0.05n + 0.1d = 3.10
n + d = 44
d = 44 - n
Substituting to the first equation:
0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26
Obtaining the value of nickels:
26 * 0.05 = 1.3
Therefore, the value of nickels that Bethany has is $1.30

Answer:1
V = 62.1262 cubic inches
Step-by-step explanation:
The formula for volume of a cone is V = (1/3)πr²h where r is the radius of the base, and h is the height.
We are given the height, h = 7 1/2 inches, or 15/2 inches
We are given the diameter of the base of 5 5/8 inches, or 45/8 inches
The radius is half the diameter, so divide 45/8 by 2. The radius is 45/16.
Plug these values into the formula and find V
V = (1/3)π(45/16)²(15/2)
V = 30,375π/1,536 = 62.12622191
rounding to 4 decimal places gives us 62.1262 cubic inches
