(1) The correct answer is: Pressure = P = 70 N/m²
Explanation:
Pressure is force per unit area. Mathematically, we can write Pressure as follows:

<span> --- (1)
Where P = Pressure = ?
F = Force = 140N
A = Area = 2.0m²
Plug in the values in (1):
P = 140/2.0
P = 70 N/m²
(2) The air particles in the inflated balloon are in chaotic motion. They are moving randomly and colliding with each other and with the inner wall of the balloon, exerting pressure on the wall of the balloon. Furthermore, they are far apart from each other, which is why when you squeeze the balloon, its shape changes accordingly as long as you are putting pressure on it while squeezing. </span>
Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.
Hope this helped!
The '40 years' is not part of the question. It's just there to prove that
'2% each year' has been the experience for the past 40 years, so it's
a good number to use for the rate of growth, past or future.
So, at any number of years 'Q' after the beginning of "this period",
the population was or will be
Pop = (220,000) (1.02)^Q power.
(This equation is familiar from all of the bank-interest problems
the student has done in past math classes.)
In 10 years after the beginning of "this period",
Pop = (220,000) (1.02)¹⁰ = <em>243,800 </em>(or any reasonably close number)
