Answer:
A
Step-by-step explanation:
(b-3)(b-3) would equal (b^2–6b+9), when using the foil method.
Answer:
1/4 is the answer
Step-by-step explanation:
1/4 is equal to 25% and 25% is less than 40%
Alright, let get started.
Kyle has a storage box having dimensions 2 ft long, 3 ft high and volume 12 cubic feet.
The formula for volume is = 
Suppose the width is w so,
Dividing by 6 in both sides
w = 2 feet
Myla has a storage box that is 4 ft high and 2 feet long and volume 16 cubic feet.
Suppose the width is w hence
Dividing 8 in both sides
w = 2 feet
Hence the width of Kyle and Myla's boxes, both are 2 feet. : Answer
Hope it will help :)

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
