y = -1/3x + 1/4
This equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -1/3 and the y intercept is 1/4
Hello there! :)
y=-1/3x+1/4
-1/3 is the slope
Remember y=mx+b. m is the slope and b is the y-intercept.
Here, m (the slope) is -1/3, and the y-intercept is 1/4
Therefore, the slope is: [tex]-\frac{1}{3}[/tex]Hope this helps you!

Consider two identical containers, one contains 1.5 moles of nitrogen gas at 250K and the other contains 1.5 moles of nitrogen gas at 350K. Which of the following statements is TRUE? *
0 points
The pressure exerted by the nitrogen gas (N2) is the same in both containers
The average speed of the nitrogen gas (N2) molecules is higher in container #1 than in container #2
The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2
The average kinetic energy of the nitrogen gas (N2) molecules is the same in both containers
Answers
We want to see which of the given statements is true for the identical containers with nitrogen gas.
The correct statement is:
"The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2"
Remember the ideal gas equation:
P*V = n*R*T
Where P is the pressure, V is the volume, n is the number of moles, R is a constant, and T is the temperature.
Both gases are in identical containers, so both have the same volume. Also both containers have 1.5 moles of nitrogen, so n is the same number for both containers, and R is a constant, so it is the same for both.
The thing that is different is the temperature, for container 1 we have a temperature of 250K, while for container 2 we have a temperature of 350K, then we can write two pressure equations:
[tex]P_1 = \frac{n*R}{V}*(250k)\\\\P_2 = \frac{n*R}{V}*(350k)[/tex]
Where n*R/V is a constant term.
Then is really clear to see that the pressure exerted by nitrogen will be larger in container 2, because it increases linearly with the temperature and the temperature is larger in container 2.
Also remember that increases in temperature manifest as an increase in the kinetic energy of the molecules of the gas, thus, the container with a larger temperature will have molecules with larger kinetic energy (thus, larger mean velocity)
From the given statements, the only one that is true is:
"The rate at which nitrogen gas (N2) molecules collide with the container walls is lower in container #1 than in container #2"
This collision with the walls is a representation of pressure, this says that container 1 has less pressure than container 2, which is true.

A chemist want to mix a 40% acid solution with a 70% acid solution to make 6 liters of a 50% acid solution. How much of each type of solution should the chemist use? Show your Work. I NEED HELP ASAP, PLZ HELP
Answers
Answer:
2 liters of 70%
4 liters of 40%
Step-by-step explanation:
Let
x = liters of 70%
Then the remaining amount is
6 - x = liters of 40%
---------------------------------
Mixing
(70% of x) + (40% of 6 -x) (to get) 50% of 6)
70(x) + 40(6-x) = 50(6)
Simplify
70x + (240 - 40x) = 300
Combine like terms
30x = 60
Divde both sides by 30
x = 2 liters of 70%
6 - x = 4 liters of 40%
An angle measures 4.6° less than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
The two angles are,87.7° and 92.3°Step-by-step explanation:
Question,To find an angle and it's supplementary angle.
Let,The supplementary angle be = x
So, the angle given is = x - 4.6
As we know,When two angles added gives 180°, then those angles are called supplementary angles.
Therefore solution,By the problem,
=> x + (x - 4.6) = 180
[On adding like terms x]=> 2x - 4.6 = 180
[Putting - 4.6 to other side of equal to which converts to 4.6]=> 2x = 180 + 4.6 = 184.6
[On dividing 2 on both sides][tex] = > \frac{2x}{2} = \frac{184.6}{2} [/tex]
[On Simplification]=> x = 92.3
Result:So, the supplementary angle is = 92.3° (Ans)(ii)
And, it's required angle is = 180° - 92.3° = 87.7° (Ans)(i)
Supplementary Angles :
If the sum of the measures of two angles is 180°, then the angles are called supplementary angles and each angle is called a supplement of the other.⠀
Given :
An angle measures 4.6° less than the measure of its supplementary angle.⠀
To Find :
The measure of each angle.⠀
Solution :
Let's assume the one of the supplementary angle as "x" and the other angle as (x + 4.6)° .Now,
According to the Question :
[tex]\begin{gathered}\\ \sf x + (x - 4.6) {}^{ \circ} = 180{}^{ \circ} \\ \\ \dashrightarrow \: \sf x + x - 4.6{}^{ \circ} = 180{}^{ \circ} \\ \\ \sf \: \dashrightarrow 2x - 4.6{}^{ \circ} = 180{}^{ \circ} \: \: \: \: \\ \\ \dashrightarrow \sf \: 2x = 180{}^{ \circ} + 4.6{}^{ \circ} \\ \\ \dashrightarrow \sf \: 2x = 184.6{}^{ \circ} \: \: \: \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = \frac{184.6 {}^{ \circ} }{2} \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = 92.3 {}^{ \circ} \: \: \: \: \: \\ \\\end{gathered}[/tex]
Therefore,
One angle = 92.3°Other angle = 180° – 92.3° = 87.7°⠀
Hence,
The measure of the two angles are 92.3° and 87.7° .In the xy-coordinate plane shown, line L passes through point C and has a slope of -2. A dilation of line {with center A and a scale factor of 3 will

The solution is, New line slope will be -2 and, coordinates (-4. 2).
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
Dilation of a line about a point not on the line shifts the line but leaves the slope intact .
New line slope will be -2
As both A and C lie on a horizontal line y = 2, C' will also lie on the same line
The distance between A and C is 0 - 2 = -2
a scale factor of 3 means C' is -2(3) = -6 units left of A
C' = (2 - 6, 2)
= (-4. 2)
Hence, The solution is, New line slope will be -2 and, coordinates (-4. 2).

A colony of E. coli bacteria initially has 2 million bacteria and is increasing at a constant rate of 3.5% every minute. Write a formula for the number of bacteria in the colony after tt minutes.
Answers
The formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]
An exponential growth is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b > 1
Let y represent the bacteria population after t minutes
Given that initially has 2 million bacteria, hence:
a = 2 million = 2000000
It increases at a rate of 3.5% every minute, hence:
b = 100% + 3.5% = 1.035
The equation is:
[tex]y=2000000(1.035)^t[/tex]
Therefore the formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

MARK ME BRAINLIEST!!!Please help! In a tidal river, the time between high and low tide is 5.8 hours. At high tide, the depth of water is 17.2 feet, while at low tide the depth is 4.6 feet. Assume the water depth as a function of time can be expressed by a trigonometric function (sine or cosine).
Write an equation for the depth () of the tide (in feet) hours after 12:00 noon.
Answers
Answer:
Step-by-step explanation:
mean tide is (17.2 + 4.6)/ 2 = 10.9 ft
Amplitude of tide is (17.2 - 4.6)/ 2 = 6.3 ft
The full tide cycle is 2(5.8) = 11.6 hrs
As we are not told the tide condition at 12:00 noon,
I will ASSUME that the tide is high and use the cosine function
D = 10.9 + 6.3cos(2π(t/11.6)) ft
where t is in hours after noon high tide.
make sure your calculator is set to radians.
If you want to use degrees, the equation becomes
D = 10.9 + 6.3cos(360(t/11.6)) ft
