Answer:
Option A.
Step-by-step explanation:
Distance between Bob and the center of the mountain at the base = 19,427.5 ft.
Angle of elevation to the top of the mountain = 25°11'
We know that
1 degree = 60 minutes
1/60 degree = 1 minute
Let the height of the mountain be h.
In a right angled triangle
Therefore, the height of the mountain to the nearest foot 9135. Option A is correct.
Answer:
60.0 L
Step-by-step explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is gas constant,
and T is absolute temperature.
Since n and R don't change:
P₁V₁ / T₁ = P₂V₂ / T₂
(1.08 atm) (50.0 L) / (25 + 273.15 K) = (0.855 atm) V / (10 + 273.15 K)
V = 60.0 L

The product of two integers have rules to follow. If the signs of the integers are identical, whether both positive integers or both negative integers, the product will have always have a positive sign. When the integers have opposite signs, where one has a positive sign and the other has a negative sign, the product will always have a negative sign.
