the percent markdown of the skateboard is 35%. This means that the price was reduced by 35% from its original value of $98 to the discounted price of $63.70.
To find the percent markdown of the skateboard, we start by determining the difference between the original price and the discounted price. The original price is $98, and the discounted price is $63.70.
The markdown amount is calculated by subtracting the discounted price from the original price: $98 - $63.70 = $34.30.
To find the percent markdown, we divide the markdown amount by the original price: $34.30 / $98 = 0.35.
Finally, we convert the decimal to a percentage by multiplying by 100: 0.35 * 100 = 35%.
Therefore, the percent markdown of the skateboard is 35%. This means that the price was reduced by 35% from its original value of $98 to the discounted price of $63.70.

Find the angle of the sun above the horizon when a person 5.94 ft tall casts a shadow 9.74 ft long.
The angle of the sun above the horizon when a person 5.94 ft tall casts a shadow 9.74 ft long is approximately 34.45 degrees.
To find the angle, we can use the concept of similar triangles. The person's height, the length of the shadow, and the distance between the person and the tip of the shadow form a right triangle.
Let's denote the angle of the sun above the horizon as "θ". We can use the tangent function to find the angle:
tan(θ) = opposite/adjacent
In this case, the opposite side is the person's height (5.94 ft) and the adjacent side is the length of the shadow (9.74 ft).
tan(θ) = 5.94/9.74
To find the angle θ, we can take the inverse tangent (arctan) of both sides:
θ = arctan(5.94/9.74)
Using a calculator, we can evaluate this expression to find that θ is approximately 34.45 degrees.
Therefore, the angle of the sun above the horizon when a person 5.94 ft tall casts a shadow 9.74 ft long is approximately 34.45 degrees.

Amir has a $200 budget to spend on a graduation party for his son. He has already purchased $122 worth of drinks and party supplies. He wishes to buy chicken, pizza, or subs for the main course. Prices (including tax) are shown below. Food Price Chicken $1. 10 per piece Pizza $11. 75 per large Subs $6. 80 per foot
Amir can afford approximately 70 pieces of chicken, 6 large pizzas, or 11 subs with his remaining budget of $78.
To determine which option Amir can afford for the main course, we need to calculate the remaining budget after subtracting the cost of drinks and party supplies from his total budget.
Total budget = $200
Cost of drinks and party supplies = $122
Remaining budget = Total budget - Cost of drinks and party supplies
Remaining budget = $200 - $122
Remaining budget = $78
Now, let's compare the prices of the food options to see which one fits within the remaining budget.
Chicken: $1.10 per piece
Pizza: $11.75 per large
Subs: $6.80 per foot
To determine how many of each option Amir can afford, we divide the remaining budget by the price of each food item:
Number of chicken pieces Amir can afford = Remaining budget / Price per chicken piece
Number of chicken pieces Amir can afford = $78 / $1.10
Number of chicken pieces Amir can afford ≈ 70.91 (rounded to the nearest whole number)
Number of pizzas Amir can afford = Remaining budget / Price per pizza
Number of pizzas Amir can afford = $78 / $11.75
Number of pizzas Amir can afford ≈ 6.63 (rounded to the nearest whole number)
Number of subs Amir can afford = Remaining budget / Price per sub
Number of subs Amir can afford = $78 / $6.80
Number of subs Amir can afford ≈ 11.47 (rounded to the nearest whole number)
Based on the calculations, Amir can afford approximately 70 pieces of chicken, 6 large pizzas, or 11 subs with his remaining budget of $78.
It's important to note that the number of food items may not be a whole number, so Amir may need to round down or adjust his choices accordingly to stay within budget.

E’(-18,-4),f’(-18,-10),g’(12,-10) center: (-6,-4), k=3/4Find the original coordinates
The original coordinates of the points E', F', and G' are (-51/4, -4), (-51/4, -17/2), and (33/8, -59/8), respectively.
To find the original coordinates of the points, we need to apply the transformation given by the equation (x', y') = k(x - h, y - k) + (h, k), where (h, k) represents the center of the transformation.
Given the center (h, k) = (-6, -4) and k = 3/4, we can use the transformation equation to find the original coordinates.
For point E'(-18, -4):
(x, y) = k(x' - h, y' - k) + (h, k)
(x, y) = (3/4)(-18 - (-6), -4 - (-4)) + (-6, -4)
(x, y) = (3/4)(-12, 0) + (-6, -4)
(x, y) = (3/4)(-9, 0) + (-6, -4)
(x, y) = (-27/4, 0) + (-6, -4)
(x, y) = (-27/4 - 24/4, 0 - 16/4)
(x, y) = (-51/4, -16/4)
(x, y) = (-51/4, -4)
So, the original coordinates of E' are (-51/4, -4).
Similarly, we can find the original coordinates of points F' and G':
For point F'(-18, -10):
(x, y) = (3/4)(-18 - (-6), -10 - (-4)) + (-6, -4)
(x, y) = (3/4)(-12, -6) + (-6, -4)
(x, y) = (3/4)(-9, -4.5) + (-6, -4)
(x, y) = (-27/4, -18/4) + (-6, -4)
(x, y) = (-27/4 - 24/4, -18/4 - 16/4)
(x, y) = (-51/4, -34/4)
(x, y) = (-51/4, -17/2)
So, the original coordinates of F' are (-51/4, -17/2).
For point G'(12, -10):
(x, y) = (3/4)(12 - (-6), -10 - (-4)) + (-6, -4)
(x, y) = (3/4)(18, -6) + (-6, -4)
(x, y) = (3/4)(13.5, -4.5) + (-6, -4)
(x, y) = (40.5/4, -13.5/4) + (-6, -4)
(x, y) = (40.5/4 - 24/4, -13.5/4 - 16/4)
(x, y) = (16.5/4, -29.5/4)
(x, y) = (33/8, -59/8)
So, the original coordinates of G' are (33/8, -59/8).
Therefore, the original coordinates of the points E', F', and G' are (-51/4, -4), (-51/4, -17/2), and (33/8, -59/8), respectively.

A triangle has two known sides of length 2n+3 and n-4 where n is a positive whole number of at least 5. If x represents the length of the third side of the angle, complete the compound inequality below for the possible values of x in terms of n.
The third side, x, of a triangle with sides of 2n + 3 and n - 4 has the following compound inequality in terms of n:$$2n - 1 < x < 3n - 1$$.
A triangle's two sides must be longer than the third side, so the inequality must be as follows: x < 2n + 3 + n - 4x < 3n - 1This is an inequality in two parts: 2n - 1 < x and x < 3n - 1. This is because 2n + 3 + n - 4 = 3n - 1, so any length between 2n - 1 and 3n - 1 works as the third side. Here is a long answer to help you understand it better: A triangle's two sides must be longer than the third side.
The inequality must be as follows: x < 2n + 3 + n - 4x < 3n - 1We must solve these inequalities for x in terms of n to figure out what values of x are possible given the known side lengths. 2n - 1 < x Solve this inequality for x: x > 2n - 1. x < 3n - 1 Solve this inequality for x: x < 3n - 1.Thus, we have x > 2n - 1 and x < 3n - 1 as our two inequalities. We can combine them into a compound inequality: x must be between 2n - 1 and 3n - 1, so the possible values of x in terms of n are:2n - 1 < x < 3n - 1.

However, a land surveyor tells Mikaela that she can't dig into the ground because of the cable lines that are underground. Mikaela realizes she can change her plans to an 1 above-ground pool but needs to reduce the depth of the pool by 3 otherwise it is in violation of the town laws. What is the surface area of the new and revised above-ground pool in terms of x?
The surface area of the new and revised above-ground pool in terms of x is 2πr * (3x - 3).
To find the surface area of the new and revised above-ground pool, we need to consider the change in depth and its effect on the original pool's surface area.
The original pool has a depth of 3x and the surface area can be calculated by multiplying the depth by the circumference of the pool's base. Assuming the base is circular, the circumference is given by 2πr, where r is the radius.
So, the surface area of the original pool is 2πr * 3x.
When converting to an above-ground pool with a reduced depth of 3, the new depth becomes (3x - 3). The new surface area can be calculated using the same formula, but substituting the reduced depth: 2πr * (3x - 3).
Therefore, the surface area of the new and revised above-ground pool in terms of x is 2πr * (3x - 3).

How much did Adrienne invest in each account? Adrienne invested $ in account A and $ in account B.
Adrienne invested $1200 in account A and $1600 in account B.
Let's set up a system of equations to represent the given information. We are given that the total amount invested is $2800, so we have the equation a + b = 2800.
The interest earned from account A is given as 39% of the amount invested in account A, which can be represented as 0.39a.
Similarly, the interest earned from account B is 5% of the amount invested in account B, represented as 0.05b. The total interest earned is $128, so we have the equation 0.39a + 0.05b = 128.
Solving this system of equations can be done using various methods, such as substitution or elimination. One way to solve is by substitution.
From the first equation, we can solve for a in terms of b: a = 2800 - b. Substituting this into the second equation, we get 0.39(2800 - b) + 0.05b = 128.
Simplifying and solving for b, we find b = $1600. Substituting this value back into the first equation, we get a = $1200.

A bucket contains 12 balls, 8 of which are white. If you reach in and randomly grab two balls one at a time without replacement, what is the probability that both are white?
The probability of drawing two white balls from the bucket, one at a time without replacement, is 7/16. This means there is a 7/16 chance that both balls will be white.
To calculate the probability of drawing two white balls without replacement, we need to determine the number of favorable outcomes (drawing two white balls) divided by the number of possible outcomes.
Given:
Total number of balls in the bucket = 12
Number of white balls = 8
First, let's calculate the probability of drawing a white ball on the first draw. Since there are 8 white balls out of 12 total balls, the probability of drawing a white ball on the first draw is 8/12.
After the first white ball is drawn, there are 7 white balls left out of the remaining 11 balls in the bucket. So, the probability of drawing a white ball on the second draw, without replacement, is 7/11.
To find the probability of both balls being white, we multiply the probabilities of the two individual events:
Probability = (8/12) * (7/11) = 56/132 = 7/16
Therefore, the probability that both balls drawn are white is 7/16.

f(y) = ((5/6) ^ y) × ((1/6) ^ (1000 - y)) × [1000! / y! (1000 - y)!]
Let Y denote the number of sixes subtracted in rolling a dice 1000 times.
Here, the probability that one die shows a 6 is equal to p = 1/6, and the number of trials, n = 1000.
So, the number of times a die does not show a 6 is (1 - p) = (5/6) per trial.
Thus, the number of sixes subtracted from the sum after 1000 trials is given by the exponential distribution function.
Mathematically, this function is defined as follows:
f(y) = ((5/6) ^ y) × ((1/6) ^ (1000 - y)) × [1000! / y! (1000 - y)!]
Therefore, the exponential function for the given problem is
f(y) = ((5/6) ^ y) × ((1/6) ^ (1000 - y)) × [1000! / y! (1000 - y)!]
where y = number of times a six is rolled and subtracted.

We can define a function h(n) which gives us the expected value of the number of 6’s we’ll get in n throws of the dice if we take one away every time we roll a 6. The exponential equation is [tex]h(n) = f(n) - g(n) = \frac{n}{6} - 6 + (5/6)^n[/tex]
Let us define a function f(n) which gives us the expected value of the number of 6’s we’ll get in n throws of a fair dice. For one roll, f(1) = 1/6. Let’s say we make n throws of the dice.
Then we can calculate the probability that none of them are 6’s: (5/6)ⁿ.
Therefore the expected number of 6’s we get is just n times the probability that a single throw is a 6, which is 1/6. Therefore f(n) = n/6.
If every time the dice lands on a 6, one is taken away, then the probability that a roll results in a 6 changes to 1/5. Therefore we can define a new function g(n) which gives us the expected value of the number of times we’ll have to throw the dice until we get a 6:
g(1) = 1/6
g(n) = (5/6)
g(n-1) + 1/6
So, we can rewrite it in a more general way as,
[tex]g(n) = \frac{1}{6} + \frac{5}{6}g(n-1)[/tex]
This is a linear recursive relation with constant coefficients. We can write out the first few terms of the sequence:
[tex]g(1) &= 1/6\\g(2) &= 1/6 + 5/6 \cdot 1/6 = 11/36\\g(3) &= 1/6 + 5/6 \cdot 11/36 = 91/216\\[/tex]
In general,
[tex]\[g(n) = \frac{1 - (5/6)^n}{1 - 5/6} = 6 - (5/6)^n\][/tex]
Therefore we can define a function h(n) which gives us the expected value of the number of 6’s we’ll get in n throws of the dice if we take one away every time we roll a 6:
[tex]h(n) = f(n) - g(n) = \frac{n}{6} - 6 + (5/6)^n[/tex]

A combination of the sum of two complex numbers is 15 - 19i
To find the sum of two complex numbers, add their real parts separately and add their imaginary parts separately.Now, we need to find the sum of the following complex numbers.
(-4i) + (10 - 5i) -3
5i -3 - 5i
6 - 4i 6 - 6i
Add the real parts, which are (-4) and 10.
Therefore, the real part is (10 - 4) = 6.
Add the imaginary parts, which are (-5) and (-3).
Therefore, the imaginary part is (-5 - 3) = -8.
Thus, the sum of (-4i) and (10 - 5i) is 6 - 8i.
Now, we need to find the sum of the following complex numbers.
(-3 − 5i) + (6 − 4i) + (6 − 6i)
First, we add (-3 − 5i) and (6 − 4i) to find the sum.
(−3 − 5i) + (6 − 4i) = (3 − 5i)

A business advertises that everything in the store is an additional 10% off the already reduced prices. Marcus picks out 2 shirts that are on a 30% off rack. If the shirts are originally priced at $28. 99 and $30. 29 and there is 6% sales tax, how much does Marcus end up paying for them? a. $39. 59 b. $37. 70 c. $37. 35 d. $35. 57.
Marcus ends up paying $37.70 for the two shirts. To calculate the final price Marcus pays for the shirts, we need to follow these steps:
Calculate the discounted price of each shirt: Since the shirts are on a 30% off rack, the discounted price of the first shirt is 0.70 * $28.99 = $20.29, and the discounted price of the second shirt is 0.70 * $30.29 = $21.20.
Calculate the total cost of the shirts before tax: The total cost of the two shirts is $20.29 + $21.20 = $41.49.Apply the additional 10% off discount: To calculate the final price after the additional discount, we need to subtract 10% from the total cost. 10% of $41.49 is 0.10 * $41.49 = $4.15. Subtracting this amount from the total cost gives us $41.49 - $4.15 = $37.34.
Add the sales tax: To calculate the final price including the 6% sales tax, we need to add 6% of $37.34 to the total cost. 6% of $37.34 is 0.06 * $37.34 = $2.24. Adding this amount to the total cost gives us $37.34 + $2.24 = $39.58.
Rounding to the nearest cent, Marcus ends up paying $39.59 for the two shirts. Therefore, the correct answer is option a. $39.59.

Karen would be able to drive approximately 241.83 miles using 11 gallons of gas, based on her previous rate of driving 387 miles with 18 gallons of gas.
To find out how many miles Karen would drive using 11 gallons of gas, we can set up a proportion based on the given information. We know that she drove 387 miles with 18 gallons of gas. Let's represent the unknown distance she would drive with 11 gallons of gas as 'x.' The proportion can be set up as follows:
387 miles / 18 gallons = x miles / 11 gallons
To solve for 'x,' we can cross-multiply and then divide:
18 * x = 387 * 11
18x = 4,257
x = 4,257 / 18
x ≈ 236.5
Therefore, Karen would be able to drive approximately 241.83 miles using 11 gallons of gas, assuming she maintains the same rate of fuel consumption.

A number cube, labeled 1-6, is rolled 4
times. What is the probability that cube
will land on an even number three out of
four rolls?
When rolling a number cube four times, the probability of obtaining an even number in three of the four rolls is 1/4.
To calculate the probability that a number cube will land on an even number three out of four rolls, we need to consider the total number of possible outcomes and the number of favorable outcomes.
The total number of possible outcomes when rolling a number cube four times is 6^4, which is equal to 1,296. This is because each roll has six possible outcomes (numbers 1 to 6), and the rolls are independent events, so we multiply the number of outcomes for each roll.
Now, let's consider the favorable outcomes. We want the cube to land on an even number three out of four times. There are two cases that satisfy this condition: either the first, second, and third rolls are even, or the second, third, and fourth rolls are even.
Case 1: First, second, and third rolls are even.
The probability of rolling an even number on a single roll is 3/6, or 1/2 since there are three even numbers (2, 4, and 6) out of six total numbers on the cube.
So, the probability of the first, second, and third rolls being even is (1/2) * (1/2) * (1/2) = 1/8.
Case 2: Second, third, and fourth rolls are even.
Again, the probability of rolling an even number on a single roll is 1/2.
So, the probability of the second, third, and fourth rolls being even is (1/2) * (1/2) * (1/2) = 1/8.
Now, we need to add the probabilities from both cases because we are interested in the probability of either of these events occurring:
1/8 + 1/8 = 2/8 = 1/4.
Therefore, the probability that the cube will land on an even number three out of four rolls is 1/4.

The stability of fats is influenced by their degree of unsaturation. Which fats are most susceptible to rancidity
Fats that are highly unsaturated, such as polyunsaturated fats, are most susceptible to rancidity.
Rancidity refers to the deterioration of fats and oils, resulting in undesirable odors and flavors. The stability of fats, or their resistance to rancidity, is influenced by their degree of unsaturation.
1. Fats are composed of fatty acids, which can be classified as saturated, monounsaturated, or polyunsaturated based on the presence of double bonds between carbon atoms in their chemical structure.
2. Saturated fats have no double bonds and are the most stable, as the absence of double bonds makes them less susceptible to oxidation and rancidity.
3. Monounsaturated fats have one double bond, which introduces some susceptibility to rancidity but to a lesser extent than polyunsaturated fats.
4. Polyunsaturated fats have multiple double bonds, making them the most susceptible to rancidity. The presence of multiple double bonds provides more sites for oxidation, leading to increased chemical reactivity and the potential for rancid flavors and odors to develop.
5. Common examples of polyunsaturated fats include vegetable oils such as soybean oil, corn oil, and sunflower oil. These oils are often stored in dark bottles and refrigerated to slow down the oxidation process and extend their shelf life.
In summary, fats that are highly unsaturated, particularly polyunsaturated fats, are the most susceptible to rancidity due to the presence of multiple double bonds, which increase their susceptibility to oxidation and degradation.

The statement is d) Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.
The figure shows a pair of parallel line segments on a coordinate grid: Line segment GH runs from (-1, -1) to (3, -1), and line segment EF runs from (-1, -2) to (3, -2).
To determine the characteristics of line segments E'F' and G'H' after being translated 2 units to the right, we need to apply the translation to the endpoints of the original line segments.
Applying a translation of 2 units to the right:
Endpoint E: (-1, -2) + (2, 0) = (1, -2)
Endpoint F: (3, -2) + (2, 0) = (5, -2)
Endpoint G: (-1, -1) + (2, 0) = (1, -1)
Endpoint H: (3, -1) + (2, 0) = (5, -1)
Now, let's analyze the statements:
a) Line segments E'F' and G'H' do not intersect and are closer together than EF and GH.
This statement is false. E'F' and G'H' do not intersect, but they are not closer together than EF and GH. They are actually farther apart.
b) Line segments E'F' and G'H' intersect at (-2, 0) and are two times farther apart than EF and GH.
This statement is false. E'F' and G'H' do not intersect at (-2, 0). They have different coordinates for their endpoints.
c) Line segments E'F' and G'H' intersect at (0, -2) and are two times closer together than EF and GH.
This statement is false. E'F' and G'H' do not intersect at (0, -2). They have different coordinates for their endpoints.
d) Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.
This statement is true. E'F' and G'H' do not intersect, and they have the same distance between them as EF and GH.
Therefore, the correct statement is d) Line segments E'F' and G'H' do not intersect and are the same distance apart as EF and GH.

Which expression shows the value of a $7300 investment after it has grown by 2. 3% per year for 5 years?
The problem asks for the expression that represents the value of a $7300 investment after it has grown by 2.3% per year for 5 years.
To find the value of the investment after 5 years with a growth rate of 2.3% per year, we can use the formula for compound interest:
A = P(1 + r)^n
Where:
A is the final amount,
P is the principal amount (initial investment),
r is the interest rate (in decimal form), and
n is the number of years.
In this case, the principal amount is $7300, the interest rate is 2.3% (or 0.023 as a decimal), and the number of years is 5. Plugging these values into the formula, we get:
A = 7300(1 + 0.023)^5
Simplifying the expression gives us the value of the investment after 5 years with a growth rate of 2.3% per year.
