John bought a pack of 18 cards for $2.99. About how much did each card cost?

Answers

Answer:

0.166

Step-by-step explanation:

Bought 18 cards for $2.99, so you can write it like this:

18 = 2.99

Since you want to find the value of one card, u could write that like this:

1 = x  (where x is the unknown value of 1 card)

To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.

So 2.99/18 = 0.166

therefore x = 0.166

So you can say that each card costs about 17 c

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $1.50. Today they made $135.50 from the 117 wraps sold. How many of the wraps sold were vegetarian?

Answers

Answer:

Number of vegetarian wraps = 80

Number of chicken wraps = 37

Step-by-step explanation:

Let

Number of vegetarian wraps = x

Number of chicken wraps = y

x + y = 117 (1)

x + 1.5y = 135.50 (2)

Subtract (1) from (2) to eliminate x

1.50y - y = 135.50 - 117

0.50y = 18.50

y = 18.50/0.50

y = 37

Substitute y = 37 into (1)

x + y = 117 (1)

x + 37 = 117

x = 117 - 37

x = 80

Number of vegetarian wraps = 80

Number of chicken wraps = 37

In a test consisting of 12 questions, each student gets a score of +23 for every correct answer and −13 for every incorrect answer. Each question must be answered. Ram gets 7 correct and 5 incorrect answers. What's his score?

Answers

Answer:

96 scores

Step-by-step explanation:

Score for each correct answer = +23

Score for each incorrect answer = [tex]-13[/tex]

Each question must be answered such that Ram gets 7 correct and 5 incorrect answers.

Number of correct answers [tex]=7[/tex]

Number of incorrect answers [tex]=5[/tex]

Therefore,

Ram's score [tex]=7(23)+5(-13)=161-65=96[/tex]

Answers

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

X COULD BE 2 OR 7

Step-by-step explanation:

Answer:

A. x= -3

Step-by-step explanation:

firstly collect all the terms . then move the term so it'd look like 5x+14 = -2x - 7 then calculate it then it would look like this : 5x+2x = -7 -14 after you move the terms you again calculate it and then the finish product would look like this : 7x = -21 so after you get that you divide by both sides and the answer is -3 . (im sorry if that don't make sense) but the answer is A.

You need to have a password with 6 letters followed by 3 odd digits between 0 and 9
, inclusive. If the characters and digits cannot be used more than once, how many choices do you have for your password?

Answers

Answer:

9,945,936,000.

Step-by-step explanation:

This is the number of permutations of 6 letters from 26 multiplied by number of permutations of 3 odd digits between 0 and 9.

The total number of odd digits between 0 and 9 are 1,3,5,7,9 = 5.

So the number of choices are

26P6 * 5P3.

=  26!/(26-6)! * 5!/ 2!

= 26!/20! * 5!/2!

= 165765600 * 60

= 9945936000.

The coldest temperature in New York City was -15 on February 9th 1934, The next day the temperature rose 42 degrees. Write an expression for the temperature on February 10th

Answers

Answer:

27°C

Step-by-step explanation:

The temperature on February 9th 1934 = -15°C

The next day the temperature rose 42 degrees.

We need to find an expression for the temperature on February 10th.

February 10th temperature = -15 + 42

= 27°C

So, the temperature on February 10th is 27°C.

Answer: it would be 42+(-15)

A group of friends were working on a student film that had a budget of $1140. They used 65% of their budget on costumes. How much money did they spend on costumes?

Answers

Answer:

They use 741 dollars

Step-by-step explanation:

Write 65% as

65/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

65/100 of 1140 = 65/100× 1140

Therefore, the answer is 741

If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.

Amount of budget spend on costume is $741

Given that;

Total budget of student firm = $1140

Percentage of budget used = 65%

Find:

Amount of budget spend on costume

Computation:

Amount of budget spend on costume = Total budget of student firm × Percentage of budget used

Amount of budget spend on costume = 1,140 × 65%

Amount of budget spend on costume = 1,140 × 0.65

Amount of budget spend on costume = $741

The equation for the price of a baseball card that was bought for 5 dollars and has appreciated 5% yearly. Find the yearly calue of the card 25 years later

Answers

Answer:

The yearly value of the card 25 years later is $16.93.

Step-by-step explanation:

You can use the following formula to find the future value:

FV=PV(1+r)^n

FV= future value

PV= present value= 5

r=rate= 0.05

n=number of periods of time= 25

Now, you can replace the values in the formula:

FV=5(1+0.05)^25

FV=5(1.05)^25

FV=16.93

According to this, the answer is that the yearly value of the card 25 years later is $16.93.

QUESTION 6 of 10: You expect your expenses to grow non-linearly over time by the following formula: expenses = 4,000 + 20,000 x (1.5)
where t is the number of months in business. What are your estimated expenses after 6 months ?
a) $231,813
b) $242,131
c) $277,961
d) $282,918

Answers

Answer:

$231,813

Step-by-step explanation:

The estimated expenses after 6 months is $231,812.5

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

Expense = 4,000 + 20,000 x [tex](1.5)^t[/tex]

Now, for t= 6 months

Expense = 4,000 + 20,000 x [tex](1.5)^6[/tex]

Expense = 4,000 + 20,000 x 11.390625

Expense = 4,000 + 2,27,812.5

Expense = 231,812.5

Hence, The estimated expenses after 6 months is $231,812.5.

Step-by-step explanation:

Given the coordinate points (3, 2) and (3, 6), to get the x intercept, we need to first get the equation of the line passing through the points

Form the coordinate, we can see that the line passes through the points x = 3 on both coordinates. This shows that the line is a horizontal line cutting the x axis at x =3. Hence the x-intercept for the line will be 3
