PLEASE HELP I WILL MARK BRAINLEIST The scale used on a map is 5 millimeters represents 32 kilometers. How many millimeters represent 160 kilometers?

160 mm
25 mm
1 mm
800 mm

25 mm

Step-by-step explanation:

Set up a proportion where x is the number of millimeters for 160 kilometers

=

Cross multiply and solve for x:

32x = 800

x = 25

So, 25 millimeters represent 160 kilometers

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
