What is the area of a semicircle with a diameter of 20?

The length of the PM is 6 if ABCD is congruent to MNOP.

When it comes to geometry, two figures or objects are said to be congruent if they are the same size and shape, or if one is the mirror image of the other.

More specifically, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid motions including translation, rotation, and reflection. This indicates that either object may be exactly aligned with the other object by moving and reflecting it, but not by resizing it. If we can cut out and then perfectly match up two separate plane figures on a piece of paper, they are then congruent. I'm allowed to turn the paper over.

Here  both the given figures are congruent figures. So, their shape and size must be equal.

Therefore from the two figures, PM=DA

So, PM=6

Therefore, the length of the PM is 6 if ABCD is congruent to MNOP.

The percent of the original price was the price after markup will be 6.29%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

During a deal, a store offered a 25% rebate on a bed that initially sold for $890. After the deal, the limited cost of the bed was increased by 25%.

The marked-up price is given as,

⇒ $890 x (1 - 0.25) x (1 + 1.25)

⇒ $890 x 0.75 x 1.25

⇒ $834

The percentage is given as,

P = [(890 - 834) / 890] x 100

P = (56 / 890) x 100

P = 0.0629 x 100

P = 6.29%

The percent of the original price was the price after markup will be 6.29%.

Answer: 94%

Step-by-step explanation:

Find what percent of the original price this represents:

$834.375 / $890 = 0.9375

0.9375 × 100 = 93.75%

93.75% ≈ 94%

Round to the nearest whole number

The price after markup was 94% of the original price.

The inequality for the value of y can be given as -1/8 < -2/3y, where y < 3/16.

Inequality shows relation between two expression which are not equal to each others.

Let the required number is y.

To find the inequality that represents the -1/8 is less than the product of -2/3 and number y.

The product of -2/3 and y = -2/3y

The inequality for the y can be written as,

The solutions to the x and w variables are x = 2097153 and w = (6)⁻²/⁵

From the question, we have the following parameters that can be used in our computation:

1/7log(x - 1) = 3log(2)

3 ln(w + 6) = 5 ln(6)

Solving the equation (1), we have the following equation

1/7log(x - 1) = 3log(2)

Multiply both sides of the equation by 7

So, we have the following representation

log(x - 1) = 21log(2)

Apply the power rule of logarithm

log(x - 1) = log(2)²¹

By comparison, we have

x - 1 = (2)²¹

Evaluate the exponent

x - 1 = 2097152

So, we have

x = 2097153

Solving the equation (2), we have the following equation

3 ln(w + 6) = 5 ln(6)

Multiply both sides of the equation by 1/3

So, we have the following representation

ln(w + 6) = 5/3 ln(6)

Apply the power rule of logarithm

ln(w + 6) = ln(6)³/⁵

By comparison, we have

w + 6 = (6)³/⁵

So, we have

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

The required answer choices are (i)exponential decay (ii) linear and (iii) exponential growth

What are exponential growth and exponential decay?

Quantities that fluctuate quickly are subject to exponential growth and decay. The idea of geometric progression has been used to infer exponential growth and decay. Exponential growth or exponential decay are terms used to describe quantities that vary exponentially rather than continuously.

From question,

1) The first question is like, initially delivery van price is $25,000 after 2 years, the value of the van becomes $17,500

This means it is decaying. The difference between the initial price and after 2 years price is $7500.

To be linear, further after 2 years, or from start after 6 years, the price should be $10000. But it is given to be $12250.

Thus exponential decay.

2) In the second, Initially, a laptop had 100% battery life. After 3 hours, the laptop has 60% battery life. Thus the loss in 3 hours is (100 - 60) = 40%.

After 4 hours, the loss is (60 -20) = 40%

As the loss is the same in equal intervals of time, the decay is linear.

3) In the third one, A tiger reserve had an initial population of 20 tigers.

After 5 years the population was 30 tigers, thus the growth is (30-20) =10.

After 10 years, the population was 45 tigers. Thus the growth is (45-30) = 15.

Thus the increase is non-linear, and so is exponential growth.

0.9758 is the decay factor of the model

Given that:

The value of the U.S. dollar over time v(t) can be modeled by the following formula:

v(t) = 1.36(0.9758)^t , where t is the number of years since 2000

The form of the exponential decay models is f(t) = ab^t

where,

a is the initial value, b is the decay factor and t is the time

Comparing  f(t) = ab^t with v(t) = 1.36(0.9758)^t :

a = 1.36

To find the equation of the normal to the given curve at the point (-1,1), you can use the following steps:

Rewrite the given equation in the form "y = mx + b," where m is the slope of the curve and b is the y-intercept.

Find the slope of the curve at the point (-1,1). This can be done by taking the derivative of the equation and evaluating it at x = -1.

The slope of the normal line at the point (-1,1) is the negative reciprocal of the slope of the curve at that point. Calculate this value.

Use the point-slope formula to write the equation of the normal line in the form "y - y1 = m(x - x1)," where (x1, y1) is the point (-1,1) and m is the slope of the normal line.

Substitute the values for x1, y1, and m into the point-slope formula to obtain the final equation of the normal line.

For example, if the given equation is 2x^2 + 2y^2 - 4x + 4y = 12, you can follow these steps:

Rewriting the equation in slope-intercept form, we get: y = -x + 2

Taking the derivative of the equation, we get: y' = -1

The slope of the normal line is the negative reciprocal of the slope of the curve, which is 1/-1 = -1

Using the point-slope formula, we get: y - 1 = -1(x + 1)

Substituting the values into the point-slope formula, we get: y - 1 = -1x - 1

Thus, the equation of the normal line at the point (-1,1) is y - 1 = -1x - 1.

Answer:

Yes it is

Step-by-step explanation:

To find the percent increase, we need to calculate the difference between the new tuition and fees and the old tuition and fees, and then divide this difference by the old tuition and fees and multiply by 100%.

The difference between the new tuition and fees of $14,402 and the old tuition and fees of $1411 is $14,402 - $1411 = $12,991.

The percent increase is: ($12,991/$1411) * 100% = 9.2 * 100% = 920%

Therefore, the percent increase in tuition and fees between the fall of 1996 and the fall of 2018 was 920%, rounded to the nearest tenth percent.

Answer:

80 cards would have to sold before your average total cost per card falls to $10

Step-by-step explanation:

To find the number of cards you would have to sell to bring the average total cost per card down to $10, you can use the following formula:

number of cards = setup fee / (average total cost per card - cost per card)

Plugging in the values given in the problem, we get:

number of cards = $320 / ($10 - $6)

Solving this equation gives us:

number of cards = $320 / $4

Dividing 320 by 4 gives us a result of 80, so you would have to sell 80 cards before your average total cost per card falls to $10

Another approach is setting it up as y = mx+b

$10 = (320 + 6x) / x

Where x is the number of cards that you need to sell.

Solving for x, we get:

$10x = 320 + 6x

4x = 320

x = 80

The triangle has a value of x=22°.

The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. 180 degrees is the sum of the triangle's three angles.

Having three sides, a triangle is a form. Each kind of triangle has a unique name. The size of the angles and side lengths determine what kind of triangle it is (corners). Triangles can be classified as equilateral, isosceles, or scalene depending on how long their sides are.

The sum of all the angles in a triangle must be °

120° + (x+16)° + x° = 180°

2x + 136° = 180°

2x = 180° - 136°

2x° = 44°

x = 22°
