Answers
Answer:
x = - 5, x = - 1
Step-by-step explanation:
Given
(x + 3)² = 4 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{4}[/tex] = ± 2 ( subtract 3 from both sides )
x = - 3 ± 2
Then
x = - 3 - 2 = - 5
x = - 3 + 2 = - 1

Another statement is, "Volume is directly proportional to the number of moles."
The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.
V

V

n

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.
STP is 0 °C and 1 bar.
One mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L
Example Problem
A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence

Sometimes life is tricky.
Sometimes things go wrong.
Sometimes you feel out of place
Or like you don't belong.
Sometimes bed things happen.
Sometimes you'll feel scared.
But focus on the positives;
Seek them, they'll be there.
When your brain won't stop whirring,
And you can't sleep at night,
Step out of the darkness
And look into the light.
The awful things won't vanish
Like thin air
But don't let them consume
That just makes you miserable
And intensifies the gloom.
So focus on your blessings
And let them shine through.
Don't let the negatives
Be what defines you :)
An amazing thing happens when you get honest with yourself and start doing what you love, what makes you happy. You stop merely looking forward to special events. You begin to live in each moment and you start feeling like a human being. You just ride the wave that is life, with this feeling of contentment and joy. You move fluidly, steadily, calm and grateful.
Hope this helps :)
Have a great day.

At a sale this week, a sofa is being sold for $272. This is a 36% discount from the original price. What is the original price?
Answers
Answer:
Step-by-step explanation:
A 36% discount means the selling price is (100-36)% = 64% of the original price.
$272 = 64% of x = 0.64·x
x = $272/0.64 = $425
What is 1102 using the polynomial identity (a+b)2=a2+2ab+b2 ?
Drag and drop the correct responses into the boxes.
Let the smaller value a = Response area and the larger value b = Response area. Then a2+2ab+b2 is Response area. This can be simplified to Response area. So, 1102 is equal to Response area.
Answers
Answer:
"Let the smaller value a = 10 and the larger value b = 100. Than a^2 + 2ab + b^2 is 10^2 + 2 * 10 * 100 + 100^2. This can be simplified to 12100. So, 110^2 is equal to 12100."
Hope this helped!
The smaller value is 10
The larger value is 100
So the square of 110 should be 12100
Calculation of the value:Since here we assume the smaller value be 10
So, the larger value be 100
Now
[tex]a^2 + 2ab + b^2 = 10^2 + 2 \times 10 \times 100 + 100^2.[/tex]
This can be simplified to 12100.
So, [tex]110^2[/tex] is equal to 12100.

Miguel is ordering 6 bags of cat food from Canada. Each bag has a mass of 7.5 kg. To determine the shipping costs, Miguel needs to know the total weight in pounds. What is the weight of the cat food in pounds? Use 1 kg = 2.2 lbs and do not round any computations.
Answers
Answer:
99 pounds
Step-by-step explanation:
7.5×6=45kg
1kg=2.2lb and we have 45kg because this is direct proportion what you do to one side you havbe to do to the other

A building manager
needs to order 9 replacement panes that are
all the same size, each similar to the window
itself. At what angles should each pane be cut
in order to fit in the window? What are the
dimensions of each pane? Explain.
96°
40.5 ft
42°
60 ft
Answers
Answer:
42,42,96
Step-by-step explanation:
The angles of each plane that must be cut to fit are 42°, 42°, and 96°.
The dimension of each plane is 13.4 ft, 13.5 ft, and 20 ft.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Two angles of the figure are:
96 and 42.
The sum of the angles in a triangle is 180°.
So,
The other angle.
= 180 - (96 + 42)
= 180 - 138
= 42
Now,
The angles of each plane must be cut in 42°, 42°, and 96°.
Now,
The side opposite to the equal angles is equal.
So,
The dimensions of the triangles are 40.5 ft, 40.5 ft, and 60 ft.
The dimensions of each plane.
= 40.5/3, 40.5/3, and 60/3
= 13.4 ft, 13.5 ft, and 20 ft.
Thus,
The angles of each plane are 42°, 42°, and 96°.
The dimension of each plane is 13.4 ft, 13.5 ft, and 20 ft.
