Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
Let us call the three coins
, and
.
The first coin
is 5 times another coin<em> (let's say </em>
); therefore,
,
and the third coin is 2 times the value of another coin<em> (it's coin </em>
<em>):</em>
<em />
<em>.</em>
The total worth of all coins is 404; therefore,
![a+b+c =404](https://tex.z-dn.net/?f=a%2Bb%2Bc%20%3D404)
or
![5b+b+2b =404](https://tex.z-dn.net/?f=5b%2Bb%2B2b%20%3D404)
![8b =404](https://tex.z-dn.net/?f=8b%20%3D404)
![\boxed{b = 50.5}](https://tex.z-dn.net/?f=%5Cboxed%7Bb%20%3D%2050.5%7D)
with the value of
in hand, we find
and
:
![a = 5b = 5(50.5)](https://tex.z-dn.net/?f=a%20%3D%205b%20%3D%205%2850.5%29)
![\boxed{a = 252.5}](https://tex.z-dn.net/?f=%5Cboxed%7Ba%20%3D%20252.5%7D)
and for ![c:](https://tex.z-dn.net/?f=c%3A)
![c = 2 b = 2 (50.5)](https://tex.z-dn.net/?f=c%20%3D%202%20b%20%3D%202%20%2850.5%29)
![\boxed{c = 101}](https://tex.z-dn.net/?f=%5Cboxed%7Bc%20%3D%20101%7D)
Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
The circumference is 81.681
The formula for circumference is 2 x pi x radius
In order to find the radius you need to divide 26 by 2
26 divide by 2 is equal to 13
2 x 3.14 x 13= 81.681 or 26pi
Answer:
Step-by-step explanation:
The water has to be 100% - 60% = 40%
100% represents both water alcohol (I think that's what you meant).
40% of 250 = 40/100 * 250 = 10000/100 = 100 mL
So 100 mL = water
150 mL = alcohol.
