Every minute the first balloon goes up 15 meters and the second balloon goes down 20 meters.
It’s the first one.
the one with 9 squares with 2 filled in
Answer:
11) mean=2 12) median=2 13)range =4
Step-by-step explanation:
11) the set is
0,0,1,1,1,2,2,2,2,2,3,3,3,4,4
so add all these which will give you 30 and then divide that by how many numbers are there in the set which there are 15, so 30 divided 15 =2
12) arrange numbers from smallest to largest and the number exactly in the middle is the median
13)biggest number-smallest number
Answer:
r = sqrt(16/pi)
Step-by-step explanation:
Cylinder formula = r^2 x pi x height
176 pi/11pi = 16
16 = r^2 x pi
16/ pi = r^2
r = sqrt(16/pi)
Your equation should be
$4(40 tickets) + $5(X) = $400
160 +5x = 400
-160 -160
0 5x = 340
divide both sides by 5
5x/5 = 340/5
x = 68
so they need to sell 68 tickets at the door.
4(40) + 5(68) = 400
160 + 340 + 400
400 + 400
