<span>It could be C. If the blade spends twice in a minute, it would be 30 seconds. 30=2pi/B=pi/15. </span>
Answer: whats the question?
Step-by-step explanation:
Angles on a straight line add up to 180°, so:
x + 60 = 180
x = 180 - 60
x = 120°
Answer:
The point slope equation is: y - y1 = m (x - x1)
m = slope
Step-by-step explanation:
To use this equation, you need to know:
-<u> </u><u>one point on the line</u>
-<u> the slope of the line</u>
<u>First</u>:
(x1,y1) = a known point on the line
m = the slope
(x,y) = any other point on the line
<u>Now</u>:
we plug the numbers into the equation to get y - y1 = m (x - x1)
<u>Then</u>:
you solve the equation
Probably 2 hours.
You can't drive 100 miles in 55 seconds, or 35 minutes, or 70 minutes (1.16 hrs.)
Hope this helps, good luck! :]
