Answer:

no grass to for them to graze on

Step-by-step explanation:

Given that Over many years the buffalo population out west gradually disappeared

We are given three statements and we have to find the correct likely reason for the above

change in climate over the years may not be most likely since climate changes gradually over the years, giving the animal time to adapt.

Decrease the number of humans in the west may not be correct as buffalo population has nothing to do with this

But grass is the main food for buffalo and hence no grass would make them starve and this may be the most likely reason.

Circle towns limit form a perfectly circular shape that has a population of 20000 in the population density of 480 people per sq

Alex

Answer:

$D =\frac{P}{\pi X^2}$

And solving for the radius we got:

$X = \sqrt{\frac{P}{\pi D}}$

And replacing the data given we got:

$X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km$

And this value converted to meters is $X = 87.40 m$

Step-by-step explanation:

For this case we know the population size $P = 20000$ and we also know the population density $D = 480 \frac{people}{km^2}$

We can assume that the area is a circle. We also know that the formula for the population density is given by:

$D= \frac{P}{A}$

Where P represent the number of people and A the area. Since we are assuming a circle then the area is given by:

$A = \pi X^2$

With X the radius of the circle

And then the populationd density become:

$D =\frac{P}{\pi X^2}$

And solving for the radius we got:

$X = \sqrt{\frac{P}{\pi D}}$

And replacing the data given we got:

$X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km$

And this value converted to meters is $X = 87.40 m$

Two towns that are 31.5km aprt are 3cm apart on a map what is the scale of the map

mel-nik [20]

3 cm on the map represents 31.5 km in reality.

3cm : 31.5 km

1cm : 31.5/3 km

1cm : 10.5km

So the scale on the map is 1cm represents 10.5 km.

How long should the wooden frame be (use 3.14 for pi)

scoundrel [369]

C=2πr
The C stands for circumference
the π is Pi (3.14)
and r is the radius (length of half a circle)

Since the sides are 10 ft you multiply that by 2 to get the length of both sides which gives you 20 feet.

Then to find the circle, since both are half circles. You can just do the normal circumference equation and you will end up with the same answer.

For example in this problem: this problem gives you the diameter but you need the radius of the circle. C=2(π)(1.5)

C=9.42 < this is the circumference of the circle.

Then you add the sides of the table which are 20 feet.

So the final answer is 29.42 feet.
