Answer:
The heat death of the universe which is also known as the big chill or big freeze is a conjecture in the ultimate fate of the universe which suggests that the universe would evolve to a state of no thermodynamic free energy and therefore would be unable to sustain processes that increase entropy
Answer:
Hi there!
The correct answer to this question is: 200.96 ft²
Step-by-step explanation:
The equation for the area of circle is A = πr² you know the radius so just plug in the values and you get A = (3.14)(8)² and you get 200.96
The statement is correct about the radionuclide the atomic number is 31, the mass number is 67, and its symbol is superscript 67 subscript 31 baseline upper g a.
To answert the question, we need to know what an atom is.
<h3>What is an atom?</h3>
An atom is the smallest indivisible part of a substance. It is represented by letters.
- It has an atomic number which is the number of protons or electrons present in an atom and is written as a subscript in from of the letter symbol.
- It has a mass number which is the number of protons plus neutrons in an atom and is written as a subscript in from of the letter symbol.
So, since the atom of this radionuclide contains 31 protons and 36 neutrons.
So, its atomic number is 31. Its mass number is number of protons + number of neutrons = 31 + 36 = 67. Its symbol is superscript 67 and subscript 31.
So, the statement is correct about the radionuclide the atomic number is 31, the mass number is 67, and its symbol is superscript 67 subscript 31 baseline upper g a.

ΔADB is a right triangle at ∠D
So, AB ⇒ Hypotenuse & AD,DB ⇒ Legs
∴ 
ΔADC is a right triangle at ∠D
So, AC ⇒ Hypotenuse & AD,DC ⇒ Legs
∴ BC= BD+ DC = 16 + 9 = 25
∴ The perimeter of triangle ABC = AB + BC + CA = 20 + 25 + 15 = 60.
<u>So, The correct answer is option C. 60</u>
