Answer:
The wheels make 512 revolutions per minute
Step-by-step explanation:
Diameter of truck = 36 in
Speed = 55 mi/h
Revolutions per minute =?
Radius r = diameter / 2
r = 36/2
r = 18 inches
Speed = 55 mi/h
1 mile = 63360 inches
55 miles = 55*63360 inches
55 miles = 3484800 inches
1 hr = 60 minutes
Speed = 3484800 inches/60 minutes
Speed = 58,080 inches/min
The formula used to calculate the revolutions per minute is:
revolutions = speed/Circumference
revolutions = 58,080 / 2*3.14*18
revolutions = 58,080 /113.4
revolutions = 512.16
revolutions = 512 revolutions per minute
So, The wheels make 512 revolutions per minute
166.19
166
166.158
those are just some of the options
Answer:
-1/5
Step-by-step explanation:
down 1, right 5
it seems the picture is flipped though for some reason
Answer:
b = 80
Step-by-step explanation:
-44 + b = 36
b = 36 - (-44)
b = 36 + 44
b = 80
Hope that helps!
Answer :
The Correct Option is B) Hexagon
Step-by-step explanation :
Let number of sides in a polygon be n
The triangles are created by drawing the diagonals from one vertex to all the others.
Since there is no overlapping of the triangles so no diagonal will be drawn back to itself, and the diagonals to each adjacent vertex would lie on top of the adjacent sides, therefore number of diagonals from a single vertex is three less the the number of sides, or n - 3 and the number of triangles is one more than that, so n - 2.
⇒ Number of triangles = number of sides in polygon - 2
⇒ Number of triangles = n - 2
⇒ n = 4 + 2
⇒ n = 6
And the polygon containing 6 sides is called Hexagon
Hence, the correct Option is B) Hexagon
