asambeis [7]

Answer:

  It compares 3 meals to 1 day.

Step-by-step explanation:

"Unit rate" refers to a rate that has 1 unit in the denominator.

  (3 meals)/(1 day) . . . . "three meals per day"

has one unit (1 day) in the denominator, so that is a unit rate.

-1/2 divided by 1 3/4 as a fraction in simplest form
Helen [10]

\Large\textsf{\textbf{Answer\;:}}}

\large\textsf{refer\:to\:the\:"calculations"\:section\:of\:this\:ans}

\Large\textsf{\textbf{Calculations\::}}

-\displaystyle\frac{1}{2} :1\frac{3}{4}

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

-\displaystyle\frac{1}{2} :\frac{7}{4}

Now turn the fraction you are dividing by over :

-\displaystyle\frac{1}{2} *\frac{4}{7}

Now multiply the numerator of the first fraction times the numerator of the second fraction :

4

Perform the same operation with the denominators :

-4/14

So the result is :

-\displaystyle\frac{4}{14}

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

-\displaystyle\frac{2}{7}

How would I convert this function into an equation ?
vivado [14]

Definition

Functions have zeros or x-values that generate function values equal to zero.

Equations have roots or solutions that can be substituted into the polynomial in order to generate a value equal to zero.

Given:

f(x)\text{ = -}\frac{1}{3}\sqrt[]{x}\text{ + 3}

To convert this to an equation, we set f(x) equal to zero i.e

f(x)\text{ = 0}

The resulting equation is:

-\text{ }\frac{1}{3}\sqrt[]{x}\text{   + 3 = 0}
