Answer:

The weighted average is the sum of each individual nuclide, multiplied by its isotopic abundance.

the average atomic mass of the chlorine sample =

0.7576 × 34.969  +  0.2424 × 36.966  =  35.45 of Cl-35  amu

Flauer [41]

Answer:

y=2 when x=2

Step-by-step explanation:

3(2)=6

6+6y=18

6y=18-6

6y = 12

6y/6 = 12/6

if one card is drawn from a regular deck of cards, what is the probability the card will not be an ace?
satela [25.4K]

There are 52 cards in a deck of cards so that makes 52 your denominator. There are 4 aces in a deck of cards, so 52 - 4 = 48 making 48 your numerator. so the probability the card won't be an ace is 48 out of 52.

48/52 chance that the card will not be an ace.

Hope this helps you. :-)

Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x
Agata [3.3K]

We can actually see that the statements that are true are:

A. x = 1 is a solution.

C. x = –1 is a solution.

<h3>What is rational equation?</h3>

Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.

We can see then that:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{x + 10}{ {x}^{3} + 6 {x}^{2}  }

It's clear that: x ≠ 0 and x ≠ -6.

Looking for the LCM of the left hand side, we will have:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{4 {x}^{2 }  + (x + 6)}{(x + 6) {x}^{2} }

So, we will see that left hand side and right hand side are equal.

4 {x}^{2}  + x + 6 = x + 10

4 {x}^{2}  = 10 - 6

4 {x}^{2}  = 4

{x}^{2}  = 1

x = 1

or

x =  - 1

So, we can see that options A and C are correct.
