Dos engranes giran al mismo tiempo y ambos coinciden en el giro 20.Se sabe que uno gila 4 veces mientras el otro lo hace 5 veces ¿en que giro coincidiran nuevamente?

40

Step-by-step explanation:

According to the statement we have that both begin at the time.

Gear 1 = 4 turns

Gear 2 = 5 turns

They also do not say that they coincide at turn 20.

If we continue, we can calculate when they coincide again:

1st

20 + 4 = 24

20 + 5 = 25

2nd

24 + 4 = 28

25 + 5 = 30

3rd

28 + 4 = 32

30 + 5 = 35

4th

32 + 4 = 36

35 + 5 = 40

5th

36 + 4 = 40

They therefore coincide again at turn 40.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
