Answer:
C.
Step-by-step explanation:
as M is right over the middle of LN, this is an isoceles triangle (both legs are equally long).
so, we need to calculate only one leg and then double it fit both legs.
we get e.g. LM via Pythagoras.
LM is the Hypotenuse of the right-angled triangle with half of LN and the height to M being the legs.
so,
LM² = height² + (LN/2)² = 3² + 6² = 9 + 36 = 45
LM = sqrt(45) = 6.708203932... units
the perimeter is the sum of all 3 sides :
LN + LM + MN = LN + 2×LM = 12 + 2×sqrt(45) =
= 25.41640786... units

Right triangle DEF is shown below.What is DF to the nearest tenth of a meter?
Answers
Answer: 25.1º
Explanation
As the given triangle is a right triangle, we can use trigonometric functions to find DF, specifically:
[tex]\cos x=\frac{adjacent}{hypotenuse}[/tex]where the adjacent is the side adjacent to our angle and the hypotenuse is the longest side (side opposite to the 90º angle).
Based on this, we can replace the values as follows:
[tex]\cos(23\degree)=\frac{DF}{27.3}[/tex]Solving for DF:

The option that best describes the elevation of Desert Shores is; A. Desert Shores is lower than 55 meters below sea level.
What is the Elevation below sea level?We are told that the elevation of Desert Shores, California, is less than -55 meters.
Now, an elevation of a natural landmass like this is usually given with reference to the sea level. If above sea level, it is positive but if below sea level, it is negative.
Now, the elevation is negative as we can see that it is given as -55 meters. Thus, we can easily conclude that Desert Shores is lower than 55 meters below sea level.

Representing system of linear equations with a matrixFrom the question, we are to represent the given system of linear equations with a matrix.
The given system of equations is
2x + 3y + 5z = 9
-x + 4z = 10
-6x + z -12 = y
First, we will write the third equation in standard form
-6x + z -12 = y
This becomes
-6x - y + z = 12
Thus,
The system of equations becomes
2x + 3y + 5z = 9
-x + 4z = 10
-6x - y + z = 12
Thus,
The system of equations can be written as a matrix as shown below

Yes they are vertical angles, the angles are nonadjacent and are formed by intersecting lines.
What are Vertical Angles?When two lines that are straight intersect with each other, they form two pairs of opposite angles that are called vertical angles.
Vertical angles share a common vertex both no common sides and are therefore referred to as non-adjacent angles.
Thus, the image shows that lines intersect to form angle 4 and angle 7.
Angle 4 and angle 7 share a common vertex but do not share a common side, hence they are nonadjacent to each other, as shown in the diagram.

Answers
From trigonometric ratios we calculate the value of the cos C is 4/9 and the value of cosec C is 9/√65 .
Real functions known as trigonometric functions in mathematics connect right-angled triangle angles and the ratios of their two side lengths.
The terms trigonometric functions, circular functions, and angle functions are also used to describe them. Trigonometric functions are frequently employed in all fields of study involving geometry, including geodesy, solid mechanics, celestial mechanics, and many more. Given that one of the most fundamental periodic functions is the Fourier transform, it is frequently employed to examine periodic phenomena.Sine, cosine, and tangent are the three trigonometric functions that are employed in modern mathematics the most frequently. The less common cotangent, secant, and cosecant are their reciprocals. The hyperbolic functions and their corresponding inverse functions have analogues for each of these six trigonometric functions.We know that sec C = 1/cos C
Hence the value of cos C = 4/9 .
Again we know that the value of sin C=1/cosec c
Therefore the value of cosec C is 9/√65 .

The slope of the line is indefinite (∞). Also, the line will be parallel to the x-axis.
It is given in the question that a line passes through the points (7, 10) and (7, 20).
We have to find the slope of the line.

Slope of a line with coordinates (a,b) and (c,d) is given by:-
(d - b)/( c - a)
Here,
a = 7,
b = 10,
c = 7 and,
d = 20
Hence, we can write,
Slope of the line = (20 - 10)/( 7 - 7) = 10/0 = ∞.
Hence, the slope of the line is indefinite.

The value of a, b, c and d are 25, 3, 14 and 7 such that the sum of all rows, columns and diagonals are 48.
Given to us a magic square in which the sum of all rows, columns and diagonals are same. Then, we have to complete the missing numbers i.e., a, b, c and d respectively.
Let's proceed to solve this magic square accordingly.
First let's calculate that what will be the sum of all rows, columns and diagonals.
From the figure of magic square one diagonal is completely filled from that we can easily calculate the sum of the diagonals.
Sum = 5+16+27 = 48
Then, we can find the value of a, b, c and d easily.
5+a+18 = 48
23+a = 48
a = 48-23
a = 25
Therefore, the value of a is 25.
29+16+b = 48
45+b = 48
b = 48-45
b = 3
Therefore, the value of b is 3.
Now, 5+29+c = 48
34+b = 48
c = 48-34
c = 14
Therefore, the value of c is 14.
Then, we have
c+d+27 = 48
14+d+27 = 48
41+d = 48
d = 48-41
d = 7
Therefore, the value of d is 7.
Hence, we have completed the magic square in which the sum of all rows, columns and diagonals are 48.
Therefore, the value of a, b, c and d are 25, 3, 14 and 7 respectively.

Answers
Cost of the ad is $167.5
What is cost?
A cost is the worth of money that has been used up to create something or supply a service and is thus no longer accessible for use in production, research, retail, or accounting. In business, the cost might be one of acquisition, in which case the money spent to obtain it is recognized as cost. In this situation, money is the input that is used to purchase the item. This acquisition cost might be the total of the original producer's production expenses and the acquirer's additional transaction costs over and above the amount paid to the producer. Typically, the price includes a profit margin above the cost of manufacture.

strawberries and y pounds of apples?

Answer:
Answer bellow with explanations
Step-by-step explanation:
if Miriam buys 0.5 pounds of strawberries and 3 pounds of apples she will in total would have bought 3.5 pounds of fruit.
if you are looking for the price she had to pay for the fruits above the equation to solve that is as following.
0.5 x 3$ = 1.5$
3.0 x 3.25 = 9.75$
total for the fruits needed above would be 1.5$ + 9.75$ = 11.25$
if you are looking for the amount of pounds converted into the amount of fruit
0.5/3$ = 0.16(6) pounds of strawberries
3/3.25$= 0.92307692307 pounds of apples
total of pounds of fruit that have been purchased is equal to 0.16(6) + 0.92307692307 = 1.08974358973 pounds

22 - 8 = 14.
Now we are at 9 A.M, it is 14 degrees. But, the temperature had doubled from 5-9 A.M, so we would divide our fourteen by two in order to half it.
14 ÷ 2 = 7.
Now we are at 5 A.M.
From midnight to 5 A.M the temperature dropped fourteen degrees so we would add that fourteen back into the equation.
