Answer:
42 Volunteers
Step-by-step explanation:
The time (T) that it takes a group of volunteers to construct a house varies inversely as the number of volunteers (V).
This is written as:
The answer should be 2+5+n.
They’re complementary angles because they form a 90 degree angle when put together
From the question, we know that the solutions of the system
is (14,6), which means the speed of the the boat in calm water,
, is 14
, and the speed of the current,
, is 6
. To summarize:
and
We also know that w<span>hen the boat travels downstream, the current increases the speed of the boat; therefore to find the speed of the boat traveling downstream, we just need to add the speed of the boat and the speed of the current:
</span>
<span>
Similarly, to find the the speed of the boat traveling upstream, we just need to subtract the speed of the current from the speed of the boat:
</span>
<span>
We can conclude that the correct answer is </span><span>
C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.</span>
5 times 325=5x-y should be the equation.
