When shrinking an image, the size of each side is shrunk by the scale factor. However the area is not shrunk by the same factor. Area is a squared measurement (when finding the area of a rectangle we take length x width; two measurements, so a squared answer), so the area will be shrunk by the scale factor squared; in this case the area is shrunk by 3² or 9. This means the new area would be 720/9 or 80 square inches.
Answer: C. 60
Explanation:
20 percent * 5 = 100 percent
Therefore, 12 plants * 5 = 60 (the total plants in the garden)
Four nickels,
because 1 dime=10¢ and so 21 x .10 = 2.10 and 1 nickel=5¢ so .05 x 4 = .20
2.10 + .20 = 2.30
I’m not sure if the explaining made sense but it’s 4 nickels :)
