The scale on a map is 1 in: 55 miles. What is the distance on the map between two cities that are 99 miles apart?

1.8 inches

Step-by-step explanation:

Create a proportion where x is the distance on the map

=

Cross multiply and solve for x

55x = 99

x = 1.8

So, the distance on the map is 1.8 inches

1.8 inches

Step-by-step explanation:

Scales on a map always represent the direct proportion.

Compare the distances as fractions:

Inches on the map

________________  =  

Miles on the ground

x = 1.8 inches

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
