Answer:
66 minutes
Step-by-step explanation:
11.96 - 8 =3.96
Every 10 minutes Deon pays 60 cents because 6 times 10 = 60 and every 6 minutes Deon is paying 36 cents
10 min = 60 cents
20 min = $1.20
40 min = $2.40
50 min = $3.00
60 min = $3.60
6 min = 36 cents
Then you do 3.60 + 36 which equals $3.96
How to figure how the minutes is just 60 + 6 = 66 minutes
The surface area of a sphere is given by
We deduce
So, in your case, the radius is
The volume of a sphere is given by
So, we have
Times 2nd equation by 2
add to first equation
3x+6y=6
<u>4x-6y=8 +</u>
7x+0y=14
7x=14
divide both sides by 7
x=2
sub back
2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0
(x,y)
(2,0)
