In mid-2016, the world's population was about 7.4 billion people. The land area of the state of California is about 163,696 square miles.
If in mid-2016, all the world's people were put into California, what would be the population density of California in people per square mile? Round your answer to the nearest thousand
X people per square mile

the population density of California is 45000 people per square mile

Step-by-step explanation:

The formula for determining population density is expressed as

Population density = number of people/land area

In mid-2016, the world's population was about 7.4 billion people. The land area of the state of California is about 163,696 square miles.

If in mid-2016, all the world's people were put into California, the population density of California would be

7.4 × 10^9/163696 = 45205.747

Rounding up to the nearest thousand people per square mile, it becomes

45000 people per square mile

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
