The average number of pins he knocks down per role is about 7 1/3
10 + 9 + 7 = 22
22 divided by 3 = 7 1/3
so his pin total would probably be 44
Using the given formula speed = distance over time:
Speed = 70 miles / 3 hours
Speed = 23.33 miles per hour
Convert miles per hour to meters per hour:
1 mile = 1609 meters:
23.33 miles x 1690 meters = 37,543.33 meters per hour.
Now convert meters per hour to meters per second:
1 hour = 3600 seconds:
37,543.33 / 3600 = 10.4 meters per second.
Answer:
Step-by-step explanation:
The roots are very clear on the graph. I have left them unlabeled so that you can put the two points in.
The points are (-4,0) and (-2,0)
The graph was done on desmos which you can look up. The box in the upper left corner was filled with
y = x^2 + 6x + 8
so the sand pile looks more or less like the one in the image below.
let's check its circumference first. We know that dC/dt = 5π
hmmm when the circumference C = 8π, what's the radius "r"?
now let's take the derivative to the volume equation, and check what dV/dt is
Answer:
x = 25 degree
Step-by-step explanation:
5x + 4 = 8x - 71 (being vertically opposite angle)
5x - 8x = -71 - 4
-3x = -75
x = -75/-3
x = 25
