After converting all the given units of length into meters we get,

[tex]108 in = 2.7432 m\\108 ft = 32.9184 m\\12 ft = 3.6576m\\1 yd= 0.9144m[/tex]

As per the question statement, we are supposed to convert these given units of length into meters i.e., 108 inches, 108 feet, 12 feet, 1 yard.

We know

[tex]1 foot = 12 inches[/tex]

[tex]1 inch = 2.54 cm\\[/tex]

[tex]12 inches = 2.54*12=30.48 cm\\1 cm = 0.01 m \\30.48 cm = 0.3048 m[/tex]

Therefore, we can infer that 1 foot = 0.3048 m

So,

[tex]108 in = 2.7432 m\\108 ft = 32.9184 m\\12 ft = 3.6576m\\[/tex]

According to the Pythagoras theorem, the square of the hypotenuse is equivalent to the sum of the square of other two sides.

From the given diagram, the expression below is true;

6^2 = 3^2 + (3+x)^2

Determine the value of x

36 = 9 + (9+6x + x^2)

36 = 18 +6x+x^2

x^2 + 6x - 18 = 0

Answer: four less than three times a number is 3x - 4. the number plus ten is x + 10. the same means the two statements are equal to each other.

Step-by-step explanation:

The true statements are: (A), (D), (E) and (F).

Statement A is true. A triangle is said to be isosceles if its two sides are of equal length. Considering the triangle STU, the sides ST and TU are the radius of the same circle centered at T and hence of same length. So triangle STU is isosceles.

Statement B is false. In triangle STU, ST and TU being radii of circle T, are equal. But the third side SU is not a radius of any circle in the diagram and so not equal to ST and TU. Since three sides are not of same length, triangle STU is not an equilateral triangle.

Statement C is false. In Triangle STU two sides are composed of a single radii and not of two radii. The third side is not composed of radii.

Statement D is true. In triangle STU, two sides are radii of circle T but the third side, segment SU, is not a radius of any circle shown in the diagram.

Statement E is true. In triangle VWZ, each side is composed of 2 radii which are of same length. Hence three sides are equal and so it is an equilateral triangle.

Statement F is true. Each side of triangle VWZ is composed of two radii that have the same length.

The formula for calculating the probability of one success under certain conditions is:

x=0.4.

"The ratio of the number of favorable outcomes to the total number of outcomes is the standard mathematical definition of probability. Probability is never more than one, and it is never equal to that number."

Generally, the equation for Probability is  mathematically given as

According to the question,

Total number of trials n'=4

Number of successes r =1

p=0.35

q=1-0.35

q=0.65

Simply replace the value in order to calculate the appropriate probability.

The total proportion of shirts between two prices is 0.9431, which is obtained using the knowledge of proportion and statistics.

What is proportion?

In mathematics, a proportion is defined as the comparison between two numerical quantities. If both possess the same nature, they are called directly proportional, or else called inversely proportional.

Calculation of the proportion based on the problem

The mean and standard deviation are given to be 45 and 5 respectively

Calculate standard normal variate using the formula, z = (x - 45) / 5

Taking x = 37, we get,

z1 = (37 - 45) / 5

= -1.6

Using the z table, we get the value, z1 = 0.0548

Now, taking x = 59.35, we get,

z2 = (59.35 - 45) / 5

= 2.87

Using the z table, we get the value, z2 = 0.9979

The proportion between two prices is given by z = z2 - z1

z = 0.9979 - 0.0548

= 0.9431

Hence, the proportion of shirts between the two prices is 0.9431.

On the number line, It is true to the claim that the solution to the expression 32 + (-17) is 17 units from 32 in the positive direction.

A number line is an illustration of a graded straight line that represents actual numbers. What we call a "number line" is really a horizontal line with regularly spaced number increments. The number line's response format is determined by the numbers it contains.

All possible numbers may be plotted along a line called a number line. Any real number may be represented by a single dot on a number line.

On the number line, we have the negative numbers on the -ve x-axis to the left and they are smaller than the positive numbers to the right, and this is immediately apparent when looking at a number line.

Given that:

= 32 + (-17)

= 32 - 17

= 17

We can therefore conclude that the given expression shows that we are 17 units far away from 32 in the positive x-axis on the number line.

A system of equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.

You can solve a system of equations by the adding or substitution methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.

First, you should convert the text of the question into a math expression. Then,

       5B+3L=92, where B= libretas  and L=lápices.

       2B+6L=56, where B= libretas  and L=lápices.

Therefore,

5B+3L=92 (1)

2B+6L=56  (2)

After that, you should multiply equation(1) by -2. Thus,

-10B-6L=-184(1)

2B+6L=56  (2)

Now, when you sum equations 1 and 2, you  eliminate L . Thus, from this sum, you will have:

-8B=-128

B=128/8

B=16

If B=16, from equation 2, you can find L.

2B+6L=56  (2)

2*16+6L=56

32+6L=56

6L=56-32

6L=24
