Answer:
Hey there!
We can write the proportion:
101640=4840x
x=21
The car would need 21 gallons of gas to travel 1155 miles.
Let me know if this helps :)
6 consecutive even numbers...x, x + 2, x + 4, x + 6, x + 8, x + 10
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 126
6x + 30 = 126
6x = 126 - 30
6x = 96
x = 96/6
x = 16
x + 2 = 16 + 2 = 18
x + 4 = 16 + 4 = 20
x + 6 = 16 + 6 = 22
x + 8 = 16 + 8 = 24
x + 10 = 16 + 10 = 26
ur numbers are : 16,18,20,22,24,26
Answer:
787.5 km
Step-by-step explanation:
The range of the motorcycle is ...
(30 L)/(8 L/(100 km)) = 375 km
but the driver must stop to refuel after 300 km. At the second fuel stop, he will have covered 300 km × 2 = 600 km. On half a tank, he can cover an additional 375/2 km = 187.5 km. His total distance covered will be ...
2 × 300 km + 187.5 km = 787.5 km
_____
A "full refuel" will consist of adding 24 L to the 6 remaining in the tank at each of the fuel stops.
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
