Answer:
Step-by-step explanation:
6(x²+15)
Answer:
the answer is 22 minutes
Step-by-step explanation:
because when you need to add 2 to get 12:25 and then u add 20 more minutes which then gives takes u to 12:45 then add the time u added and that is the answer, 22 minutes
<u>Question 1 solution:</u>
You have two unknowns here:
Let the Water current speed = W
Let Rita's average speed = R
We are given <em>two </em>situations, where we can form <em>two equations</em>, and therefore solve for the <em>two unknowns, W, R</em>:
Part 1) W→ , R←(against current, upstream)
If Rita is paddling at 2mi/hr against the current, this means that the current is trying to slow her down. If you look at the direction of the water, it is "opposing" Rita, it is "opposite", therefore, our equation must have a negative sign for water<span>:
</span>R–W=2 - equation 1
Part 2) W→ , R<span>→</span>(with current)
Therefore, R+W=3 - equation 2
From equation 1, W=R-2,
Substitute into equation 2.
R+(R–2)=3
2R=5
R=5/2mi/hr
So when W=0 (still), R=5/2mi/hr
Finding the water speed using the same rearranging and substituting process:
1... R=2+W
2... (2+W)+W=3
2W=1
W=1/2mi/hr
Answer:
This is late you said it was due 5 min. yet I this was posted 5 hours. No one can help now.
Step-by-step explanation:
It would be 6.5. The 5 after the decimal would stay the same since the number after it isn't greater than 5
