She can make 4.
Explanation:
First you gotta find the circumference of the circle which is 37.68
Circumference=Diameter•pi
Pi is 3.14 in case you didn’t know.
Now divide the amount of ribbon she has by the circumference and you get 4.77…
So to make it simple we just say 4 because she wont want to make 4 and a half invitations.

Answer:
a = 20 . . . . liters
Step-by-step explanation:
To solve this, multiply the equation by 30+a:
a = 0.4(30 +a)
a = 12 + 0.4a . . . . . eliminate parentheses
0.6a = 12 . . . . . . . . subtract 0.4a
a = 12/0.6 = 20 . . . divide by the coefficient of a
20 L of alfalfa must be added
_____
<em>Check</em>
20/(30+20) = 20/50 = 40/100 = 0.4 . . . . . . answer checks OK
