4.4 .
there is 5280 feet per mile. Meaning there is 15840 feet in three miles. Divide 15840 feet by 60(number of minutes in an hour and you get 264 , which is how many feet per minute. Divide 264 by 60(number of seconds in a minute) and you get 4.4, the number of feet per second
Answer:
22.47
22.5 (simplified)
Step-by-step explanation:
22.47 = √(8^2 + 21^2)
12x+7+6x-7=90
12x+6x=90
18x=90
x=5
6(5)-7=
30-7=23
Q=23
Join JH and KH.
You did that so you could measure or calculate the size of <JHK. There are 5 such central angles in a pentagon. If you drew a little circle with H as the center and you went around the circle once, you would have traveled 360 degrees. So <JHK = 360/5 = 72. Make sure you understand that before you read on.
Ok here's the trick. 144 = 2*72. That means that when you rotate the pentagon, you rotate it through Two central angles.
What will happen is that Point J will wind up at Point L and Point K will sit where N is right now. All the points not mentioned will do the same thing. They will move two points clockwise.
