Answer:1250 units
Step-by-step explanation:
circumference=7850
Radius=?
Radius=circumference ➗ (2xπ)
Radius=7850 ➗ (2 x 3.14)
Radius=7850 ➗ (6.28)
Radius=1250 units
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>
C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.
Hope that helps.
Answer:
30 is answer bro
Step-by-step explanation:
hope it wI'll help u
Ratio of dog bark is 4:5
Multiply that by 20 each side
Ratio is now 80:100
So 80%
If they walk past 45 time you just have to multiply the ratio 4:5 by 9
36:45
So the dog would bark 36 times
