Justin bought some yarn from his Favorite craft store. He can make one score for 3/5 of a ball of yarn. If he purchases 15 balls
Svet_ta [14]

Justin can make 25 scraves with 15 balls of yarn

<h3><u>Solution:</u></h3>

Given that Justin can make one scarve for 3/5 of a ball of yarn

He purchases 15 balls of yarn

<em><u>To find: number of scarves Justin can make</u></em>

Number of scarves Justin can make with 15 balls of yarn can be found out by dividing 15 balls of yarn by 3/5 of a ball of yarn

\text {number of scarves }=\frac{\text { total yarn he has }}{\text { yarn needed for } 1 \text { scarve }}

\text {number of scarves }=\frac{15}{3 / 5}

\text {number of scarves }=\frac{15}{3} \times 5=25

Thus he can make 25 scraves

Given the geometric sequence where a1 = 2 and the common ratio is 4, what is the domain for n?
Karo-lina-s [1.5K]
The general term is a_n (a sub n; n is a subscript)

The first term is a1
The second term is a2
The third term is a3
and so on...

The first term starts at n = 1. We replace the n in a_n with 1 to get a_1. A similar thing happens with n = 2 and onward

The domain is therefore the set {1, 2, 3, 4, 5, ...} which is the set of...
* Counting numbers
* Positive Whole numbers
* Natural numbers
Those are three ways to express the same set

We can also say n \ge 1 where n is an integer or whole number
A similar inequality would be n \ \textgreater \ 0 which is effectively the same as idea as the last inequality (n is also an integer or whole number).
