Answer:
O weight in kilograms = 25 x 3.5 ÷ 2.2
Step-by-step explanation:
As a butcher, you sell beef in 3.5-pound packages. You anticipate needing 25 packages for the next two days.
Therefore, the total number of pounds for the 25 packages =
3.5 pound packages × 25
= 87.5 pounds
We are told that : The wholesaler from whom you purchase large pieces of meat measures the weight of the beef in kilograms.
Note that:
2.2 pounds = 1 kg
Hence:
87.5 pounds =
= 87.5÷ 2.2
= 39.772727273 kg
He needs to buy 39.772727273kg from the wholesaler
The equation can you use to determine the weight of the beef, in kilograms, that you need to purchase from the wholesaler is:
O weight in kilograms = (25 x 3.5) ÷ 2.2
Answer:
a) Frequency remains constant
b) Wavelength remains constant
c) speed of the wave remains constant
d) Intensity decreases
e) amplitude of its electric field decreases
Explanation:
a) Frequency can be defined as the number of crests that pass a fixed point in the medium in unit time. It is the source of the wave that will determine the frequency. If the small source is changed to a bigger and faster one then the frequency will change. In our case, there is no change of source of wave, so the frequency remains constant.
b) The speed of of the wave is directly proportional to the wavelength. If we double the speed, the wavelength also doubles. Since the speed has not been doubled in our case, the wavelength will remain constant.
c) As indicated in b) since the wavelength is proportional to speed and it has not changed in our case, then the speed remains constant.
d) The intensity of a wave decreases as it moves further away from the source.
e) The intensity is related to the amplitude. Since the intensity decreases, the amplitude also decreases.
%60 because i dont know why actually
