Answer: 16 inches
Step-by-step explanation:
Complete question
(A cylindrical container can hold about 1256 cubic inches of water. the diameter of the cylinder is 10 inches long. approximate the height if the cylinder to the nearest inch . Use 3.14 to approximate the value of pi)
Volume of a cylinder = 3.14 * r² * h
r = radius of the cylinder
H = height of the cylinder
Pi = 3.142
Radius = diameter/ 2
R = 10/2 = 5 inches
1256 = 3.14 * 5² * h
1256 = 78.5h
Divide both sides by 78.5 to get h,
H = 1256 / 78.5 = 16 inches
The height of the cylinder is 16 inches
Answer:
180 coins
Explanation:
N = number of nickels (no nickels spent)
D = number of dimes initially saved
D' = number of dimes left after spending
1) N = D + 43
2) D' = D - 17
3) N = 2*D' = 2*(D - 17)
Set equations 1) and 3) equal to each other and solve for D:
D + 43 = 2*(D - 17)
D + 43 = 2*D - 34
D = 43 + 34 = 77
N = D + 43 = 77 + 43 = 120 nickels left
D' = D - 17 = 77 - 17 = 60 dimes left
Total coins left = 120 + 60 = 180 coins (I hope this is not too confusing for you)
Answer: To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
