Answer:
5 chickens, 20 goats
Step-by-step explanation:
We can set up two equations and use substitution
There are 25 total goats and chickens, so

Goats have 4 feet and chickens have two, so

By solving for G in the first equation,

We can now use substitution,

We have 5 chickens, so we have 20 goats.
Let's double check:

It checks out!
For me it’s A not sure tho
A=10 combine like terms which gives you a+2=12 then subtract two from both sides which gives you 10
A= π r2 and v=3.14d
---Volume(v=3.14d):
3.14(15) equals 47.1
47.1 rounds to 47
nearest hundreth would be 0 that rounds to .1 or .10,which rounds to 47
v=47
---Area(π r2)
3.14(7.5)^2 is 3.14(56.25)
176.625
176.625 rounded to the nearest hundreth is 176.630.
Answer:
The area of a circle with the diameter of 15 is 176.630.
Answer with explanation:
→A polygon is a simple closed curve. So , a closed curve occupies area.
⇒When we use the word area, it describes two dimensional closed geometrical object.It is not necessary that ,the shape is polygon only, it should be a simple closed curve.For,example, Circle, Combination of Part of curve and line segments, but it should be a closed curve.
⇒There are some open curves , which occupies area ,but the curve is not closed from both sides, so we can't predict it's area precisely.Therefore , open curves does not come into consideration when we use the word area.
Therefore, Here "Sometimes" word is used.
So, Yes ,Selecting either a polygon or an area will sometimes reveal the area
