Bret is starting a business selling handmade necklaces. He has decided to invest and initial amount of $387 for advertising and materials cost seven dollars for each necklace he makes. Bret can sell his creations for $10 per necklace.once he makes and sells a certain number of necklaces he will break even with identical expenses and sales. How many necklaces would that take? What would the total expenses and sales be then?

Answers

Answer 1

alrighty

each necklace costs him 7 dollars but he gets 10 dollars from selling them
so his profit per necklace=10-7=3 per necklace

so we want to find how many necklaces he needs to make and sell to cover the initial investment

the cost is 387
divide it by the profit per necklace
387/3=129
needs to make 129 necklaces
the total expenses would be equal to the total sales
ok, the sales are 10 dollars and 129 necklaces so total sales is 1290 dollars and so then the expenses are 1290 dollars

129 necklaces
total expensese is $1290
total sales is $1290

Answer 2

Final answer:

To break even, Bret would need to make and sell 40 necklaces, with a total expense of $15,760 and total sales of $400.

Explanation:

To determine the number of necklaces Bret needs to make and sell to break even, we need to consider his initial investment and the expenses and sales associated with each necklace.

First, let's calculate the total expenses for each necklace: $7 (materials cost) + $387 (initial investment) = $394.

Next, let's calculate the total sales for each necklace: $10 (selling price).

To break even, the total expenses and total sales need to be equal.

Let n represent the number of necklaces:

Total expenses = $394 * n

Total sales = $10 * n

Setting the two equations equal to each other, we have: $394 * n = $10 * n.

Now, let's solve for n:

$394 * n = $10 * n

$394 = $10

n = 394 / 10

n = 39.4

Since we cannot sell a fraction of a necklace, Bret would need to make and sell 40 necklaces to break even.

The total expenses for 40 necklaces would be $394 * 40 = $15,760, and the total sales would be $10 * 40 = $400.

Alex is making a rectangular garden and wants a fence around it. He wants the length of the garden to be 3 feet longer than the width. 150 feet of fence is all he can afford. What is the greatest possible width he can have for his garden?

Answers

Since it's rectangular, there is a length and width. Let the width be w, and the length is then w+3. The total length of the fence is the perimeter, so 150 = 2*w + 2*(w+3) = 4w+6. Solving for w, this becomes w=(150-6)/4 = 144/4 = 36 feet.

The random variable X ≈ B(n, p)

Where n is the number of samples. If the value of n is huge, calculating binomial coefficient can be difficult and calculator won't be able to perform the nCr calculation for a big value of n (try ⁶⁰⁰C₁₂₃ on the calculator).

If p, which is the probability, is close to 0.5, the binomial distribution will be fairly symmetric.

We have n = 114 and p = 22% = 0.22

We first need to approximate X by Y ≈ N(np, np(p-1))

np = 114×0.22 = 25.08
np(1-p) = 114×0.22×0.78 = 19.6

Therefore, Y ≈ N(25.08, 19.6)
and since the standard deviation, б = √np(1-p) = √19.6
We then have, Y≈N(25.08, (√19.6)²)

We aim to find the probability of X is exactly 27, mathematically written as P(X=27)

Applying the continuity correction we have P(26.5<Y<27.5) ⇒ This correction, in other words, is applying a range to X that will definitely include the value of X=27

The next step is standardising
We have the mean, μ=25.08 and σ=√19.6

P(26.5<Y<27.5) = P([tex] \frac{26.5-25.08}{ \sqrt{19.6} } [/tex]<Z<[tex] \frac{27.5-25.08}{ \sqrt{19.6} } [/tex])
P(26.5<Y<27.5) = P(0.32<Z<0.55)
P(26.5<Y<27.5) = P(Z<0.55) - [1 - P(Z<0.32)] ⇒ Read the values for these z-score on the z-table
P(26.5<Y<27.5) = 0.7088 - [1-0.6255]
P(26.5<Y<27.5) = 0.3343

A house is advertised as having 1 420 square feet under roof. what is the area of this house in square meters? (a) 115 m 2

Answers

Final answer:

To convert square feet to square meters, we multiply the number of square feet (1,420) by the conversion factor (0.092903), resulting in approximately 132 square meters as the area of the house.

Explanation:

To convert the area of a house from square feet to square meters, we use the conversion factor where 1 square foot equals 0.092903 square meters. The house in question has 1,420 square feet, so we multiply this number by the conversion factor to find the area in square meters.a

1,420 square feet * 0.092903 square meters/square foot = 131.92186 square meters.

We can round the final result to the nearest whole number, which gives us approximately 132 square meters as the area of the house.

Answers

To solve this problem, let us first remember that the formula for rate is:

rate = f (n) = A (r)^(n-1)

Where,

A = the 1st term

r = fractional rate of evaporation

n = number of terms

Now let us calculate for the fraction rate of evaporation, r. Since it is stated that the evaporation is happening at a fixed rate, therefore we can use any two given f (n) values to find for r. In this case, let us use when n=1 and 2.

r = 27 / 54

r = 0.5

The first term in the series is when n = 1 and that is:

A = 54

Therefore substituting all known values to the equation:

What is the discriminant of 3x2-10x=-2 ?

Answers

The discriminant of [tex]3x^2-10x=-2[/tex] is 76

To find the discriminant of [tex]3x^2-10x=-2[/tex], we have to recall the quadratic formula.

Further Explanation

The formula of the quadratic equation can be expressed as [tex]ax^2+bx+c=0[/tex] and discriminant also expressed as [tex]D=b^2-4ac[/tex]

Using the quadratic formula, the given question can be expressed as:

[tex]3x^2-10x+2=0[/tex]

Where a = 3, b = -10, and c = 2

If we substitute the values, then the discriminant would be:

Recall the discriminant is [tex]D=b^2-4ac[/tex]

Therefore, we have

[tex]D=(-10)^2-4(3)(2)[/tex]

[tex]D=100-24[/tex]

[tex]D=76[/tex]

Thus, the discriminant of [tex]3x^2-10x=-2[/tex] is 76.

Discriminant is very helpful in quadratic equation as it helps reveals the number of real solutions to a given quadratic equation. In other words, it helps you to solve quadratic equation.

While discriminant only tells only reveals the number of real solutions, it doesn’t reveal what the solutions are. The determinant would only give you hint as regards the number of real solution to look for.

Choose the graph below that correctly represents the equation 15x − 5y = 30.

PLEASE HELP!!!

Answers

You didn't give us a picture but I'll help you as best as I can.

First, convert the equation into the form y=mx+b:
15x-5y=30
-5y=-15x+30

Divide both sides by -5.
y=-3x-6

Below is a graph of that equation:

Final answer:

To choose the correct graph that represents the equation 15x - 5y = 30, isolate y, find the slope and y-intercept, and compare to the given graphs.

Explanation:

In order to choose the correct graph that represents the equation 15x - 5y = 30, we need to solve the equation for y.

First, let's isolate y by subtracting 15x from both sides of the equation:

15x - 5y - 15x = 30 - 15x

-5y = -15x + 30

Next, divide both sides of the equation by -5 to find the value of y:

-5y/-5 = (-15x + 30)/-5

y = 3x - 6

Now that we have the equation in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we can determine the graph that represents the equation. The slope of the equation is 3, which means that for every 1 unit increase in x, y increases by 3 units. The y-intercept is -6, which means that the graph intersects the y-axis at the point (0, -6).

Based on this information, we can determine that the graph that correctly represents the equation 15x - 5y = 30 is the one where the slope is 3 and it intersects the y-axis at (0, -6).

What positive number is the same as its reciprocal?

Answers

1 It's the only positive number whose reciprocal is its equal

Final answer:

The only positive number that is the same as its reciprocal is 1. This is achieved by setting up the equation x = 1/x and solving it.

Explanation:

In mathematics, a number and its reciprocal are the same when the number is 1. If you denote the mysterious number we are looking for as 'x', then its reciprocal would be 1/x. Since the number and its reciprocal are the same, we can set up the equation x = 1/x. Solving this equation, we cross multiply to get x^2 = 1. The positive solution to this equation is x = 1, which confirms that the only positive number that is the same as its reciprocal is 1.
