Answer:
21
Step-by-step explanation:
You know the length of JK 12
you also know the length of GF 2.5*12=30
HL is a mid segment because it cuts both legs it intersects in half.
Using the rule saying that the mid segment is half the bases added up we can figure out that HL = (12+30)/2 = 21

<span>dΘ/dt = (1/3)/20 = 1/60 rad/sec </span>
<span>5(1/60 ) = 5/60 cm/sec = 1/12 cm/sec </span>
<span>Angular Speed = dΘ/dt = 1/60 rad/sec </span>
<span>Linear Speed = RdΘ/dt = 1/12 cm/sec </span>
Answer: I'm not sure about the first question, I've never been good at equations. The second one is asking for 15x30 = 450. She will make 450 dollars for 15 hours of work.
Step-by-step explanation:
Well, if you divide 140 by 18 you get the unit rate/price. $7.78 is the rounded total!
a) C = 40 + 30t
b) 280 = 40 + 30t
30t = 240
t = 8
