Part = percent/100 * whole 20 = x /100*50 X = 2000/50 X= 200/5 =40%

Answer:

<h2>20 represents a 40% of 50.</h2><h2>The percentage is 40.</h2><h2>The base is 50.</h2><h2>The amount is 20.</h2>

Step-by-step explanation:

Observe that we want to find the percentage that the number 20 represents where 50 is the total.

The fatest way to solve this problem is by dividing

$\frac{20}{50}= 0.4$

Then, we multiply by 100, to express it in percetange

$0.4 \times 100\%=40\%$

Therefore, 20 represents a 40% of 50.

The percentage is 40%.
The base is 50, which represents 100%.
The amount is 20.

If we express each element, it would be

$40\% \times 50=20$

2. For the following, is the stated conclusion reasonable? Why or why not?

lapo4ka [179]

Answer:

Definetely, it is reasonable. You may assume that a pet as a companionship will help the elderly feel more comfortable and therefore, happy. There are a few problems tough:

There is no practical way of meassuring 'happiness'.
Sometimes, the correlations of two factors may be a coincidence. Scientist should always consider this when they try to claim something byusing some backup logic, like we did.
Even tough the statement makes some sense, you need to be aware that maybe is not completly positively correlated. Maybe having 20 more pets does not make an elderly happy if it alredy had 1 or 2.

the answer is b. I'm pretty sure at least because the square root it roughly 5.91 and that's between 5 and 6.
