Answer:

Denmark has the most while the US has the least.

Step-by-step explanation:

Pop Desnisty is P/A, where P is population and A is area.

This means that the US has an area of around 29.11.

Denmark has one of 124.72.

Ghana has one of 77.21

I simply took the population of each country, divided it by the area, and then rounded to the nearest hundredth.

Since the question asks for the greatest and least, You'll notice that Denmark has the most while the US has the least.

Answer:

Greatest: Denmark

Least: U.S.

Step-by-step explanation:

The population density is calculated by dividing the population by the area.

U.S.

Population density = 272,648,000/9,364,520 = 29.1

Denmark

Population density = 5,248,000/42,077 = 124.7

Ghana

Population density = 18,339,000/237,533 = 77.2

Greatest: Denmark

Least: U.S.

Find the value of x so that the function has the given value. f(x) = 6x + 9; f(x) = 21
Olin [163]

Answer:

x = 2

Step-by-step explanation:

We need to find the value of x so that the value of given function becomes 21 .

We have ,

f(x)=21\\\\ f(x)= 6x + 9

Now , for finding x ,

6x +9 = 21 \\\\ 6x = 21 -9 \\\\ 6x = 12 \\\\ x = 2

Capital Value Suppose income from an investment starts (at time 0) at $6000 a year and increases linearly and continuously at a
nikdorinn [45]

The capital value$6507.63

Step-by-step explanation:

When an amount is compounded continuously interest it means the principal is continuously earning interest and the interest keeps earning on the interest earned. The formula to apply is;

A=Pe^{rt}

where P is the starting amount, r is the nominal annual interest rate, t is length of time the interest is applied, and e=2.71828

Given that, A=$6000, e=2.71828, r=0.05 and t=1

A=6000*2.71828^{0.05}

A=6307.63

Interest earned= 6307.63-6000 = $307.63

Where the investment increases linearly and at a constant rate of $200 a per , the linear model will be;

A=6000+200t where t is length of time the interest is applied, and A is the amount after t period of time

In this case t=1

A=6000+200*1

A=6000+200 =6200

Interest earned is= $6200-$6000=$200

Capital value = $6000+$307.63+$200 =$6507.63

Luke’s dad need 165 for a new suitcase. If he saves an equal amount for 3 weeks, how much does save each week?
goldenfox [79]
This is easy the answers 55 you just need to divide

165 ÷ 3 = ?

Step 1: Look at the multiplications of three can you make a group with an answer close to one? if not look at 16 and the multiplications of three is there a number close to 16 or exact?

Step 2: In this case 5 × 3 = 15, so 15 is close to 16.


Step 3: Now you need to subtract 16 and 15, 16 - 15 = 1.


Step 4: Like there's no number that has 1 as a answer, you need to lower the 5.


Step 5: Once you lower the five it makes 15 in the in the multiplications of three is there something close to 15 or exact? Yes there is a number that can make 15, it's 5 × 3 so 15 take away 15 makes zero so your answer will be simple, 55.

So Luke's dad needs to save $55 each week.
