A 60-cm spring will stretch (in cm) one third the weight (in kg) attached to it. How long will the spring be if a 20-kg weight is attached?

9514 1404 303

  66 2/3 cm

Step-by-step explanation:

The weight in kilograms is 20, so the stretch in cm is 20/3 = 6 2/3 cm.

When the 60 cm spring is stretched an additional 6 2/3 cm, its length will be ...

  60 +6 2/3 = 66 2/3 . . . cm

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
