Which scale drawing is a dilation that decreases the size of the original object it represents? Figure 1 is the star with a scale of 1:5, Figure 2 is the octagon with a scale of 2:0.5, Figure 3 is the triangle with a scale of 10:1, and Figure 4 is the pentagon with a scale of 1:0.1.
The scale drawing that represents a dilation that decreases the size of the original object is Figure 4, the pentagon with a scale of 1:0.1.
what is the answer
I apologize for the confusion in my previous response. The correct answer is Figure 3, the triangle with a scale of 10:1. This scale drawing represents a dilation that decreases the size of the original object.
If you want to dilate a square with a side of 6 units to create a square with a side of 18 units, what scale factor should you use?(1 point)
To dilate a square with a side of 6 units to create a square with a side of 18 units, the scale factor can be determined by dividing the length of the side of the larger square by the length of the side of the smaller square.
In this case, the length of the side of the larger square is 18 units and the length of the side of the smaller square is 6 units.
Therefore, the scale factor can be calculated as:
Scale factor = length of larger square / length of smaller square
Scale factor = 18 / 6
Scale factor = 3
So, the scale factor needed to dilate the square would be 3:1.
