Intersecting chord theorem:
7 * 7 = 10 *x
49 = 10x
x = 49 / 10
x = 4.9 cm
Answer:
238
Step-by-step explanation
(10*10)+(10*7)+(4*10)+(4*7)
Well, a distance-preserving transformation is called a rigid motion, and the name suggests that it <em>moves the points of the plane around in a rigid fashion.</em>
A transformation is distance-preserving if the distance between the images of any two points and the distance between the two original points are equal.
If that's confusing, I get it; basically if you transform something, the points from the transformation are image points. Take the distance from a pair of image points, and take the distance from a pair of original points, and they should be the same for a <em>rigid </em>motion.
I keep emphasizing this b/c not all transformations preserve distance; a dilation can grow or shrink things. But if you didn't go over dilations, don't say nothin XD
Out of 15, 5 of men older than 30 did have facial hair, which means out of 15, 5 people is 1/3 or 33.3% of the 15 men.
Answer:
- 0.625 5/6=0.625
- 0.222 (repeating) 2/9=0.222
- 0.432 (repeating) 16/37=0.432
- -0.111 (repeating) -1/9=-0.1111
- 0.45 27/50=0.45
- -0.75 -3/4=-0.75
22. -2 21/50 .42=42/100=21/50
23. -4/25 .16=16/100=4/25
24. -13/20 .65=65/100=13/20
25. 31/50= 0.62
26. 7/15= 0.466 (repeating)
