Honolulu covers an area of 68.4 square miles. there are approximately 348,000 people living in honolulu. anchorage, alaska has an area of 1706 square miles and has a population of approximately 298,000 people. how many more people, per square mile, live in honolulu verses anchorage? round to the nearest person per square mile.

4,913 people more per sq mile.

Step-by-step explanation:

First step is to calculate the population density of both cities, then we'll be able to answer the question.

We're looking for a number of people per sq mile... so we'll divide the population by the area.

Honolulu: 348,000 people on 68.4 sq miles

DensityH = 348,000 / 68.4 =  5,088 persons/sq mile

Anchorage: 298,000 people on 1,706 sq miles

DensityA = 298,000 /1 ,706 = 175 persons/sq mile

Then we do the difference...  5,088 - 175 = 4,913 more people per sq mile.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
