The enlargement or a reduction in the dimensions of a building would cause a change in the scale factor is defined below:
<h3 /><h3>What is Scale Factor?</h3>
A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller.
A dilation is a transformation that enlarges or reduces a figure in size. This means that the pre image and image are similar and are either reduced or enlarged using a scale factor.
As seen in the graphics below. A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image.
If the scale factor is between 0 and 1 the image is a reduction.
Using dilation scale factors, we can shrink or expand a figure to the size we desire, knowing that each angle is congruent, each segment is proportional, the slope of each segment is maintained, and the perimeter of the pre image and image have the same scale factor.
Hence, this is how an enlargement or a reduction in the dimensions of a building would cause a change in the scale factor.

Answer:
Step-by-step explanation:
Then Joe and Jeremy will do the job in one hour time
Joe takes 5 hours to do the job then in one hour time he does 1/5
Joe takes 400% as long as the time it takes Jeremy to finish the job
then 5 hours 400
x ?? 100 x = 5/4
So Jeremy will take 5/4 hours to do the job.
Then in one hour working together Joe and Jeremy they will do
1/5 + 1/ (5/4) = 1/5 + 4/5 = 5/5 = 1
Then Joe and Jeremy will do the job in one hour time
And Joe and Joanne will do half job in one hour
A - 12 = -34
a = -34 + 12
a = -22
Answer:
no
Step-by-step explanation:
4 - 3 + 5 = 6 (4-3=1, 1+5=6)
6 + 8 + 4 = 18
Step-by-step explanation:
As we know that
- The circle center is equidistant from all three points, the distance being the circle radius.
- Any point equidistant from two points must lie on the perpendicular bisector of the line segment which join those two points.
- Which is, on the line through the midpoint of the line segment, perpendicular to the line segment.
The perpendicular bisector of the line segment joining the points (1, 1) and (1, 3) will be:
The perpendicular bisector of the line segment joining the points (1, 3), and (9, 2) will be:
These intersect at the center of the circle (5, 2).
The distance between (1, 1) and (5, 2) will be:
So the equation of the circle can be written as:
