jake is using a copy machine to increase the size oa a 2-inch by 3-inch picture of a spider. The enlarged picture needs to measure 3 inches by 4.5 inches. What enlargement setting on the copy machine should he use?
3/2 = 1.5
4.5/3 = ?
To determine the enlargement setting on the copy machine, we need to compare the dimensions of the original picture with the desired dimensions of the enlarged picture.
Let's first find the scaling factor that needs to be applied to the original picture.
Original Picture Dimensions: 2 inches (width) by 3 inches (height)
Enlarged Picture Dimensions: 3 inches (width) by 4.5 inches (height)
To find the scaling factor for width:
Scaling Factor (Width) = Enlarged Picture Width / Original Picture Width
Scaling Factor (Width) = 3 inches / 2 inches
Scaling Factor (Width) = 1.5
To find the scaling factor for height:
Scaling Factor (Height) = Enlarged Picture Height / Original Picture Height
Scaling Factor (Height) = 4.5 inches / 3 inches
Scaling Factor (Height) = 1.5
Since both scaling factors are the same (1.5), we can conclude that Jake needs to use an enlargement setting of 1.5 on the copy machine.
