Answer: The required ratio is 1:1.
Step-by-step explanation:
Let the total number of CDs be 100
of CDs is given by
![\frac{1}{10}\times 100\\\\=10](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D%5Ctimes%20100%5C%5C%5C%5C%3D10)
According to question,
of her Jazz CDs represents
of all her CDs.
Let the number of Jazz CDs be x
So, it becomes
![\frac{1}{5}\times x=10\\\\x=10\times 5\\\\x=50](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%5Ctimes%20x%3D10%5C%5C%5C%5Cx%3D10%5Ctimes%205%5C%5C%5C%5Cx%3D50)
So, Number of Jazz's CDs is 50
Number of Jazz non CDs is given by
![100-50=50](https://tex.z-dn.net/?f=100-50%3D50)
Ratio of her CDs to her non- CDs is given by
![50:50\\\\1:1](https://tex.z-dn.net/?f=50%3A50%5C%5C%5C%5C1%3A1)
Hence, the required ratio is 1:1.
Answer:
2/3 ( 3x - 4 ) + 3x = 5/6
2x - 8/3 + 3x = 5/6
5x - 8/3 = 5/6
6(5x -8/3) = 6x5/6
30x - 16 = 5
<u> +16 +16</u>
<u>30x = 21</u>
30
x = 21/30
x = 0.7
Step-by-step explanation:
- distribute the bracket by 2/3
- combine like-terms
- multiply both sides by 6 (lcm of 3 and 6)
- add 16 to both sides
- divide both sides by 30 to get x
Answer:(a)
Step-by-step explanation:
Given
Principal amount ![P=\$ 5000](https://tex.z-dn.net/?f=P%3D%5C%24%205000)
Rate of interest ![R=3.5\ \%](https://tex.z-dn.net/?f=R%3D3.5%5C%20%5C%25)
Time ![T=5\ years](https://tex.z-dn.net/?f=T%3D5%5C%20years)
Simple interest in 5 years
![S.I.=\dfrac{P\times R\times T}{100}](https://tex.z-dn.net/?f=S.I.%3D%5Cdfrac%7BP%5Ctimes%20R%5Ctimes%20T%7D%7B100%7D)
![S.I.=\dfrac{5000\times 3.5\times 5}{100}](https://tex.z-dn.net/?f=S.I.%3D%5Cdfrac%7B5000%5Ctimes%203.5%5Ctimes%205%7D%7B100%7D)
![S.I.=875\ \$](https://tex.z-dn.net/?f=S.I.%3D875%5C%20%5C%24)
So total amount after five years![=5000+875=\$ \ 5875](https://tex.z-dn.net/?f=%3D5000%2B875%3D%5C%24%20%5C%205875)
Hi! Can you please be more clear on your question?
Answer:
9676
Step-by-step explanation:
![2 x 21 x 82 + 38 x 82 +2 x \frac{38 x 82}{2} = 9676](https://tex.z-dn.net/?f=2%20x%2021%20x%2082%20%2B%2038%20x%2082%20%2B2%20x%20%5Cfrac%7B38%20x%2082%7D%7B2%7D%20%3D%209676)
