Answer:

76,800

Step-by-step explanation:

Given the following :

Length = 20 kilometers

Width = 12 kilometers

Population density = 320 people per sq km

Population =?

Recall:

Area of rectangle = Length × width

Therefore,

Area of Rectangleville = 20 km × 12 km = 240km^2

Population is related to population density and Area by the formula ;

Population density = population ÷ Area

Therefore,

Population = population density × Area

Population = 320 × 240 = 76,800

Therefore, the population of Rectangleville is 76,800 people

Answer:

First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of Geoff:


The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.


Next, we are going to multiply the ratio between the age of the person and their combined age by £800:

For Eli: 

For Freda: 

For Geoff: 


We can conclude that Eli will get £180, Freda will get £260, and Geoff will get £360.

How much would $500 invested at 3% interest compounded continuously be
77julia77 [94]

Answer:

d

Step-by-step explanation:

598.60

You are given the equation 

A(t) = P*e^(rt) 

Where P = Principal 

r = interest rate 

t = time 

e is a mathematical constant equivalent to approx 2.71828 

You're told the initial Principal is $500, the interest rate is 3%, over 6 years. So you have everything that you need to solve the problem, just plug in the values and solve for A(6) 

A(t) = P*e^(rt) 

A(6) = 500 * e^(0.03 * 6) 

A(6) = 500 * e^(0.18) 

A(6) = 500 * 2.71828^(0.18) 

A(6) = 500 * 1.19721 

A(6) = 598.60861 

So $500 invested 6 years ago at 3% would be worth $598.61 today.
