Answer:
b. 15.39 L
Step-by-step explanation:
Given;
reacting mass of the Nitrogen gas N₂, m = 42 g
pressure of the gas, P = 2 atm
temperature of the gas, T = 250 K
molar mass of Nitrogen, N = 14 g/mol
molar mass of Nitrogen gas N₂, M = 28 g/mol
number of moles of the given Nitrogen gas;
[tex]n = \frac{Reacting \ mass}{Molar \ mass} = \frac{m}{M} \\\\n = \frac{42 \ g}{28 \ g/mol} = 1.5 \ mol.[/tex]
The volume occupied by the Nitrogen gas can be calculated from Ideal gas law;
PV = nRT
where;
V is the volume of the gas
R is ideal gas constant = 0.0821 atm.L / mol.K
From the equation above, make V the subject of the formula;
[tex]V = \frac{nRT}{P} \\\\V = \frac{1.5\ mol. \ \times \ 0.0821 \ atm.L/mol.K \ \times \ 250 \ K}{2 \ atm} \\\\V = 15.39 \ L[/tex]
Therefore, the volume occupied by the Nitrogen gas is 15.39 L

The period of an function, is how many times it takes to complete one cycle, if the period is 2π then after 2π the function would have been completed one entire cycle, but what I mean by cycle?
It's when the function start again, these functions are called periodic functions for a reason, after between that interval, the function goes up, goes to 0 again, go down and finally goes zero again, it means a cycle! the function goes up, down and then return to the same point.
If you look at the picture, the function took 2π just to go up and zero, it needs more 2π to go down and return to zero, then it's period is 4π.
The bottom function complete its cycle in just π!

A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression
(0.85).32 represents the final price of the cake in dollars.
Answers
Answer:
$27.2
Step-by-step explanation:
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars.
This is explained in the calculation below
= A cake that costs $32 is on sale for 15% off
The amount off the cake is calculated as
= 15% of $32
= 15/100 × 32
= $4.8
The amount he is paying for the cake =>$32 - $4.8
= $27.2
The above expression is obtained as
(0.85).32
= (100% - 15%) × 32
=( 1 - 0.15) × 32
= 0.85 × 32
= $27.2
The final price of the cake = $27.2

Answers
Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°
find the measure of angle A
Answers
Answer:
30
Step-by-step explanation:
Right angle = 90 degrees
180-90 = 90, hence the right side of the equation.
x+37+x+67 = 90
2x + 104 = 90
2x = -14
x = -7
Plug in x.
-7+37 = 30 (angle a)
Angle a = 30
Answer:
angle A = 30 degrees
Step-by-step explanation:
*All triangles have an interior angle that adds up to 180 degrees
The triangle is the picture is a right triangle so one of the angles is 90 degrees.
First, we must figure out what "x" is:
⇒ 180 = 90 + x + 37 + x + 67
Combine like terms:
⇒ 180 = 2x + 194
Subtract 231 from both sides:
⇒ 180 - 194 = 2x + 149- 194
⇒ -14 = 2x
The divide both sides by 2:
⇒ [tex]\frac{-14}{2} + \frac{2x}{2}[/tex]
⇒ -7 = x
Now, we can figure out what angle A is by taking the equation "x + 37" and subtituting x by -7:
⇒ x + 37
⇒ -7 + 37
⇒ 30
To check out answers, take all of the eqautions in the picture and subtitute x by -7, (remember that it must add up to 180):
⇒ 90 + x + 37 + x + 67 = 180
⇒ 90 + (-7) + 37 + (-7) + 67 = 180
⇒ 180 = 180

You spent $88.50 at target you happen to have $25 gift card from your birthday if the sales tax rate was 6.5% how much did you end up paying total?
Answers
$88.50 plus tax is $88.50 + ($88.50x6.5%, which equals $5.75 in tax)
$88.50 + $5.75 = $94.25 total with tax
If you have a $25 gift card, subtract that from your total with tax:
$94.25-$25.00=$59.25 total after you add tax and subtract the gift card
Hey can u help with the following questions because I don't get this.
Answers
Answer:
median- 58.5
first quartile- 56
third quartile- 65
interquartile range- 9
Step-by-step explanation:
median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)

Ms. Hardy walks 12 meters in 24.7 seconds.
If she walks at this same rate, which of the
following is closest to the distance she will
walk in 5 minutes?
Answers
Answer:
she walks about 145.7 meters in 5 minutes
Step-by-step explanation:
Hey There!
so first we want to find the meters per second rate
to do this we do
[tex]\frac{12}{24.7} = 0.48582995951[/tex]
so the meters per second is 0.4858299591
Then we want to find how many seconds are in a 5 minutes
to do this we multiply 5 and 60
5x60=300
then we want to multiply that by the meters per second
300x 0.4858299591=145.748987854
so she walks about 145.7 meters in 5 minutes

Answers
Answer:
it appears the answer options are typed incorrectly
Step-by-step explanation:
First of a line perpendicular to another line has the inverse opposite slope
if m is the slope m of line 1 the perpendicular line slope is -1/m
y - 3 = -4(x + 2) equarion 1
y - 3 = -4x - 8 -4 × (x+2)
y = -4x - 5 added 3 to both sides to get the y intercept form y=mx+b
the slope of the perpendicular line will be 1/4
using the point slope method
y - y1 = m(x -x1)
the gives the (x,y) point of the perpendicular as (-5, 7)
x1 = -5
y1 = 7
y - 7 = 1/4(x - (-5))
y - 7 = 1/4(x +5) <-------------- Answer
the attached graph shows the line and the perpendicular going through point (-5, 7)
