Answer:
.037 feet
Step-by-step explanation:
perimeter = the sum of all four sides so
perimeter = (4x-9.5) + (9.5x + 10) + (4x - 9.5) + (9.5x + 10) = 27x = 1
therefore x = 1/27 = .037 feet

Answer:
0.225miles per minute for boat and 0.025 miles per minute for current
Step-by-step explanation:
you just gotta love river current problems
lets use the formula d=rt
we're gonna modify it a bit
when your riding in a canoe with the current your going to go faster than against the current so
with the current: d=(r+c)t
against current:d=(r-c)t
where
d=distance
c=rate of water
r=rate of boat
and
t= time
so
4=16(r+c)
4=16r+16c
simplify to
1=4r+4c
2nd equation:
4=20(r-c)
4=20r-20c
solve by elimination:
(1=4r+4c)5
5=20r+20c
-
4=20r-20c
-------------------
1=40c
c=0.025-speed of water
4=20r-20(0.025)
4=20r-0.5
4.5=20r
4.5/20=r
0.225=rate of boat
hope this helps
