Jacob is tiling his square walk with square tiles. he is able to fit 5 tiles up and 5 tiles across. if each tile has a length of 3b, what is the perimeter of the wall?

The perimeter of the kitchen wall = 60 b

Step-by-step explanation:

The number if tiles used in the length side of the square walk = 5 tiles

The length of 1 tiles  = 3 b

So, the length of 5 tiles = 5 x ( Length of 1 tile)  

= 5 x (3 b)  =  15 b

So, the length of the square walk = 1 5 b

Perimeter of SQUARE  = 4 x SIDES

⇒ Perimeter of the wall  = 4 x (Side)

                                        = 4 x (15 b)  = 60 b

Hence, the perimeter of the kitchen wall = 60 b

10 * 563.67 = 5636.7

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
