Answer:
- 340 quarters
- 1020 dimes
- 1031 nickels
- 2062 pennies
Step-by-step explanation:
x is the number of quarters
__
a) d = 3x . . . . . . the number of dimes is 3 times the number of quarters
b) n = d + 11 = 3x +11 . . . . there are 11 more nickels than dimes
c) p = 2n = 2(3x +11) = 6x +22 . . . . there are twice as many pennies as nickels
d) The total number of coins is ...
x + d + n + p = 4453
x + (3x) +(3x +11) +(6x +22) = 4453
13x +33 = 4453
13x = 4420
x = 4420/13 = 340 . . . . number of quarters collected
3x = 1020 . . . . . . . . . . . .number of dimes collected
1020 +11 = 1031 . . . . . . . number of nickels collected
2·1031 = 2062 . . . . . . . . number of pennies collected
There were 340 quarters, 1020 dimes, 1031 nickels, and 2062 pennies collected.

![y = {x}^{2} - 2](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%202)
Step-by-step explanation:
because it's has two zeroes
hence it is known as the quadratic function
I am assuming you need to find the volume since you need to find the amount of water. In real life the amount of water would be more than the volume of the ice. But as an estimate we can use volume.
To find the volume you multiply the 3 dimensions- length, width and height. 20 times 20 is 400. 400 times 20 is 8000 mm. So about 8000 mm water was needed.
