Final answer:
To find the length of the scaled copy of the Mona Lisa in inches, convert the measurements of the actual painting to inches and use the scale factor to find the corresponding length on the notebook cover.
Step-by-step explanation:
To find the length of the scaled copy of the Mona Lisa in inches, we need to convert the measurements of the actual painting to inches and then use the scale factor to find the corresponding length on the notebook cover.
The length of the Mona Lisa is 2 and 1/2 feet, which is equal to 30 inches, and the width is 1 and 3/4 feet, which is equal to 21 inches.
The notebook cover has a length of 11 inches and a width of 9 inches.
The scale factor can be found by dividing the length of the actual painting by the length of the notebook cover: 30/11 = 2.72727 (approximately).
Now, we can find the length of the scaled copy by multiplying the scale factor by the width of the notebook cover: 2.72727 x 9 = 24.54545 (approximately).
Therefore, the length of the scaled copy of the Mona Lisa in inches is approximately 24.55 inches.
