Answer:
Explanation:
200 x 4 = 800 - 200 = 600300 x 4 = 1200 - 800 - (800 - 300) = 100325 x 4 = 1300 - 800 - (800 - 325) = -25320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0
Therefore, they met 480 meters from the house.
Balance the combustion reaction:
a C₂H₂ + b O₂ → c CO₂ + d H₂O
Count the atoms on both sides of the reaction:
• C : 2a = c
• H : 2a = 2d
• O : 2b = 2c + d
Let a = 1; then c = 2 and d = 1, and it follows that
2b = 2•2 + 1 = 5
so that b = 5/2, and the balanced reaction is
1 C₂H₂ + 5/2 O₂ → 2 CO₂ + 1 H₂O
or, with integer coefficients,
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O
C₂H₂ has a molar mass of about 26.038 g/mol, so we have a starting amount of
(64.0 g) (1/26.038 mol/g) ≈ 2.46 mol C₂H₂
According to the reaction, we produce H₂O in a 1-to-1 ratio with the C₂H₂ that is burned up, so we end up with about 2.46 mol H₂O.
The effect that the child in the middle of the pool notices is known as <u>constructive interference. </u>
<h3>What is constructive interference?</h3>
- It refers to the phenomenon where two identical waves come into contact with each other and create a new wave that is twice as amplified as their individual amplitudes.
When the waves from the friends on opposite sides reached each other in the middle, they produced more amplified waves that then raised the child in the middle of the pool higher.

Answer:
x=1/2y+2
y=2x-4
Explanation:
For x-intercept:
4x-2y=8
-> subtract -2y on both sides
4x=2y+8
-> divide 4 on both sides to isolate the x
x=1/2y+2
For y-intercept:
4x-2y=8
-> subtract 4x on both sides
-2y=-4x+8
-> divide -2 on both sides to isolate the y
y=2x-4
Yes, Congenial Contexts to some measures do bring about Mobilization, Resignation, Activation, or Complacency.
<h3>What is the study about?</h3>
The study of If Congenial Contexts Lead to Mobilization, Resignation, Activation, or Complacency reveals that;
A person living in a state that is said to be of a political underrepresentation are known to be very likely to be seen pr engage in public forms of actions.
Also the study shows that they did evaluate subgroup analyses to depict the way that contextual association or relationships along with participation are kind of different based on political orientations, e.g. party identification or political interest.
