Roman55 [17]

Answer:

number of yellow marbles=62.

Step-by-step explanation:

It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.

Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.

Now, Total number of marbles= number of yellow marbles+number of blue marbles.

⇒73=x+5x+7

⇒73-7=6x

(PLEASE ANSWER: TIMED)The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation I(dB)=1
Mrac [35]
For this case we have the following equation:
 l(dB) = 10log( \frac{l}{lo} )
 We must replace the following value in the equation:
 l = 10^8lo
 Substituting we have:
 l(dB) = 10log( \frac{10^8lo}{lo} )
 Simplifying the given expression we have:
 l(dB) = 10log(10^8)
 Then, using logarithm properties in base 10, we can rewrite the expression:
 l(dB) = 10(8)
 Finally, making the product, the result is:
 l(dB) = 80
 Answer:
 
l(dB) = 80
