Answer:
$10
Step-by-step explanation:
x + 5y = $24
x + 5($2.50) = $24
x + $12.50 = $24
x = $24 - $12.50
x = $11.50/2
x = 5
Thus, Harry bought 5 gallons of iced tea which cost him $10.
3 divided by 4 subtract 9 divided by 12 equals 0. Hope this helps
Answer:
I think it's maybe $55.00
Step-by-step explanation:
Answer:
A) A(t) = 4500*π - 1600*t
B) A(4) = 7730 in³
C) t = 8,8 sec
Step-by-step explanation:
The volume of the sphere is:
d max = 30 r max = 15 in
V(s) = (4/3)*π*r³ V(s) = (4/3)*π* (15)³
V(s) = 4500*π
A) Amount of air needed to fill the ball A(t)
A(t) = Total max. volume of the sphere - rate of flux of air * time
A(t) = 4500*π - 1600*t in³
B) After 4 minutes
A(4) = 4500*π - 6400
A(4) = 14130 - 6400
A(4) = 7730 in³
C) A(t) = 4500*π - 1600*t
when A(t) = 0 the ball got its maximum volume then:
4500*π - 1600*t = 0
t = 14130/1600
t = 8,8 sec
