60/4=15
105/15=7
Therefore the length is 7 inches

\frac{4}{x}  x   \frac{60}{105}

105 x 4 =60x
420 = 60x ( Divide 60 on both sides to get x by itself)
7 = x

The length should be 7 inches 

Hope this helps :)

What is (43/7÷ x+32/9) ÷25/6=4/3
Fittoniya [83]

The value of x in the equation (43/7 ÷ x + 32/9) ÷ 25/6 = 4/3 is 43/14

<h3>How to solve for x in the equation?</h3>

The equation is given as:

(43/7 ÷ x + 32/9) ÷ 25/6 = 4/3

Rewrite as a product

(43/7 ÷ x + 32/9) x 6/25 = 4/3

Multiply both sides of the equation by 25/6

(43/7 ÷ x + 32/9)= 4/3 x 25/6

Evaluate the product

(43/7 ÷ x + 32/9)= 50/9

Rewrite the equation as:

43/7x + 32/9= 50/9

Subtract 32/9 from both sides

43/7x = 2

Multiply both sides by 7x

14x = 43

Divide by 14

x =43/14

Hence, the value of x in the equation (43/7 ÷ x + 32/9) ÷ 25/6 = 4/3 is 43/14

Question is from definite integral.
Karolina [17]

Answer:

The value of the sum is: $ \frac{\pi}{4} $.

Step-by-step explanation:

Given: $ \lim_{n \to \infty} \displaystyle \sum_{k = 1}^ {n} \bigg ( \frac{n}{n^2 + k^2} \bigg ).

Taking $ n^2 $ common outside from the denominator, we have:

$ \bigg ( \frac{n}{(n^2)(1 + (\frac{k^2}{n^2})} \bigg )

\implies\frac{1}{n} .\frac{1}{1 +\big (  \frac  {k^2}{n^2}\big )}

We have the following theorem.

If $f $ is integrable on [0, 1] then $ \int _{0}^{1} f(x) dx = \lim_{n \to \infty} \frac{1}{n} \displaystyle \sum_{r = 1}^{n} f( \frac{x}{n})    $.

Now, let $ \frac{k}{n} = x $

$ \implies dx = \frac{1}{n} $.

Therefore the summation becomes

$ = \int_{0}^{1} \bigg ( \frac{1}{1 + x^2} \bigg )

$ \implies \tan^{-1}(x)|_{0}^{1} $

$ \implies tan^{-1}(1) - tan^{-1}(0) $

$ = \frac{\pi}{4}  - 0 $

$ = \frac{\pi}{4} $

Hence, the sum is $ \pi $/4.

(help i got 6 mins) Find the slope and y intercepts <br> No bots or i will report
IgorLugansk [536]

Answer:

the slope is 7

y intercept is -4

Step-by-step explanation:

y-y1 = m(x-x1)

m = (y2-y1) / (x2-x1)

m = (10-3)/(2-1)

m=7/1

y-3=7(x-1)

y-3=7x-7

y=7x-7+3

y=7x-4
