An architect represents a 9 inch height as inch on a scale drawing.

which of the following scales did the architect use?

1 foot = inch
1 foot = inch
1 foot = inch
1 foot = inch

1 foot = 1/3 inch

Step-by-step explanation:

The correct question is

An architect represents a 9 inch height as 1/4 inch on a scale drawing. which of the following scales did the architect use?

1 foot = 1/36 inch

1 foot = 1/3 inch

1 foot =1/9 inch

1 foot =1/2 inch

we know that

To find out the scale drawing, divide the measure in the drawing by the measure in the actual

so

Remember that

so

substitute in the scale drawing

That means

so

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.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
