Answer:
11
Step-by-step explanation:
The 25 pairs of feet were 7 more than the number of heads, so there were 7 kittens. Hence there were 18-7 = 11 chickens.
Area of trapezoid = 1/2(b1+b2)h
b1 and b2 are top and bottom bases
so b1 = 15.8 and b2 = 21.8
h is height so h = 11.7
so
A = 1/2(15.8 + 21.8)(11.7)
A = 1/2(37.6)(11.7)
A = 219.96
answer
D. 219.96 yd^2
Answer:
m = 11
Step-by-step explanation:
7m - 17 = 60
Add 17 to both sides;
7m = 77
Divide both sides by 7;
m = 11
