1. A small box in the shape of a cube for packaging has a volume of 64 cubic inches.
(a) For a medium box, the length, width, and height are all doubled. What is the ratio of the sides, area of the bases, and volumes of the boxes? Show your work.
(b) What is the volume of a medium box? Show your work.
Answer:
b) the volume is 512"^3
a) the side and base ratio is 16/64 1/4
the volume ratio is 64/512 1/8
Step-by-step explanation:
the small boxes dimensions are 4 by 4 by 4
the base and sides are 16"^2
the volume is 64"^3
the medium boxes are 8 by 8 by 8
the base and sides are 64"^2
the volume is 512"^3
the side and base ratio is 16/64 1/4
the volume ratio is 64/512 1/8
The wholesale price for a shirt is $3.50 . A certain department store marks up the wholesale price by 90 %. Find the price of the shirt in the department store.
Answer: $6.65
Step-by-step explanation:
The price of the shirt in the department store = wholesale price + 90% of wholesale price
= 3.50 + (3.50*90)/100
= 3.50 + 3.15
= 6.65
Therefore, the price of the shirt is $6.65

9. Blake is putting carpet in a large
room. He has enough carpet to cover
50 square meters of floor. If Blake
first decides on the length of the
rectangle he's going to cover, the
equation below will tell him what the
width of the rectangle can be.
The equation that will tell him what the width of the rectangle can be is w = 50m² / length.
What equation represents the width of the rectangle?
A rectangle is a 2-dimensional quadrilateral with four equal right angles. A rectangle has two diagonals that are equal in length and bisect each other.
Area of a rectangle = length x width
Width = area / length
width = 50m² / length.
