The length of TS in ΔTRS using Similarity of triange is 12 cm .
What is Similarity of Triangles ?If two items have the same shape or have the same shape as their mirror images, they are said to be Similar. One can be produced from the other more accurately by evenly scaling it, perhaps with the addition of further translation, rotation, and reflection.
If the sides are in the same ratio or proportion and the angles are equal (corresponding angles), two triangles will be comparable (corresponding sides). Similar triangles may have varying individual side lengths, but they must have equal angles and the same scale factor or matching ratio of the side lengths. If two triangles resemble one another, then
Triangles with similar angle pairings have all the same angles.Triangles have proportionate sides on all matching sides.In ΔTPQ and ΔTPS
∠T is common in both triangle
PQ ║ RS
∴∠TPQ = ∠TRS (Corresponding Angles)
similarly ,
∠TQP = ∠TSR
∴ Δ TPQ ~ ΔTRS

What is meant by length ?
The term "length" is used to describe an object's size or the separation between two points.For instance, the length of a ruler is revealed in the table below.The distance separating an object's ends is its length. The longest dimension is this one. The width of an object is the separation between its two sides. The shortest dimension is this one.Using measuring instruments like a ruler, measuring tape, etc., one may measure the length of any object. A ruler can be used to determine, for instance, how many inches a pencil is long. A foot scale can be used to gauge the height of each student in a class.In ΔTPQ and ΔTPS

7. Critique Reasoning Julio states that he can use the SAS Triangle Congruence
Theorem to prove that two right triangles are congruent. He constructs two right
triangles to have congruent hypotenuses and one set of congruent legs. What does
Julio need to do in order to use the SAS Triangle Congruence Theorem? Explain your
reasoning
Julio needs to prove that two sides of the two triangles are congruent, in addition to the hypotenuse and one set of legs that are already congruent, to use the SAS Triangle Congruence Theorem.
What is SAS Triangle Congruence Theorem?Congruence, in mathematics, a term employed in several senses, each connoting harmonious relation, agreement, or correspondence .Two geometric figures are said to be congruent, or to be in the relation of congruence, if it is possible to superpose one of them on the other so that they coincide throughout. Thus two triangles are congruent if two sides and their included angle in the one are equal to two sides and their included angle in the other.
This idea of congruence seems to be founded on that of a "rigid body," which may be moved from place to place without change in the internal relations of its parts. The position of a straight line (of infinite extent) in space may be specified by assigning four suitably chosen coordinates. A congruence of lines in space is the set of lines obtained when the four coordinates of each line satisfy two given conditions. For example, all the lines cutting each of two given curves form a congruence.

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 35% salt and Solution B is 60% salt. She wants to obtain 50 ounces of a mixture that is 55% salt. How many ounces of each solution should she use?
Answer:
Step-by-step explanation:From the issue, we may deduce that:
x + y = 50 She desires to produce 50 ounces of the combination (because to this).
(0.35x) + (0.60y) = 0.55(x+y) (because we're calculating the amount of salt in each solution and the combination contains 55% salt)
We may take the first equation and replace it in the second equation:
(0.35x) + (0.60y) = 0.55(50) (50)
0.35x + 0.60y = 27.5 when x is substituted.
A system of two equations with two variables is now available:
x + y = 50\s0.35x + 0.60y = 27.5
To determine one of the variables in terms of the other, we may utilize the first equation. Let's figure out y:
y = 50 - x
We now change y in the second equation to the following expression:
0.35x + 0.60(50-x) = 27.5
Finding the value of x:
0.35x + 30 - 0.6x = 27.5
0.25x= -2.5
x= -10
Since the number of ounces cannot be negative, the answer is illogical. As a result, you should double-check your calculations or determine if the issue statement contains a mistake.
To get the answer, you can also try an alternative approach like substitution or elimination. Then, double-check your calculations.

Correct option is A, f(x) -2 has changed the parent function f(x) = (0.5)x to its new appearance.
What modification has caused the parent function to change?The parent function f(x) = log5x has been modified by reflecting it over the x-axis, extending it vertically by a factor of three, and moving it down by three units.
In the picture below you can see the blue line is the graph of the function
f(x) = log(5x) and the green line is the graph of the function
g(x) = log[5(x + 4)] - 2
Since the function f passes at point (2, 1), we must reduce it by 2 units to ensure that it also passes at position (-2, -1). To do this, we add 2 to the function f.
We only need to add 4 to the variable x to have the function go left when we obtain log(5x) - 2.
The function shifts to the left when you add a number to x;
The function moves to the right when you remove a number from x;
The function increases when you add a number to it;
The function decreases when you take a number away from it.
Then we get a function g(x) = log[5 (x + 4)] - 2.

How do you find the sine of an angle in a right triangle?.
To find the sine of an angle in a right triangle, we can use the following relationship:
[tex]sin(angle) = opposite side / hypotenuse\\[/tex]
What is right triangle?
A right triangle is a type of triangle that has one angle that measures exactly 90 degrees (also known as a right angle). This angle is formed by the intersection of two legs of the triangle, which are not the hypotenuse of the triangle. The side opposite the right angle is called the hypotenuse and it is always the longest side of the triangle.
To find the sine of an angle in a right triangle, you can use the following relationship:
[tex]sin(angle) = opposite side / hypotenuse\\[/tex]
This relationship holds true for any angle in a right triangle, not just the acute angles.
For example, if you have a right triangle with an angle of 30 degrees and the opposite side is 5 units and the hypotenuse is 12 units, you can find the sine of the angle by dividing the opposite side by the hypotenuse:
[tex]sin(30) = 5/12 = 0.4166\\[/tex]
It's also important to note that the sine of an angle is always between -1 and 1, and the sine of an acute angle is always positive.

C + A = 33 (even if all were the higher paying adults, that would only be 33x2.25=74.25 far less than <<786.75)
1.59C + 1.59A = 33(1.59) = 52.47 subtract to eliminate C
(2.25-1.59)A = 786.75 -52.47 = 734.28

What are the slope and y-intercept of the linear function y =- 10x 1?.
The slope and y-intercept of the linear function y = -10x + 1 are -10 and (0,1) respectively.
The given linear function is y = -10x + 1.
The slope of a linear function is the coefficient of the x-term. In this case, the slope is -10.
The y-intercept of a linear function is the point at which the line crosses the y-axis. To find the y-intercept, we can substitute x = 0 into the equation and solve for y.
y = -10(0) + 1
y = 1
So, the y-intercept is (0,1).

What is axis ?
An axis is a straight line around which an object or a geometric shape can rotate or be symmetrical. In a coordinate system, an axis is a line that serves as a reference for the location of points in space.
When a function f(x) is reflected over the x-axis, it changes the sign of the y-coordinate values. By reflecting the graph of f(x) over the x-axis, the new function g(x) will have the same shape as f(x) but with all y-coordinate values inverted.
Additionally, by shifting the function up 3 units, it means that the y-coordinate values of the new function g(x) will be 3 units greater than the y-coordinate values of the original function f(x).
So the transformation can be represented as:
g(x) = f(x-1) + 4

What are the law of exponential and logarithmic function?.
The law of exponential and logarithmic function is that the logarithmic functions are the inverses of the exponential functions.
According to the first law, we can multiply two exponential functions with the same base by adding their respective exponents. According to the second law, the exponents must be subtracted in order to divide two exponential functions with the same base.
According to the third law, we must multiply the exponents in order to raise a power to a new power. According to the fourth and fifth laws, we must raise each factor to the same power in order to raise a product or quotient to that power.
