Answer:
170,070 residents
Step-by-step explanation:
Original population = 1500 residents
Total population after 6 years is calculated using the formula
A = P(1+r)^t
r is the rate = 120% = 1.2
t is the time = 6 years
P is the original population
A = 1500(1+1.2)^6
A = 1500(2.2)^6
A = 1500(113.379904)
A = 170,069.856
Answer:
Two triangles are similar if they have: all their angles equal; corresponding sides are in the same ratio; But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough. There are three ways to find if two triangles are similar: AA, SAS and SSS: AA

Step-by-step explanation:</h2>
It is given that:
The 60-W lamp is operated continuously for 1 week.
We know that:
1 week=7 days
and 1 day=24 hours
This means that:
1 week=24×7
i.e. 1 week= 168 hours
Also, 1 kW=1000 W
This means that:
1 W=0.001 kW
Hence,
60-W=0. 060 KW
i.e. Power= 0.60 KW
Hence, the energy consumed is:
Energy=Power×Time
i.e.
Energy=0.060×168
i.e.
Energy=10.08 KWh
Also, cost of 1 KWh=18 cents
We know that:
1 cent=0.01 dollar
This means that:
18 cents=0.18 dollar
i.e.
Cost of 1 KWh=$ 0.18
Hence, cost of 10.08 KWh is: $ (0.18×10.08)
i.e.
Cost of 10.08 KWh is: $ 1.8144
