The original price is $171.59 and the price during sales is $148.37 then the percent markdown will be 13.53%.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Original selling price = $171.59

Price during sales = $148.37

Then, the percentage markdown will be,

% markdown = (171.59 - 148.37)/171.59 × 100

= 23.22/171.59 × 100

% markdown = 13.53%

The height of the trapezoidal glass window is \(3\frac{1}{2}\) inches.

What is a trapezoid?

A trapezoid is a four-sided flat shape with straight sides that has two parallel sides.

We can use the formula for the area of a trapezoid to solve for the height of the window:

Area = (base1 + base2) / 2 * height

Substituting the given values, we get:

\(12\frac{1}{4} = (4 \frac{1}{2} + 2 \frac{1}{2} )\) * height

First, let's simplify the bases:

\(12\frac{1}{4}\) = 7 / 2 * height

Now we can solve for the height by dividing both sides by 7/2:

height = 2 * \(12\frac{1}{4}\) / 7

height = 2 * 49 / 28

height = 98 / 28

height = \(3\frac{1}{2}\) inches

Therefore, the height of the trapezoidal glass window is \(3\frac{1}{2}\) inches.

We have to find the slope and the y-intercept of the linear function shown.

For doing so, we will take two points that pass through the line and we will use the formula:

for finding the slope. In this case, two of those points could be:

Using them, and replacing onto the slope formula we get:

This is, the slope is - 3/4.

For the y-intercept, we see that the function passes through the point:

Equation at the end of step 1

 ((2•3x2) -  x) -  2

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  6x2-x-2  

The first term is,  6x2  its coefficient is  6 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  -2  

Step-1 : Multiply the coefficient of the first term by the constant   6 • -2 = -12  

Step-2 : Find two factors of  -12  whose sum equals the coefficient of the middle term, which is   -1 .

     -12    +    1    =    -11  

     -6    +    2    =    -4  

     -4    +    3    =    -1    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  3  

                    6x2 - 4x + 3x - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   2x • (3x-2)

             Add up the last 2 terms, pulling out common factors :

                    1 • (3x-2)

Step-5 : Add up the four terms of step 4 :

                   (2x+1)  •  (3x-2)

            Which is the desired factorization

Final result :

 (3x - 2) • (2x + 1)

The measure of <1 is 147 degree.

Given:

m∠2 = 12x - 15

m∠7 = 3x + 21

Since angles 2 and 7 are alternate Exterior angles, they are congruent.

So, 12x - 15 = 3x + 21

12x - 3x = 21 + 15

9x = 36

x = 4

So, <2 = 12x - 15= 48 - 15 = 33

Now, <1 + <2 = 180 (Linear Pair)

<1 + 33 = 180

<1 = 147 degree

Thus, the measure of <1 is 147 degree.

Traditionally, the spatial intervals between typographic elements are called "kerning" and "tracking."

1. Kerning: Kerning refers to the adjustment of space between individual pairs of characters.

It involves modifying the spacing between specific letter combinations to achieve better visual harmony and readability.

Kerning is particularly important when dealing with letter pairs that may appear awkward or visually unbalanced, such as "AV" or "To."

2. Tracking: Tracking, also known as letter-spacing, involves adjusting the overall spacing uniformly between all characters in a text block or a selected range of text.

It affects the spacing between all letters and can be used to create a more open or compact appearance of the text.

Increasing the tracking value creates more space between characters, while decreasing it brings the characters closer together.

Both kerning and tracking play crucial roles in typography to ensure legibility, readability, and overall visual appeal. Designers use these techniques to achieve optimal spacing between characters and create well-balanced and aesthetically pleasing typographic layouts.

Answer:

Let's define.

L = rate at which the large pump fills the pool.

S = rate at which the small pump can fill the pool.

We have two relations:

"Two large and 1 small pump can fill a swimming pool in 4 hours."

(2*L + S)*4h = 1

"One large and 3 small pumps can also fill the same swimming pool in 4 hours."

(L + 3*S)4h = 1

Then we have the system of equations:

(2*L + S)*4h = 1

(L + 3*S)4h = 1

To solve this system, we need to isolate one of the variables in one of the equations, i will isolate S in the first equation:

S = 1/4h - 2*L

Now we can replace that in the second equation:

(L + 3*(1/4h - 2*L))4h = 1

L + (3/4h) - 6*L = 1/4h

-5*L = 1/4h - 3/4h = -2/4h

L = (2/4h)*(1/5) = (2/20h) = 1/10h

This means that one large pump needs 10 hours to fill one pool.

With this, we can find the value of S:

S = 1/4h - 2*L = 1/4h - 2/10h = 5/20h - 4/20h = 1/20h

This means that a small pump needs 20 hours to fill a pool.

Now we can answer:

How many hours will it take 4 large and 4 small pumps to fill the swimming pool?

We need to solve the equation:

(4*(1/10h) + 4*(1/20h))*T = 1

We need to find the value of T.

T = 1/((4*(1/10h) + 4*(1/20h)) = 1.67 hours.

This means that 4 large and 4 small pumps need 1.67 hours to fill a pool.

The statistics z is -1.878 and the p value is 0.0302

Given,

Number of random sample selected, n = 6967

Number of surveys returned, x = 1331

Estimated proportion of return rate;

p = 1331/6967 = 0.192

Significance level, ∝ = 0.01

z would represent the statistic

We investigate the assertion that the return rate is less than 20%, and the following hypotheses are tested:

Null hypothesis, p₀ ≥ 0.2

Alternative hypothesis, p₀ < 0.2

The statistics, z = (p - p₀) / √(p₀(1 - p₀)/n)

That is,

z = (0.191 - 0.2) / √(0.2(1 - 0.2)/6967) = -1.878

Using the alternative hypothesis and the following probability, we can now get the p value:

p value  = p(z < - 1.878) = 0.0302

We fail to reject the null hypothesis when the p value exceeds the significance level of 0.01 and there is insufficient evidence to support the conclusion that the return rate is less than 20% at 1% of significance.

A world without engines is certainly an appealing idea. Although engines are a vital transportation source that allow us to move around and travel much faster and efficiently, passenger vehicles are a major pollution contributor. they produce large amounts of carbon monoxide, nitrogen oxides, and other forms of pollution. Removing all engines would definitely have downsides, but the significant amount of help it would provide towards lowering pollution rates would be extremely impactful towards our environment and earth. Engines are important parts of human life, and getting things done faster is much more efficient, without engines humans would have to do many things by hand and it would slow production of many things that are necessities. There are also many situations regarding human lives that require the fastest transportation possible, and without engines many things wouldn't get done fast enough. In conclusion, a world without engines would have many benefits towards the environment, however, we've grown to be too dependent on these machines and without them production of many things would start to slow and many trips around the world would be near impossible or extremely delayed.

A. The proportion we can set up is: c/a = d/b, and B. x = (c * b) / a. This gives us the value of x in terms of the lengths of the other segments.

A) The corresponding sides in similar triangles are proportional, so we can use this fact to set up a proportion between the sides of triangles BED and BCA. Let's call the length of segment BC "a", the length of segment AC "b", the length of segment BE "c", and the length of segment DE "d".
The proportion we can set up is:
c/a = d/b
This is because we know that triangle BED is similar to triangle BCA, so the ratio of the lengths of their corresponding sides must be the same.

B) We can now use the proportion to solve for x, which is the length of segment DE. We can start by cross-multiplying the proportion:
c * b = d * a
Then, we can isolate for x by dividing both sides by the coefficient of x:
x = (c * b) / a
This gives us the value of x in terms of the lengths of the other segments.

The division rest of 74 by 7 equals 4, and the value of the quotient is 10. Proof: 74 = (7×10) + 4.

Step-by-step explanation:

hope this helped and is that iready??

The remainder of 74 divided by 7 is 4.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

When a number is divided by another number, the number which is being divided is the dividend. Divisor is the number which divides the dividend.

Quotient is the value after the division process.

Remainder is the remaining value after the division.

If the dividend is completely a factor of divisor, remainder will be zero.

Otherwise there will be a non zero number as the remainder.

74 is not a multiple of 7.

70 is the multiple of 7 which is closest to 74.

Remainder = 74 - 70 = 4

Hence the remainder is 4.

Answer:

Speed of Airplane is 260 miles per hour and the time taken is 8 hours

Speed of sports car is 65 miles per hour and the time taken in 3 hours

Step-by-step explanation:

Let the speed of airplane be "X" and the speed of Sports car be Y

Given-

Speed of the  airplane is 4 times the speed of the sports car

\(X = 4Y\)

Also,

Airplane could fly 2080 miles in 5 more hours than it look the sports e to drive 195 miles

Time taken by sports car to travel 195 miles is \(\frac{195}{Y}\) hours

Time taken by airplane to travel 2080 miles is 5 hours more than \(\frac{195}{Y}\) hours

\(\frac{2080}{X} = \frac{195}{Y} +5\)

Substituting value of X in above equation, we get -

\(\frac{2080}{4Y} = \frac{195}{Y} +5\\\frac{2080 - (195*4)}{4Y} = 5\\Y = 65\)miles per hour

Speed of Air plane \(4 * 65 = 260\) miles per hour

Time taken by Sports car to travel 195 miles is  \(3\) hours

Time taken by airplane to travel 2080 miles is 8 hours

Ok, so. You can think of the mean being acually mean because you have to do more work. When solving for the mean you add all the answers together then divide by the amount of numbers you have. For example,  you have the numers (1, 2, 3) add them together (1+2+3) to get 6 then divide by 3 (6/3) to get a mean of two. The median is also fairly easy to remember. You line your numbers up least to greatest, left to right. and mark one off of each side at a time. If you have a even amount of numbers and reach the center, you add the two centers together then divide by to to get the median. If you have an odd amount of numbers, there should be one in the exact center left over.

Step-by-step explanation:

Mean) 3+8+10+15=36, 36/4=9 ANSWER=9

Median) 8+10=18, 18/2=9 ANSWER=9
