Answer:
30
Step-by-step explanation:
Again there are TWO sides so it would be 50% chance of getting head, or 50% of getting tail. So it would probably be 30
Find the distance (in coordinate plane units) from (-4,10) to (-10,-1).
The change in x will be -6 and the change in y will be -11.
Thus, the distance between the 2 pts is, by the Pythagorean Theorem,
sqrt( [-6]^2 + [-11]^2 ) = sqrt(157).
Convert this to miles:
sqrt(157 units^2) = 12.6 units
1.55 mi
12.6 units * ------------- = 19.4 miles (answer)
1 unit
Circumference Formula: 2pi x r
Radius = 20.5
Plug it in:
2(3.14) x 20.5
6.28 x 20.5 = 128.74
Then, convert to pi terms.
128.74 = 41 pi
Therefore the circumference of a circle with a radius of 20.5m is 41pi.
1.84 is 92% of 2.
Not sure if this is what you were going for, but I'm pretty sure you are. Let me know if not!
