Density is the measurement of the amount of mass per unit of volume. 
In this case we should calculate the density of prairie dog burrows on a square field. This is a surface charge density.It is defined as the total amount of units q per km^2.
to calculate<span> the </span>density of prairie dog burrows, we should divide the total number of  prairie dog burrows in the field <span>by the size of the field. Thus,
</span><span>
 </span>prairie dog <span>burrows in square kilometers= number of dog burrows/ size of the field

size of the field=0.9*0.9=900*900=180000m^2
1980/180000</span><span> m^2= 0.011 dog burrows in square meter 
11 dogs in square kilometer</span>

What is the unit rate of 1.49 for 10
kap26 [50]

If you mean it costs $1.49 to buy 10 items, then the unit rate is $0.15 or 15 cents

This is because you divide 1.49 over 10 like so: 1.49/10 = 0.149, then round this to the nearest penny to get 0.15

0.15 dollars = 15 cents

so basically whatever this item is, it costs 15 cents per item
