Answer:
Step-by-step explanation:
3c + 5w = 16
6c + 2w = 22
-6c - 10w = -32
6c + 2w = 22
-8w = -10
w = 10/8 = 5/4 = $1.25 per lb
3c + 5(1.25) = 16
3c + 6.25 = 16
3c = 9.75
c = $3.25 per lb

Step-by-step explanation:
5. its all of them so just write A, B, C, D, E, F, G
6. (equilateral) triangle, right triangle, diamond (?), parallelogram
7. C and E; A and B
8. not so sure about this one but i think its regular
9. its not a polygon because polygons have straight sides, and this figure does not.
10. the only polygon is C
pay attention in school, it'll help in the long run. even if it sounds boring, it will come in handy one day!!
hope this helped <33333

Answer:
D sqrt( A ) sqrt(pi) / pi = r
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
To find r
Divide each side of the equation by pi
A / pi = pi r^2 /pi
A / pi = r^2
Take the square root of each side
sqrt(A / pi )= sqrt( r^2)
sqrt(A / pi )= r
We do not like leaving square roots in the denominator, so multiply by sqrt(pi)/sqrt(pi))
sqrt(A / pi ) *sqrt(pi)/sqrt(pi))
sqrt( A ) sqrt(pi) / pi = r
× =< 11\2
