Answer:
470 balls
Step-by-step explanation:
Let the number of tennis balls Kerns have be x and the number of tennis balls Hardy has be 3x. We want to find their difference: 3x-x = 2x
Total no. of balls = Kerns + Hardy
= x + 3x
= 4x
4x = 940
2x =
× 940
= 470
Experimentally we got a five 9 times out of 50
Answer: 9/50

Answer:
1)
Ratio is 1:1.
2)
The required number is:
![5^4\times 50](https://tex.z-dn.net/?f=5%5E4%5Ctimes%2050)
Step-by-step explanation:
1)
Let us consider that Cecilia's has a total of 'x' CDs
and let 'y' represent the number of Jazz CDs.
Now we are given information that:
1/5 of her Jazz CDs represents 1/10 of all her CDs.
i.e. ![\dfrac{1}{5}y=\dfrac{1}{10}x\\\\y=\dfrac{5}{10}x\\\\y=\dfrac{1}{2}x](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B5%7Dy%3D%5Cdfrac%7B1%7D%7B10%7Dx%5C%5C%5C%5Cy%3D%5Cdfrac%7B5%7D%7B10%7Dx%5C%5C%5C%5Cy%3D%5Cdfrac%7B1%7D%7B2%7Dx)
i.e. the Jazz CDs are half of the total CDs.
Hence, the number of Non-Jazz CDs(z)
= ![x-\dfrac{x}{2}\\\\=\dfrac{x}{2}](https://tex.z-dn.net/?f=x-%5Cdfrac%7Bx%7D%7B2%7D%5C%5C%5C%5C%3D%5Cdfrac%7Bx%7D%7B2%7D)
Hence, the ratio of Jazz to Non-Jazz CDs
![=\dfrac{y}{z}\\\\=\dfrac{\dfrac{x}{2}}{\dfrac{x}{2}}\\\\=\dfrac{1}{1}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7By%7D%7Bz%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%5Cdfrac%7Bx%7D%7B2%7D%7D%7B%5Cdfrac%7Bx%7D%7B2%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B1%7D)
Hence, the required Ratio is 1:1.
2)
How would you change
to a number times 25?
We will find the number by dividing the quantity
by 25 to find the required number.
i.e. ![\dfrac{5^6\times 50}{25}=\dfrac{5^6\times 50}{5^2}=5^{6-2}\times 50=5^4\times 50](https://tex.z-dn.net/?f=%5Cdfrac%7B5%5E6%5Ctimes%2050%7D%7B25%7D%3D%5Cdfrac%7B5%5E6%5Ctimes%2050%7D%7B5%5E2%7D%3D5%5E%7B6-2%7D%5Ctimes%2050%3D5%5E4%5Ctimes%2050)
Hence the required number is:
![5^4\times 50](https://tex.z-dn.net/?f=5%5E4%5Ctimes%2050)
