6.299 or 6.3 depending on how it wants you to round
16cm / 2.54 cm per in = 6.3 inches
Answer:
I say answer number 2
Step-by-step explanation:
The equation you have to solve is 1.50 + (0.75 • 6). First, you solve what is in the parenthesis, 0.75 • 6 = 4.50. Now you simply add 1.50 and 4.50 to get $6, the total cost for 7 hours worth of parking.
The angular velocity is the linear speed divided by the radius.
ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
ω = 45 degrees/second
Using sine formula we have
8/sin60 = x/sin30
hence x= 8/√3 = 4.62
