What is JL brainliest for answer
Answer:
JL = 12.5
Step-by-step explanation:
[tex] In\: \triangle JKL, KM\perp JL[/tex]
Therefore, by geometric mean property:
[tex] KM^2 = JM\times ML[/tex]
[tex] 6^2 = 8\times ML[/tex]
[tex] 36 = 8\times ML[/tex]
[tex] \frac{36}{8} = ML[/tex]

Laura's new car cost her $21,000. She was told that this make and model depreciates
exponentially at a rate of 8 5/8% per year. How much will her car be worth after 100
months?
Answer: 9,903.32
Step-by-step explanation: 1. y= 21000(1-0.08625)^x
2. y=21,000(1-0.08625) 100/12 = 9,903.32 replace x with 100/12
The value of Laura's car will be $9,903.32 after 100 months.
What is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
The concepts of counting are permutation and combination, and they are used in a variety of contexts. A permutation is a list of the various configurations that can be created from the given set of items. Details are crucial in permutation because the order or sequence is crucial. The order in which the names of the three countries are written matters, whether they are written as "USA, Brazil, Australia" or "Australia, USA, Brazil" or "Brazil, Australia, USA." When combined, the names of three nations form a single unit, regardless of their chronological order.
1. y= 21000(1-0.08625)^x

The distance between Boomtown and Dayville on a map is 13.0 cm. The scale of the map is 10 cm = 25 km
Approximately how far apart are Boomtown and Dayville?
Answer:
32.5
Step-by-step explanation:
We can set this problem up as a proportion:
[tex]\frac{10}{25} = \frac{13}{x}[/tex] In doing this, we find the exact distance from Boomtown to Dayville. Another way to do it is by dividing 25 by 10, to get 2.5, then multiplying 2.5 by 13 to get 32.5
Find the value of x. Then find the measure of each labeled angle.
Answer:
x = 111
Step-by-step explanation:
x + x - 42 = 180 {Lines are parallel. So, they are supplementary}
2x - 42 = 180
Add 42 to both sides
2x - 42 + 42 = 180 + 42
2x = 222 {Divide both sides by 2}
x = 222/2
x = 111

On many cell phones with GPS, an approximate location can be given before the GPS signal is received. This is done by a process called triangulation, which works by using the distance from two known points. Suppose there are two cell phone towers within range of you, located 3000 feet apart along a straight highway that runs east to west, and you know you are north of the highway. Based on the signal delay, it can be determined you are 2050 feet from the first tower, and 1420 feet from the second. Determine the angle, \thetaθ, between your line of sight to the first tower and the highway to the nearest tenth of a degree. (A calculator is needed for this question)
========================================================
Explanation:
Refer to the diagram below.
If we focus on triangle ACD, then we can use the pythagorean theorem to say
d^2 + m^2 = 2050^2
d^2 = 2050^2 - m^2
Now if we focus on triangle DCB, we can also use the pythagorean theorem to say
d^2 + n^2 = 1420^2
2050^2 - m^2 + n^2 = 1420^2 ...... replace d^2 with 2050^2 - m^2
n^2 - m^2 = 1420^2 - 2050^2
n^2 - m^2 = -2,186,100
--------------------------
In the diagram, I set up m and n such that m+n = 3000. This solves to n = 3000-m
We can then say
n^2 - m^2 = -2,186,100
(3000-m)^2 - m^2 = -2,186,100
m^2 - 6000m + 9,000,000 - m^2 = -2,186,100
-6000m + 9,000,000 = -2,186,100
-6000m = -2,186,100 - 9,000,000
-6000m = -11,186,100
m = (-11,186,100)/(-6000)
m = 1864.35
--------------------------
We now have enough to find angle theta, which is the angle between segments AC and AD (the line of sight to the first tower and the highway lines respectively)
We'll focus entirely on triangle ACD
cos(angle) = adjacent/hypotenuse
cos(A) = AD/AC
cos(theta) = m/2050
cos(theta) = 1864.35/2050
cos(theta) = 0.90943902439024 which is approximate
theta = arccos(0.90943902439024)
theta = 24.572056388088
theta = 24.6 degrees
Make sure your calculator is in degree mode. One way to check is that cos(60) should evaluate to 0.5

Using the picture above, find the value ofr. Round to the nearest tenth plssssi need helpppppp
Answer:
11.4
Step-by-step explanation:
Since this triangle is a right triangle, we can solve using SOHCAHTOA.
Our angle is 25 degrees and the given hypotenuse length is 27. So, the best trigonometry equation to use would be sine, since it includes the hypotenuse and the opposite side, which is the r length that we are looking for.
Through SOHCAHTOA, sin 25° = [tex]\frac{opp}{hyp}[/tex]
sin 25° = [tex]\frac{r}{27}[/tex]
r = 27 (sin 25°)
Using a calculator, 27 (sin 25°) ≈ 11.4

The sides of a right triangle form an arithmetic sequence with the difference d. Find the area of an inscribed circle in terms of d.
Answer:
The sides of a right triangle form an arithmetic sequence with the difference is described below in detail.
Step-by-step explanation:
Let's denominate the first term aa and the obvious difference dd. Therefore, your course enhances:
a, a+d, a+2da, a+d, a+2d
Now, these three terms form the sides of a right triangle. Since a+2da+2d is the highest (considering d > 0), we can state that it is the hypothenuse.
applying the Pythagorean Theorem:
a2+(a+d)2=(a+2d)2a2+(a+d)2=(a+2d)2
a2+a2+2ad+d2=a2+4ad+4d2a2+a2+2ad+d2=a2+4ad+4d2
3d2−a2+2ad=03d2−a2+2ad=0
(3d−a)(d+a)=0(3d−a)(d+a)=0
Therefore, your solutions are
3d=a3d=a
andd=−ad=−a
So if a = 3, d = 1. Therfore, one potential sequence is 3, 4, 5.
Similarly, if a = 6, then d = 2, so another potential sequence is 6, 8, and 10
A STADIUM HAS 15,600 SEATS. IT HAS 60 ROWS OF SEATS ALTOGETHER. THE 35 ROWS AT THE BACK HAVE 300 SEATS EACH. THE REST OF THE ROWS AT THE FRONT HAVE THE SAME NUMBER OF EACH SEATS EACH. HOW MANY SEATS ARE THERE IN EACH OF THE ROWS AT THE FRONT
Answer: The number of seats in each of the rows at the front =204
Step-by-step explanation:
Let x = The number of seats in each of the rows at the front.
Given: Total seats = 15,600
Total rows = 60
Rows in back = 35
Rows in front = 60-35=25
Total seats in front = 25x
Each row in the back has 300 seats.
Total seats in the back =300 x35=10500
Seats in front = 15600-10500=5100
i.e. [tex]25x=5100\Rightarrow x=\dfrac{5100}{25}=204[/tex]
Hence, the number of seats in each of the rows at the front =204

x= ?, x=?
Answer:
x = - 5, x = 2
Step-by-step explanation:
Given
x(x + 7) = 4x + 10 ← distribute left side
x² + 7x = 4x + 10 ( subtract 4x + 10 from both sides )
x² + 3x - 10 = 0 ← in standard form
(x + 5)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 2 = 0 ⇒ x = 2
4. JKLM is a parallelogram. Find JM.

к
8x + 4
4x + 20
M
L
Answer:
36
Step-by-step explanation:
8x + 4 = 4x + 20
8x - 4x = 20 - 4
4x = 16 divide both sides by 4
x = 4 and JM = 8x + 4 replace x with 4
8×4 + 4 = 36
Answer:
36
Step-by-step explanation:
8x + 4 = 4x + 20 ( being opposite sides of parallelogram)
8x - 4x = 20 - 4
4x = 16
x = 16 / 4
x = 4
JM = 8x + 4
=8 * 4 + 4
= 32 + 4
= 36

Circumference = ?[tex] \\ [/tex]
[tex] \Large \underline{\tt Solution} :[/tex]
As, we have diameter of circle is 5.6 cm and radius is half of diameter.
[tex] \tt : \implies Radius, r = \dfrac{d}{2}[/tex]
[tex] \tt : \implies Radius, r = \dfrac{5.6 \: cm}{2}[/tex]
[tex] \tt : \implies Radius, r = \dfrac{\cancel{56} \: cm}{10\times \cancel{2}}[/tex]
[tex] \tt : \implies Radius, r = \dfrac{28 \: cm}{10}[/tex]
[tex] \tt : \implies Radius, r = 2.8 \: cm[/tex]
[tex] \\ [/tex]
Now, for Circumference :
[tex] \Large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]
[tex] \tt : \implies Circumference = 2 \times \dfrac{22}{7} \times 2.8 \: cm[/tex]
[tex] \tt : \implies Circumference = \dfrac{44}{\cancel{7}} \times \dfrac{\cancel{28}}{10} \: cm[/tex]
[tex] \tt : \implies Circumference = 44 \times \dfrac{4}{10} \: cm[/tex]
[tex] \tt : \implies Circumference = \dfrac{176}{10}\: cm[/tex]
[tex] \tt : \implies Circumference = 17.6\: cm[/tex]
[tex] \\ [/tex]
Hence, circumference is 17.6 cm.
Are the triangles similar? If so state the similarity and the postulate or theorem that justifies your answer.

Let's find out:
DE/AB = 10/5 = 2

FD/CA = 12/6 = 2
The ratio of their corresponding side lengths are equal, therefore, ∆ABC is similar to ∆DEF based on the SSS Similarity Theorem.
