100 + 100 * 10/100 = 110
NOW 110 INCREASES BY 10 %, 110 + 110*10/100 = 110+ 11 = 121
INCREASE OF 20 % = 100 + 100*20/100= 100+20 = 120
SO IT IS NOT SAME
Answer:

Step-by-step explanation:
Let
x-----> the population of the city
we know that
using proportion


solve for "K", to see what "K" is, or the "constant of variation",
once you found K, plug it back in y=Kx, and that's the equation
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.
X/3 +10=15
-10 -10
x/3 =5
so the x will be 15 because if you multiply 3x5 = 15
