Answer:1111

Step-by-step explanation:1111

Using the number line below, where RS=6y+3, ST=4y+8, and RT=61, the value of y was found to be 4.

An area of a line that can connect two points is known as a line segment. A and B, the ends of this line segment, both have fixed lengths. The separation between endpoints A and B is the length of this line segment. An area or portion of a line with two endpoints is known as a line segment. A line segment has a set length as opposed to a line. Both metric measurements, such as millimeters and centimeters, as well as conventional units, such as feet or inches, can be used to measure the length of a line segment. The length of one line segment in comparison to the other when there are two can be determined just by glancing at them. The line segment CD is longer than AB, as can be seen.

given

ST = 2y + 9 RS = 7y + 3

RT = 14y - 8

S lies between R and T, hence we can deduce that:

RS plus ST = RT

Therefore, we can swap out the equations for each of the segments above to obtain:

We can now solve this for y; to do so, let's move all the phrases that begin with y to the left.

14y -7y - 2y = 3 + 9 + 8\s(14 - 7 - 2) (14 - 7 - 2)

*y = 20

5*y = 20

y = 20/5 = 4\

y = 4

The value of y was determined to be 4.

Step-by-step explanation:

The measure of angle L is 66 degrees, which is found using the sum of the internal angle of a triangle. The length is 3.56 units.

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

Given that the measure of angle M is 24 degrees and angle K is 90 degrees.

The sum of internal angles of a triangle is 180 degrees, thus:

[tex]\angle M + \angle K + \angle L = 180\\\\24 + 90 + \angle L = 180 \\\\\angle L = 66[/tex]

The length of side LK can be found as follows:

tan 24 = LK / MK

tan 24 = LK / 8

0.44 * 8 = LK

LK = 3.56 units.

The length of LM can be found by applying the Pythagorean theorem.

Answer:

3.64 meters

Step-by-step explanation:

To find the height of the tree to the nearest hundredth of a meter, you can use the principle of similar triangles.

First, we can use the Pythagorean theorem to find the length of the hypotenuse of the right triangle formed by the height of the tree, the distance between the base of the tree and the point where the shadows meet, and the length of the shadow of the tree.

c = √(a² + b²)

c = √(h² + 26.2²)

Next, we can use the similar triangles to establish a ratio between the length of the shadow and the height of the tree and the length of the shadow and the distance from the tree.

shadow tree / height tree = shadow person / height person

31.55 / h = 31.55 / 26.2

Now, we can cross-multiply and divide to solve for h

h = 31.55 * 1.35 / 26.2

h = 3.64 meters

We can round it up to the nearest hundredth of a meter:

h = 3.64 meters

Therefore, the height of the tree is 3.64 meters to the nearest hundredth of a meter.

This problem can be solved using a system of equations.

What is the system of equations?

A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and graphical solutions are possible for these equations. The point of intersection of two lines represents the system of equations' solution.

Line 1

Taking two points on this line (0,300) and (4,450)

Equation of line y = mx+c

m = [tex]\frac{450 - 300}{4 - 0}[/tex] = 37.5

y = 37.5x + c

Substituting (0,300) in the above equation

300 = 37.5 * 0 + c

c = 300

Line equation y = 37.5x + 300

Line 2

Taking two points on this line (0,400) and (5,500)

m = [tex]\frac{500 - 400}{5 - 0}[/tex] = 20

y = 20x + c

Substituting (0,400) in the above equation

400 = 250* 0 + c

c = 400

Line equation y = 20x + 400

a) The solution of the system is when both lines coincide

     37.5 x + 300 = 20x + 400

     17.5 x = 100

           x = 5.7

            y = 20 * 5.7 + 400 = 514

Therefore the solution of the system is ( 5.7 , 514)

The range (ice to steam) of a Celsius thermometer = 100 C.

The range of the given thermometer = 10 + 110 = 120 degrees.

So, 1 degree C ≡ 1.2 degrees on the given thermometer.

A. So, 20 degrees C ≡ 24 on given thermometer and the reading will be 24 - 10 = 14.

The function is constant in the interval (-6 to 0).

The correct option is (C).

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

If the value of one of the variables does not alter the value of the other, the function is said to be constant.

As we can see, the function is constant in the range from x=-6 to 0, because the value of y in the function does not change as the value of x changes (-6 to 0).

The domain and range of the given graph function is R.

The equation -3x^2 + 12y^2 = 84 represents an ellipse in the coordinate plane. The standard form of an ellipse is (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axis, respectively.

To put the given equation in standard form, we need to divide both sides by 84, and divide the x^2 and y^2 by the square of their respective coefficient:

(-3/84)x^2 + (12/84)y^2 = 1

This gives us x^2/ (84/-3)^2 + y^2/ (84/12)^2 = 1

Which gives us x^2/28 + y^2/7 = 1

This means that the semi-major axis has a length of 2sqrt(7) and the semi-minor axis has a length of sqrt(7).

The domain of this function is all real numbers, because the x values can take any real value.

The range of this function is also all real numbers, because the y values can take any real value, within the boundaries of the ellipse.

The truth of z scores that fall below the mean is - they are negative. Option(b) is the correct answer.

A z-score called a standard score gives an idea of how far from the mean a data point is. But technically it is a calculation of how many standard deviations below or above the population mean a raw score is.

A z-score can place on a normal distribution curve. Z-score ranges from -3 standard deviations up to +3 standard deviations.

A z-score is equal to 0 means that it is on the mean. A positive z-score shows the score is higher than the mean average.

Answer: 49 Stamps

Step-by-step explanation:

If Lauren gave Kristen and Ethan 12 stamps and 15 stamps respectively, that means that she gave them a total of 27 stamps. This leaves her with 22 stamps left. In order to find the number of stamps she had at the start, add the stamps she gave away to the stamps she had left at the end. So,

15 stamps + 12 stamps + 22 stamps = 49 stamps total at the start

Lauren had 49 stamps in the beginning. Since she gives Kristen 12 stamps, and Ethan 15 stamps, we can add both amounts to assume the total number of stamps she gave away. 15+12=27, so she gave away 27 stamps.  Lauren was left with 22 stamps. We can add 22 to 27 to find out how many stamps she had in all. 27+22=49. Therefore, we can come to the conclusion that Lauren had 49 stamps at the start.
