Using an intensity of 1 × 10-12 w/m2 as a reference, the threshold of hearing for an average young person is 0 db. person 1 and person 2, who are not average, have thresholds of hearing that are β1 = -15.0 db and β2 = +25.0 db. what is the ratio i1/i2 of the sound intensity i1 when person 1 hears the sound at his own threshold of hearing compared to the sound intensity i2 when person 2 hears the sound at his own threshold of hearing?

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
