Number of adult dogs a kennel has = 8 dogs.
Number of puppies = 14 puppies.
<h3>We need to find the ratio of adult dogs to puppies = Number of adult dogs: Number of puppies.</h3><h3>= 8:14.</h3>
Now, we need to write 8:14 in fraction form 
Greatest common factor of 8 and 14 is 2.
.
<h3>Therefore, ratio of adult dogs to puppies is 4:7.</h3>
Answer:
10 incorrect answers
Step-by-step explanation:
Correct answer = +3
Incorrect answer = - 1
Mark scored = 20
Number of correct answers = 10
Let:
Incorrect answers = y
Hence, we can fashion out the expression for total score :
(Number of correct answers * score per Correct answer + number of incorrect * score per incorrect) = total score
(10 * 3) + (y * - 1) = 20
30 - y = 20
-y = 20 - 30
-y = - 10
y = 10

Answer: 3054 in^3
Step-by-step explanation: The formula for the volume of a sphere is V = 4/3 pi r^3, where r is radius.
Since the diameter is 18in, the radius would be 1/2 or 9in, and plugged in V is
V = 4/3(3.1415)(9)^3
