The price of the advertisement that originally costs $110 after a 15% markdown is $ 83.5.

Original price = $110

Markdown percent = 15%

Reduce in price = 15% of 110

To calculate this, we divide the percent by 100 and multiply it by the number given. Like in the above case, we divide 15 by 100 to get 0.15 and multiply it by 110.

= 0.15 * 110 = 16.5

Price after markdown = original price - reduction in price

= 110 - 16.5

= $ 83.5

Thus, the price for a quarter-page ad of the school yearbook which used to be $110 has come down to $83.5 after a 15 % markdown to attract more sponsors.

The child can make 120 different bracelets using one of each charm. To solve this problem, we need to use a combinatorial approach.

The number of different bracelets that the child can make depends on the number of charms that can be used for each bracelet & the order in which they are arranged. Since each charm can be used only once, we have to choose five charms out of the total of five available charms, which can be done in 5C5 ways.

We can think of this problem as a permutation problem. There are five distinct charms, and we need to choose five of them to make a bracelet. The order in which we choose the charms matters, as each order gives us a different bracelet. Therefore, we need to use the formula for permutations.

The formula for permutations is given by:

nPr = n! / (n-r)!

where n is the total number of objects, and r is the number of objects we want to choose.

For this problem, n = 5 (since there are five distinct charms), and r = 5 (since we want to choose all five charms).

Plugging these values into the formula, we get:

5P5 = 5! / (5-5)! = 5! / 0! = 5 x 4 x 3 x 2 x 1 / 1 = 120

Therefore, the child can make 120 different bracelets.

Alternatively, we can also think of this problem as a multiplication principle problem. There are five distinct charms, & we need to choose one charm out of five for the first position, one charm out of four for the second position, one charm out of three for the third position, one charm out of two for the fourth position, & one charm out of one for the fifth position.

Using the multiplication principle, we can multiply these numbers together to get the total number of different bracelets:

5 x 4 x 3 x 2 x 1 = 120

Therefore, the child can make 120 different bracelets using one of each charm.

The probability of Henry choosing a Milky Way and then a Snickers is 2/27.

1. First, let's find the total number of candy pieces in Henry's candy jar:
3 Snickers + 1 Reese's + 1 Twix + 2 Milky Ways + 2 Skittles Packs = 9 pieces of candy.

2. Next, we'll calculate the probability of choosing a Milky Way on the first pick:
There are 2 Milky Ways and 9 total pieces of candy, so the probability is 2/9.

3. Since Henry puts the candy back, there are still 9 pieces of candy for the second pick. Now, we'll calculate the probability of choosing a Snickers on the second pick:
There are 3 Snickers and 9 total pieces of candy, so the probability is 3/9 (or 1/3).

4. Finally, we'll multiply the probabilities of each individual event to find the probability of both events occurring together (choosing a Milky Way and then a Snickers):
(2/9) * (1/3) = 2/27

Step-by-step explanation:

The interior angle measures at stages A, B, and C are approximately 71.7 degrees, 133.4 degrees, and 175.0 degrees, respectively. Therefore, the angles in descending order are C, B, and A.

Let's label the stages A, B, and C. To find the interior angles at each stage, we can use the Law of Cosines:

cos(A) = (b^2 + c^2 - a^2) / 2bc

cos(B) = (c^2 + a^2 - b^2) / 2ca

cos(C) = (a^2 + b^2 - c^2) / 2ab

where a, b, and c are the distances between the centers of the stages.

Using the given distances, we have:

a = 100, b = 135, c = 210

cos(A) = (135^2 + 210^2 - 100^2) / (2*135*210) ≈ 0.309

cos(B) = (210^2 + 100^2 - 135^2) / (2*210*100) ≈ -0.692

cos(C) = (100^2 + 135^2 - 210^2) / (2*100*135) ≈ -0.905

To find the interior angles, we can take the inverse cosine (also known as arccosine) of each value:

A ≈ 71.7 degrees

B ≈ 133.4 degrees

C ≈ 175.0 degrees

So the interior angle measures at stages A, B, and C are approximately 71.7 degrees, 133.4 degrees, and 175.0 degrees, respectively. Therefore, the angles in descending order are C, B, and A.

(a) The expressions for the length, width, and height can be 3x, (2x + 5), and (x - 3).

(b) The least possible integer value of x for the rectangular solid to exist is 4.

a. To express the length, width, and height of the right rectangular prism in terms of x, we can factor the volume expression, 6x³ - 3x² - 45x.

Factoring out the greatest common factor, 3x:

3x(2x² - x - 15)

Now, factor the quadratic expression:

3x(2x² - x - 15)

To factor the quadratic expression further, find two numbers whose product equals the constant term (-15) and whose sum equals the coefficient of the linear term (-1). These two numbers are -5 and 3.

3x(2x + 5)(x - 3)

Thus, the expressions for the length, width, and height can be 3x, (2x + 5), and (x - 3)

b. For the rectangular solid to exist, all dimensions (length, width, and height) must be positive. Let's examine the constraints on x for each dimension:

1. 3x > 0
2. 2x + 5 > 0 → x > -5/2

To find f'(-2), we need to first find the derivative of f(x) using the chain rule.

f'(x) = (1/(5x² + 20x + 1)) * (10x + 20)

Then, we can plug in x = -2 to get f'(-2):

f'(-2) = (1/(5(-2)² + 20(-2) + 1)) * (10(-2) + 20)

f'(-2) = (1/(20 - 40 + 1)) * (-20 + 20)

f'(-2) = 0

Therefore, f'(-2) is equal to 0.

To find f'(-2) for f(x) = ln(5x² + 20x + 1), we first need to find the derivative of f(x) using the chain rule. The chain rule states that the derivative of a composite function is the derivative of the outer function times the derivative of the inner function.

1. Let u = 5x² + 20x + 1. Then, f(x) = ln(u).
2. Find the derivative of f(x) with respect to u: f'(x) = d[ln(u)]/du = 1/u.
3. Find the derivative of u with respect to x: du/dx = d(5x² + 20x + 1)/dx = 10x + 20.
4. Apply the chain rule: f'(x) = (1/u) * (du/dx) = (1/(5x² + 20x + 1)) * (10x + 20).

Now, to find f'(-2), simply substitute -2 for x in the derivative:

f'(-2) = (1/(5(-2)² + 20(-2) + 1)) * (10(-2) + 20)
f'(-2) = (1/(20 - 40 + 1)) * (-20 + 20)
f'(-2) = (1/(-19)) * 0

a. The equation is Total Cost = 0.75x + $600

b. Total cost is $60,600 and net profit is $19,400.

c. The breakeven level of sales volume is $2,400.

a. The equation relating total cost and sales volume can be expressed as:

Total Cost = Cost of Goods Sold + Selling Expenses + Fixed Expenses

where Cost of Goods Sold = 60% (100% - 40%) of the sales volume

           Selling Expenses = 15% of the sales volume

           Fixed Expenses = $600.

Therefore, the equation can be written as:

Total Cost = 0.6x + 0.15x + $600
                 = 0.75x + $600

b. For sales of $80,000, we can substitute x = $80,000 into the equation:

Total Cost = 0.75x + $600
                 = 0.75($80,000) + $600
                 = $60,000 + $600
                 = $60,600

To calculate net profit before taxes, we need to subtract the total cost from the sales volume:

Net Profit before Taxes = Sales - Total Cost
                                       = $80,000 - $60,600
                                       = $19,400

c. To find the breakeven level of sales volume, we need to set the net profit before taxes to zero and solve for x:

Net Profit before Taxes = Sales - Total Cost
               0                      = x - (0.6x + 0.15x + $600)
               0                      = 0.25x - $600

The perpendicular distance between the bases of a trapezoid with an area of 337.5 ft² and base lengths of 25 ft and 20 ft is 15 ft.

Area = (1/2) * (Base1 + Base2) * Height

In this case, the area is 337.5 ft², Base1 is 25 ft, and Base2 is 20 ft. We need to solve for the height, which represents the perpendicular distance between the bases.

Plugging in the known values into the formula:

The length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm

Rhombus is a special type of parallelogram in which all four sides are congruent. The opposite angles of a rhombus are also congruent, and the diagonals bisect each other at right angles.

Now, let's consider the given rhombus abcd, where ad = 8cm and m∠ade=20°. We need to determine the length of diagonals ac and bd.

First, let's use the law of cosines to find the length of side ae. We know that ad = 8cm, and m∠ade=20°, so we can use the formula:

ae² = ad² + de² - 2ad(de)cos(m∠ade)

Substituting the values, we get:

ae² = 8² + de² - 2(8)(de)cos(20°)

Next, we can use the fact that a rhombus has all sides congruent to find the length of side de. Since abcd is a rhombus, we know that ac and bd are also congruent diagonals that bisect each other at right angles. Therefore, we can draw diagonal ac and use the Pythagorean theorem to find the length of ac:

ac² = (ae/2)² + (de/2)²

Substituting ae² from the previous equation, we get:

ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²

Simplifying the equation and using the fact that ac and bd are congruent, we get:

bd² = ac² = (8² + de² - 2(8)(de)cos(20°))/2

Finally, we can use the Pythagorean theorem to find the length of diagonal bd:

bd² = ab² + ad²

Substituting ab = ac/2 and ad = 8cm, we get:

bd² = (ac/2)² + 8²

Substituting ac² from the previous equation, we get:

bd² = ((8² + de² - 2(8)(de)cos(20°))/8)² + 8²

Simplifying the equation, we get:

bd ≈ 12.22 cm

Similarly, we can solve for ac using the equation we derived earlier:

ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²

Substituting de ≈ 9.84cm (which we can solve for from the equation ae² = 8² + de² - 2ad(de)cos(m∠ade)), we get:

ac ≈ 15.58 cm

Therefore, the length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm
