Answer:
The lions consume 42 pounds of meat each day.
ANSWER
I) 5:11
ii) 5:11
iii) 125:1331
EXPLANATION
Let the side lengths be in the ratio:
x:y
This implies that the area will be in the ratio:
Take positive square root.
Hence the sides are in the ratio:
x:y=5:11
The perimeter of the smaller hexagon is 6×5=30
The perimeter of the larger hexagon is 6×11=66
The ratio of the perimeter is
30:66=5:11
The volume will be in the ratio
5³:11³
125:1331
Answer: B , c, E
Step-by-step explanation:
Given that ,
∡J=90° , ∡k=30° , ∡L=60°
In the triangle ΔJKL,
tan ∠L = tan 60°
⇒ JK÷JL= √3
⇒JK = √3JL
Thus, A is incorrect and B is correct
Again,
cos ∠L = cos60° =0.5
⇒JL/KL = 1÷2
⇒ JL = (1÷2)KL
⇒JL×2= KL
⇒ KL=2JL
Hence, F & D are incorrect and C is correct
Earlier we got,
JK = √3.JL
⇒JL=JK÷√3
and JL= (1÷2).KL
So, JK÷√3=(1÷2)KL
⇒JK÷√3×2 = KL
⇒2.JK= √3KL
⇒JK = (√3÷2).KL
hence E is correct
