The population of a city is excpted to increase by 7.5% next year. If p represents the current population, which expression repr
erastovalidia [21]
"excepted?"  I think you meant "expected."

In this problem you need to convert that "7.5%" into a decimal fraction:  0.075.
The increase in population will be 0.075 times p, the current population.  You then add that to p, the current population.

But it's easier and faster to multiply p by 1.075.  Thus, 1.075p is the correct answer.

The ratio of wild hogs to florida panthers in a swamp forest 50:2. Find and interpret the value of the ratio.
Alina [70]

The interpretation of the ratio is that there are 2 panthers for every 50 hogs in the swamp forest.

<h3>What does the ratio mean?</h3>

Here we know that the ratio of wild hogs to Florida panthers in a swamp forest 50:2.

For a ratio between elements A and elements B of the form:

a:b

Where a and b are real numbers.

Means that for each a elements of type A, there are b elements of type B

This means that in the swamp forest there are 50 hogs there are 2 panthers.

  • So, if there are 50 hogs, there are 2 panthers.
  • if there are 100 hoghs, there are 4 panthers.
  • if there are 150 hoghs, there are 6 panthers.

etc..

That is the interpretation of the ratio.

The UK has an area of 243,610km2 and a population of 6.41 x 107. Calculate the population density the United Kingdom. Answer to
hodyreva [135]

Answer: Population density the United Kingdom =2.63\times10^2

A= 2.63

B= 2

Step-by-step explanation:

We know that, to calculate the population density, we will divide the population by the size of the area.

i.e. \text{Population density}=\dfrac{\text{Population size}}{\text{Area}}

Given : Area of UK = 243,610 km²1

Population = 6.41 \times 10^7

Then, the population density the United Kingdom would be :

\text{Population density}=\dfrac{6.41 \times 10^7}{243,610}\\\\=\dfrac{64100000}{243610}=263.125487459\\\\\approx263=2.63\times10^2

On comparing to A\times10^B, we get

A= 2.63

B= 2
