3.6²
same as multiplying 3.6 × 3.6
Answer:
x=96
Step-by-step explanation:
3/8x=36
Multiply both sides by 8/3.
x =96
You would use the Pythagorean Theorem (a²+b²=c²)
7²+15²=c²
49+225=c²
274=c²
√274=c
or, 16.55=c
The larger integer has to be at least 16.
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>
