a farm has an old pod supported by 650 posts that are placed at 1.2 m intervals how many posts needed to be placed for the nine rows in which the posts will be placed at 1.3 m intervals
To find the number of posts needed for the nine rows, we need to calculate the total number of posts placed in a single row and then multiply it by nine.
In a single row, the posts are placed at 1.2 m intervals. So, the distance covered by a single post and the gap between two posts is 1.2 m.
Therefore, the number of posts needed in a single row can be calculated by dividing the length of the row by the distance covered by a single post and the gap between two posts:
Number of posts in a single row = length of the row / (1.2 m + 1.2 m)
Now, the posts in the new nine rows are placed at 1.3 m intervals. So, the distance covered by a single post and the gap between two posts is 1.3 m.
Therefore, the number of posts needed in a single row for the new interval can be calculated by dividing the length of the row by the distance covered by a single post and the gap between two posts:
Number of posts in a single row for the new interval = length of the row / (1.3 m + 1.3 m)
Finally, to find the total number of posts needed for the nine rows, we multiply the number of posts needed in a single row for the new interval by nine:
Total number of posts needed for the nine rows = Number of posts in a single row for the new interval * 9
Note: Since the length of the row is not provided, it is not possible to calculate the exact number of posts needed.
To determine the number of posts needed for the nine rows, we need to calculate the total number of posts required for one row and then multiply it by nine.
First, let's find the number of posts needed for one row. The old pod is supported by 650 posts placed at 1.2 m intervals.
To calculate the number of intervals, divide the length of the pod by the interval distance:
Number of intervals = Length of pod / Interval distance
Number of intervals = 650 posts / 1.2 m
Next, we need to find the total length covered by the intervals. Multiply the number of intervals by the interval distance:
Total length covered = Number of intervals x Interval distance
Total length covered = (650 posts / 1.2 m) x 1.2 m
Now we know the total length covered by the intervals. We can calculate the number of posts needed for one row using the new interval distance.
The new interval distance is 1.3 m.
To find the number of posts needed for one row, divide the total length covered by the new interval distance:
Number of posts needed for one row = Total length covered / Interval distance
Number of posts needed for one row = [(650 posts / 1.2 m) x 1.2 m] / 1.3 m
Lastly, to find the total number of posts needed for the nine rows, multiply the number of posts needed for one row by nine:
Total number of posts needed = Number of posts needed for one row x 9
Total number of posts needed = [(650 posts / 1.2 m) x 1.2 m] / 1.3 m x 9
Calculate this expression to find the total number of posts required for the nine rows.
