In order to develop a more appealing cheeseburger, a franchise uses taste tests with 12 different buns, 7 different cheeses, 4 types of lettuce, and 3 types of tomatoes. If the taste tests were done at one restaurant by one tester who takes 10 minutes to eat each cheeseburger, approximately how long would it take the tester to eat all possible cheeseburgers?

It will take a week to taste all the cheeseburgers possible.

Step-by-step explanation:

Given:

Number of buns of different types = 12

Number of cheeses of different types = 7

Number of lettuce of different types = 4

Number of tomatoes of different types = 3

Time taken to eat one cheeseburger = 10 minutes

To find:

Total time taken to eat all the possible cheeseburgers = ?

Solution:

First of all, we need to find out what all possible number of cheeseburgers can be made using the given number of ingredients.

Total number of possible ways to make cheeseburgers = Number of choices of buns Number of choices of cheeses Number of choices of Lettuces Number of choices of tomatoes

And this number of choices are nothing but the number of types of ingredients available.

So, total number of cheeseburgers possible = 12 7 4 3 = 1008

Time taken to eat 1 cheeseburger = 10 minutes

Time taken to eat 1008 cheeseburger = 10 1008 = 10080 minutes = 168 hours = 7 days

i.e. It will take a week to taste all the cheeseburgers possible.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
