The answer is 8/12 because you find a common denominator which is 12 so if you multiply 4×3 on the bottom you do it to the top which gives you 3 so 11-3 is 8. 11/12 - 3/12
Let r represent the radius of the smaller circle and R the radius of the larger
circle.
Apply ratios: the radius of the smaller circle to the radius of the larger circle.
r: R = 3 : 7.
I complete rotation = 360 degrees.
1st:
For one complete rotation of the smaller circle, the larger circle is rotated through (3/7)*(360) = 154.3 degrees
2nd:For one complete rotation of the larger circle, the larger circle is rotated through (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios: The number of rotations = R/r = 7/3 = 2.3 rotations
Hope this helped☺☺
Answer:
I think it is b
Step-by-step explanation:
it is just rotating the size is not changing
Answer:
the answer is 11
Step-by-step explanation:
Due to the was its set up changes the way it looks. 5+(3+x)=19 and once its simplified 8+x=19 just subtract 8 from 19 and you get 11 so x=11.
