3. Using the equation: A= 10 • log B, if A = 180, solve for B. PLEASE HELP GIVING BRAINLIEST

B=10^18

Step-by-step explanation:

A=10*log(B)

180=10*log(B)

18=log(B)

10^18=10^log(B)

10^18=B

Therefore, B=10^18

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
