What percent is $10,000 out of a 120.000
Svetlanka [38]
10,000 is 8.33% of 120,000.

10,000 / 120,000 = 0.0833 * 100% = 8.33%

Assuming that the whole and percentage is given. find the value of the percentage.

120000 * 8.33% = 9996 ⇒ 10,000

If the percentage is given and its corresponding value. find the whole

10,000 / 8.33% = 120,048 ⇒ 120,000

Pls help me to answer this​
Flauer [41]

Answers:

T-shirt = $25

Shorts = $15

Books = $50

Shoes = $30

Cell phones = $750

===============================================

Explanation:

Taking 10% of a number is simply moving the decimal point over one spot to the left.

For example, the selling price of a t-shirt is $250.00 and taking 10% of this gets us to $25.00

As another example, 10% of 150.0 is 15.0

If a whole number ends with a 0, then taking 10% of the number means we chop that zero off.

Let f(x) and g(x) be polynomials as shown below. Which of the following is true about f(x) and g(x)? f(x) and g(x) are not close
Mrrafil [7]

Answer:

  f(x) and g(x) are closed under multiplication because when multiplied, the result will be a polynomial.

Step-by-step explanation:

The set of all polynomials is <em>closed</em> under addition, subtraction, and <em>multiplication</em>, because performing any of these operations on a pair of polynomials will give a polynomial result.

__

<em>Comment on the question</em>

The wording is a bit strange, because f(x) and g(x) are elements of a set (of polynomials), so cannot be said to be "closed." "Closed" is a property of a set with respect to some function, it is not a property of an element of the set.

Why is the percent increase of 45 to 75 not equal to the percentage crease of 75 to 45 check all that apply.
nevsk [136]

Answer: B and F

Step-by-step explanation:

Since, In the first case original amount = 45

So, the increasing percentage when the original amount increases to 75,

=  \frac{75-45}{45} \times 100 = \frac{30}{45} \times 100= \frac{200}{3} %

In second case original amount = 75

So the decreasing percentage when the original amount decreases to 45,

=    \frac{75-45}{75} \times 100 = \frac{30}{75} \times 100= \frac{40}{1} %

Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,   \frac{200}{3}\neq \frac{40}{1}

Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because, 75\neq 45

Therefore, Option B and F is correct only.
