Answer:
The answer is "$238".
Step-by-step explanation:
Current worth
depreciates by in 3 years.
time= 19 years
depreciates rate=?
Using formula:
calculates depreciate value in 3 year
so,
depreciates rate= 20%
Answer:
He won 4 games
Step-by-step explanation:
Percentage of games he lost= 75%
Let the total number of games be
75% of = 12
= 12
75= 12 x 100
=
=16
Number of games he won = 16-12
= 4
Answer:
a
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = πr²h ( r is the base radius and h the perpendicular height )
To calculate the height h use the right triangle formed by the radius and the inclined side.
Given diameter = 22, then r = 22 ÷ 2 = 11 cm
Using Pythagoras' identity on the right triangle, then
h² + 11² = 61² , that is
h² + 121 = 3721 ( subtract 121 from both sides )
h² = 3600 ( take the square root of both sides )
h = = 60
Thus
V = π × 11² × 60
= 3.14 × 121 × 60 ≈ 22796.4 cm³ → a
