Find the eighth term of each geometric sequence. 10,5,2.5, . . . . .

The most commonly used explicit of an arithmetic sequence is given as,

an = a + (n - 1) d

Each term in the sequence can easily be solved/computed without knowing the other terms in the sequence. Now by using the given information, we can say that,

2nd row seat = 12+ 1x2

3rd row seat = 12 + 2 x2

nth seat = 12 + (n-1) x 2

16th row seat = 12 + (16–1) x2 = 42

Since the number of seats is increasing at a constant rate, we can calculate the average number of seats in each row by taking the average of the first and last rows,

Average number of seats per row = (12 +42)/2= 27.

So total seats = average per row x number of rows.

= 27 x 16 = 432.

The slope of the line is the y-intercept, and 40 caramel apples are required to raise $200.

Students in the math club are supposed to sell enough caramel apples and popcorn balls to generate $200, according to the question. This expression's line equation has the following form:

Expression's slope is 4/5(200) = 4(40) = 160.

40 caramel apples are equal to 200 minus 160.

Thus, 40 caramel apples are required, and the slope of a line is represented by the y-intercept.

Answer:

840

Step-by-step explanation:

360 divided by 3 = 120 Visitors per Hour

Now you do you 120 x 7 which equals to 840

Hope this helps ^^

Step-by-step explanation:

360 visitors in 3 hours.

that gives us the ratio

360/3

and because a ratio is nothing else than a fraction with a special meaning, we cab simplify this like any other fraction too :

360/3 = 120/1 = 120

in other words, out of the 3-hour ratio we know that there are 120 visitors in 1 hour.

and now it is easy to use it to find the number of visitors for 7 hours.

remember, if we multiply one part of the fraction by something, we need to multiply also the other part by the same number so that the value of the fraction stays the same.

in other words, we can only do

a/b × c/c

so, if we multiply the bottom part of our ratio by 7 (to go to 7 hours), we also have to multiply the top part by 7 to keep the ratio :

120/1 × 7/7 = 840/7

that tells us that there are 840 visitors in 7 hours.

Step-by-step explanation:

You divide 4005 by 101 and find the numbers that repeat as a decimal. In this case, the repeating decimals are 6534.

Answer:

x= 10 , DEG = 60 , GEF = 40

Step-by-step explanation:

Firstly the angle DEH is 90 degrees because of the red square indicating it.

That means the angle DEF is also 90 degrees.

To find the x you would do:

6x + 4x = 90

now add the 6x and 4x together:

10x = 90

now divide 10 from both sides to isolate the x:

x = 10

now you have your x which is 10.

For angle DEG you plug in the 10 for the x:

DEG = 6(10)

after that you multiply the 6 and 10:

DEG = 60

For angle GEF you plug in the 10 for the x:

GEF = 4(10)

after that you multiply 4 and 10:

GEF = 40

The simplification by combining like terms of 2(h + 2g) - (g - h) is 3(h + g).

According to the given question.

We have an expression 2(h + 2g) - (g - h).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression

2(h + 2g) - (g - h).

Here 2h, and h and 2g and -g are the like terms.

So, we add and subtract coeffcients of h and g to simplify the given expression.

Therefore, the simplification of 2(h + 2g) - (g - h) is given by

= 2(h + 2g) - (g - h)

= 2h + 4g - g + h

= 3h + 3g

= 3(h + g)

Hence, the simplification by combining like terms of 2(h + 2g) - (g - h) is

3( h + g).

Using an arithmetic sequence, it is found that the perimeter when 106 triangles are put together is of 108 cm.

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

The perimeter of a figure is the sum of the outer sides of the figure. Hence, considering that all sides are 1 cm long, we have that:

Hence the first term and the common difference are given as follows:

[tex]a_1 = 3, d = 1[/tex]

Hence the 106th term of the sequence is:

The 2nd and 3rd term of an AP is found to be (a₂ = 95) and (a₃ = 110).

In Arithmetic Progression, the difference between the two numerical orders is a fixed number (AP). Arithmetic Sequence is another name for it.

We'd come across a few key concepts in AP that had been labeled as:

As shown below, the AP can also be referred to in terms of common differences.

Now, the given sequence is; 80, _, _, 125.

The series comprises of four given terms.

Let the first term be 'a₁' = 180.

The second term be 'a₂'.

The third term be 'a₃'.

And, the fourth term is 'a₄' = 125.

Use the nth term formula to find the common difference 'd'.

n-th term:  an = a + (n − 1) × d

a₄ = a + (n - 1)d

125 = 80 + (4 - 1)d

45 = 3d

d = 15

Thus, the common difference is 15.

The second term is calculated as;

a₂ = a₁ + d

a₂ = 80 + 15

a₂ = 95.

The third term is estimated as;

a₃ = a₂ + d

a₃ = 95 = 15

a₃ = 110

Therefore, the 2nd and third term of an AP is computed as 95 and 110.
