day was processed.

To find out how many seeds were processed on the third day, we can multiply the number of seeds processed on the second day by 6/7.

Mathematically, we can represent this as:

(6/7) * seeds processed on the second day = seeds processed on the third day

Substituting the value we found earlier:

(6/7) * 91 ≈ seeds processed on the third day

Using a calculator, we find that seeds processed on the third day ≈ 78.

Therefore, approximately 78 sunflower seeds were processed on the third day.

To summarize: - Approximately 91 sunflower seeds were processed on the second day. - Approximately 78 sunflower seeds were processed on the third day.

Please note that the calculations provided are approximate due to rounding.
