Another number: d
One number: 2d + 9
d + 2d + 9 - 10 = 11
3d - 1 = 11
3d = 12
d = 4
Another Number: 4
One Number: 17
2×4 + 9 = 8 + 9 = 17
Shrink vertically by a factor of 1/4
Given:
Big figure = 20 ft
Small figure = 7 ft
Take note: In finding the scale factor, we must make sure that the measurements of both figures are the same sides or line.
20 feet / 7 feet = 2.86 scale factor.
This means that the big figure is 2.86 times bigger than the small figure.
If the arrow had been pointed from the small figure to the big figure.
7 feet / 20 feet = 0.35 scale factor.
This means that the small figure is only 0.35 of the big figure.
Both are scale factors but in different perspectives.
Hello to Mr Fowler's science class from brainly!!!
Both rates and ratios are a comparison of two numbers. A rate is a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, and a ratio compares two numbers with the same unit.
