Step-by-step explanation:
hope you can understand
The new diameters of the photograph would be 15 inches by 22.5 inches.
If 1 cm = 1.5 in
Then
10 cm = 15 in
15 cm = 22.5 in
The answer is c, right 4 down 3
The greatest common factor is 18
36/90 =2/5
18.2=36 and 18.5=90
So we know that the bacteria grows 3x as much every ten minutes. From this we know that it'll be 3 mm in 20 minute. Continuing the pattern, we can figure out that in 40 minutes the bacteria will be 81 mm.
The pattern: 10min - 3 20min - 9 30min - 27 40min - 81
