This is how you set up a percent of error proportion:
Amount of error x(Unknown percent)
Actual value = 100(Percents are out of hundreds)

So if you fill it in, it becomes 4 x
 80 =100
Cross multiply, 400= 80x.
Solve.
x=5 so percent error is 5%

Answer:

d Dilation by a scale factor of 2 followed by reflection about the y-axis

Step-by-step explanation:

In each case, the transformation is ...

(x, y) ⇒ (-2x, 2y)

So, a dilation by a factor of 2 is involved. That is what multiplies the coordinates by 2. Reflection in the y-axis is what negates the x-coordinate.

The transformations are ...

A segment of length 94 cm has been rotated d degrees around a center 0. What is the length of the rotated segment? How do you kn

Gekata [30.6K]

Answer:

Length of rotated segment = 94 cm

Step-by-step explanation:

Rotation is transformation of a figure or a segment about a center which rotates the figure or segment about the center with the angle of rotation.

Rotation is that type of transformation in which the image and pre-image are congruent. This means that rotation has no effect on shape and size of figure or segment and thus, the shape and size of the figure or segment remains same after rotation.

It is given that a segment of length 94 cm is rotated $d$ degrees around a center $O$ .
