Answer:
Speed = 80 m/s
Step-by-step explanation:
The formula to find the speed of a wave is found by
Speed = Wavelength x Frequency where the frequency is in HZ and the wavelength is in meters
Speed = 200 * .40
Speed = 80 m/s
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. In our tomato example, that ratio is $3.00/2, which equals $1.50. Two quantities are directly proportional when they increase and decrease at the same rate.
Step-by-step explanation:
Exterior angles are those on the outside of the triangle, while interior angles are those on the inside of the triangle.
