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:
3km
Step-by-step explanation:
When you want to find a percent of a number you do this:
given number/ 1 multiplied by percentage/100
so in this question its a multiple step
start with finding 25 percent of 4250 which is= 1062.5
so thats how much the discount is so the amount after the 25% discount is:
4250-1062.5= 3187.5
then you have to add 9% due to fees
so you find 9% of 3187.5 which is= 286.875
so you add 286.875 to 3187.5 gives you= 3437.375 in total cost for the vacation package
