Step-by-step explanation:

Answer:

2

Step-by-step explanation:

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 louder 20 people talking would be than one person talking. Suppose the sound of one person talking has a relative intensity of 80 decibels.

Answers

Answer:

[tex]X=24.1decibels[/tex]

Step-by-step explanation:

From the question we are told that:

Loudness function [tex]L= 10 log_{10} R[/tex]

Sound of a person [tex]S_p=80\ decibels\ or 10^8[/tex]

Number of persons talking [tex]n=20 people[/tex]

 

Generally the Relative intensity for 20 people is mathematically given by

Relative intensity for[tex]R_{20}=[/tex][tex]20*10^8[/tex]

Relative intensity for[tex]R_{20}=[/tex][tex]20^8[/tex]

Generally the loudness for 20 people is mathematically given by

[tex]L_{20}= 10 log_{10} R[/tex]

[tex]L_{20}= 10 log_{10} 20^8[/tex]

[tex]L_{20}= 10 (8 log_{10} 20)[/tex]

[tex]L_{20}= 104.1 decibels[/tex]

Therefore increase in loudness X is given as

[tex]X=104.1-80=-52.90[/tex]

[tex]X=24.1decibels[/tex]

Kevin has $50 and wants to buy some art paper and paints. One pack of art paper cost $12 and the paints cost $6 per tube. He buys 2 packs of paper. Which inequality should Kevin solve to find the maximum number, n of tubes of paint that he can buy

Answers

Answer:

26 ≤ 6

Step-by-step explanation:

$50 is the budget

Art paper = $12

Paints = $6

He gets 2 packs of paper making  it $24

$50 - $24 = $26

26 divided by 6 = 4.33333 (he can only get 4)

The perimeter of a rectangular garden is 68 feet. The length
of the garden is 2 feet more than double the width. What is the
width of the garden?

Answers

Answer:

10 2/3 ft or approximately 10.67 ft

Step-by-step explanation:

Let the width = w

The length is L = 2w + 2.

The perimeter is:

P = 2(L + w)

P = 2(2w + 2 + w)

P = 2(3w + 2)

P = 6w + 4 = 68

6w = 64

w = 64/6

w = 32/3 = 10 2/3

Answer: 10 2/3 ft or approximately 10.67 ft

48 boxes are loaded onto a truck. The still need to load 96% of the boxes onto the truck. What is the total number of boxes being loaded

Answers

Answer:

the total number of boxes being loaded is 1,200 trucks

Step-by-step explanation:

Given that

There are 48 boxes that should be loaded onto a truck

And, still it is required to lead 96% of the boxes onto the truck

We need to find out the total number of boxes that should be loaded

So

Since 48 boxes represent the 4% of the boxes that are loaded

So,

The total number of boxes would be

= 48 × 100 ÷ 0.04

= 1,200 trucks

Hence, the total number of boxes being loaded is 1,200 trucks

comic books
magazines

No links please!
Thank you

Answers

Answer: He bought 1 magazine and 3 comic books.

Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.

Jamal launched a website for his custom shoe store. On the first day, 3 visitors registered on the website. On the third day, 27 visitors registered on the website. If Jamal uses an exponential function to model the data from the first and third days, how many visitors will he predict to register on the fifth day.

Answers

Answer:

Jamal predicts that 243 people will visit his site on the fifth day.

Step-by-step explanation:

Since Jamal launched a website for his custom shoe store, and on the first day, 3 visitors registered on the website, while on the third day, 27 visitors registered on the website, if Jamal uses an exponential function to model the data from the first and third days, to determine how many visitors will predict to register on the fifth day, the following calculation must be performed:

Day 1 = 3

Day 2 = 3 ^ 2 = 9

Day 3 = 3 ^ 3 = 27

Day 4 = 3 ^ 4 = 81

Day 5 = 3 ^ 5 = 243

Therefore, Jamal predicts that 243 people will visit his site on the fifth day.
