D. 14 times
Step-by-step explanation:
The population of New York City is about 8.18 × 10^6. This is an estimation. The population of Las Vegas is about 5.84 × 10^5. This is also an estimation. We want to determine the number of times that population of new York is more than that of las Vegas. It's like saying how many las Vegas are the in New york.
This is done by dividing the population of new York by the population of las Vegas. It becomes
8.18 × 10^6 / 5.84 × 10^5
= 14.00684931507

Answer:
B
Step-by-step explanation:
The population after 3 years would be 8.20 millions.
Step-by-step explanation:
Given,
Initial population = I = 4.2 million
Growing rate = r = 25%
If the initial population and growing rate is given, the formula to calculate the population (x) after n years would be:
By putting the values in the equation, we get
The population after 1st year (x1) would be
x1 = 5.25 million
Similarly,
x2 = 6.56 million
x3 = 8.20 million
Hence, the population after 3 years would be 8.20 millions.
But, if you are asking about the total population at that time. It would be
I + x1 + x2 + x3 = 24.21 million
The theorem should be same side interior
For this problem, we'll use two proportions:
THE FIRST PROPORTION:
x/86 = 52/100
100x = 4472
x = 44.72
THE SECOND PROPORTION:
x/52 = 35/100
100x = 1820
x = 18.2
FINAL ADDITION:
18.2 + 44.72 = 62.92
The answer is 62.92
Hope this helps!! :)
