Rational numbers are numbers that can be written as a ratio. That means that it can be written as a fraction. All whole numbers are rational.

Irrational numbers can be written as a decimal but not as a fraction.

sammy [17]

The distance between is =|9|+|-6|=15.
We can find that
$\frac{2}{5} \times 15 = 6$
So 2/5 of the AB segment is 6 distance points away from A at point C=0.

A water color is 20 inches long by 9 inches wide. Ramon makes a boreder around the watercolor painting by making a mat that adds

neonofarm [45]

The area of the mat = total area added minus the original area of the water color painting.
length of the mat is:L = 20 in + 1 in + 1 in because 1 in is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in
Area mat = (22 in x 11 in) - ( 20 in x 9 in)
area mat = 62 sq in is the area of the mat

What is the decibel level of the sound of a monster truck with intensity 10−2 watts per square inch? Use a logarithmic model to

lorasvet [3.4K]

Answer:

BdB = 68.10 decibels

Step-by-step explanation:

BdB = 10 log10 I / Io

where BdB is the sound intensity level in decibels, I is the sound intensity on the linear scale (W / m²) and I0 is the hearing threshold (10^-12 W / m²).

Converting Io de 10^-12 W/m² to W/in², tenemos

10^-12 W/m² = 1.5500031000062x10^-9 W/in²

So, applying the equation or formula,

BdB = 10 log10 (10 ^ -2 W/in² / 1.5500031000062x10^-9 W/in² )

BdB = 10 log10 (0.64516x10^6)

BdB = 10 log10 (6,451,600)

Being log10 (6,451,600) = 6.8096674332398761189214526331036, then

BdB = 10 x 6.8096674332398761189214526331036

BdB = 68.096674332398761189214526331036

BdB = 68.10 decibels
