Tim bought a pair of running shoes marked 25% down at a price of $60

The formula to find the discount of an item on sale is

Where

Let k represent the original price

Substitute the values into the formula above

Hence, the original price, k, of the pair of Zeus running shoes is $240

Answer:

The answer is 108 I remember it because 9×12 is 108 and that's kinda what it is really.

For the month ended, the cost of goods sold was $600.

Cost of goods sold (COGS) is a crucial accounting formula that calculates the expenses incurred when a company sells its products or services. Therefore, $600 represents the cost of items sold for the just finished month.

A measurement of the cost of products sold throughout the accounting period is the cost of goods sold (COGS). It is computed by adding the ending inventory after deducting the beginning inventory from the cost of the products bought during the accounting period.

The following formula is used to determine Dig the Dogs, Inc.'s cost of goods sold for the just ended month: Starting inventory is zero, and the cost of the goods was $900. $300 is the ending inventory.

Beginning Inventory = 0

Cost of Goods Purchased = $900

Ending Inventory = $300 .

COGS = Beginning Inventory + Cost of Goods Purchased - Ending Inventory  COGS = 0 + 900 - 300   = $600

Therefore, the cost of goods sold for the month ended is $600.

Hello,

Answer:

We can start by rationalizing the denominators of each fraction.

For the first fraction, we multiply the numerator and denominator by the conjugate of the denominator, which is √4 - √5:

1/√4+√5 = 1/√4+√5 × (√4 - √5)/(√4 - √5)

= (√4 - √5)/(4 - 5)

= (√4 - √5)/(-1)

For the second fraction, we multiply the numerator and denominator by √5 - √6:

1/√5+√6 = 1/√5+√6 × (√5 - √6)/(√5 - √6)

= (√5 - √6)/(5 - 6)

= (√5 - √6)/(-1)

We can do the same for the remaining fractions:

1/√6+√7 = (√6 - √7)/(-1)

1/√7+√8 = (√7 - √8)/(-1)

1/√8+√9 = (√8 - √9)/(-1)

Now we can simplify the expression:

1/√4+√5 + 1/√5+√6 + 1/√6+√7 + 1/√7+√8 + 1/√8+√9

= (√4 - √5)/(-1) + (√5 - √6)/(-1) + (√6 - √7)/(-1) + (√7 - √8)/(-1) + (√8 - √9)/(-1)

= (√4 - √5 + √5 - √6 + √6 - √7 + √7 - √8 + √8 - √9)/(-1)

= (√4 - √9)/(-1)

= √9 - √4

= 3 - 2

= 1

Therefore, the expression simplifies to 1, which is equal to the right-hand side of the equation.

Good luck

Answer:i think its 115 degres

Step-by-step explanation:

By definition, the x-coordinate of the terminal point is equal to cos t and the y-coordinate is equal to sin t. This allows us to easily find the values of sin t and cos t. To find tan t, we use the formula tan t = sin t / cos t, which we can substitute with our previously found values for sin t and cos t.

First need to understand what is meant by the terms "terminal point" and "unit circle". The unit circle is a circle with a radius of 1, centered at the origin of the coordinate plane. The terminal point is the point where the circle intersects with a line that starts at the origin and passes through an angle t measured in radians.
To find sin t and cos t, we need to look at the coordinates of the terminal point. Let's call the x-coordinate of the terminal point x' and the y-coordinate y'. By definition, x' = cos t and y' = sin t. Therefore, sin t = y' and cos t = x'.
To find tan t, we use the formula tan t = sin t / cos t. Substituting in our values for sin t and cos t, we get:
tan t = y' / x'
So, to summarize:
- sin t = y'
- cos t = x'
- tan t = y' / x'
In summary, we can use the unit circle to determine the values of sin t, cos t, and tan t for any angle t measured in radians. The terminal point on the unit circle is the point where the circle intersects with a line passing through the origin at angle t.

The inequality that represents the cost c per 14 squares for a new carpet with a budget of $700 is: c ≤ 700/14 = 50 Therefore, the answer is:

The inequality is c ≤ 50.

Assuming that the price of the carpet is constant per square foot, we can write the following inequality to represent the cost c per 14 squares:

c/14 ≤ 700

This inequality states that the cost per 14 square feet (c/14) cannot exceed $700, which is the total amount of money available to purchase the carpet.

To write an inequality representing the cost of a new carpet per 14 square feet, we need to first define the cost per square foot. Let's say the cost per square foot is $x. Then, the cost of the carpet for 14 square feet would be 14x.

Since we have a budget of $700, we can write the inequality:

14x ≤ 700

This inequality represents that the cost of the carpet for 14 square feet should be less than or equal to $700. We can solve for x by dividing both sides by 14:

x ≤ 50

This means that the cost per square foot of the carpet should be less than or equal to $50 for it to fit within the budget of $700.

a) y = (460 - 2s) / 22. b) Substituting this value for x into either of the original equations, we can solve for y: y = -30. c) Substituting this value for x into either of the original equations, we can solve for y: y = 131. d) This equation is always true, which means that there are infinitely many solutions for x and s.

a) In order to solve for x and y in the system of equations:
y = 12 - 2x
y = 20x - s
We can set the two expressions for y equal to each other:
12 - 2x = 20x - s
Simplifying, we get:
22x = s + 12
x = (s + 12) / 22
Substituting this value for x into either of the original equations, we can solve for y:
y = 12 - 2((s + 12) / 22)
y = (484 - 2s - 24) / 22
y = (460 - 2s) / 22

b) In order to solve for x and y in the system of equations:
y = -30
y = -2 - 22x + 11
We can set the two expressions for y equal to each other:
-30 = -2 - 22x + 11
Simplifying, we get:
-22x = 41
x = -41 / 22
Substituting this value for x into either of the original equations, we can solve for y:
y = -30

c) In order to solve for x and y in the system of equations:
y = 28 - 34x + 11
x = 34 - 25y / 15
We can substitute the expression for y from the first equation into the second equation:
x = 34 - 25(28 - 34x + 11) / 15
Simplifying, we get:
x = 34 - (5/3)(28 - 34x + 11)
x = 34 - (5/3)(39 - 34x)
x = (217/17) - (10/17)x
(27/17)x = (217/17) - 39
x = -2
Substituting this value for x into either of the original equations, we can solve for y:
y = 28 - 34(-2) + 11
y = 131

d) In order to solve for x, y, and s in the system of equations:
y = -17/3
15x = 3y + s
We can substitute the expression for y from the first equation into the second equation:
15x = 3(-17/3) + s
15x = -17 + s
Solving for s, we get:
s = 15x + 17
Substituting this expression for s into either of the original equations, we can solve for y:
y = -17/3
Finally, we can solve for x by substituting the expression for s into the equation:
15x = 3(-17/3) + (15x + 17)
15x = -17 + 15x + 17
0 = 0
This equation is always true, which means that there are infinitely many solutions for x and s.

Protractor postulate: given any angle, we can express its measure as a unique real number from 0 to 180 degrees.

The protractor postulate is a fundamental concept in geometry that establishes a way to measure angles using a protractor. According to this postulate, every angle can be uniquely represented by a real number between 0 and 180 degrees.

A protractor is a geometric tool with a semicircular shape and marked degrees along its edge. To measure an angle using a protractor, we align the center of the protractor with the vertex of the angle and the baseline of the protractor with one side of the angle. We then read the degree measure where the other side of the angle intersects the protractor.

The protractor is divided into 180 degrees, with 0 degrees being the starting point at the baseline of the protractor, and 180 degrees being at the opposite end of the baseline. By aligning the protractor with an angle, we can determine its measure as a real number within this range.

For example, if we measure an angle using a protractor and find that the other side intersects the protractor at 45 degrees, we can express the measure of the angle as 45 degrees. Similarly, if the intersection point is at 90 degrees, the angle measure would be 90 degrees. The protractor postulate guarantees that these angle measures are unique within the range of 0 to 180 degrees.

It is important to note that the protractor postulate assumes that angles can be measured using a protractor and that the measurement is accurate and reliable. The postulate provides a consistent and standardized way to assign a numerical value to an angle, allowing for precise communication and comparison of angles in geometric contexts.

In summary, the protractor postulate establishes that the measure of any angle can be expressed as a unique real number between 0 and 180 degrees. This concept is fundamental in geometry and allows for the measurement, comparison, and communication of angles using a protractor.

The real values of $c$ for which $4x² + 14xc + c$ is the square of a binomial are $c = 0$ and $c = \frac{4}{49}$.

To determine the real values of $c$ for which the expression $4x² + 14xc + c$ is the square of a binomial, we need to find the conditions under which it can be factored as $(ax + b)²$, where $a$ and $b$ are constants.

Expanding $(ax + b)²$, we have $(ax + b)² = a²x² + 2abx + b²$. Comparing this with $4x² + 14xc + c$, we can set up the following equations:

$a² = 4$ (equating the coefficients of $x²$)

$2ab = 14c$ (equating the coefficients of $x$)

$b² = c$ (equating the constant terms)

From the first equation, we find that $a = \pm 2$. Substituting this value into the second equation, we have:

$2(\pm 2)b = 14c$

$\Rightarrow \pm 4b = 14c$

$\Rightarrow b = \pm \frac{14c}{4}$

$\Rightarrow b = \pm \frac{7c}{2}$

Finally, substituting the values of $a$ and $b$ into the third equation, we get:

$\left(\pm \frac{7c}{2}\right)² = c$

$\Rightarrow \frac{49c²}{4} = c$

$\Rightarrow 49c² = 4c$

$\Rightarrow 49c² - 4c = 0$

$\Rightarrow c(49c - 4) = 0$

Now, we can solve this equation to find the values of $c$:

$c = 0$: This is one possible solution.

$49c - 4 = 0 \Rightarrow 49c = 4 \Rightarrow c = \frac{4}{49}$: This is another possible solution.

Therefore, the real values of $c$ for which $4x² + 14xc + c$ is the square of a binomial are $c = 0$ and $c = \frac{4}{49}$.

To find a decimal approximation of the radical expression using the given notation, you can use the following steps:
1. Identify the function f'(x) as the derivative of the original function f(x).
2. Find the value of Δx, which is the change in x.
3. Apply the formula f'(x)Δx to approximate the change in the function value.

For example, let's say f(x) is the radical expression, which could be represented as f(x) = √x. To find f'(x), we need to find the derivative of f(x) with respect to x:
f'(x) = 1/(2√x)
Now, let's say we want to approximate the value of the expression at x = 103. We can choose a small value for Δx, such as 0.001:
Δx = 0.001
Now, we can apply the formula f'(x)Δx:
Approximation = f'(103)Δx = (1/(2√103))(0.001)
After calculating the expression, we get:
Approximation = 0.049 (rounded to three decimal places)
So, the value found using f'(x)Δx for the radical expression at x = 103 is approximately 0.049.
