Answer:
I believe the answer is 2.22 which is letter c
Step-by-step explanation:
multiply the number of ounces by the price per ounce
Blue jelly beans cost 0.28 per ounce and there are 4 ounces
4 * 0.28 = 1.12
red jelly beans cost 0.55 per ounce and there is 3 ounces
3 *0.55 = 1.65
now add the totals: 1.12 +1.65 = 2.77
this is more than the total they want of 2.20
so it is not reasonable.
The ratio of the number of female attendants to the number of male attendants is 21/17
<h3>Ratio</h3>
- Amount donated by female attendant = $1200
- Amount donated by male attendant = $800
- Average donation = $900
let
- number of female attendant = x
- number of male attendant = y
900 = 1200x + 800y / (x + y)
900x + 900y = 1200x + 800y
900x + 1200x = 800y + 900y
2100x = 1700y
x : y = 2100 / 1700
x : y = 21 ; 17

Answer:
Least number is 60.
Step-by-step explanation:
Let the number of CDs has Jo be represented by x + 10. Where x = 0, 1, 2, 3....
Then, since Ken has twice as many CDs as Jo, the number of CDs that Ken has can be expressed as;
2(x + 10) = 2x + 20
Maisie has three times as many CDs as Ken, then the number of CDs that Maisie has can be expressed as;
3(2x + 20) = 6x + 60
Thus to determine the least number of CDs that Maisie can have, let x = 0.
3(2x + 20) = 6x + 60
= 6(0) + 60
= 60
Therefore, the least number of CDs that Maisie can have is 60.
Answer:
x = - 5, - 6
Step-by-step explanation:
x^2 + 11x + 30 = 0
x^2 + 5x + 6x + 30 = 0
x ( x + 5 ) + 6 ( x + 5 ) = 0
( x + 6 ) ( x + 5 ) = 0
x + 6 = 0
x = - 6
x + 5 = 0
x = - 5
