The distance between ny and boston is 306 km. how long is it on a map (in cm) drawn at a scale of 1: 1,200,000?

25.5 centimeters on the map.

Step-by-step explanation:

Given the actual distance between New York and Boston is 306 km = 306,000 meters = 30,600,000 centimeters.

The map (in centimeters) is drawn at a scale of 1 : 1,200,000.

It means 1 cm of map is actual distance of 1,200,000 in real.

So we can multiply the scale factor with actual distance to find the length on map.

Mathematically, length on map = scale factor * actual distance.

Length on map = (1 / 1,200,000) * 30,600,000

Length on map = 30,600,000 / 1,200,000 = 306 / 12 = 25.5 cm.

Hence, It is 25.5 cm on the map.

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest
