Answer:
The rate at which the population decrease is 59.8 %
Step-by-step explanation:
Given as :
The population of city = 30,31,000
Now The population of city decrease to 22,46,000
The time period in which population decrease is 50 years
Let the percentage rate of decrease = R%
So,
Final population = initial population ×
Or, 22,46,000 = 30,31,000 ×
Or, =
Or, =
=
So , 0.99402 =
Or, = 1 - 0.99402
So, Rate = × 100
Or, Rate = 0.598 = 59.8 %
Hence The rate at which the population decrease is 59.8 % Answer

Answer:
Convectional rainfall. - Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it. This causes the air to expand and rise. As the air rises, it cools and condenses. ... If this process continues, rainfall will occur.
Orographic or relief rainfall. - Orographic or relief rainfall is caused when masses of air are forced up the side of elevated land formations, such as large mountains, often referred to as an upslope effect. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation.
Cyclonic or frontal rainfall. - Frontal or Cyclonic Rain is caused by cyclonic activity and it occurs along the fronts of the cyclone. It is formed when two masses of air of different temperature, humidity and density meets. For example meeting of moisture laden warm tropical wind with a polar air mass. A layer separating them is called the front.

Answer:
Calculate Principal, Interest Rate, Time or Interest. ... You received $72 in interest after 3 years. ... where I is interest, P is total principal, i is rate of interest per year, and t is total time in years. In this example I = $72, i = 4% and t = 3 years, so ...
Step-by-step explanation:
Answer: (6a + 5b) • (6a - 5b)
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "b2" was replaced by "b^2". 1 more similar replacement(s).
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(36 • (a2)) - 52b2
Step 2 :
Equation at the end of step 2 :
(22•32a2) - 52b2
Step 3 :
Trying to factor as a Difference of Squares :
3.1 Factoring: 36a2-25b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 36 is the square of 6
Check : 25 is the square of 5
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (6a + 5b) • (6a - 5b)
Final result :
(6a + 5b) • (6a - 5b)
