36 seconds.
The first time the two gears will complete their rotations at the same time will be after 18 seconds. One gear will have rotated three times, the other, two. Keep counting the multiples of either number until you reach one that both 9 and 6 have. The next one after 18 is 36.
Answer:
Step-by-step explanation:
The diagonals of a rhombus are perpendicular, so ∠AED = 90° and ∠BEC = 90°.
∠DAE = 180° - ∠AED - ∠EDA = 180° - 90° - 35° = 55°
BD is a transversal across parallel sides AD and BC, so ∠EBC = ∠EDA = 35°.
∠BCE = 180° - ∠BEC - ∠EBC = 180° - 90° - 35° = 55°
Answer: b
Step-by-step explanation: There was the same question on brainly and they said that the submarine sandwich one was right.
Well think, 24= 8x4 right? So, 2 can go into 24 which=12 so lets divide.
24÷2= 12
12÷2=6
6÷2=3
3 is the smallest we can get so can 3 go into 24? yes, so 8 times
so the smallest they can be are 8*3 and you cant reduce 8 anymore because of the three once one gets the smallest they both do. hope this helped.
