Answer:4699990
Step-by-step explanation:
I think I just guessed
A) y= (-1/2)x+50
(y=(-1/2)4 +50 = -2+50= 48)
Y=( -1/2 )8-50=-4+50 =46
B) -1/2X+50>=40
-1/2X>= -10
X<=20
To start the meeting with 40 students it should be 20 minutes or less before the meeting
Draw the line with the zero in the middle
Draw a closed circle at +20 and from that point draw a line to the left
Answer:
nice work hope to see it once its finished!
Step-by-step explanation:
So, this is kinda similar to the other I helped you with:
<span>So r is the radius of the disk. The area is known and equal to 100Pi; so
100Pi = Pi r2
Now for r: r = 10
Circumference = 2 PI r = 20 Pi
I hope this helped!</span>
