Which expression is equivalent to 15 (n+3/n) ? £ N=10

Alika [10]

Answer:

$\sum_{n=10}^{15}(n+\frac{3}{n})=\sum_{n=10}^{15} n + \sum_{n=10}^{15} \frac{3}{n}$

Step-by-step explanation:

Given expression : $\sum_{n=10}^{15}(n+\frac{3}{n})$

Solving further:

$\sum_{n=10}^{15}(n+\frac{3}{n})$

$\Rightarrow \sum_{n=10}^{15} n + \sum_{n=10}^{15} \frac{3}{n}$

So, $\sum_{n=10}^{15}(n+\frac{3}{n})=\sum_{n=10}^{15} n + \sum_{n=10}^{15} \frac{3}{n}$

So, Option A is true

Hence the given expression is equivalent to Option A

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other. Find the length of the other piece

sergeinik [125]

Answer:

The length of the other piece is 38 inch.

Step-by-step explanation:

Given:

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.

Now, to find the length of the other piece.

Let the length of the other piece be $x$ .

And the length of one piece be $4x$ .

The total length of the pipe = $190 inch$

According to question:

$4x+x=190$

⇒ $5x=190$

Dividing both sides by 5 we get:

⇒ $x=38$

Therefore, the length of the other piece is 38 inch.
