Answer:
$ 4.9 less if you pay the annual subscription
Step-by-step explanation:
What we should do is calculate each of the options and then compare
option A:
worth $ 86 but with a 15% discount, therefore:
86 * 0.15 = 12.9
We deduct this from the original value:
86 - 12.9 = 73.1
Option A is for $ 73.10
option B:
each month is $ 6.50, so multiply by 12, the number of months of the year:
6.5 * 12 = $ 78
Option B comes out for $ 78
if we subtract both options we are left with:
78 - 73.1 = 4.9
that is, they are $ 4.9 less if you pay the annual subscription
Answer:
The frequency doesn't change. If the wavespeed increases, then the wavelength must also increase ... It's just the distance the wave travels during each complete wiggle.
Step-by-step explanation:
- Sound waves are a type of mechanical wave which requires a material medium for transmission. The transmission of such waves occurs as a result of vibration of particles in the material medium. The faster the vibration of the particles the higher the speed of the sound waves.
- When a sound enters a new medium where the sound travels faster, it means the vibration of particles is high, and the wavelength of the waves increases which means the speed of the wave has increased. The frequency on the other hand will remain constant.
Answer:
Step-by-step explanation:
4x+8=.1x+3+3.9x
4x+8=4x+3
No solution since the 4x's will cancel each other out
