When using scientific notation, the number (that is not 10 to the nth power) is always between 1 and 10.
For 772,000.0, I've added the decimal to the correct place. In order to get a number between 1 and 10, we will need to move the decimal 5 places. This leaves us with 7.72 x 10^5.
But, as I see that the answer above is not an option, and the only correct answer would be A, It is the only one between 1 and 10, I feel that there may be a mistake. For A to be correct, the original number would be 7,720,000,000.
Best answer: A

Answer:
The length is APPROXIMATELY equal to 12.4.
Step-by-step explanation:
Use the converse of the Pythagorean Theorem (
+
=
[where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:


169-16=153.
≈ 12

Answer: The initial volume is 593.76mL
Step-by-step explanation:
As you do not say anithing about the pressure, i guess that the pressure remains constant.
If the gas is an ideal gas, we have:
P*V = n*R*T
where P is pressure, n is number of moles and R is a constant.
Now, initially we have:
P*Vi = n*R*315°C
finally we have:
P*825mL = n*R*452°C
Now we can take the quiotient of those two equations and get:
(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)
Now we have:
Vi/852mL = 315/452
Vi = (315/452)*852mL = 593.76mL
So when we expand the gas at constant pressure, we increase the temperature.
Answer:
It would be a obtuse triangle instead
Step-by-step explanation:
By using pythagorean and theorem (a^2 + b^2 = c^2)
So it would be 13^2___2^2 + 12^2
When you square them, you get 169___4 + 144
144 + 4 = 148, which is less than 169
SO it would be 169>148
So no, not a right triangle
