If b is inversely proportional to c, and b is 5 when c is 12, find b when c = 20.
a. b = 60
b. b = 4
c. b = 15
d. b = 3

b=3

Step-by-step explanation:

If b is inversely proportional to c then

b is 5 when c is 12, means...

From where we obtain the value of k, the constant needed, which is equals to 5*12=60

Now... to find b when c=20, is just a matter of using our known variables.

i think it is x = 1.2

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
