Mr. Krumm paid $9.27 for a tie that had a 3% sales tax added on. So, the tie cost $231.75 before the tax was included.

To find out how much the tie cost before the tax was included, we need to first calculate how much of the total price was due to the tax. We know that the total price Mr. Krumm paid was $9.27, and that this price included a $3% sales tax.

To calculate the amount of tax that was included in the price, we can start by setting up an equation:

0.03x = 9.27 - x

Here, x represents the cost of the tie before the tax was included. We know that the tax is 3% of this cost, which is why we're multiplying it by 0.03.. We're also subtracting x from 9.27 to get the amount of tax that was added on.

Simplifying this equation, we get:

0.04x = 9.27

Dividing both sides by 0.04, we get:

x = 231.75

So the tie cost $231.75 before the tax was included.

In summary, Mr. Krumm paid $9.27 for a tie that had a 3% sales tax added on. To find out how much the tie cost before the tax was included, we set up an equation and solved for the cost of the tie (x) before the tax was added. The answer is that the tie cost $231.75 before the tax was included.

To check our answer, we can verify that the number of quarters is 1.7 times the number of dimes, which would be 102. And the total value of her dimes and quarters would be:  $31.50

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's start by using algebra to solve the problem.

Let x be the number of dimes that Carol has saved.

According to the problem, there are 70% more quarters than dimes. We can express the number of quarters in terms of x as 1.7x, since 1.7 times the number of dimes is equal to the number of quarters.

We also know that the combined value of her quarters and dimes is $31.50. We can express this as an equation:

0.10x + 0.25(1.7x) = 31.50

Simplifying and solving for x, we get:

0.10x + 0.425x = 31.50

0.525x = 31.50

x = 60

Therefore, Carol has 60 dimes.

Therefore, To check our answer, we can verify that the number of quarters is 1.7 times the number of dimes, which would be 102. And the total value of her dimes and quarters would be:

60 * $0.10 (dimes) + 102 * $0.25 (quarters) = $31.50

which matches the information given in the problem.

Consider the following example.

IN here, we have angles 1 and 2 measured with respect the horizontal line that passes through point A. Note that angle 2 is related to points A and C. In this case, angle is under the horizontal line that passes through A. Then, angle 2 is the angle of depression from point A to point C. Every angle that is under the horizontal line would receive the name of angle of depression. In the same manner, since angle 1 is above the horizontal line, then it is an elevation angle from point A to point C. In fact, every angle that is above the horizontal line, would receive the name of elevation angle.

Coming back to our problem, we can see that angle 2 is formed by the horizontal line that passes through the radar and the line that connects the plane to the radar. This angle would be above the horizontal line of the radar. Then, according to our previous explanation, this means that angle 2 is an elevation angle from the radar to the plane.

Answer:

Yes

Step-by-step explanation:

There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.

Answer:

Step-by-step explanation:

No, because \((x^2-x)/2\) does equal \(x^2/2-x/2\). Honestly, it really depends on the value of x, as it provide whether or not the expression is divisible by 2.

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\(\frac{f(b)-f(a)}{b-a}\)

Here [ a, b ] = [ - 3, 7 ] , then

f(b) = f(7 ) = - 7² + 6(7) + 17 = - 49 + 42 + 17 = 10

f(a) = f(- 3) = - (- 3)² + 6(- 3) + 17 = - 9 - 18 + 17 = - 10

average rate of change = \(\frac{10-(-10)}{7-(-3)}\) = \(\frac{10+10}{7+3}\) = \(\frac{20}{10}\) = 2

After considering the given data we conclude that the value of CE = x = 6, under the condition that the given figure is AEC. The set up proportion is 6/4 = 1.5

In the given figure, we have two right-angled triangles ABC and CBE such that triangle ABC meets triangle CBE at a common side of BC. The base of triangle ABC is 8 and the base of triangle CDE is 4. We need to find the length of CE.
We can see that triangle ABC and triangle CBE are similar triangles because they share an angle (angle B) and have a common side (BC). Therefore, we can write:
AB/BC = CB/CE
We know that AB = AC - CB = √(AC² - BC²) = √(8² - BC²) and CB = CE - BE = √(CE² - 4²).

Substituting these values in the above equation, we get:
√(8² - BC²)/BC = CB/CE
√(8² - BC²)/BC = √t(CE² - 4²)/CE
Squaring both sides of the equation, we get:
(8² - BC²)/BC² = (CE² - 4²)/CE²
Multiplying both sides by BC² × CE², we get:
(8² - BC²) × CE² = (CE² - 4²) × BC²
64CE² - BC² × CE² = CE² × BC² - 16
80CE² = BC² × CE² + 16
Substituting BC = BE + EC = BE + CE/3 (because triangle CBE is a right-angled triangle), we get:
80CE² = (BE + CE/3)² × CE² + 16
80CE² = (BE×CE + CE³/3)² + 16×CE²
Substituting BE = AB - AE and AB = √(8² - BC²), we get:
80CE⁴ = ((√(8² - BC²) × CE) + (CE/3)³)² + 16×CE²
Substituting BC with √(8² - BC²), we get:
80CE⁴ = ((√(8² - (√(8² - BC²))²) × CE) + (CE/3)³)² + 16×CE²
80CE⁴ = (√64 - BC²) × CE) + (CE/27))² + 16×CE²
80CE⁴ = (64×CE⁴ - BC×BC×CE×CE + 32×√(64-BC×BC)×CE×CE/27 + CE×CE/729) + 16×CE×CE
0 = 64×CE×CE - BC×BC×27×CE×CE + 32×√(64-BC×BC)×27×CE×CE + CE×CE/5
0 = 3200×CE×CE - 27×(BC⁴)×5
Solving for CE, we get:
3200 × CE² = 27 × (8⁴)
3200 × CE² = 27 × (4096)
3200 ×CE² = 110,592
CE² = 110,592 / 3200

Step-by-step explanation:

9.5 miles / .25 = 38

The first mile is 1.25 so we do this

37 * .35 = 12.95

12.95 + 1.25 = 14.2

14.2 + 1.25 + 1.25(two additional passengers) = 16.70

A maximum of 105 number of 120 kilograms can be loaded in the container.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Weight of each crate = 120 kg

The greatest weight loaded in the container = 27500 kg

Weight already loaded in the container = 14900 kg

Now,

Since, Weight already loaded = 14900 kg

Let number of 120 kilograms loaded in the container = x.

Hence, Weight of x = 120 kg

So, After combined we get;

Weight nor be greater than the capacity of the container.

Hence, we can formulate;

14900 + 120x ≤ 27500

Subtract 14900 we get;

120x ≤ 27500 - 14900

120x ≤ 12600

x ≤ 12600 ÷ 120

x ≤ 105

Thus, A maximum of 105 number of 120 kilograms can be loaded in the container.

The statement "A histogram with the hills to the far left means the image is overexposed" is not accurate. In fact, a histogram with the hills to the far left indicates that the image is underexposed, not overexposed.

A histogram is a graphical representation of the distribution of pixel values in an image. It displays the frequency of occurrence of different tonal values. The horizontal axis represents the tonal values, while the vertical axis represents the frequency or number of pixels.

When the hills of the histogram are concentrated towards the left side, it means that a significant portion of the image has darker or lower tonal values. This indicates an underexposed image, where the exposure settings were insufficient to capture enough light, resulting in a darker overall appearance.

Conversely, an overexposed image would have the hills of the histogram concentrated towards the right side, indicating that a significant portion of the image has brighter or higher tonal values.

Therefore, the correct interpretation is that a histogram with the hills to the far left means the image is underexposed, not overexposed.
