Answer:
Part 1) The volume of the storage body is 576 cubic feet
Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box
Part 3) Sheila can fit 64 boxes into the truck
Step-by-step explanation:
step 1
Find the volume of the storage body
we know that
The volume of the of the storage body is equal to the volume of two rectangular prism
The volume of a rectangular prism is equal to

First rectangular prism (top)

Second rectangular prism (bottom)

The volume of the storage body is

step 2
we know that
To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box
step 3
substitute the given values

therefore
Sheila can fit 64 boxes into the truck
Answer:
4. 54- 8.5x>20
Step-by-step explanation:
Catherine only has $54, so she cannot spend more than that.
The canvas will cost at least $20, but we don't know how much exactly.
The tubes cost $8.50 each.
So, she starts with a total budget of $54, out of which she will buy paints (8.5x) and she wants to have at least $20 left for canvas.
So, we transpose those facts into the inequity:
54 - 8.5x > 20

Answer:
x^2/9 +(y +2)^2/49 = 1
Step-by-step explanation:
For center (h, k), and x- and y-semi-axis lengths a and b, respectively, the equation is ...
((x -h)/a)^2 +((y -k)/b)^2 = 1
The given ellipse has center (0, -2) and semi-x-axis length 3 and semi-y-axis length 7. Thus the equation is ...
(x/3)^2 +((y +2)/7)^2 = 1
This might conventionally be written as ...
x^2/9 +(y +2)^2/49 = 1
