Answer:
Number of sweets =54
Step-by-step explanation:
Let number of friends = x
Number of sweets = y
Glenda gives 6 to each of her friend,
6x = y ----------------(I)
If she gives each of them 4, 18 is left
4x + 18 = y ---------------(II)
From (I)& (II)
6x = 4x + 18
Subtract 4x from both sides
6x - 4x = 4x + 18 - 4x
2x = 18
Divide both sides by 2
2x/2 = 18/2
x = 9
y = 6x
= 6 * 9
y = 54
Number of sweets =54
Answer:
gain = 0
% = 0
Step-by-step explanation:
<em><u>Profit</u></em>
He sells one for a profit of 25% That means he sells one of them for 100% + 25% = 125%
₹1500 * 125/100 = ₹187500/100 = ₹1875
<em><u>Loss</u></em>
Here he sells it for 25% less than the selling price he wanted.
100% - 25% = 75%
₹1500 * 75/100 = ₹112500/100 = ₹1125
<em><u>Discussion</u></em>
He should make ₹1500 + ₹1500 = ₹3000 without either profit or loss.
What he actually accomplishes is ₹1125 + ₹1875 = ₹3000
So he has a net gain (loss) of 0.
The % is 0

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.
