Answer:
time period is 260.57 years
Step-by-step explanation:
given data
growth rate = 3.4 % = 0.034
population = 4118000
area P = 29000000000 square yard
to find out
time period that one person for every square yard of land need
solution
we will apply here population growth formula that is
total population P = initial population × 
..............1
here r is rate of growth and t is time period and
we consider here initial population is current population
so put value in equation 1 to get t
29000000000 = 4118000 × 
take ln both side
ln 7042.25 = ln
8.8596 = 0.034 t
t = 260.57
so time period is 260.57 years
Answer:
The total cost is D) $141
Step-by-step explanation:
To solve we can use the equation: 
d= number of days m= number of miles
We know both of these values so we can plug them in and solve.
y= 25(3) + 0.10(660)
y= 75 + 66
y = 141
Answer:
5.5m^2
the area of just the trench is 5.5 m^2
Step-by-step explanation:
The Area of trench only is the total area(trench and garden) minus the Area of garden
Area of trench only = total area(trench and garden) - Area of garden
Area = length × breadth
Substituting the given dimensions;
Total area = 3.5 × 3 = 10.5 m^2
Area of garden = 2.5×2 = 5 m^2
Area of trench only = 10.5 m^2 - 5 m^2
Area of trench only = 5.5m^2
the area of just the trench is 5.5 m^2
Step-by-step explanation:
8x = 1
x = 1/8
So x = 1/8 is the correct answer
