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
.
Without the absolute value sign, then since both the product and the quotient are negative, a · b <
Answer: the product is less than the quotient
Answer:
They are congruent, they are right angles
Step-by-step explanation:
Just in general, all vertical angles are congruent.
But in this situation, perpendicular lines will always create right angles.
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 :

So, the wavelength of the sound wave is equal to 10.7 m.
Answer:
122 degrees-
Step-by-step explanation:

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.
