A printer is printing photos. For every 20 photos, the printer takes 4 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
Number of photos 20 35 50
Time (minutes) 1 4 8
Number of photos 20 35 50
Time (minutes) 1 4 8
what are the missing numbers
The missing numbers in the table can be calculated based on the given information.
From the given information, we know that for every 20 photos, the printer takes 4 minutes.
To find the time it takes to print 35 photos, we can calculate:
35 photos = (35/20) * 4 minutes = 7 * 4 minutes = 28 minutes
To find the time it takes to print 50 photos, we can calculate:
50 photos = (50/20) * 4 minutes = 10 * 4 minutes = 40 minutes
So the completed table is:
Number of photos Time (minutes)
20 1
35 4
50 8
To complete the table, we need to determine the relationship between the number of photos and the time it takes to print them.
From the given information, we know that for every 20 photos, the printer takes 4 minutes. Therefore, the ratio of photos to time can be calculated as:
Ratio = Number of photos / Time (minutes)
To find the time it takes to print a given number of photos, we can use this ratio and cross-multiply:
Time (minutes) = Number of photos / Ratio
From the given data, we can calculate the ratio as:
Ratio = 20 photos / 4 minutes = 5 photos/minute
Now, we can use this ratio to complete the table.
For 35 photos:
Time (minutes) = 35 photos / 5 photos/minute = 7 minutes
For 50 photos:
Time (minutes) = 50 photos / 5 photos/minute = 10 minutes
Completing the table:
Number of photos | Time (minutes)
-----------------+---------------
20 | 1
35 | 7
50 | 10
