20= -B/0.2
multiply -B/ 0.2 both sides
= -4
Answer:
42.40705%
Step-by-step explanation:
(1 - (23/100)^(19/9) = 1 + r/100
0.57593 = 1 + r/100
r = 42.40705%

And replacing we got:


Answer:
Let x is the number of the cannon and y is the number of the row boat.Thus the equation will become
8x+5y=110
Answer:
V ≈ 62.83
Step-by-step explanation:
<u>Cylinder Formulas in terms of r and h</u>
Calculate the volume of a cylinder:
V = πr2h
Calculate the lateral surface area of a cylinder (just the curved outside):
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr2
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
Solution
V=πr 2h = π · 22 · 5 ≈ 62.83185
Therefore, the volume of the cylinder in the nearest tenths is V ≈ 62.83
