39 packages.
Because he sets aside 10, he has $15 left.
15 divided by $0.38 = 39.4736, however he cannot but a fraction of a package so you round down to 39.
Answer:
Round to the nearest 10th
Step-by-step explanation:
We have that
<span>Y = [x³ + (x+2)³ + (x+4)³]/24
y = 3x + 6
f(x)=</span>[x³ + (x+2)³ + (x+4)³]/24
g(x)=3x + 6
using a graph tool
see the attached figure
the solution of the system are
x1=-6
x2=-2
x3=2
the solution are the points
(-6,-12)
(-2,0)
(2,12)

Answer:
28.5 feet
Step-by-step explanation:
A water tower casts a shadow that is 24 foot long. A 9.5 foot tall tree casts a shadow that is 8 foot long. What is the height of the water tower?
The formula is given as:
Height of the tower/Shadow of the tower = Height of the tree/Shadow of the tree
Let the Height of the tower = x
Hence:
x/24 = 9.5/8
Cross Multiply
8x = 24 × 9.5
x = 24 × 9.5/8
x = 28.5 feet
Therefore, the height of the water tower is 28.5 feet
