6 ribbon each 1/4 yard long how many yards of ribbon?

We can multiply 6 by 1/4 to get the total amount since theres 6 ribbons:

6 * 1/4 = 1.5

1.5 yards long

Total distance traveled in ninth second is:

289 feet.

Step-by-step explanation:

The distance (in feet) that the projectile traveled each second, starting with the first second, was given by the arithmetic sequence :

17, 51, 85, 119, ...

i.e. we have:

Since,

where d represents the common difference of the sequence.

Hence, the ninth term of the sequence is the total distance that the projectile traveled in the ninth second i.e.

Hence, the total distance traveled in the ninth second is:

289 feet.
