Answer:
the axis of symmetry is 3.
Step-by-step explanation:
the axis of symmetry is the line that passes through the vertex.
8.25/3 = $2.75 per ice cream
2.75 * 2 = $5.50
It would cost $5.50 for 2 ice cream
I think it is the fourth one
Answer:
0.58x3=1.74
Step-by-step explanation:
first, you line up the numbers, easiest with the 0.58 on top. then, you multiply 3x8, which is 24. you put the four in the hundredths place, and carry the two. then, you multiply 3x5 and get 15, and add the two, making it 17. you put the seven in the tenths place, and carry the one the ones place. then you will multiply three by zero and get zero. finally, you add the one, and your answer is 1.74.
<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
