Ascale on a blue print drawing of a house shows that 666 centimeters represents 333 meters. what number of centimeters on the blue print represents an actual distance of 272727 meters? ''

545454

Step-by-step explanation:

This is a ratio.  you take 666/333 = x/272727.  Basically tis says 666 cm to 333 m is equal to some number of centimeters to 272727 meters.  Then just solve for x.  272727(666/333) = 545454.

Another way of looking at it is what did we multiply 333 by to get 666.  Answe is 2, so we do the same  for 272727.  2*272727 = 545454

If you wanted to you could have also converted units so everything was in either centimeters of meters, but as long as you keep things in the right order this works.  

the number of centimetres is 54cm

Step-by-step explanation:

Given that 6 centimeters represents 3meters.

The number of centimeters on the blue print that will represent an actual distance of 27meters will be Y

6 : Y = 3 : 27

That is

6/Y = 3/27 = 1/9

Cross multiply

Y = 54 cm

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.

5.5
