Firstly, the rate of increase of Canton = 80/7720 = 0.010
The rate of increase of HP = 120/3200 = 0.0375
Apply the formula of compound interest==> A =A'(1+i)^n
The population will be equal when the following equality is satisfied
7720(1+0.01)^n = 3200(1+0.0375)^n
or
7720x1.01^n = 3200x1.0375^n
Divide both sides by 3200 ===>(193/80)x1.01^n=1.0375^n
Answer:
6 full episodes
Step-by-step explanation:
You will need to convert 2.5 hours to minutes and divide by 24. Round to the nearest whole number.
50=t/2+8
50-8=t/2
42=t/2
2×42=t
84=t
check: 50=84/2+8
50= 42+8
50=50

Answer:
Required,
Step-by-step explanation:
Given volume and depth respectively,
and 
To find length and width of the rectanglular swiming pool we know,
Volume=length
heightdepth.
Let depth=D=x-3, length=L, width=W, then
After divide we will get 
with remainder -144.
Thus,
Now to find root of,
Thus,
