<h2><u>Question :-</u></h2>

\sf12 \frac{1}{2}  - ( - 4 \frac{1}{2} ) =  \boxed{ ? }

<h3>____________________</h3>

<h2><u>Solution :-</u></h2>

<h3><u>Given Information :-</u></h3>

  • <u>Fraction 1 ➢</u> \sf12 \frac{1}{2}
  • <u>Fraction 2 ➢</u> \sf -4 \frac{1}{2}
  • <u>Operation</u><u> </u><u>➢</u> Subtraction

<h3><u>To Find :-</u></h3>

  • The difference between two fractions

<h3><u>Calculation :-</u></h3>

\sf: \implies  \sf12 \frac{1}{2}  - ( - 4 \frac{1}{2} ) =  \boxed{ ? }

<em><u>Firstly, converting mixed fractions to improper fractions, We get,</u></em>

\sf:  \implies  \frac{25}{2}  - ( -  \frac{9}{2} ) =   \boxed?

<em><u>Now, solving the parentheses, We get, </u></em>

\sf:  \implies  \frac{25}{2}  +  \frac{9}{2}  =  \boxed ?

<em><u>Since, We have like terms, We will directly add up the two fractions, We get, </u></em>

\sf:  \implies \frac{25 + 9}{2}  =   \boxed?

<em><u>Calculating further, We get, </u></em>

\sf:  \implies  \frac{34}{2}  =   \boxed?

<em><u>Bringing the fraction to it's lowest terms, We get, </u></em>

\sf:  \implies  \frac{ \cancel{34}  \:  \: \tiny{7}}{ \cancel2}  =  \boxed7

\sf :\implies \sf12 \frac{1}{2}  - ( - 4 \frac{1}{2} ) =  \red{ \boxed{ \bf7 }}

<h3>____________________</h3>

<h2><u>Final Answer :-</u></h2>

  • \sf  \sf12 \frac{1}{2}  - ( - 4 \frac{1}{2} ) =  \red{ \boxed{\bf7 }}

assuming that no questions are left unanswered, in how many ways can a six-question quiz with 4-choice multiple choice questions
AfilCa [17]

Given:

Total number of questions = 6

Choice for each question (in MCQ) = 4

Assuming that no questions are left unanswered.

To find:

The total number ways to answer the quiz, assuming that no questions are left unanswered.

Solution:

Here, Number of ways to answer each question = 4

To find the  total number ways to answer 6 MCQ, we have to have to multiply number of ways to answer each question 6 times.

Total number of ways to answer six-question quiz with 4-choice multiple choice questions is

4\times 4\times 4\times 4\times 4\times 4=4096

Therefore, the required number of ways is 4096.

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots inclu
Pepsi [2]

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

99.90 + 89.90 = 189.80

Step 2: Find the sales tax of the result

\frac{8}{100}\times 189.8 = 15.184

  • Step 1: Convert 8% to fraction
  • 8\%= \frac{8}{100}
  • Simplify
  • \frac{8}{100} = \frac{2}{25}
  • Step 2: Convert 189.80 to a fraction
  • 189.80 = \frac{189.8}{1}
  • Step 3: Set it up
  • \frac{2}{25}\times \frac{189.8}{1}
  • Step 4: Cross divide
  • 189.80 \div 25 = 7.592\\2 \div 1 = 2
  • Step 5: Multiply the result
  • 7.592 \times 2 = 15.184

Step 3: Add the result from the total cost of both items

189.80 + 15.184 = 204.98

The total cost of the hats and boots including sales tax is 204.98 dollars
