Two integers, a and b have different signs. The absolute value of integer that got this description. Then decide if the product
Vika [28.1K]

Since a and b have opposite signs then both the product and quotient will be negative. The absolute value of a · b will be greater than the absolute value of \frac{a}{b}.

Without the absolute value sign, then since both the product and the quotient are negative, a · b < \frac{a}{b}

Answer: the product is less than the quotient

A sound wave is traveling at 6,420m/s and has a frequency of 600Hz. What is the wavelength?
GaryK [48]

Answer:

10.7 m

Step-by-step explanation:

Given that,

The speed of a sound wave, v = 6,420 m/s

The frequency of the wave, f = 600 Hz

We need to find the wavelength of the wave. We can find it using the below relation as follows :

v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m

So, the wavelength of the sound wave is equal to 10.7 m.

algol [13]

Answer:

122 degrees-

Step-by-step explanation:

m\angle {GOC}=m\angle{GOA}+m\angle{AOC}\\=32^\circ + 90^\circ\\=122^\circ

Angle GOA is a vertical angle with angle DOE, so it has the same measure (vertical angles are congruent).

Angle AOC is a right angle because angle COE is a right angle.
