The similar triangles have adjacent angles A and R to be supplementary and value of the variable x is equal to 11. The angles m∠A = 106°, m∠R = 74°, and m∠S = 58°
How to evaluate for variable x of the adjacent anglesThe triangles RDS and ADB area similar thus the lines AB and RS are parallel to each other and the adjacent angles of m∠SRA and m∠BAR are supplementary, so their sum is equal to 180°.
m∠SRA and m∠BAR are supplementary so;
(6x + 8)° + (9x + 7)° = 180°
15x + 15 = 180°
15x = 180° - 15 {subtract 15 from both sides}
15x = 165
x = 165/15 {divide through by 15}
x = 11
m∠A = 9(11) + 7 = 106°
m∠R = 6(11) + 8 = 74°
m∠S = 4(11) + 14 = 58°
Therefore, the similar triangles have adjacent angles A and R to be supplementary and value of the variable x is equal to 11. The angles m∠A = 106°, m∠R = 74°, and m∠S = 58°

16 lakh students in India use Khan Academy today. The number of users is expected to grow by 50% every year. How many students in India will be using Khan Academy two years from now?
Answer: Let's first calculate the number of users after one year:
Number of users after one year = 16 lakh + 50% of 16 lakh
= 16 lakh + 8 lakh
= 24 lakh
Now, we can calculate the number of users after two years by applying the same growth rate:
Number of users after two years = 24 lakh + 50% of 24 lakh
= 24 lakh + 12 lakh
= 36 lakh
Therefore, two years from now, it is expected that 36 lakh (3.6 million) students in India will be using Khan Academy.

4. Claire jogs around an oval track and is able to complete one lap in 5 minutes.
If she jogs at the same pace for 42 minutes, how many laps would she be able
to jog? Write an inequality and find the number of whole laps Claire completes.
The inequality that represent how many laps she can do is "number of laps < 8.4".
Claire can jog a maximum of 8 laps in 42 minutes.
What number of whole laps did Claire completes?Since Claire can jog one lap in 5 minutes, we can use division to find how many laps she can complete in 42 minutes:
= 42 minutes / 5 minutes per lap
= 8.4 laps
However, since Claire cannot jog a fractional number of laps, we need to round down to the nearest whole number of laps. This is because she will have only completed a fraction of a lap by the time she reaches the end of the 42 minutes, and we want to know how many whole laps she completes. Therefore, we can write the inequality as "number of laps < 8.4".

Mary Jo spends $2,300 to buy stock in two companies. She pays $19 a share to one of the companies and $24 a share to the other. If she ends up with a total of 100 shares, how many shares did she buy at $19 a share and how many did she buy at $24 a share?
She bought ____ shares at $19 and ___ shares at $24.
Answer:
Mary Jo bought 20 shares at $19 a share and 80 shares at $24 a share.
Step-by-step explanation:
Let's use algebra to solve the problem. Let x be the number of shares Mary Jo buys at $19 a share, and y be the number of shares she buys at $24 a share.
We know that Mary Jo spends a total of $2,300, so we can write the equation:
19x + 24y = 2300
We also know that she ends up with a total of 100 shares, so we can write the equation:
x + y = 100
Now we have two equations with two variables, which we can solve using substitution or elimination.
Let's use substitution. Solve the second equation for x:
x = 100 - y
Substitute this expression for x in the first equation:
19(100 - y) + 24y = 2300
Simplify and solve for y:
1900 - 19y + 24y = 2300
5y = 400
y = 80
So Mary Jo bought 80 shares at $24 a share.
To find the number of shares she bought at $19 a share, substitute y = 80 in the second equation:
x + 80 = 100
x = 20
Therefore, Mary Jo bought 20 shares at $19 a share.
In summary, Mary Jo bought 20 shares at $19 a share and 80 shares at $24 a share.
Show that multiplication this following:
Since AB and BA are not equal for n > 1, we have shown that multiplication in M_n(R) is not commutative for n > 1.
How to solveTo show that multiplication in M_n(R) is not commutative when n > 1, we need to find two matrices A and B in M_n(R) such that AB is not equal to BA.
Let's consider two matrices A and B in M_n(R) such that:
A = [a_ij], where a_ij = 1 if i=j, and a_ij = 0 otherwise.B = [b_ij], where b_ij = 1 if i+j = n+1, and b_ij = 0 otherwise.That is, A is the n x n identity matrix, and B is the matrix with 1's on the anti-diagonal and 0's elsewhere.
Now let's compute AB and BA:
AB = [c_ij], where c_ij = Σ_k=1^n a_ik * b_kj
If i+j = n+1, then b_kj = 1 only if k = i, and a_ik = 1 only if k = j.
Therefore,
c_ij = a_i1 * b_1j + a_i2 * b_2j + ... + a_in * b_nj = a_ii * b_jj = 1 * 1 = 1
If i+j ≠ n+1, then b_kj = 0 for all k, and hence c_ij = 0.
Therefore, AB is the matrix with 1's on the anti-diagonal and 0's elsewhere, just like B.
Now let's compute BA:
BA = [d_ij], where d_ij = Σ_k=1^n b_ik * a_kj
If i=j, then a_kj = 1 only if k = i, and b_ik = 1 only if k = i. Therefore,
d_ij = b_i1 * a_1j + b_i2 * a_2j + ... + b_in * a_nj = b_ii * a_jj = 1 * 1 = 1
If i ≠ j, then a_kj = 0 for all k, and hence d_ij = 0.
Therefore, BA is the matrix with 1's on the diagonal and 0's elsewhere, just like A.
Since AB and BA are not equal for n > 1, we have shown that multiplication in M_n(R) is not commutative for n > 1.

Tan^2a-cosec^2a+1=0 value of pie
the solutions for a are:
a = n×π, π/4, or 7π/4, where n is any integer.
define integerAn integer is a whole number that can be positive, negative, or zero, but does not include fractions or decimals.
tan²(a) - csc²(a) + 1 = 0
tan²(a) - (1/sin²(a)) + 1 = 0
(tan²(a)sin²(a) - 1 + sin²(a))/sin²(a) = 0
Simplifying the numerator:
(tan²(a) - 1)sin²(a) = 0
Using the identity tan^2(a) = sec²(a) - 1:
(sec²(a) - 2)sin²(a) = 0
Expanding and simplifying:
sec²(a)sin²(a) - 2sin²(a) = 0
sin²(a)(sec^2(a) - 2) = 0
So either sin²(a) = 0 or sec²(a) - 2 = 0.
If sin²(a) = 0, then a is an integer multiple of pi (i.e., a = n×π for some integer n).
If sec²(a) - 2 = 0, then sec²(a) = 2,
cos(a) = ±√(2)/2
So a can be π/4 or 7π/4.
Therefore, the solutions for a are:
a = n×π, π/4, or 7π/4, where n is any integer.

What is the angle of elevation when little Judy looks at her red balloon?
The answer of the given question is (3) the length of the run of the Mighty Drop ski slope is approximately 181.8 feet. (4) the angle of elevation when little Judy looks at her red balloon is approximately 82.7°.
What is Slope?A slope typically refers to the angle of an incline or ramp, or the ratio of vertical change to horizontal change of a straight line or curve on a graph. For an incline or ramp, the slope is the angle between the surface and the horizontal plane. It is defined as the ratio of the vertical rise to the horizontal run of the ramp.
In the context of a graph, slope refers to the steepness of a line or curve. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line or curve. The slope of a line can be positive (if the line goes up from left to right), negative (if the line goes down from left to right), or zero (if the line is horizontal).
(3) . To solve for the length of the run of the Mighty Drop ski slope, we can use the trigonometric function tangent, which relates angle of elevation to ratio of opposite and adjacent sides of right triangle.
Let x be the length of the run. Then we have:
tangent(75°) = opposite/adjacent
tangent(75°) = 800/x
Solving for x, we get:
x = 800 / tangent(75°)
x ≈ 181.8 feet
Therefore, the length of the run of the Mighty Drop ski slope is approximately 181.8 feet.
(4) . To solve for the angle of elevation when little Judy looks at her red balloon, we can use the trigonometric function arctangent.
Let θ be the angle of elevation. Then we have:
tangent(θ) = opposite/adjacent
tangent(θ) = 2240/350
Taking the arctangent on both sides, we will get:
θ = arctangent(2240/350)
θ ≈ 82.7°
Therefore, the angle of elevation when little Judy looks at her red balloon is approximately 82.7°.

What is equation?A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A mathematical statement that proves the equality of two mathematical expressions is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two sentences that are written on opposite sides of a letter.

The slοpe οf the graph οf Pt represents the rate οf change οf the pοpulatiοn οver time, and its value tells us hοw fast the pοpulatiοn is grοwing οr declining.
What is the slοpe?The slοpe οf a line is a measure οf its steepness. Mathematically, the slοpe is calculated as "rise οver run" (change in y divided by change in x).
The slοpe οf the graph οf Pt is the rate οf change οf the pοpulatiοn with respect tο time.
Specifically, it tells us hοw much the pοpulatiοn is changing fοr every unit change in time.

A sealed, inflated balloon is placed into a flask of liquid nitrogen at a temperature of 77 k. The ballon begins to shrink and shrivel up. Use gas particle motion to explain why.
This causes the volume of the balloon to decrease, leading to an increase in the number of collisions between gas particles and the inside surface of the balloon, and causing the balloon to shrink and shrivel up.
What is temperature?Temperature is a measure of the average kinetic energy of the particles in a substance or system. In other words, it is a measure of how hot or cold something is relative to a standard reference point. The SI unit of temperature is the kelvin (K), but temperature is often measured in degrees Celsius (°C) or Fahrenheit (°F) in everyday life. Temperature plays a crucial role in many natural and man-made processes, and is a key factor in determining the behavior of matter at different states.
Here,
When a sealed, inflated balloon is placed into a flask of liquid nitrogen at a temperature of 77 K, the gas particles inside the balloon lose thermal energy and slow down. As the temperature drops, the average kinetic energy of the gas particles decreases, causing them to move slower and collide less frequently. This results in a decrease in pressure inside the balloon.
According to the Ideal Gas Law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin. As the pressure inside the balloon decreases, its volume also decreases, since the number of moles of gas and the gas constant remain constant.
Since the balloon is sealed, the gas particles cannot escape, so they continue to collide with each other and the inside surface of the balloon. As the volume of the balloon decreases, the gas particles become more crowded, increasing the number of collisions between them. This leads to a decrease in the distance between the gas particles and the inside surface of the balloon, causing the balloon to shrink and shrivel up.
In summary, when a sealed, inflated balloon is placed into a flask of liquid nitrogen at a temperature of 77 K, the gas particles inside the balloon lose thermal energy, slow down, and collide less frequently, resulting in a decrease in pressure inside the balloon.

PLEASE PLEASE PLEASE HELP!
Answer:
w-4
Step-by-step explanation:
Suppose we going to find⊕
(4-w)÷(-w-9 ) =⊕÷(w+9 )
⇒(4-w) ÷ -(w+9) =⊕÷(w+9)
cross-multiply we will get
∴ ⊕={(4-w)×(w+9)}÷-(w+9)
= -(4-w) after cancelling ( w+9)
therefore our answer is ( w-4 )
