The distance between the library and the grocery store is 4 centimeters on the map. the actual distance is 12 kilometers. what is the scale of the map?

a. 1 centimeter = 3 kilometers
b. 1 centimeter = mc005-1.jpg kilometer
c.4 centimeters = 1 kilometer
d.12 centimeters = 1 kilometer

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
