Autumn creates bracelets as a hobby and is planning to start selling them online for $10 per bracelet. Autumn has already sold 5 custom bracelets. Her bracelets are so popular that she expects to sell every bracelet that she makes. Write an equation for the amount of money Autumn makes. If Autumn makes and additional 24 bracelets, how much money will she make?

Answers

Answer 1

Answer:

(24*10)+50=290

Step-by-step explanation:

Answer 2

a) The equation for the amount of money Autumn makes is y = 10x , where x is the number of bracelets she sells and y is the total amount

b) The amount Autumn makes is $ 290

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

a)

Let the number of bracelets Autumn sells be = x

Let the cost of one bracelet be = $ 10

Now , the equation will be

So , the cost of x number of bracelets y = number of bracelets x cost of one bracelet

The cost of x number of bracelets y = 10x

So , the equation is y = 10x

b)

The equation is y = 10x

The cost of 5 bracelets = 10 x 5

                                       = $ 50

Now , the cost of 24 bracelets = 24 x 10

                                                  = $ 240

So , the total amount Autumn makes = cost of 5 bracelets + cost of 24 bracelets

The total amount Autumn makes = 240 + 50

                                                       = $ 290

Hence ,

a) The equation for the amount of money Autumn makes is y = 10x , where x is the number of bracelets she sells and y is the total amount

b) The amount Autumn makes is $ 290

if 3a-2b=8 and a+3b=7 what is the value of 4a+b

Answers

Answer:

Step-by-step explanation:

If a +  3b =  7, subtract 3b from both sides of the equation

       -3b  = -3b       then you get

   a = 7-3b        now plug this into the other equation: 3a-2b=8

3(7-3b) -  2b = 8

21 - 9b  - 2b = 8

21 - 11b = 8           add 11 b to both sides

   + 11b    +11b

21 = 8 + 11b          subtract 8 from both sides

-8    -8

13 = 11b

What is 4a+b?

4(7-3b) + b =

(28 - 12b) + b =

28-11b   (from above 13=11b)

28 - 13 = 15

Which statement is true about the graphs of the two lines y =-4/5x+
2 and y=-5/4x-1/2?

Answers

Answer: Choice C) neither parallel, nor perpendicular, -4/5 and -5/4 are not opposite reciprocals.

The slopes are the only thing we care about when it comes to determining if the lines are parallel or perpendicular. The y intercepts do not affect the answer, so we can ignore them entirely.

The slopes of the two given equations are -4/5 and -5/4. Note how they are both negative. This means that we do not have perpendicular lines. One slope must be positive and the other negative, for perpendicular lines to form.

Another way to see it: the two slopes must multiply to -1 to have perpendicular lines form. We see that (-4/5)*(-5/4) = 1 instead.

Yet another way to see it: The term "opposite reciprocals" means we flip the fraction and we flip the sign (from positive to negative). The reciprocal part happens, but the sign change does not happen.

The lines are not parallel because the slopes would have to be equal for that to happen.

Suppose that a coin is tossed three times and the side showing face up on each toss is noted. Suppose also that on each toss heads and tails are equally likely. Let HHT indicate the outcome heads on the first two tosses and tails on the third, THT the outcome tails on the first and third tosses and heads on the second, and so forth. (a) Using set-roster notation, list the eight elements in the sample space whose outcomes are all the possible head-tail sequences obtained in the three tosses.

Answers

Answer:

S={HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

Step-by-step explanation:

As can be seen in the Sample Tree attached, the eight elements in the sample space whose outcomes are all the possible head-tail sequences obtained in the three tosses are:

S={HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

When tossing a coin three times, there are 8 possible outcomes listed as HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT. These elements represent all possible head-tail sequences for three coin tosses.

When a coin is tossed three times, each outcome is a sequence of heads (H) and tails (T). Since there are two possible outcomes for each toss, the total number of possible sequences is 23 = 8. Let's list these sequences using set-roster notation.

The sample space is:

HHHHHTHTHHTTTHHTHTTTHTTT

These elements cover all possible outcomes where each toss can either result in heads or tails.

O A. The solution set is { } (Type an ordered pair.)
O B. There are infinitely many solutions.
O C. There is no solution.

Answers

Answer:

A) The solution set is (6,-8).

Step-by-step explanation:

3x - y = 26

-3x       - 3x        Subtract 3x from both sides

-y = -3x + 26     Divide both sides by -1

y = 3x - 26

Now plug this into 7x + 8y = -22 to solve for x

7x + 8(3x - 26) = -22        Distribute

7x + 24x - 208 = -22       Combine like terms

31x - 208 = -22

     + 208    + 208            Add 208 to both sides

31x = 186                           Divide both sides by 31

x  = 6

Plug this into y = 3x - 26 to solve for y

y = 3(6) - 26           Multiply

y = 18 - 26              Subtract

y = -8

If this answer is correct, please make me Brainliest!

Final answer:

The system of equations is solved using the substitution method, resulting in x = 6 and y = -8. Hence, the correct choice is the ordered pair (6, -8).

Explanation:

To solve the system of equations by the substitution method, let's start by solving the second equation for y:

3x - y = 26
=> y = 3x - 26.

Now, substitute this expression for y into the first equation:

7x + 8(3x - 26) = -22
=> 7x + 24x - 208 = -22
=> 31x = 186
=> x = 6.

Now, substitute x back into the expression we found for y:

y = 3(6) - 26
=> y = 18 - 26
=> y = -8.

The solution to the system is the ordered pair (6, -8), which means the correct choice is:

O A. The solution set is { (6, -8) } (Type an ordered pair.)

Which of the following shows the extraneous solution to the logarithmic equation below? log Subscript 3 Baseline (18 x cubed) minus log Subscript 3 Baseline (2 x) = log Subscript 3 Baseline 144

Answers

The extraneous solution of the logarithmic problem log₃( 18x³) -log(2x) = log₃144 is -4.

What is Logarithm?

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]a^c = b[/tex] can be written as,

log[tex]_a[/tex]b = c

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

Solving the function using the basic logarithmic value, we get,

log₃( 18x³) -log(2x) = log₃144

log₃ (18x³/2x) = log₃144

log(9x²) = log₃144

Take antilog.

9x² = 144

x = ±4

If we solve further we will get that the value of x can be either -4 or 4, if take the value of x as -4, in the beginning then you will get log₃(18(-4)³) as the log of negative value which is impossible.

Hence, x=-4 is an extraneous solution for the given expression log₃( 18x³) -log(2x) = log₃144.

of 100 students, 32 are taking Calculus, 29 are taking French, and 13 are taking both Calculus and French, if a student is picked at random
what is the probability that the student is taking Calculus or French?
(Reduce fraction to lowest form)​

Answers

Answer:The probability that the student is taking Calculus or French =  [tex]\frac{12}{25}[/tex]

Step-by-step explanation:

The total number of students = 100

Let A represents calculus and B represents French

The no of students taking calculus = 32

The no of students taking French = 29

The no of students taking calculus and french = 13

the probability that the student is taking Calculus or French = ?

P (AUB) = P(A) + P(B) - P(A∩B)

= [tex]\frac{32}{100}[/tex] + [tex]\frac{29}{100}[/tex] - [tex]\frac{13}{100}[/tex]

= [tex]\frac{48}{100}[/tex]

Reducing to lowest fraction,  it becomes [tex]\frac{12}{25}[/tex]

The probability that the student is taking Calculus or French =  [tex]\frac{12}{25}[/tex]

The probability that a randomly selected student is taking Calculus or French is 12/25.

To find the probability that a randomly picked student is taking either Calculus or French, we use the principles of set theory, specifically the formula for the union of two sets:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Here,
A = Students taking Calculus = 32
B = Students taking French = 29
A ∩ B = Students taking both Calculus and French = 13
Total students = 100

The formulas for the probabilities are:
P(A) = 32/100
P(B) = 29/100
P(A ∩ B) = 13/100

Now substitute these values into the union formula:

P(Calculus or French) = 32/100 + 29/100 - 13/100 = 48/100 = 12/25

Therefore, the probability that a randomly picked student is taking either Calculus or French is 12/25.

An initial population of 7 chipmunks in Mary's yard increases by 6% each year. If the function f(x) = abx models this situation, what is the population of the chipmunks in 5 years? (to the nearest whole number)

Answers

Answer: there would be 9 chipmunks after 5 years.

Step-by-step explanation:

An initial population of 7 chipmunks in Mary's yard increases by 6% each year. It means that the population is increasing in an exponential rate.

The function that models the situation is expressed as

f(x) = ab^x

Where

a represents the initial population of chipmunks

b represent the rate of growth

x represent the number of years

From the information given,

a = 7

b = 1 + 6% = 1 + 6/100 = 1.06

x = 5 years

After 5 years,

f(5) = 7 × 1.06^5

f(5) = 9

A Broadway theater has 400 seats, divided into orchestra main, and balcony seating. Orchestra seats sell for $70, main seats for $45, and balcony seats for $35. If all the seats are sold, the gross revenue to the theatre is $18,800. If all the main and balcony seats are sold , but only half the orchestra seats are sold, the gross revenue is $16,000. How many are there of each kind of seat.

Answers

Answer:

-80 orchestra seats

-200 main seats

- 120 balcony seats

Step-by-step explanation:

Let x b number of orchestra seats

Let y be number of main seats

Let z be number of balcony seats.

Thus, we have the following equations;

For all seats sold;

70x + 45y + 35y = 18,800 - - - - eq1

For half of orchestra sold;

70•½•x + 45y + 35y = 16,000 - - eq2

For total seats;

x + y + z = 400 - - - - eq3

Solving eq1, eq2 and eq3 simultaneously, we have;

x = 80

y = 200

z = 120

Thus, we have;

-80 orchestra seats

-200 main seats

- 120 balcony seats

Which mathematical terms originated from the Arabic mathematician, al-Khwarizmi

Answers

Answer:

algorithm

Step-by-step explanation:

It sounds like algorithm.

The mathematical terms that originated from the Arabic mathematician, al-Khwarizmi, are ""algorithm"" and ""algebra.""

Al-Khwarizmi was a Persian mathematician and astronomer who lived in the 8th and 9th centuries. His works were instrumental in the development of algebra and the use of Hindu-Arabic numerals. The term ""algorithm"" is derived from a Latinization of his name, Algoritmi, and originally referred to the numerical methods he described in his treatise on arithmetic.

The word ""algebra"" comes from the Arabic word ""al-jabr,"" which appears in the title of his book ""Kitab al-Jabr wa-l-Muqabala"" (The Compendious Book on Calculation by Completion and Balancing). This book laid the foundations for algebra as a branch of mathematics, and the terms he introduced are still in use today to describe mathematical procedures and the study of equations and algebraic structures.

A television station shows commercials for 13/12 minutes each hour. How many 45-second commercials can it show?

Answers

The television station can show 1 full 45-second commercial during the 13/12 minutes of advertising time allocated each hour.

The question involves calculating how many 45-second commercials can be shown during the 13/12 minutes of advertising time allocated by a television station each hour. To solve this, we first need to convert the minutes to seconds and then divide by the length of one commercial.

13/12 minutes is equal to 13/12 × 60 seconds, which gives us 65 seconds of advertising time per hour. One commercial is 45 seconds long. Therefore, the number of 45-second commercials that can be shown is 65 divided by 45.

Divide the total advertising seconds by the duration of one commercial: 65 / 45 = approximately 1.44.

Since we cannot show a fraction of a commercial, the television station can show 1 full 45-second commercial per hour.

A biologist is studying the effects that applying insecticide to a fruit farm has on the local bat population. She collects 23 bats and finds the mean weight of this sample to be 503.4 grams. Assuming the selected bats are a random​ sample, she concludes that because the sample mean is an unbiased estimator of the population​ mean, the mean weight of bats in the population is also 503.4 grams. Explain why this is an incorrect interpretation of an unbiased estimator.

Answers

Answer:

The insufficient or relatively small size of the random sample does not guarantee the unbiasedness of the sample mean in any statistical study.

Step-by-step explanation:

In Statistics,if the sample mean is an unbiased estimator of population mean,then the expected value of the sample mean is equal or identical to the actual population mean.As the researcher increases the size of the random sample in any statistical study or research, the sample mean increasingly approaches the actual population mean and hence, with increasing sample size with relation to the actual population of the study,the sample mean will become an unbiased estimator of the population mean.In this instance, the biologist has selected only 23 bats for the concerned study which might not be enough considering the entire or actual local bat population. Therefore, even a random sampling of 23 bats will not necessarily ensure that the sample mean will be an unbiased estimator of the population mean, in this case. Hence, the biologist would have to increase the size of the random sample to establish the unbiasedness of the sample estimate or the mean.

Andy invests $500 into an account with 4.8% interest, compounded continuously. How much will be in the account in 10 years?

Answers

Answer:

The Correct answer:

$799.06

Final answer:

To find out how much Andy will have in his account after 10 years with a 4.8% interest compounded continuously, we use the formula A = Pe^{rt}. Substituting the values, we find that the amount will be approximately $808.85.

Explanation:

To calculate how much Andy will have in his account in 10 years with an initial investment of $500 at a 4.8% interest rate compounded continuously, we use the formula for continuous compounding, which is A = Pert, where A is the amount of money accumulated after n years, including interest, P is the principal amount, r is the annual interest rate (decimal), and t is the time in years.

Using the given values:

P = $500

r = 4.8% or 0.048

 t = 10 years

Let's compute the final amount:

A = 500 * e^0.048 * 10

Now we calculate the exponent:

e^0.48 (approximately 1.6177)

And then the final amount:

A = 500 * 1.6177 ≈ $808.85

After 10 years, the amount in Andy's account, compounded continuously at a rate of 4.8%, will be approximately $808.85.

Answer:

Cathy is asked to find the length of AC. She could use the Pythagorean Theorem and AC^2 = 3^2 + 2^2. What other formula could she use?

A) (0 + 3)^2 - (1 + 3)^2

B) (0 + 1)^2 - (3 + 3)^2

C) (0 - 3)^2 + (1 - 3)^2

D) (0 - 1)^2 + (3 - 3)^2

Option C is the right choice.

Step-by-step explanation:

Given:

Cathy have used Pythagoras formula to find the hypotenuse.

Hypotenuse of the right angled triangle = AC

We know that:

In right angled triangle:

Hypotenuse square (h)^2 = Square of one side (p)^ + Square of another sides (b)^

⇒ [tex]h^2=p^2+b^2[/tex]

In Cathy's calculation:

⇒ [tex]AC^2=3^2+2^2[/tex]

⇒ [tex]AC^2=9+4[/tex]

⇒ [tex]AC^2=13[/tex]

We have to look for another equation.

Lets see the options individually.

A. [tex]AC^2=(0 + 3)^2 - (1 + 3)^2= 9-16 = 7[/tex]

B. [tex]AC^2=(0 + 1)^2 - (3 + 3)^2=1-0 =1[/tex]

C. [tex]AC^2=(0 - 3)^2 + (1 - 3)^2 =9+4=13[/tex]

D. [tex]AC^2=(0 - 1)^2 + (3 - 3)^2=1+0 =1[/tex]

So,

The other formula Cathy can use is, C i.e. (0 - 3)^2 + (1 - 3)^2 .

Option C is the right choice.

The correct answer is option  C) (0 - 3) + (1 - 3)

If AC is the hypotenuse, and the lengths of the other two sides are 3 and 2, then AC = 3 + 2.

 However, Cathy can also use the distance formula, which is derived from the Pythagorean Theorem. The distance formula calculates the distance between two points in a coordinate plane. If we have two points (x1, y1) and (x2, y2), the distance d between these points is given by:

d = (x2 - x1) + (y2 - y1)

Given that one endpoint of AC, let's call it A, is at (0, 3) and the other endpoint, let's call it C, is at (1, -3), we can apply the distance formula to find AC:

AC = (1 - 0) + (-3 - 3)

AC = (1) + (-6)

AC = 1 + 36

AC = 37

Therefore, the length of AC is the square root of 37, which is 37.

Let's evaluate the other options to see why they are incorrect:

A) (0 + 3) - (1 + 3): This formula would calculate the difference between the squares of the distances from the origin to two points, which does not correspond to the distance between two points.

B) (0 + 1) - (3 + 3): Similar to option A, this formula calculates the difference between the squares of the distances from the origin to two points, which is not the correct application of the Pythagorean Theorem for finding the distance between two points.

D) (0 - 1) + (3 - 3): This formula incorrectly calculates the distance by subtracting the y-coordinates instead of the x-coordinates and does not account for the difference in x-coordinates properly.

Thus, the correct formula to use, other than the direct application of the Pythagorean Theorem, is the distance formula, which in this case is option C) (0 - 3) + (1 - 3).
