Answer:
y = 0
Step-by-step explanation:
Let's use the addition method.
2x + y - 10 = 0
x - y - 5 = 0
Write the first equation as is. Write below it the second equation multiplied by -2 on both sides. Then add the equations.
2x + y - 10 = 0
(+) -2x + 2y + 10 = 0
--------------------------------
3y = 0
Divide both sides by 3.
y = 0
Answer: y = 0

Angle C = 95 degreesAngle D = 72 degreesAngle F = 108 degreesArc CFE = 216 degrees================================================
Explanations:
For any inscribed quadrilateral like this, the opposite angles are always supplementary. So that means C+E = 180. Plugging in E = 85 leads to C = 95.Angle D is an inscribed angle that subtends arc CFE. By the inscribed angle theorem, the inscribed angle is half that of the arc it cuts off, so angle D is half of 144 degrees at 144/2 = 72 degrees.Use the idea mentioned in problem 1. So we'll have F+D = 180. Plug in D = 72 to find that F = 108.Arcs CDE and CFE form a full circle. So the arc measures must add to 360 degrees. We simply subtract 144 from 360 to get the answer 216. As an alternative, you can use the idea mentioned in problem 2, but work in reverse.I need help for this math question ASAP
A line segment joins points P(–1, –7) and Q(7, 3). Determine the length of PQ to 1 decimal place.
The loudness L of sound in decibels is given by L=10log(I/I0) where I is the intensity of the sound, and I0 is the intensity of the least audible sound. If I0=10^-12 W/m^2 about how many times more intense is a 97 decibel sound than a 93 decibel sound?
A. 4.5
B. 1.5
C. 2.5
D. 3.5
97 decibel sound is 2.5 times more intense than a 93 decibel sound
Correct option is C.
What is intensity of sound?Sound intensity also known as acoustic intensity, is defined as the power transmitted by a sound wave per unit area in a direction perpendicular to that area. Sound intensity is the sound power in watts divided by the area (in square meters) covered by the sound. Sound loudness relates the intensity of a particular sound to its strength at the threshold of hearing, measured in decibels (dB).
Given expression for loudness
L = 10 log(I/I₀)
Loudness of two different sounds are
L₁ = 97 decibel and L₂ = 93 decibel.
Let the intensity for the loudness L₁ and L₂ are I₁ and I₂
Then,
L₁ = 10log(I₁/I₀) = 97
⇒ log(I₁/I₀) = 9.7
taking antilog
I₁/I₀ = antilog (9.7)
I₁/I₀ = 5011872336.27271
L₂ = 10log(I₂/I₀) = 93
⇒ log(I₂/I₀) = 9.3
taking antilog
I₂/I₀ = antilog (9.3)
I₂/I₀ = 1995262314.96888
Then,
(I₁/I₀)/(I₂/I₀) = 5011872336.27271/1995262314.96888
I₁/I₂ = 2.51188643 ≈ 2.5
Hence, 2.5 times more intense is 97 decibel sound than 93 decibel sound.

Answer:
6) 62.5%
7) 54
8) B
Step-by-step explanation:
For number 6, just add 96 and 160 and then do 160/(96+160), which is equal to 0. 625, or 62.5%.
for number 7, x is always equal to 1/3 of y, so if x is 18, we know that 18 is 1/3 of y. 18x3 is equal to 54, which is your answer.
For number 8, you can see that B is right because it uses the greatest common factor of 32 and 48, which is 16. All the other answers can be simplified more.
Answer:
6. C) 62.5%
7. D) 54
8. B) 16(2c + 3d)
Step-by-step explanation:
160 + 96 = 256
[tex]\frac{160}{256}=\frac{160/32}{256/32}=\frac{5}{8}[/tex]
5 ÷ 8 = 0.625
0.625 × 100
62.5%
GCF = 32
The factors of 160: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
The factors of 256: 1, 2, 4, 8, 16, 32, 64, 128, 256
The GCF is 32.
1:3 = 7:21 = 9:27 = 13:39 = 18:y
[tex]\frac{1}{3}: \frac{18}{y}[/tex]
1 × y = 18 × 3
y = 54
GCF(32, 48)
32 = 2 × 2 × 2 × 2 × 2
48 = 2 × 2 × 2 × 2 × 3
GCF = 2 × 2 × 2 × 2
GCF = 16

Two villages are 14km apart in real life. How far apart would they be on A map scale with 1:25000
Given:
Distance between two villages = 14 km
Map scale = 1:25000
To find:
The distance between the two villages on the map.
Solution:
Let the distance between the two villages on the map be x.
Map scale is 1:25000. So,
[tex]\dfrac{x}{14}=\dfrac{1}{25000}[/tex]
[tex]x=\dfrac{1}{25000}\times 14[/tex]
[tex]x=0.00056[/tex]
Therefore, the two villages are 0.00056 km apart on map.

Answer:
Step-by-step explanation:
∠EMC = ∠EMD + ∠DMC
∠EMC = 90
∠EMD + ∠DMC = 90
∠EMD + 20 =90
∠EMD = 90 - 20
∠EMD = 70
∠FMD + ∠DMB = 180 {Linear pair}
90 + ∠DMB = 180
∠DMB = 180 - 90
∠DMB = 90
need help finding the value of f (7)
Answer:
f(7) = -4
Step-by-step explanation:
f(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3 - x = 3 - 7 = -4
Put in another way:
f(x) = 3 - x
f(7) = 3 - 7
f(7) = -4
Edgar owns 234 shares of Cawh Consolidated Bank, which he bought for $21.38 apiece. Each share pays a yearly dividend of $3.15. Edgar also owns two par value $1,000 bonds from Cawh Consolidated Bank. The bonds had a market value of 105.166 when he bought them, and pay 8.3% interest yearly. Which aspect of Edgar’s investment in Cawh Consolidated Bank offers a greater percent yield, and how much greater is it? a. The stocks have a yield 6.43 percentage points greater than that of the bonds. b. The stocks have a yield 6.84 percentage points greater than that of the bonds. c. The bonds have a yield 1.05 percentage points greater than that of the stocks. d. The bonds have a yield 9.13 percentage points higher than that of the stocks.
Answer: B. The stocks have a yield 6.84 percentage points greater than that of the bonds.
Step-by-step explanation:
Firstly, the yield for stocks will be calculated as:
= return/ investment cost
= $3.15/$ 21.38
= 0.14733395
= 14.73%
The yield for bonds will be calculated as:
= Return/Investment cost
Return = 1,000 x 8.3% = 83
Investment cost = 1,000 x 105.166/100 = 1051.66
Yield = 83/1051.66
= 0.07892284
= 7.89%
Then, the difference between the yield will be:
= 14.73% - 7.89%
= 6.84%
Therefore, the stocks have a yield 6.84 percentage points greater than that of the bonds.
Answer:
b.The stocks have a yield 6.84 percentage points greater than that of the bonds. Step-by-step explanation: got it right on edge 2022!
