Answer:
The figures informed are in different scales and mirrored in this way it will be necessary to rotate 180 about the origin, dilate by a scale factor of 2/3.
Step-by-step explanation:
What is figure rotation?
Rotation is the "turn" of a shape around a point called the center of rotation. The distance to the center of rotation remains constant and the measure of rotation is called the angle of rotation.
In this case, first the figure must be rotated 180 degrees since the images are mirrored and then change the scale so that a dilation of 2/3 occurs.
Answer:
Step-by-step explanation:
The "ab" inside absolute value has to go out positive, such as |-2|=2
Since both the a and b values are positive, the value of |ab| should be "ab"
For example:
a=2
b=3
|ab| = |2*3| = |6| = 6
the one strip is a whole fraction strip and the others are just part of the whole
Answer: B
<u>Step-by-step explanation:</u>
In order to get the best representative sample, you should choose the widest range of students, which is from a random sample of all students.
(A) Choosing from only the 6th graders, eliminates the choices the other grade-level students would choose.
(C) Choosing only from students who participate in after-school activities, eliminates the choices the other students would choose.
(D) Chhosing only from students not participating in the fundraiser is silly since you want to know what the students participating in the fundraiser would choose.
The only possible option is B - students from all grades, regardless of whether or not they participate in after-school activities.
