4. JKLM is a parallelogram. Find JM.
J
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

0.069%
6.9%
Answer:
7.4 % is percent error
Step-by-step explanation:
https://brainly.com/question/21689164
The percent of error is 7.4%. The correct option is B.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Estimated value: 231
Actual value: 215
To find the percentage:
First, the value,
= 231 - 215
= 16
Now,
let n be the percentage.
So,
16 = n x 215/100
n = 1600/215
n = 7.4%
Therefore, 7.4% is the error.

When Martin graduates college, he is gifted $1,200 and puts the money into a savings account that earns 2.2% annual interest. How much money will Martin have in 2 years? How much money will Martin have in 5 years?
Answer:
2 years = 1252.80 5 years =1332
Step-by-step explanation:
1,200 x 2.2% = 26.4
26.40 x 2 = 52.80
1200 + 52.80 = 1252.80
26.40 x 5 =132
1200 + 132 =1332
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
A study showed that the ratio of the number of people who get their news from print sources to the number of people who get their news from social media sources is 3:7. Based on the ratio, how many people in a town of 900 people get their news from social media sources?
Two classmates solved this problem and their work is shown below. Which classmate solved the problem correctly? Explain the error in the classmate who solved it incorrectly.
Answer:
270 = number who get news from print sources
630 = number who get news from social media
Step-by-step explanation:
Let 3x = number who get news from print sources
and 7x = number who get news from social media
Then 3x + 7x = 900
10x = 900
x = 90
3x = 3(90) = 270 = number who get news from print sources
7x = 7(90) = 630 = number who get news from social media
Check: 270/630 = 3/7 and 270 + 630 = 900
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

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

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
