Answer:
the factor is this problem is
7(9 - 5)
Step-by-step explanation:
Answer:
9.09
Step-by-step explanation:
x=speed of boat
y=speed of water current
Downstream relative speed = x+y
Upstream relative speed = x-y
Distance remains the same for both upstream and downstream.
a) Distance travelled downstream = speed x time = 3(x+y)
Distance travelled upstream = speed x time = 3.6(x-y)
b) Since both distances are equal, we can write
3(x+y)= 3.6(x-y)
3x+3y = 3.6x-3.6y
6.6y = 0,6x
x=11y: y=x/11
c) Water current has speed as 1/11 times of that of boat
In percent this equals 100/11 = 9.09%
Answer:
The amount in the first account is $5,700
The amount in the second account is $1,300
Step-by-step explanation:
Let the mount invested in the first account be 
and the one invested in the second account be 
.
Then the total principal is 
---->(1)
The interest in the first account is 
The interest in the first account is 
The total interest for the year is 262.00.
This implies that:
---->(2)
We solve the two equations simultaneously to get:
and 
Answer:
4 1/2. Root 18 simplifies to 4.242640687, which is less than 4.50
The choices
A, D, and E, are geometric series
