Answer:
The correct option is A) 13 to 3.
Step-by-step explanation:
Consider the provided information.
The pet store had 6 puppies selling for $104 each and 12 kittens selling for $24 each. Today, only 2 puppies and 8 kittens were left.
6-2 = 4 puppies sale
12-8 = 4 kittens sale
The cost of each puppies is $104.
Cost of 4 puppies:
4×$104=$416
The cost of each kittens is $24.
Cost of 4 kittens :
4×$24=$96
The ratio of sales of puppies to kittens is:
Hence, the ration of sales of puppies to kittens is 13/3.
Thus, the correct option is A) 13 to 3.

2 × 5 × sin( π / 12 ) = 10 × sin ( π / 12 ) ;
π/12 = ( 180° ) / 12 = 15°.

But, sin ( π/12 ) </span>
<span>= sin 15° </span>
<span>= sin ( 45° - 30°) </span>
<span>= sin 45°· cos 30° - cos 45°· sin 30° </span>
<span>= (1/√2)·(√3 /2 ) - (1/√2)·(1/2) </span>
<span>= ( √3 - 1 ) / (2√2) = </span>

Finally, ( 2.5 ) × ( 2.4 - 1.4 ) = 2.5 cm ;
