there are .001 meters in 1 millimeter
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
Answer:
Perimeter 18.8
area 15
Step-by-step explanation:
Use pythageriums theorem
6^2 + 5^2 = c^2
I found the sides by counting squares
6^2 + 5^2 = 61
square root it to find the answer
7.8 is the missing side so now add it all together
7.8+6+5= 18.8
to find the area do 6 x 5/ 2
so the answer is 15
Answer:
$1,430
Step-by-step explanation:
$2.75 x 10 gallons= $27.50 a week
There are about 52 weeks in a year.
$27.50 x 52 weeks = $1,430 a year
Answer:
15
Step-by-step explanation:
-3x = -5-10
-x=-15
therefore, x=15
