The upstream speed is 4 km/hour and the down stream speed is 6 km/hour
<h3>Calculating Speed </h3>
From the question, we are to calculate the speed of each stream
From the given information,
"<em>Rahul rows 16 km upstream and 24 km down stream taking 4 hours each</em>"
For the Upstream,
Distance = 16 km
Time = 4 hours
Using the formula,
Speed = Distance/ Time
Speed = 16 km / 4 hours
Speed = 4 km/hour
For the Down stream,
Distance = 24 km
Time = 4 hours
Thus,
Speed = 24 km / 4 hours
Speed = 6 km/hour
Hence, the upstream speed is 4 km/hour and the down stream speed is 6 km/hour

Answer:

We can rewrite this expression like this:

And we can use the quadratic formula given by:

Where 
And replacing we got:

And solving we got:

And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Step-by-step explanation:
For this case we know that we have a rectangular playground and the area can be founded with this formula:

Where x represent the width and y the length. From the problem we know that A =1400 m^2 and the heigth is 10m longer than the wide so we can write this condition as:

And replacing this formula into the area we got:

We can rewrite this expression like this:

And we can use the quadratic formula given by:

Where 
And replacing we got:

And solving we got:

And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75

Step-by-step explanation:
Answer:
i think is B.
Step-by-i step explanation:
1119.15×12=13,429.8 deposits per year
cost of principal
PVAO=13,429.8×((1−(1+0.04)^(−15))÷(0.04))=149,317.72
interest
13,429.8×15−149,317.72=52,129.28
down payment
178,000×0.15=26,700
intagible tax
178,000×0.002=356
Total cost
52,129.28+356+149,317.72+26,700
=228,503....answer
