How to convert fractions to decimals video?
garik1379 [7]
I do not have a video but to convert a fraction to a decimal, you divide the numerator by the denominator or make the denominator equal to one hundred. For example, to convert 1/5 to a decimal, you write 1/5 as 20/100, which as a decimal is written as .2

Find a formula for the inverse of the function. f(x)=1-2/x^3.
Elena-2011 [213]
       f(x) = 1 - ²/ₓ₃
          y = 1 - ²/ₓ₃
          y = 1 - ²/ₓ₃
      y - 1 = ⁻²/ₓ₃
      x - 1 = -2/y³
 y³(x - 1) = -2
         y³ = ⁻²/ₓ₋₁
          y = ∛⁻²/ₓ₋₁
          y = -∛(2x² - 4x + 2)/x - 1
      f⁻¹(x) = -∛(2x² - 4x + 2)/x - 1

Celine ate brunch at a restaurant. The bill came to $72.80. If she left a 15% tip, what was the total cost of her brunch?
DedPeter [7]

Answer:

<em>$83.69</em>

Step-by-step explanation:

Given the following

Initial Cost of the brunch = $72.80

Percentage tip = 15%

Tip paid = 15% of $72.60

Tip paid = 0.15 * 72.60

Tip paid = $10.89

Total cost of brunch =  $72.80 + $10.89

Total cost of brunch = $83.69

<em>Hence the total cost of her brunch is $83.69</em>
