0.2cubed + (1/5 * 3/4) - 1/12

solmaris [256]

Answer:

Step-by-step explanation:

0.2³ + (1/5 × 3/4) - 1/12

According to my syllabus, we use BODMAS. i.e <em>Brackets, Of, Division, Multiplication, Addition </em>and <em>Subtraction</em> in that order.

0.2³ + 3/20 - 1/12

0.008 + 3/20 - 1/ 12

Change the decimal to a fraction and work out the rest.

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

$X=104.1-80=-52.90$

$X=24.1decibels$
