Mandy makes beaded bracelets and sells them for $5 each. If she sells the bracelets for 250% of the cost of her materials, how much does each bracelet cost to make?

Each bracelet costs $
to make.

Answer:

2 1/3 ssssssssssssddddss

Answer:

You would need 3 to make 1 whole cup

Step-by-step explanation:

Because If we look at it fraction wise

It would be 1/3 right ? and all we need is to make a whole so if we get 3 of 1/3 cups it would be 3/3 . Which equals to 1 cup

Answer:

(a) 2000 mL

(b) 70 mL, 30 mL

(c) No

Step-by-step explanation:

Given that Artesia is a 70% acid solution, and Borromeo is a 20% acid solution.

(a) Let x mL of Artesia is added to 500  mL of Borromeo to produce a 60% acid solution.

So, 70% of x + 20% of 500 = 60% of (x+500)

[tex]\Rightarrow 0.7 \times x + 0.2 \times 500 = 0.6 \times (x+500) \\\\\ \Rightarrow 0.7 \times x + 0.2 \times 500 = 0.6 \times x+0.6 \times500\\\\ \Rightarrow 0.7 \times x -0.6 \times x= 0.6 \times500- 0.2 \times 500 \\\\ \Rightarrow (0.7-0.6) \times x = (0.6-0.2) \times500\\\\\Rightarrow 0.1 \times x = 0.4 \times500\\\\[/tex]

[tex]\Rightarrow x = (0.4 \times500)/0.1=2000[/tex] mL.

(b) Let x mL of Artesia and y mL be combined in order to form a 100 mL solution having 55% acid solution.

So, x+y=100\Rightarrow y= 100-x

And, 70% of x + 20% of y = 55% of (100)\\\\

[tex]\Rightarrow 0.7 \times x + 0.2 \times (100-x) = 0.55 \times 100\\\\\Rightarrow 0.7 \times x + 0.2 \times 100- 0.2 \times x = 0.55 \times 100\\\\\Rightarrow 0.7 \times x -0.2 \times x= 0.55 \times100- 0.2 \times 100 \\\\\Rightarrow (0.7-0.2) \times x = (0.55-0.2) \times100\\\\\Rightarrow 0.5 \times x = 0.35 \times100\\\\[/tex]

[tex]\Rightarrow x = (0.35 \times100)/0.5=70[/tex] mL.

and y= 100-x= 100-70=30 mL.

(c)  Let x mL of Artesia and y mL of Borromeo be combined in order to make 80% acid solution.

And, 70% of x + 20% of y = 80% of (x+y)

[tex]\Rightarrow 0.7 \times x + 0.2 \times y= 0.8 \times (x+y)\\\\\Rightarrow 0.7 \times x + 0.2 \times y = 0.8 \times x +0.8 \times y\\\\\Rightarrow (0.7-0.8) \times x = (0.8-0.2) \times y\\\\\Rightarrow -0.1 \times x = 0.6 \times y \\\\\Rightarrow \frac {x}{y} = -6 \\\\[/tex]

As x and y are amount of Artesia and Borromeo, so x>0 and y>0

[tex]\Rightarrow x/y >0[/tex], so the negative value of x/y is not possible.

Ad the negative value of x/y is not so x/y=-6 is not possible, hence,  any combination of Artesia and Borromeo that is 80% acid solution is not possible.

General Formulas and Concepts:

Step-by-step explanation:

Step 1: Define expression

-2y + 10 + 2y - 8

Step 2: Simplify

Answer:

Step-by-step explanation:

-2y + 10 + 2y - 8 = 20 - 8 = 2

I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following

a^2 + b^2 = c^2

16^2 + 20^2 = c^2

256 + 400 = c^2

656 = c^2

c^2 = 656

c = sqrt(656)

c = sqrt(16*41)

c = sqrt(16)*sqrt(41)

c = 4*sqrt(41)

The hypotenuse is exactly 4*sqrt(41) units long

This is approximately 25.612 when you use your calculator.

Answer: , y = 65+25x

Step-by-step explanation:

Let x = Number of charms

Given : Fixed cost of bracelet = $65

On addition , cost per charm = $25

Total cost of bracelet = Fixed charge + (Charge per charm)  x (number of charm)

If y= total cost.

Then, y = 65+25x , which is the required equation.

Answer:

There is no maximum. The minimum is (-1,-4). The shape is a parabola. Yes it is a function. It is continuous. The line of symmetry is x=1 I believe. The x intercepts are x=1 and x=-3. The y-intercept is y=3. It opens up

Answer:

B...i'm pretty sure that this Is the right one

Answer:

The x-intercept is 4,0. The y-intercept is 0,2.

Step-by-step explanation:

when your finding an intercept you make the other intercept 0. This means the equation to find the x-intercept would look like 5x = 20. This is because they = 0, which means 10 x 0 is 0. Then you use the inverse operation so since it's 5 * x, it will be 20 ÷ 5 which is 4. Do the same thing with the y-intercept. Instead of changing the y to a 0, change the x. Using the inverse operation you get 2.

Answer:

The first term would be 18 ig, and then the common differnce would be 7.

Step-by-step explanation:

The rule to the sequence is that they are adding by 7 every term.

Answer:

x=3

Step-by-step explanation:

3x-4=8-x(Group like terms)

3x+x=8+4(Add both sides)

4x=12(After adding you will proceed to divide both sides by 4)

x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)

Answer:

$1015

Step-by-step explanation:

280 divided by 2 140 times $7.25 is $1015

The amount of money that the store lose by giving away the free tubes of paint is $1015.

Since the manager held Buy 2, Get 1 Free sale on tubes of watercolor paints, then when 280 tubes of paints are sold, 1/2 × 280 = 140 tubes of paints will be given out for free.

Therefore, the amount lost will be calculated by multiplying the number of paints given out by the price. This will be:

= 140 × $7.25

= $1015

Therefore, the amount of money that the store lose by giving away the free tubes of paint is $1015.
