The length of the RS is 25 units, using SAS Congruence.

What is SAS Congruence?

Congruent refers to figures that are equal in all respects, particularly in terms of size and shape. Congruence is a mathematical concept that describes the relationship between two congruent figures. The relationship between two congruent figures is referred to as congruence. Let's now talk about the triangle SAS congruence. The phrase SAS congruence often referred to as Side Angle Side congruence, is used to define the relationship between two congruent figures. To fully grasp the significance of SAS, let's talk in-depth about the triangle SAS congruence.

We have specified that TQ is 18 units in length.

TQ = RT as a result,

and 2x + 10 = 18

2x = 18 - 10

2x = 8x2 = 4 units.

Now that both triangles satisfy the Right Angled Hypotenuse Side criteria or SAS concurrency criteria,

RS = QS.

= 9x - 11

= 9(4) - 11

= 25 units.

Hence, the length of the RS is 25 units, using SAS Congruence.

The hourly pay before the increase for marta and khalid is 21 and 17.5.

Given:

the ratio of martas hourly pay to khalids hourly pay is 6:5 both marta and Khalid get an increase of 1.50 in their hourly pay The ratio of Martas hourly pay to Khalid hourly pay after this increase is 13:11

Let x and y be the hourly pay before increase

x/y = 6/5

x = 6/5*y

x + 1.50 / y + 1.50 = 13/11

In mathematics, word problem refers to a question including mathematical information written in ordinary language and requires students to apply their math knowledge to a real-life scenario. For the given case,

Let M be the number of multiple choice questions and N be the number of short answers.

As multiple-choice questions are worth 2 points each and the short answers are worth 6 points each and there is a total of 100 points:

2M + 6N = 100

The total number of questions on the test are 36:

M + N = 36

M = 36 – N

Substituting this into the first equation:

2(36 – N) + 6N = 100

72 – 2N + 6N = 100

4N = 100 – 72

4N = 28

Relative humidity:

                             Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 % relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain — it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.

The linear system of equation y = x+2 and 6x = 4y+10 has only one solution.

The linear equation is y = x+2 and 6x = 4y+10

Now we solve the equations by substitution:

Using the value of y from the first equation and substituting in the second equation we get:

6x = 4y + 10

6x = 4(x+2)+10

or, 6x-4x = 8 + 10

or, 2x = 18

at x=9 , y =11

Hence solution is (9,11) which represents the point of intersection of the two lines.

The geometric series was significant in the early development of calculus, is utilized throughout mathematics, and can serve as an introduction to commonly used mathematical tools such as the Taylor series, complex Fourier series, and matrix exponential.

The name geometric series implies that each phrase is the geometric mean of its two nearby terms, in the same way that the word arithmetic series implies that each term.

Given the geometric series 1+1/3+1/9+1/27+...we must verify the value of its common ratio to determine whether the geometric series is convergent or divergent. The value of a geometric series common ratio is used to determine whether it is convergent or divergent.

If |r| <1, the series is convergent.

If |r| >1, the series is divergent.

The common ratio is r.

The common ratio r = (1/3)/1 = (1/9)/(1/3) = (1/27)/(1/9)=1/3 is derived from the given series.

Because r = 1/3, which is smaller than one, the series is convergent.

Because the geometric series tends to infinity, we will apply the formula for calculating a geometric series sum to infinity to get its sum.

The first term = 1

S = a/1-r

a is the first term = 1

r is the common ratio = 1/3

S = 1/1-(1/3)

Each base angle 72 degrees  is the measure of the vertex angle of an isosceles triangle if the measure of the base angle is 36

For any triangle, the three angles always add to 180 degrees.

In an isosceles triangle, the base angles are the same measure. For now we don't know what they are, so let's call them x. The vertex angle is 36.

Adding the three angles (x, x, and 36) and setting that equal to 180 will help us find the value of x.

x+x+36 = 180

2x+36 = 180

2x+36-36 = 180-36 .... subtract 36 from both sides

2x = 144

2x/2 = 144/2 .... divide both sides by 2

x = 72

If confidence level is 99%, is the result more reliable than confidence level 95%?

If c level is 99%, more error would be included in null hypothesis area, than level 95%. if c level is 99%, it means '99% of deviation would be regarded as in the null area anyway.

So actually, c level 99% means it's less precise than 95%, right? Rather, if confidence level is very small like 5%, so the 'c' value goes closer to μ0, it would mean that we will regard more values to be error. So it must be more precise.
