If she earns $10.65 and she worked 38 hours last week, I believe you would just multiply the two to get $404.70.
Answer:
place, space, and scale
Explanation:
A geographer investigate issues from the view point of location according to place, space and the scale.
The place is an element of location that describes the position or the domain of occurrence of issue.
Space refers the area occupied by a body or the area where an issue is domiciled.
The scale refers to the magnitude at which an issue is view or observed.
Geographers tends to synthesize and combine these different lenses to observe and investigate an issue. Almost everything on earth can be correlated spatially using these lenses.
Answer:
The age of the rock = 2800.6 million years = 2.8 billion years.
A simple method of analysis similar to Carbon dating is used to obtain the required age of the rock. Radioactive substances decay according to first order reaction kinetics. So, plugging all the required parameters into the general equation for amount of substance left in a first order decay gives us the age of the rock.
Explanation:
Half life of Uranium-235 = 700 million years (from literature)
The decay of radioactive substances follow first order reaction kinetics.
The general equation is given as
A(t) = A₀ e⁻ᵏᵗ
A(t) = Amount of radioactive substance left after a particular time = 6.25%
A₀ = initial amount of radioactive substance = 100%
t = time that has passed since the beginning = age of the rock = ?
k = decay constant
The decay constant is related to the half life (T) through the relation,
k = (In 2)/T
k = (0.693/700) = 0.00099 /million years
A(t) = A₀ e⁻ᵏᵗ
6.25 = 100 e⁻ᵏᵗ
0.0625 = e⁻ᵏᵗ
In e⁻ᵏᵗ = In 0.0625 = -2.7726
-kt = - 2.7726
t = (2.7726/0.00099) = 2800.6 million years
t = 2.8 billion years.
Hope this Helps!!!
From an economic and strategic perspective, the Strait of Malacca is one of the most important shipping lanes in the world. The strait is the main shipping channel between the Indian Ocean and the Pacific Ocean, linking major Asian economies such as India, China, Japan, Taiwan, and South Korea.
Singapore controls the smallest area of the strait, but the city-state enjoys the biggest economic benefit from shipping activities.
