Answer:
it is and no solvable statement or no solution problem
Step-by-step explanation:
<h3>Answer:</h3>
Yes, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis
<h3>Explanation:</h3>
The problem statement tells you the transformation is ...
... (x, y) → (x, -y)
Consider the two points (0, 1) and (0, -1). These points are chosen for your consideration because their y-coordinates have opposite signs—just like the points of the transformation above. They are equidistant from the x-axis, one above, and one below. Each is a <em>reflection</em> of the other across the x-axis.
Along with translation and rotation, <em>reflection</em> is a transformation that <em>does not change any distance or angle measures</em>. (That is why these transformations are all called "rigid" transformations: the size and shape of the transformed object do not change.)
An object that has the same length and angle measures before and after transformation <em>is congruent</em> to its transformed self.
So, ... ∆P'Q'R' is a reflection of ∆PQR over the x-axis, and is congruent to ∆PQR.

Answer:
$3.35
Step-by-step explanation:
volume of balloon in the shape of sphere= 4/3 * pi * r^3 = 4.189 cubic foot
cost of 1 cubic foot of helium = 0.8
cost of 1 * 4.189 cubic foot of helium = 0.8 * 4.189 = 3.35
Answer:
109% of increase
Step-by-step explanation:
In order to know the increase in the percentage, we can do this in various methods, however let's follow the method using only rule of 3; you can also do it by the variation index, however, rule of 3 is easier.
First, we need to know the difference between 756$ and 1580$:
1580 - 756 = 824$
Now let's set the rule of three, assuming that 756 is 100% innitial:
756$-------->100%
824$--------> X
Solving for X:
X = 824 * 100 / 756 = 109.9947%
And if you round this number: 109%
