Answer:

<h3>If the taste tester takes 10 minutes to eat a cheeseburger, then it would take him is $3276\times 10 = 32760$ minutes Eating round the clock, it would take him is $\frac{546}{24} = 22 days 18 hours$ </h3>

Step-by-step explanation:

Given that "In order to develop a more appealing cheeseburger, a franchise used taste tests with 13 different buns, 5 different cheeses, 2 type of lettuce, and 3 types of tomatoes"

From the given we can write

13 buns

8 cheese

4 lettuces

3 tomatoes

∴ There would be different cheeseburger combinations is given by

$13\times 8\times 4\times 3 = 3,276$

Given that if the taste tester takes 10 minutes to eat a cheeseburger, then it would take him

$3276\times 10 = 32760$ minutes

Eating round the clock, it would take him

$\frac{32760}{60}=546$ hours

$\frac{546}{24} = 22 days 18 hours$

Answer: $\bold{a=1\qquad b=\dfrac{1}{16}\qquad c=\dfrac{1}{64}\qquad d=1\qquad e=\dfrac{4}{9}\qquad f=\dfrac{16}{81}}$

<u>Step-by-step explanation:</u>

$\begin{array}{c|l}\underline{\quad x\quad}&\underline{\quad 4^{-x}\qquad \qquad}\\-1&4^{-(-1)}=4^1=4\\\\0&4^{-(0)}=4^0=1\\\\2&4^{-(2)}=\dfrac{1}{4^2}=\dfrac{1}{16}\\\\4&4^{-(4)}=\dfrac{1}{4^4}=\dfrac{1}{64}\end{array}$

$\begin{array}{c|l}\underline{\quad \bigg x \quad}&\underline{\quad \bigg(\dfrac{2}{3}\bigg)^x\qquad \qquad}\\\\-1&\bigg(\dfrac{2}{3}\bigg)^{-1}=\dfrac{3}{2}\\\\0&\bigg(\dfrac{2}{3}\bigg)^{0}=1\\\\2&\bigg(\dfrac{2}{3}\bigg)^{2}=\dfrac{2^2}{3^2}=\dfrac{4}{9}\\\\4&\bigg(\dfrac{2}{3}\bigg)^{4}=\dfrac{2^4}{3^4}=\dfrac{16}{81}\end{array}$
