Answer:
k=4
Step-by-step explanation:
-The constant of proportionality is defined as the ratio between two directly proportional variables.
-Given that B=4f
#The constant of proportionality is calculated as:
- the equation can be written in the form y=kx,
where y varies directly with x and k is the constant of variation:

Hence, B varies directly with f with a constant of proportionality k=4
Answer:
12 =x
Step-by-step explanation:
We can use proportions to solve
6 x
---- = -------
10 10+10
Using cross products
6 ( 10+10) = x*10
6*20 = 10x
120 = 10x
Divide by 10
120/10 = x
12 =x
C is the correct answer
it's equal to 0.42
good luck
Answer: $1500
Step-by-step explanation:
<u>Given information</u>
Number of puppies = 6
Cost of each puppy = $250
<u>Given expression deducted from the question</u>
Total cost = number of puppies × cost of each
<u>Substitute values into the expression</u>
Total cost = 6 × 250
<u>Simplify by multiplication</u>
Total cost =
