<u>Answer</u>
∛729
<u>Explanation</u>
The volume of an object is the amount of space that the object can occupy.
The general formula for getting the volume of a regular object is:
Volume = Base area × Height
For a cube, all sides are equal.
∴ Volume of a cube = length × length × length
= (length)³
This means given the volume of a cube we can get the length of one side as shown.
Volume = (length)³
length = ∛volume.
∴ Volume = 729 in³
Length = ∛729 inches. This will give you the number of cubes 1 inches can fit along one side.
<span>The expression representing the complement of an angle (x):
(90 - x)
:
The expression representing the supplement of an angle (x)
(180 - x)
:
"the complement of an angle is 18 degrees more than 1/3 its supplement."
(90 - x) = (180-x) + 18
:
90 - x = 60 - x + 18; found one third of 180
:
90 - x = 78 - x
:
90 - 78 = -x + x
:
12 = +x
Multiply equation by 3 to get rid of the denominator
3(12) = 3*x
36 = 2x
x =
x = 18 degrees</span>
Answer:
15x is your answer. Hope this helps.
Answer: There are 30 questions.
Step-by-step explanation:Easiest way to approach this is to remember the percentage proportion equation. Part/Total= percentage/100.
27/x = 90/100
27/x=.90
x=27/.90
x=30
Therefore the exam has 30 questions.
