??/? Im confused? i would help if you had more information?
Let the number of nickels be n, then the number of quarters is 84-n.
The value of 1 qtr is 25c and the value of 1 nickel is 5c.
The total value is 5n+25(84-n)=1240 (in cents).
5n+2100-25n=1240, 20n=860, n=860/20=43.
So there are 43 nickels (worth $2.15) and 41 quarters (worth $10.25).
The correct answers would be 32 and 12.
32 + 12 = 40, and 32 - 12 = 20. Hope this helps! Have a great day!

Answer: 254.34 ^ 2
Step-by-step explanation:
To find the area of the circle use its formula
A = Pi * R^2 / Area equals pie times radius squared
The two circles diameter combined is 18 meaning the radius is 9
So we plug 9 into the formula
A = 3.14 * 9^2
A = 3.14 * 81
A = 254.34 ^ 2
