Hey there!
Answer:
CD = 3.
Step-by-step explanation:
Since the triangles are similar, we can set up a ratio to determine the other side-lengths:
Cross multiply:
Distribute the '6':
Combine like terms and simplify:
Therefore, the length of CD is 3.
Answer:
1
Step-by-step explanation:
definite integral from 0-2 of root x dx
root x = x^½
integral of x^½ = ⅔x^(3/2)
Answer: 30 degrees
This is the minimum amount of rotation.
Why this value? Well because 360/12 = 30
Consider a triangle with 3 sides. Specifically I mean an equilateral triangle. We can rotate it 120 degrees to have it line up with itself. Now notice that 360/3 = 120.
For a square, we can rotate it 90 degrees and we can say 360/4 = 90
So the general rule is that the minimum angle of rotation is 360/n, where n is the number of sides. This rule only works for regular polygons. Regular polygons have the same side length and the same angle measure (the side and angle measure won't necessarily be equal).
So going back to this 12 sided dodecagon, we have n = 12 and 360/n = 360/12 = 30 as the minimum angle of rotation. Each 30 degree rotation will have the polygon match up perfectly with its old image. The preimage and image will be identical.

i would say Logan’s is the best because he has the most sorry if I’m wrong. And I’m not good at Englis.
Answer:
$15
Step-by-step explanation:
Set up a proportion where x is the clearance price of the $40 shirt:
= 
Cross multiply and solve for x:
32x = 480
x = 15
So, the clearance price is $15
