70dB is represented by 100cars in 60sec. Therefore if the number of cats is reduced by 3/4 in the same amount of time(60s), then the decibel level will reduce by 3/4 also. So 70dB * .25= 17.5dB

Simplify the expression. (3x/y)^-3
AysviL [449]

Answer:

y^3/(27 x^3)

Step-by-step explanation:

Simplify the following:

((3 x)/y)^(-3)

((3 x)/y)^(-3) = (y/(3 x))^3:

(y/(3 x))^3

Multiply each exponent in y/(3 x) by 3:

(y^3)/((3 x)^3)

Multiply each exponent in 3 x by 3:

y^3/(3^3 x^3)

3^3 = 3×3^2:

y^3/(3×3^2 x^3)

3^2 = 9:

y^3/(3×9 x^3)

3×9 = 27:

Answer:  y^3/(27 x^3)

Whats a constant and a variable and a coeffecient ?
OLga [1]
A constant is a number, or a letter that represents a number that
never changes.  From the time the problem starts until as long
as it lasts, its value is constant.

A variable is a letter that stands for a number that can change.

A coefficient is each of the items in a group of them that are all
multiplied together.

Example:  17x + 4y

That's an expression with two terms.
The terms are  '17x'  and  '4yz'.

In the first term:
'17' is the numerical coefficient.
'x' is the literal coefficient.

In the second term:
'4' is the numerical coefficient.
'y' and 'z' are both literal coefficients.
