can anybody tell me how to tell me the difference between < > and the ones with lines under them when I'm not on any number line

< represents the less-than sign

> represents greater than

a ≤ b means that it's less than or equal to b

a ≥ b means greater than or equal to

Step-by-step explanation:

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4

step-by-step explanation:

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
