Answer:
11.6 Inches
Step-by-step explanation:
Let the dimensions of the box be l,w and h
The length of a box is four-and-a-half inches more than its height; written as:
The width of the box is seven inches more than it’s height; written as:
Making h the subject of the formula, we have:
Volume of the box = 4981.5 cubic inches
Volume of a cuboid =lwh
Substituting the given values above:
Therefore,
Height of the box, h=w-7=18.6-7=11.6 Inches
Answer:
x = 20%
Step-by-step explanation:
The area is the product of side lengths. If the original side is "a", then the one increased by 25% is ...
a + 0.25·a = 1.25a
The one decreased by x is ...
a -x·a = a(1 -x)
We want the area of the square to be the same as that of the rectangle, so we write an equation that says that, then solve for x.
square area = rectangle area
a^2 = (1.25a)(a)(1-x)
1 = 1.25 -1.25x . . . . divide by a^2, eliminate parentheses
1.25x = 0.25 . . . . . add 1.25x -1
x = 0.25/1.25 = 0.20
x = 20% . . . . . . expressed as a percentage
The small dish costs $2 each and the large dish costs $4 each,
2(3)+4(2)=6+8=14
2(4)+4(1)=8+4=12
