A jewelry store marks up the price of bracelets they purchase at $30.00 each by 75%. What is the markup and new price of each bracelet?

Answer:

You start the shelf 4 ft. 9 in. from the wall.

Step-by-step explanation:

The game plan is to take the length of the shelf away from the length of the wall, and then divide the remaining part into two equal pieces.

13 ft.

-  3 ft. 6 in.

12 ft  12 in,

- 3ft    6 in

9 ft   6 in.

9 ft. 6 inches divided by 2 equals 4.5 ft, 3 in.

.5 ft * 12 inches = 6 inches

You start the shelf 4 ft. 9 in. from the wall.

The length from the corner for the edge of a 3ft 6in shelf for it to be centered on the wall is A = 4.75 feet = 4 feet 9 inches

The diagonal of a rectangle is calculated by the formula

From the Pythagoras Theorem , The hypotenuse² = base² + height² , and

Diagonal of a Rectangle = √ ( Length )² + ( Width )²

Given data ,

To center a shelf on a 13-foot long wall, we need to find the midpoint of the wall, and then subtract half the length of the shelf to determine the position of the shelf's edge.

First, we need to convert 3 feet 6 inches to feet. There are 12 inches in a foot, so:

3 feet 6 inches = 3 + 6/12 = 3.5 feet

Now , the diagonal of the rectangular shelf is

The midpoint of the wall is half of 13 feet, which is:

13 / 2 = 6.5 feet

To find the distance from the corner to the edge of the shelf, we need to subtract half the length of the shelf from the midpoint of the wall:

6.5 feet - 1.75 feet = 4.75 feet

Hence , the shelf should be placed 4.75 feet from the corner to be centered on the 13-foot long wall.

$5.10 For the 2 extra panes

Step-by-step explanation:

So 9 pained are 22.95

22.95/9=2.55

Since 2 panes are broken

2.55*2

that is 5.1

or $5.10

Answer:

$5.20

Step-by-step explanation:

First, we need to work out how much 1 pane is.

So $22.95÷9=$2.55

Then you times it by 2

So $2.55×2=$5.20

Answer:

0.61596

Step-by-step explanation:

Given that:

λ = 5 (5 errors per page)

Poisson distribution formula :

P(x = x) = (λ^x * e^-λ) / x!

Probability that page does not need to be retyped means that error on page is less than or equal to 5

P(x ≤ 5) = p(x = 5) + p(x = 4) +... + p(x = 0)

The individual probabilities can be obtained using the formula above or the use of a calculator

P(x ≤ 5) = 0.17547 + 0.17547 + 0.14037 + 0.08422 + 0.03369 + 0.00674

P(x ≤ 5) = 0.61596

Step-by-step explanation:

To convert square miles to square feet, multiply the square mile value by 27878400. For example, to convert 10 square miles to square feet, multiply 10 by 27878400, that makes 278784000 sq ft is 10 sq mi.

Answer:

1213 tablespoons

1 teaspoon

Step-by-step explanation:

This answer is my interpretation of what the question is asking, it could be wrong.

This question says, one has 2426 tablespoons, and 2 teaspoons of a substance. If one were divided that quantity in half, how much of that substance could they have. So essentially, all one needs to do is divided 2426 by 2, and divide 2 by 2.

2426 ÷ 2 = 1213

2 ÷ 2 = 1

Step-by-step explanation:

I calculated logically

Given:

Sum of the radius of the base and height of a cylinder = 21 cm

Curved surface area of the cylinder = 616 sq.cm

To find:

The total surface area of the cylinder.

Solution:

Let r be the radius of the base and h be the height of the cylinder.

Sum of the radius of the base and height of a cylinder = 21 cm

[tex]r+h=21[/tex]

[tex]h=21-r[/tex]           ...(i)

Curved surface area of the cylinder is

[tex]CSA=2\pi rh[/tex]

Curved surface area of the cylinder = 616 sq.cm

[tex]2\pi rh=616[/tex]

[tex]2(\dfrac{22}{7})r(21-r)=616[/tex]

[tex]44r(21-r)=616\times 7[/tex]

[tex]21r-r^2=\dfrac{616\times 7}{44}[/tex]

[tex]21r-r^2=14\times 7[/tex]

[tex]0=98-21r+r^2[/tex]

[tex]0=98-14r-7r+r^2[/tex]

[tex]0=14(7-r)-r(7-r)[/tex]

[tex]0=(7-r)(14-r)[/tex]

[tex]r=7,14[/tex]

Using (i), for r=7, h=14 and for r=14, h=7.

Total surface area of the cylinder is

[tex]A=2\pi r(r+h)[/tex]

For r=7 and h=14,

[tex]A=2(\dfrac{22}{7})(7)(7+14)[/tex]

[tex]A=44(21)[/tex]

[tex]A=924[/tex]

For r=14 and h=7,

[tex]A=2(\dfrac{22}{7})(14)(14+7)[/tex]

[tex]A=88(21)[/tex]

[tex]A=1848[/tex]

Therefore, the total surface area of the cylinder is either 924 sq.cm or 1848 sq. cm.

Answer:

Cost of four DVD= 36.7, but due to 25% discount it cost 27.57. Then add 7.75 taxes and he payed 29.71. Answer is 29.71

Step-by-step explanation:

Answer:

$27.71

Step-by-step explanation:

Price of 1 DVD: $9.19

Price of 4 DVDs: 4 * $9.19 = $36.76

Discount: 25%

Now we find 25% of $36.76.

25% of $36.76 =

= 0.25 * $36.76

= $9.19

The 25% discount amounts to $9.19. We now subtract $9.19 from $36.76 to find the discounted price.

$36.76 - $9.19 = $27.57

Now we need to apply the 7.75% tax to $27.57.

7.75% of $27.57 =

= 0.0775 * $27.57

= $2.14

The sales tax is $2.14.

Now we add the sales tax amount to the total discounted price.

$27.57 + $2.14 = $29.71

Answer: $27.71
