Answer:
33 ft
Step-by-step explanation:
The distance of interest is apparently not the straight-line distance from the top of the vertical ladder to the ground (20 ft), but the length of the arc the top of the ladder makes as it rotates. That arc length (s) is given by ...
s = r·θ . . . . . where θ is the angle in radians subtended by the arc
Here, the radius is 20 ft, and the angle is the supplement of 85°, or 95° = (95/180)π radians.
s ≈ (20 ft)·(1.65806 radians) ≈ 33.16 ft ≈ 33 ft

Answer:
$8190
Step-by-step explanation:
So we know that were putting away $2 each month from our allowance.
Jan-$2
Feb-$4
March-$8
April-$16
Ok so we already put away 4 months of our allowance from 12. So we need 8 more months to count how much.
So lets add: 2 + 4 + 8 + 16=30
Now we need to figure out how much in May and so on.
May- 16x2=32
June-32x2=64
July-64x2=128
August-128 x 2=256
September-256 x 2=512
October-512 x 2=1024
November-1024 x 2=2048
December-2048 x 2=4096
In total to add:
2 + 4 + 8 + 16 + 32 +64 + 128 + 256 + 512 + 1024 + 2048 + 4096 = 8190
Hope this helps :)
