oxygen is the gas we breathe in . it can be separated from the air . it boils at - 219C and freezes at - 183 C.
A: in which state is oxygen, at: İ) 0 8C ? İİ)-200 C ?
B: how would you turn oxygen gas into solid oxgyen ?
Oxygen gas can be converted to solid, by the following two steps: By cooling or decreasing the temperature below the boiling point(-183°C) of oxygen
What are boiling and freezing temperature?The temperature at which the pressure of the vapour phase equals the atmospheric pressure is known as the boiling point.
The phase transition of a material from a liquid state to a solid state is referred to as freezing. This occurrence is known as a phase transition, which occurs when a material changes from one state of matter to another.
Given, oxygen is the gas we breathe . It can be separated from the . it boils at - 219C and freezes at - 183 C.
For in which state is oxygen, at:-200 C
Since, -200 falls between -219 and -183
Oxygen will at its liquid state at -200c temperature.
For to turn oxygen into solid State,
Oxygen gas can be converted to solid, by the following two steps: By cooling or decreasing the temperature below the boiling point(-183°C) of oxygen. This will cause the steam or gas of oxygen to condense into liquid oxygen. This process of conversion of a gas to its liquid state is called condensation.
Therefore, at -200 oxygen will at its liquid state.

Answer:
∠DBC
Step-by-step explanation:
Since ∠ABD shares the same vertex and side with ∠DBC, then they are adjacent angles.
place the following in order from greatest to least:
0.5001, 0.501, 5/100
Answer:
0.501, 0.5001, and 0.05
Step-by-step explanation:
0.501 is the greatest number since it is the closest to 1. 0.5001 is second since it has the 1 at the ten-thousandths. Finally is 0.05 because, again, it has no numbers close to 1 so it is the least.

Evaluate the function.
f(x) = 2x2
Find f(-3)
Answer:
Step-by-step explanation:
You have to understand two things about this question.
f(x) is a relative of y. So maybe it would help you if you wrote y = 2x^2The second thing you have to understand is when you see a number used instead of the x, that number goes into every x on the right.f(-3) = 2(-3)^2
f(-3) = 2 * 9
f(-3) = 18
Remember that (-3) ^2 = -3 * - 3 = 9 a positive.

(9 + 2i)(9 - 2i)
Answer:
It can't be expressed in that form
Step-by-step explanation:
From difference of two squares:
[tex]{ \boxed{(a + b)(a - b) = ( {a}^{2} - {b}^{2} )}}[/tex]
a » 9
b » 2i
[tex](9 + 2i)(9 - 2i) = \{ {(9)}^{2} - {(2i)}^{2} \} \\ \\ = (81 - 4 {i}^{2} )[/tex]
but i² is -1 [ complex numbers ]
[tex] = \{81 - 4( - 1) \} \\ = 81 + 4 \\ = 85[/tex]
Answer:
[tex](9 + 2i)(9 - 2i) \: \\ this \: can \: be \: wrtten \: as \: \\ {9}^{2} - {2i}^{2} = 81 - 4 \times - 1 \\ = 81 + 4 = 85 \\ then \: 85 + 0i \\ thank \: you[/tex]

Mr Patel drew figure A and its image figure k on the grid Amelia says figure k is a rotation of figure A Kareem says it is a reflection can both students be correct explain
Transforming figure A into k requires some methods. Therefore, both reflection and rotation could be applied. Thus both students are right.
Rigid transformation is a method required in resizing or changing the orientation of a given shape. The types are: translation, reflection, rotation and dilation.
Considering figure A and its image k given in the question, transformation has occurred. Reflection is the process of flipping a given figure about a reference line or a point. Thus Kareem is right if A is turned over the line joining A and k.
Secondly, rotation implies turning a given shape through a certain angle to form its image. Thus if figure A is turned clockwise or counterclockwise about the mid point of the line joining A and k, then Amelia is right.
It can be said that both students could be right.

Answer:
66°
Step-by-step explanation:
There are so many ways to get this answer. Angle seven and 5 are vertically opposite so they're equal. Angles 4 and 5 are co-interior so they add up to 180°. If 180 is the total of 4+5, and 5 is 114 then 4 = 180-114 which is 66.
Angles 7 and 3 are corresponding and corresponding angles are the same. 3 and 4 are on a straight line so they add up to 180. 180-114= 66
You can also use angles 8,6 and 2 to get your answer
Adam has five blue pencils how many red pencils what do you need to have that the ratio of blue pencil is 1:2
Answer:
10 red pencils because 10 is double 5 so it would be 5:10 which simplifies to 1:2
Answer:
10
Step-by-step explanation:
ratio 1 : 5
for 5 blue pencils ratio = 1
x red pencils ratio. = 2
simply 5B = 1
xR = 2
5B × 2 = R
R = 10
Therefore 10 red pencils are required
On a number line, point S is located at -3 and point T is located at 9. What is the location of point R on ST given that the ratio of SR to RT is 3:4
A) 27/7
B) 2 1/4
C) 15/7
D) 1 1/4
Answer:
Im pretty sure it would be C
Step-by-step explanation:
The location of R on the number line will be 15/7 so option (C) will be correct.
What is a number line?In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Distance from S to T = 3 + 9 = 12
So,
SR + RT = 12
And given,
SR/RT = 3/4 ⇒ SR = (3/4)RT
By substitution,
(3/4)RT + RT = 12
RT ( 7/4) = 12
RT = 48/7
Now the location of point R ⇒
OT - RT = 9 - 48/7 = 15/7
Hence "The location of R on the number line will be 15/7".
