Answer:

-515

Step-by-step explanation:

In this example the first value is −15 and every value afterwards is 20 less.

After substituting these values to above formula, we obtain:

All we have to do is add 25 twenties or 25 x 20 = 500 and -15 - 500 = -515

The required 28 th term of the given arithmetic sequence is given as -555.

Arithmetic progression is the series of numbers that have common differences between adjacent values that are equal.

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Given sequence,
-15,-35,-55,-75,...

From the above sequence,
The first term, a = -15
Common difference d = -35 +15 = -20

nth term is given as,
nth = a + (n - 1)d
nth = -15 -20 (n - 1)

Now put n = 28
28th = -15 -20(28 - 1)
       = -15 - 540
       = -555

Thus, the required 28 th term of the given arithmetic sequence is given as -555.

Answer:

1 Pair of Jeans cost $35

1 Shirt costs $21

Step-by-step explanation:

$231 - $133= $98

$133 - $98 = $35 --- Pair of Jeans

$35 × 2 = $70

$133 - $70 = $63

$63/3 = $21 --- Shirt

The cost of each pair of jeans and each shirt can be found by setting up and solving simultaneous equations. The cost of each pair of jeans is $27, and the cost of each shirt is $25.

This problem can be solved using the method of simultaneous equations. We'll first form two equations based on the given information. Let's assume the cost of a pair of jeans is 'x' dollars and the cost of a shirt is 'y' dollars.

Let's simplify the second equation by dividing it by 3, which makes it x + 2y = 77. Subtract this from the first equation to eliminate 'x'. You're left with y = 25. Substitute y = 25 into the simplified second equation to get x = 27. So each pair of jeans costs $27 and each shirt costs $25.

Solution:

Here the Quadrilateral in inscribed in a circle with center O named as DUCK

So angle K and  U are opposite to each other

We know that the angle of Quadrilateral inscribed in a circle are supplemenatry angles

Hence

∠U+∠K=180

Or The ∠K=1/2*m∠arc(DUC).

Hence depending on the given value for arc measure or angle of quadrilateral we calculate the angle K

The required value of a number of people is 20 who don't do either.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

here, we have,

Column 1 has the entries run, do not run, and total. Column 2 is called lift weights, and it has the values 40, blank, and 65. Column 3 is captioned "do not lift weights" and has entries blank, x, and blank. Column 4 is called total and has the entries 75, blank, and 120.

As per the given information, the required solution would be as:

The number of people who do not run or lift weights by first determining that 55 individuals do not lift weights and 35 people run but do not lift weights. When you subtract 35 from 55, you get 20 people who don't do either.

Thus, the required value of a number of people is 20 who don't do either.

The number x represents the number of people who do not run and do not lift weights. To calculate x, subtract the number of people who lift weights from the total number, then subtract the number of people who run and lift weights.

To find the number that x represents, we can use the information given in a table with a row and column structure. From the total number of people (120) and the number of people that lift weights (65), we deduct the number that run and lift weights (40), leaving us with the number of people who either do not run or do not lift weights.

The total number of people that run is given as 75. Therefore, the number who do not run is 120 - 75 = 45. We know that 65 people lift weights, so by subtraction, 120 - 65 gives us the total number of people who do not lift weights.

Now, using the total number of people who do not lift weights, we can calculate the value of x, which represents the number of people who do not run and also do not lift weights. Subtracting the number of people who run but do not lift weights from the total number who do not lift weights gives us:

Number of people who do not lift weights = Total number of people - Number of people who lift weights

Number of people who do not lift weights = 120 - 65 = 55

Therefore, x equals 55 - 40, since 40 is the number of people who run and lift weights.

x = 55 - 40 = 15

That's TRUE but I predict by the time your grandchildren are in school we'll have stop teaching that geometric things are sets of points.  That's a bad way to think about things.

Its True a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.

Given that,
A circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle. Whether it's true or false is to be justified in a statement.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.

Here, the distance of the point on the circumference of the circle has a fixed distance from the center.

Thus, it's true a circle is the set of all points in a plane that are equidistant from a fixed point called the center of the circle.

Selling price = $28

Step-by-step explanation:

Cost price = $20

Selling price = ?

Percent markup = 40%.

Percentage markup is the difference between a products selling price and cost as a percentage to the cost.

% mark up = (selling price - cost price) / (cost price) * 100

[(Selling price - 20) / 20 ] * 100 = 40

40 / 100 = (selling price - 20) / 20

0.4 * 20 = selling price - 20

8 = selling price - 20

Selling price = $(8 + 20)

Selling price = $28.

The selling price was $28

Answer: The selling price is $28

Step-by-step explanation: If the CD set was bought at the cost of $20 and sold at a selling price of $20 plus 40% (or 0.4), then we should start by calculating the value of 40% of the cost price, which would then be added to the cost price to arrive at the selling price.

The calculation is as follows;

Mark up = 20 x 0.4

Mark up = 8

Selling price = Cost price + Mark up

Selling price = 20 + 8

Selling price = 28

Therefore the selling price is $28

Answer:

The answer to your question is 42°

Step-by-step explanation:

Data

m∠BOC = 6x - 6

m∠AOB = 5x + 8

m∠BOC = ?

Process

We know that the segments OA ⊥ OC so they are complementary angles.

1.- The sum of complementary angles equals 90°

                 m∠BOC + m∠AOB = 90°

2.- Substitution

                6x - 6 + 5x + 8 = 90°

3.- Solve for x

                6x + 5x = 90 + 6 - 8

4.- Simplify

                       11x = 88

5.- Result

                          x = 88/11

                          x = 8

6.- Calculate m∠BOC

             m∠BOC = 6(8) - 6

                            = 48 - 6

To find the actual length of each leg of the Apollo Lunar Module, use the given scale of 1 to 50. Measure the length of the leg on the drawing and multiply it by the scale factor.

Explanation:

To find the actual length of each leg of the Apollo Lunar Module, we need to use the given scale of 1 to 50. This means that 1 unit on the drawing represents 50 units in real life. First, measure the length of the leg on the drawing. Let's say it measures 3 centimeters. To find the actual length, multiply the measured length by the scale factor: 3 cm x 50 = 150 centimeters. Therefore, each leg of the Apollo Lunar Module is 150 centimeters long.

Answer: 90% decrease

Step-by-step explanation: First determine whether the number is increasing or decreasing. Since it changes from 2,000 to 200, it's going down so it's decreasing.

Now to find the percent decrease, we divide the

amount of change by the original number.

The amount of change is the difference between the two numbers

which in this case is 2,000 - 200 and the original number is 2,000.

[tex]So[/tex] [tex]we[/tex] [tex]have[/tex] [tex]\frac{2,000 - 200}{2,000}[/tex].

2,000 - 200 is 1,800.

So we're left with 1,800/2,000 and dividing

2,000 into 1,800 gives us 0.9.

Remember however that our problem is

asking for a percent, not a decimal.

So we need to write 0.9 as a percent and we can do

that by multiplying it by 100 and adding the percent sign.

So 0.9 becomes 90%.

So when a number changes from 2,000 to 200,

it has decreased by 90%.
