Answer:
9y = 18 + 7x
y = 2 + 7/9x
Just rearrange and put into that form
A=pie×radius squared is the area formula of a circle. The circumference formula or a circle is C=pie×diameter. 615.75=(3.14)(radius) squared. Divide both sides by the 3.14. What ever 615.75 divided by 3.14 is-is radius squared. The square root is your radius. The radius is half the diameter, so double what you have right now as the radius to get the diameter. Now since C=pie×diameter, your circumference is your pie×your diameter. Whatever your answer is-is your circumference.
Answer:
C. 5 goes into 100 twenty times, and 1 times 20 is 20
Step-by-step explanation:
Since, we know that when we multiply both numerator and denominator of a fraction by a same number then we obtain an equivalent fraction,
Here, the given fraction,
![\frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D)
By the above statement,
![\frac{1}{5}=\frac{1\times 20}{5\times 20}=\frac{20}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B1%5Ctimes%2020%7D%7B5%5Ctimes%2020%7D%3D%5Cfrac%7B20%7D%7B100%7D)
Now,
![a\%=\frac{a}{100}](https://tex.z-dn.net/?f=a%5C%25%3D%5Cfrac%7Ba%7D%7B100%7D)
![\implies \frac{20}{100}=20\%](https://tex.z-dn.net/?f=%5Cimplies%20%5Cfrac%7B20%7D%7B100%7D%3D20%5C%25)
Hence,
![\frac{1}{5}=20\%](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%3D20%5C%25)
Option C is correct.
