We have to calculate the volume of the pond first
a = 25cm
b = 10cm
c = 15cm
a × b × c =
25cm × 10cm × 15cm =
![{3750cm}^{3}](https://tex.z-dn.net/?f=%20%7B3750cm%7D%5E%7B3%7D%20)
3/5 of the pond is filled up, which means we still need to fill up 2/5 of the pond.
One fifth of the pond:
3750 ÷ 5 = 750
Two fifths of the pond:
750 × 2 = 1500
![1500 {cm}^{3}](https://tex.z-dn.net/?f=1500%20%7Bcm%7D%5E%7B3%7D)
^This is the final answer
Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get
![y](https://tex.z-dn.net/?f=y)
on its own.
<em>Original Equation : </em>
![\frac{y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%7D%7B2%7D%20)
<
<em>New Equation {Changed by Multiplying 2 on Both Sides} :</em>
![\frac{2y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2y%7D%7B2%7D%20)
<
![2](https://tex.z-dn.net/?f=2%20)
(
![-3](https://tex.z-dn.net/?f=-3)
)
And we simplify the equation to get our answer.
<em>Old Equation :</em>
![\frac{2y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2y%7D%7B2%7D%20)
<
![2](https://tex.z-dn.net/?f=2)
(
![-3](https://tex.z-dn.net/?f=-3)
)
<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation
![\frac{y}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%7D%7B2%7D%20)
< -3 simplified is</em>
y < -6.
Hope this helps!

Answer:
A'(-3,3)
Step-by-step explanation:
Point A of the triangle is 2 units below the line. Therefore when refelected over the line, point A will be 2 units above the line. 2 units above the line, y=1, is 3.
Since the triangle is being reflected over y=1, the x coordinate will stay the same, but the y coordinate will change. (If the line was being reflected over x=1, then the y coordinate would stay and the x coordinate would change).
Therefore the new y coordinate will be 3, and the x coordinate will be the same as it was before, -3.
A'(-3,3)
