A water molecule is made up of 3 atoms. One third of the atoms are oxygen and the remaining atoms are hydrogen. If there are 114
Mashcka [7]

Answer:

228 hydrogen atoms

Step-by-step explanation:

In a water molecule,

1/3rd is oxygen atoms, and

2/3rd (1 - 1/3 = 2/3) is hydrogen atoms

If there are 114 water molecules,

Total number of atoms would be:

3 * 114 = 342 (1 oxygen and 2 hydrogen atoms in 1 water molecule)

Out of these, 2/3rd would be hydrogen atoms, so:

\frac{2}{3}*342=228

There would be 228 hydrogen atoms

What is this question pls?
beks73 [17]

Answer:

58 degrees

Step-by-step explanation:

Diagonals in a rhombus bisect each other perpendicularly.

=> mXYW = 90 degrees

and mXWY = 32 degrees

Because XYW is a triangle

=> mWXY = 180 - 90 - 32 = 58 degrees

Which graph represents the piecewise function?<br><br><br>x+3   if  x&lt;0<br><br>2x if x ≥ 0
kolbaska11 [484]

Answer:

Graph 1 will be the correct one.

Step-by-step explanation:

We are given the piece wise function defined as  

f(x) = x + 3 for x < 0 and f(x) = 2x for x ≥ 0

The first part of the function does not include x = 0.

And, this is in slope-intercept form.

So, slope is 1 i.e. tan Ф = 1, ⇒ Ф = 45°.

And it has y-intercept at (0,3).

So, the conditions are shown in graphs 1 and 3.

Now, the second part of the function equation passes through origin {As the equation is f(x) = 2x}

So, only graph 1 matches both the conditions.

Therefore, graph 1 will be the correct one. (Answer)

Solve the equation (x-2)^2/3=9
statuscvo [17]

Answer:

x = 2±3sqrt(3)

Step-by-step explanation:

(x-2)^2/3=9

Multiply each side by 3

(x-2)^2/3 *3=9*3

(x-2)^2=27

Take the square root of each side

sqrt( (x-2)^2)=±sqrt(27)

x-2 = ±3sqrt(3)

Add 2 to each side

x = 2±3sqrt(3)
