A pack of 12 sodas cost 5.04$ what is the unit rate of each soda

Mathematics

1 answer:

Dovator [93]3 years ago

3 0

For this case we propose the following expression:

x: Variable representing the unit rate of each soda

So: $x = \frac {5.04} {12} \frac {dollar} {soda}\\x = 0.42 \frac {dollar} {soda}$

Thus, 0.42 dollars is paid for each soda.

Answer:

the unit rate of each soda is $0.42 \frac {dolar} {soda}$

The principle is 300 and the rate is 3%and 4 years is the time what is the interest earned and the new balance

Dimas [21]

$\bf ~~~~~~ \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$300\\
r=rate\to 3\%\to \frac{3}{100}\to &0.03\\
t=years\to &4
\end{cases}
\\\\\\ I=300\cdot 0.03\cdot 4$

the new balance is 300 + I.

A greeting card company can sell cards for $2.75 each, so the revenue can be calculated using the formula 2.75 Rx . The company’

LuckyWell [14K]

Given that the revenue equation is $R(x)=2.75x$ and the cost equation is $C(x)=0.35x+12,000$

Part A:

At break-even the cost is equal to the revenue.

Thus, the algebraic equation needed to determine when the company will break even is given by

$R(x)=C(x) \\ \\ \Rightarrow2.75x=0.35x+12,000$

Part B:

The solution to part A is given as follows:

$2.4x=12,000 \\ \\ \Rightarrow x=5,000$

Part C:

<span>The algebraic inequality needed to indicate that the revenue is greater than the cost is given by

$R(x)\ \textgreater \ C(x) \\ \\ \Rightarrow2.75x\ \textgreater \ 0.35x+12,000$

Part D:

</span>The solution to part C is given as follows:

$2.4x>12,000 \\ \\ \Rightarrow x>5,000$

Part E:

The answer in part D tells us that the the company will make a profit when the produce more than 5000 cards.

Select the correct location on the table. Consider the following equations. f(x)= (x^2+3x+2)/(x+8) and g(x)= (x-1)/x. Approximat

zhannawk [14.2K]

Answer:

(b) -61/16 | -15/4

Step-by-step explanation:

We assume you're using a binary search successive approximation technique that starts with an interval and cuts it in half with each iteration. The final approximation of the solution to the equation will be the midpoint of the interval after it has been cut in half 3 times.

The graph shows the intersection point of the curves lies between x = -4 and x = -3.

If we define h(x) = f(x) -g(x), then our first iteration will evaluate h(-7/2) and determine which end of the interval gets replaced. The attachment shows us that the sign of h(-7/2) is the same as the sign of h(-3), so -7/2 replaces -3 and the interval after the first iteration is [-4, -7/2].

The midpoint of this interval is -15/4. The sign of h(-15/4) is the same as the sign of h(-7/2), so the interval after the second iteration is [-4, -15/4].

The midpoint of this interval is -31/8. The sign of h(-31/8) is the same as the sign of h(-4), so the interval containing the solution after the third iteration is [-31/8, -15/4]. The approximate solution value after 3 iterations is (-31/8 -15/4)/2 = -61/16.
