How many % of 50 shirts 35 shirts
vodka [1.7K]
Do you mean what percent is 35 of 50? I can help with that. Well since a percent is out of 100 you can multiply 50 by 2 to get to 100. But then you would also have to multiply 35 by 2. This will get you 70 out of 100. Which would make it 70 percent. Both number are proportionate so 70 would be your answer. But since this doesn't work for most others another way to solve it is to divide 35 by 50. And you get 0.7 Which it seventy-tenths of one hundred. Or 70 percent. So you could work this one both ways. But your final answer would be 70% no matter which you do.

HELP ME OUT !!!!!!!!!!!!!!!!!!!!!
Leona [35]

Answer:

y = -3x + 1

Step-by-step explanation:

  • Start by picking any two points on the line.

(-1, 4) and (1, -2)

  • Now, use the slope formula to find the slope.

m = y^2 - y^1 / x^2 - x^1

m = -2 - 4 / 1 - (-1)

m = -6 / 1 + 1

m = -6/2

m = -3

So, our slope is -3.

  • Let's find the y-intercept now using the slope-line equation:

y = mx + b

4 = -3(-1) + b

4 = 3 + b

-3   -3

---------------------

1 = b

  • Lastly, let's put our findings into the slope-line equation:

y = mx + b

slope is -3 and y-intercept is 1

y = -3x + 1

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.
