Answer:
if x=3 then y is o
(3,0) is the coordinate points if y is 0
let
r--------> Alvin's average paddling rate in km/hour
y -------> speed of the current
in km/hour
we know that
speed= distance/time
------> solve for distance
distance=speed*time
to Campsite against the current
speed=r-y-----> speed=(r-3)
time=8 hours
distance=(r-3)*8------> equation 2
From Campsite with the current
speed=r+y-----> speed=(r+3)
time=3 hours
distance=(r+3)*3------> equation 1
equate equation 1 and equation 2-----> because is the same distance
(r+3)*3=(r-3)*8----> 3r+9=8r-24----> 8r-3r=24+9-----> 5r=33----> r=6.6 km/hour
therefore
the answer is
Alvin's average paddling rate is 6.6 km/hour
Answer:
0.090
Step-by-step explanation:
In the number 0.496, the number 9 is in the hundredths place.
0.4<u>9</u>6
The value of 9 in 0.496 is 9 hundredths, or 0.090.
Hope this helps.
Each time multiplied by 6/5
the common ratio is 6/5
since |6/5|>1, the series does not converge to a single number and the sum approaches positive infinity
there is no real number that the sum of this series approaches
15 MILES
1 mile = 1.6 km

1.6 24
1.6x = 24
24/1.6 = 15 miles
