Answer:
last year it was 80k
Step-by-step explanation:
Population increases by 5% every year
Last year it was 80,000
PRESENT POPULATION
Present population = 80,000 + 5% off 80,000
= 80,000 + 5/100 × 80,000
= 80,000 + 5 × 800
= 80,000 + 4,000
= 84,000
AFTER ONE YEAR
After this , the population again increases by 5%
Population = 84,000 + 5% off 84,000
= 84,000 + 5/100 × 84,000
= 84,000 + 5 × 840
= 84,000 + 4,200
= 88,200
ANSWERS
The population of present year is 84,000
After one year , the population becomes 88,200
Hope it helps :-)
Answer:
1. The Present population is 84,000
2. The next years population 88,200 and the year after that would be 92,610
Step-by-step explanation:
If you take the previous year and multiply it by 1.05 you you get the current population. After that you take the current population and multiply it again by 1.05 since the population increases by 5% so continue multiplying by 1.05 to get the later years and so forth

A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 40 million years. How many years ago did two species share a common ancestor if the molecules found in these two species differ by a total of eight mutations? 160 million years 320 million years 100 million years 240 million years.
Answer:
Answer: 320 MIlion years
Step-by-step explanation:
IT is not very hard because all you have to do is since it is only 40 million per one rotation and you have eight of them, then it is 320 because 4 times 8 equals 32.

Solve the system of equations
a+s=560
8a+3s=2905
Answer:
a=245 s=315
Step: Solve a+s=560 for a:
a+s=560
a+s=560(Add -s to both sides)
a=−s+560
Step: Substitute −s+560 for a in 8a+3s=2905:
8a+3s=2905
8(−s+560)+3s=2905
−5s+4480=2905(Simplify both sides of the equation)
−5s+4480=2905(Add -4480 to both sides)
−5s=−1575
−5s=−1575(Divide both sides by -5)
s=315
Step: Substitute 315 for s in a=−s+560:
a=−s+560
a=−315+560
a=245

Answer:
49π cm²
Step-by-step explanation:
Diameter (d) = 14 cm
Radius (r) = d/2 = 14/2 = 7 cm
Area of a circle
= πr²
= π × (7)²
= 49π cm²
Hope it helps ⚜
Information provided with us :
Diameter of the given circle is 14 cm.What we have to calculate :
Area of that circle?Performing Calculations :
Here we would be first calculating the radius of the given circle. As we know that radius of the circle is calculated by the formula,
r = d / 2Putting the values,
=> r = 14 / 2
=> r = 7
Therefore, radius is of 7 cm.
Now, heading up to calculate the area of circle.
Formula,
A = πr²Putting the values in the formula,
=> A = 22/7 (7)²
=> A = (22/7) × 7 × 7
=> A = 22 × 7 × 7 / 7
=> A = 22 × 49 / 7
=> A = 22 × 7
=> A = 154 cm²

A small-business owner will lease a billboard to advertise her business. The table shows the linear relationship between the cost of leasing a billboard from Company N and the number of months the billboard is leased. The cost to lease a billboard from a different company, Company P, for x months can be found using P(x) = 100x. For what number of months will the cost of leasing a billboard be the same for both companies?
Number on months, x. - Cost, N
1 - 580
2 - 660
3 - 740
4 - 820
5 - 900
RoC = + 80
A. 9 months
B. 29 months
C. 10 months
D. 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.
Linear functionA linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.

One year, the population of a city was 201,000. Several years later it was 237,180. Find the percent increase.
Answer:
18%
Step-by-step explanation:
% increase = new population - old population x 100
old population. 1
% increase = 237180 - 201000 x 100
201000. 1
% increase = 36180 x 100
201000
% increase = 3618000
201000
% increase = 18%
Suppose a rescue helicopter is 700 feet above sea level descends 300 feet to search for debris or any other signs of a submarine in trouble. When the captain does not see anything, he ascends 200 feet and stays at that altitude while he tries to get a radio signal from the submarine. A few moments later he speaks to the captain and is informed that the submarine is 122 feet below sea level. How far is the helicopter from the submarine?
Answer:
The helicopter is 722 feet from the submarine.
Step-by-step explanation:
700 - 300 = 400
400 + 200 = 600
600 - 122 = 722
