Answer:13 revolution
Step-by-step explanation:
Given data
Wheel initial angular velocity
=18 rad/s
Contant angular deaaceleration
=2
Time required to stop wheel completely=t sec
0 =18 +
t=9 sec
Therefore angle turn in 9 sec
=
+
=
+
=81rad
therefore no of turns(n) =
n=12.889
13 revolution
Answer:
i cant see that
Step-by-step explanation:
Answer:
Step-by-step explanation:
commutative property of addition : x + y = y + x
example : 2+3 =5 and 3+2 =5 then 2+3=3+2
associative property of addition
x + y + z = (x + y) + z = x + (y + z)
example: 2+3+4 = (2+3)+4 = 5 + 4 =9
2+3+4 = 2+(3+4) = 2 + 7 = 9
Your answer is: y=5
Here are the steps:
<span>4=2/9(4y-2)
=2/9(4y-2)=4
=9*</span>2/9(4y-2)=4*9
=2(4y-2)=36
=2(4y-2)/2=36/2
=4y-2=18
=4y-2+2=18+2
=4y=20
=4y/4=20/4
=y=5
Answer: 3 gallons of water
Step-by-step explanation:
3 gallons of alcohol +3 gallons of water = 6 gallons total
alcohol = 3/6 = 50%
