Find the m <3 if m<5=130 and m<4 =70

RSB [31]

Answer: 60°

<u>Step-by-step explanation:</u>

∠5 and ∠2 form a Linear Pair so their angles are supplementary.

∠5 + ∠2 = 180

130 + ∠2 = 180

∠2 = 50

∠2 + ∠3 + ∠4 = 180 <em>Triangle Sum Theorem</em>

50 + ∠3 + 70 = 180

∠3 + 120 = 180

∠3 = 60

Use the formula L= 10 log 10 R, where Is the loudness of a sound and R is the sound's relative intensity. to find out how much l

WINSTONCH [101]

Answer:

$X=24.1decibels$

Step-by-step explanation:

From the question we are told that:

Loudness function $L= 10 log_{10} R$

Sound of a person $S_p=80\ decibels\ or 10^8$

Number of persons talking $n=20 people$

Generally the Relative intensity for 20 people is mathematically given by

Relative intensity for $R_{20}=$ $20*10^8$

Relative intensity for $R_{20}=$ $20^8$

Generally the loudness for 20 people is mathematically given by

$L_{20}= 10 log_{10} R$

$L_{20}= 10 log_{10} 20^8$

$L_{20}= 10 (8 log_{10} 20)$

$L_{20}= 104.1 decibels$

Therefore increase in loudness X is given as

$X=104.1-80=-52.90$

$X=24.1decibels$

If x and y satisfy both 9x+2y=8 and 7x+2y=4, then y=?

Alex

Answer:

The value of y is -5

Step-by-step explanation:

we have

$9x+2y=8$ ------> equation A

$7x+2y=4$ ------> equation B

we know that

If x and y satisfy both equations, then (x,y) is the solution of the system of equations

Using a graphing tool

Remember that

The solution of the systems of equations is the intersection point both graphs

The intersection point is (2,-5)

therefore

The solution of the system of equations is the point (2,-5)

The value of y is -5

Apex Learning Study 4.2.1 What units do you use to report the area of a circle with a radius of 50 feet?

klasskru [66]

Answer:

<h3> in square feet</h3>

Step-by-step explanation:

Area of anything is<u> allways </u>reported <u>in square units</u>. Usually that is square of given unit because it's the simplest way:

R = 50 ft

A = πR² = π•(50 ft)² = π • 50 ft • 50 ft = 2500π ft² ≈ 7854 ft²

{Of course you can re-calculate the units, ex.:

3 feet = 1 yard so 50 ft = 50/3 yd then

A = πR² = π•(50/3 yd)² = π • 50/3 yd • 50/3 yd = 2500/9 π yd² ≈ 872.7 yd² }
