Step-by-step explanation:
The bar above the 3 indicates the 3 is being repeated, that is
0.13333....
We require to make 2 equations with the repeating 3 after the decimal point.
let x = 0.13333... , then multiply both sides by 10 then 100
10x = 1.3333 ← equation with repeating 3 after the decimal point
100x = 13.3333 ← second equation with repeated 3 after the decimal point
Subtracting the equations eliminates the repeated 3, that is
100x - 10x = 13.333 - 1.333
90x = 12 ( divide both sides by 90 )
x = ← divide numerator/denominator by 6, hence
0.1333... =
Expression for the height of the prism is x + 2
<em><u>Solution:</u></em>
Given that,
To find: height of prism
<em><u>The volume of rectangular prism is given by formula:</u></em>
<em><u>Solving for height we get,</u></em>
<em><u>Substituting the values we get,</u></em>
<em><u>Factor the numerator</u></em>
Cancel the common factors,
Thus expression for the height of the prism is x + 2
