The set is empty since there are no common elements
<h3>Set theory</h3>
Given the following sets
A={0,2,4,6,8} and B={-2,-4}
Required sets
A n B
Since intersection means that we are to write out all the values common to the set A and B, hence the equivalent set will be;
A n B = {}
The set is empty since there are no common elements

Answer: 81 cookies per tray
Step-by-step explanation:
567/7= 81
Answer:61.8°
Step-by-step explanation:
Length of arc=(theta)/360 x 2 x π x radius
9.7=(theta)/360 x 2 x 3.14 x 9
9.7=56.52(theta)/360
cross multiply
9.7 x 360=56.52(theta)
3492=56.52(theta)
Divide both sides by 56.52
3492/56.52=56.52(theta)/56.52
61.8=theta
theta=61.8°
