A $5,$10,$20,$50, or $100 bill is mapped to all the sets of coins that are the same as the total value of the bill. Tell whether this situation represents a function. Explain your reasoning. If the situation represents a function, give the domain and range.

Answers

Answer:

This situation represents a function. The domain is {A, B, C, D, E} and the range is {$5, $10, $20, $50, $100}.

Step-by-step explanation:

Firstly, we need to know what a function is:

It is simply something that relates an input to an output. Like for instance a mirror is a function that relates your face to your image. In lay terms we can call something a function if and only if it can relate one thing to another. Mathematically, a function is called a function if and only if every input has a distinct output, just as how one face can't produce two images at a time when looked at the mirror. The input is called the domain and output range.

Now, in the question we are told that all the bills are mapped – related in lay terms – to some set of coins that are exactly the same number of the bills. This means each bill has a distinct input. Here is a clearer picture:

A to 5 usd

B to 10usd

C to 20usd

D to 50usd

E to 100usd

Where A, B, C, D and E respectively stand for the distinct coins that are mapped to the distinct bill.

From here, each coin has it distinct output. Therefore it is a function.

The domain is {A, B, C, D, E} and the range is {$5, $10, $20, $50, $100}.

Please solve the equation

Answers

Answer:

Step-by-step explanation:

First, you need to find 3% of £2000

£2000 ÷ 100 = 20

20 x 3 = £60

Since you gain £60 per year, you gain £120 for two years

£2000 + £120 =

-4 5/1 - 6 4/6=??? help!

Answers

Answer:

-15 2/3.

Step-by-step explanation: First off, I performed the equation -4 5/1 - 6 4/6, yielding -15.6. I then translated that to a fraction. How to do that, you ask?

Example #1

Convert 0.32 to fraction:

0.32 = 32/100

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(32,100) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

0.32 = (32/4) / (100/4) = 8/25

Example #2

Convert 2.56 to fraction:

2.56 = 2+56/100

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(56,100) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

2+56/100 = 2 + (56/4) / (100/4) = 2+14/25  

In your problem the final answer would result in -15 2/3. Hope this answered your question.

Answer:

44

Step-by-step explanation:

-4 5/1 - 6 4/6 turn them into fractions you should get -20/1 - 144/6 then to subtract you have to have a comen denominater and it is 6 so 144/6 is okay but you need to do -20/1 x 6 and you get 120/6 so now we have -120/6 - 144/6 = 44 because a negitive and a negitive make a positive.

In a weighted average, some values are worth more than others in computing an average value. A teacher gives a quiz, a test, and a final exam. The expression $\frac{q+3t+5f}{9}$ gives the weighted average of the scores where $q$ is the quiz score, $t$ is the test score, and $f$ is the final exam score. What is the weighted average for a student who scores 86 on the quiz, 75 on the test, and 80 on the final exam?

Answers

Answer:

The weighted average score of the student is 79

Step-by-step explanation:

Here, we want to calculate the weighted average score for the student.

To calculate this, we shall be using the given expression;

The expression to calculate the weighted average score is given as;

(q + 3t + 5f)/9

Thus using the scores of the student, we have;

(86 + 3(75) + 5(80))/9

= (86 + 225 + 400)/9 = 711/9 = 79

Mrs. Snell's math test has twenty questions and is worth 100 points. The test consists of multiple choice questions worth 3 points each and short answer questions worth 11 points each. How many multiple choice questions are on the test? Explain how you determined your solution.

Answers

Answer:

The number of multiple-choice questions are 15.

Step-by-step explanation:

Mrs. Snell's math test has twenty questions and is worth 100 points.  

The test consists of multiple-choice questions and short answer questions.

Let M represents the Multiple choice questions.

Let S represents the short answer question.

It is given that the total number of question are 20.

[tex]S+M=20[/tex]    ...(1)

Also, multiple-choice questions worth 3 points each, and short answer questions worth 11 points each. The total worth of the test is 100 points.

[tex]11S+3M=100[/tex]    ...(2)

Multiply equation (1) by 3 and subtract from equation (2).

[tex]11S+3M=100\\3S+3M=60\\\underline{-\:\:\: -\:\:\:\:\:\:\:\:-\:\:\:\:\:\:}\\8S\:\:\:\:\:\:\:\:\:\:\:\:\:=40\\S\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=5[/tex]

The total number of short answers is 5.

Put S=5 in equation 1.

[tex]5+M=20\\M=15[/tex]

Hence, the number of multiple-choice questions are 15.

It is also the best way to hang onto the ball when you've got it. Second, attack the boards. Games are decided by rebounds. Third, pressure your opponent.
