You are making a poster to support your friend for homecoming. Your original photo is 4 inches by 6 inches. You want the photo on the poster to be 3 feet by 4/12 feet. What is the scale factor of this dilation?

9

Step-by-step explanation:

Given that:

Dimension of Original photo = 4 inches by 6 inches

Intended dimension of model = 3 feet by 4 1/2 feets

Converting from feets to inches :

1 foot = 12 inches

Therefore,

Intended dimension of model :

3 feets = (3 * 12) = 36 inches

by 4 1/2 feets = (4 1/2 * 12) = 54 inches

Hence, scale factor required :

36 /4 = 9

54 / 6 = 9

Scake factor = 9

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

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
