Answer:

Step-by-step explanation:

Let,

t1 = 27

t2 = 18

t3 = 12

t2 / t1

= 27 / 18

= 3 / 2

t3 / t2

= 18 / 12

= 3 / 2

Common ratio = 3 / 2 = 1.5

t4 = t3 / 1.5

= 12 / 1.5

= 12 x 2 / 3

t4 = 8

For each peak, the ball decreases it's height from the ground by 1 / 1.5 times, Using sequence, we can find the height of ball from the ground for different levels of peaks.

Here, we may use Geometric Progression

The sequence follows as:

27, 18,12,...

The first term (a)= 27

27/18 = 18/12

common ratio = 1.5

Let fourth term be x

Therefore , 12/x = 1.5

=> x= 12/1.5 = 8

Luke has 48 books.He puts 7 books in a box.How many boxes can he fill?explain how you interpreted the remainder

Alex17521 [72]

48 books divided by 7 books per box. So since 7 can go into 48 6 times to make 42, the remainder is 6 books are left out. 6 boxes are filled. I interpreted the remainder by subtracting 42 from 48. And that's all I did. :)

I hope you like this answer and have a good night! :D

What is 100/7 divided by 4 1/3 simplified if you answer thank you and happy holidays

SVETLANKA909090 [29]

Answer: 300/91

Step-by-step explanation:

1. Convert 4 1/3 to an improper fraction

13/3

2. Divide, using the keep, change, flip method to divide fractions

- Keep the first fraction the same (100/7)

- Change the division sign to a multiplication sign

- Flip the second fraction (13/3 -> 3/13)

3. Plug-in and evaluate

100/7 * 3/13

300/91

If you are looking for the solution as a mixed number, it is 3 27/91

4. Simplify, if applicable. This fraction cannot be simplified any further.

Infinite over E n=1 4(0.5)^n-1

yan [13]

Answer:

S = 8

Step-by-step explanation:

An infinite geometric series is defined as limit of partial sum of geometric sequences. Therefore, to find the infinite sum, we have to find the partial sum first then input limit approaches infinity.

However, fortunately, the infinite geometric series has already set up for you. It’s got the formula for itself which is:

$\displaystyle \large{\lim_{n\to \infty} S_n = \dfrac{a_1}{1-r}}$

We can also write in summation notation rather S-term as:

$\displaystyle \large{\sum_{n=1}^\infty a_1r^{n-1} = \dfrac{a_1}{1-r}}$

Keep in mind that these only work for when |r| < 1 or else it will diverge.

Also, how fortunately, the given summation fits the formula pattern so we do not have to do anything but simply apply the formula in.

$\displaystyle \large{\sum_{n=1}^\infty 4(0.5)^{n-1} = \dfrac{4}{1-0.5}}\\\\\displaystyle \large{\sum_{n=1}^\infty 4(0.5)^{n-1} = \dfrac{4}{0.5}}\\\\\displaystyle \large{\sum_{n=1}^\infty 4(0.5)^{n-1} = 8}$

Therefore, the sum will converge to 8.

Please let me know if you have any questions!
