Answer:
5
Step-by-step explanation:
for the first gear
revolutions/teeth
1 / 24
2 / 48
3 / 72
4 / 96
5 / 120
6 / 144
for the second gear
revolutions/teeth
1 / 40
2 / 80
3 / 120
4 / 160
<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>
the way to get that amount of teeth is


the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

120 teeth are 5 revolutions for gear1 and 3 por gear2
1/12 of a pound.
you must use the reciprocal of 4, 1/4, then multiply. so 1/3*1/4= 1/12
Answer:
an event with no possible outcomes
Step-by-step explanation:
because there is only one posible thing that can happen
5/2 inches per month * t = 15/4 inches
<span>t = ( 15/4 ) / ( 5/2) </span>
<span>t = 1.5 months</span>
Answer:
False
Step-by-step explanation:
3x4=12
12 divided by 3=4
4x8=32
32=34
Hence, this equation is false.
