The volume of a cone is V = (1/3)*pi*h*r^2
V = (1/3)*3.14*8*12^2 = 1206 cu.cm
9/20
A percentage is the same as showing a number over 100 and if we multiply 20 by 5 we get 100. So if we multiply 9 by 5 we get 45, giving us 45/100 which can be shown as 45%.
As a decimal, well if we say 100% equals 1.0, then 45% equals 0.45
Answer:
c = $130
Step-by-step explanation:
Given:
c = 100 + 0.30m
Where,
c = cost of renting a car (in dollars)
m = number of miles driven (in miles)
If m = 100 miles
c = 100 + 0.30m
= 100 + 0.30(100)
= 100 + 30
= 130
c = $130
Answer:
1
Step-by-step explanation:
√4x+1=3
√4x = 3 - 1
√4x = 2
squaring both sides,
(√4x)² = 2²
4x = 4
x = 4/4
x = 1
